They're So Darn Cute!

 

The weather is warming, the trees are in bloom, and the allergies are kicking in.  (If you're in the Northeast and are still buried in snow, hang in there – spring is coming!  It may be coming slowly, but it is coming…)  With these changes come critters guaranteed to elicit a few "awwwws" among wildlife lovers: baby animals.  Who amongst us does not love to watch the miniature versions of their more majestic elders romping and playing, learning to fly, or following along obediently behind mom?  And what wildlife photographer would not love to capture in-camera a few of the more precious moments?  Like any wild animal, though, wild babies must be respected as the untamed creatures they are. 

 

The temptation to get right up to a wild baby to get a good photograph is often strong, but is never a good idea, either for you or the baby.  Where there is a youngster, mom is sure to be close, even if you can't see her – and if she isn't, you can bet dad or an aunt is.  Regardless of the species of animal, rest assured that the adults can hurt you, and will often try to while defending their offspring against the threat that your presence poses.  Even setting aside the larger, more obviously dangerous animals, you should not consider yourself immune from attack.  Anyone who has ever been dive-bombed by a bird can attest to how unnerving that experience is – especially if you get a set of talons upside your head.  Even if mom doesn't attack, baby might.  What the little ones lack in jaw strength, they often make up for in super-sharp teeth and beaks.  Even innocuous-seeming animals like ducklings can do a number on your fingers: depending on the species, they may have serrations or even a nail-like protuberance on their bills.  And just remember those sharp front teeth when you are thinking of sneaking up to a baby squirrel or rabbit.  Even little baby bites hurt.  (This is one of the reasons why, whenever you do handle a baby animal, such as replacing a fallen baby bird back into its nest, you should always wear gloves.)

 

The dangers to the babies of you getting too close while photographing them are many.  Your presence may cause fear and anxiety to swell in baby animals.  Their heart rates and stress levels may skyrocket, though they may barely be able to move on their own yet.  In some species, it is actually possible for them to die of fear.  Panic can lead to more tangible dangers, too: automobiles in a road the youngster just darted into, the panes of a window it hit while trying to fly away from you.  Assuming the absolute best of all scenarios, in which you are not attacked and the baby is not stressed by your presence, there is nonetheless a major issue to consider: many wild parents will not return to their offspring when people or domestic pets are near.  Newborns of all species need to be kept warm and fed frequently, and even older offspring depend upon the nourishment and protection their parents provide, though the feedings may be less frequent.  Keeping the parent(s) away from a wild baby is a sure-fire way to injure it.   

 

So how do you get that great, detailed shot?  In short: telephoto lenses.  I consider telephoto lenses among the most important pieces of my gear, because they allow me to get up-close and personal without interfering with the natural rhythm and order of things.  The animals are safe from me, and I am safe from them.  Whether I am a hundred yards away from a lion or twenty feet from a robin's nest, telephoto lenses allow me to observe the lives of animals without disturbing them.  Am I telling you to go out and buy an expensive camera body and an even more expensive lens to go with it?  Not at all.  I am telling you, however, to make use of your camera's built-in zooming capabilities, which roughly mimic the effects of telephoto lenses.  Even smart-phone cameras can zoom now.  Give the youngsters plenty of room, use that zoom, and of course, keep a sharp eye out for mom.  One of the best rewards for shooting this way instead of getting right up next to the babies is that you will often have the chance to capture images of mom and babies interacting.  As in all wildlife photography, if your presence is causing the babies or their parents to change their behavior, you are too close.

 

Unless you are hiking in bear country and trying to keep from surprising one of the bruins, you should also be quiet when photographing wildlife, whether adult or young.  Many animals can hear very well, and trust me, you are not a natural sound.  Do not talk to the animal or make sounds at it in an attempt to get it to look your way.  Human voices will put most animals on alert.  So, too, will many "human" scents: perfumes, aftershaves, even scented laundry detergents can cause distress in wild animals.  The human sense of smell is practically non-existent compared to most of the animal kingdom, so don't assume that just because it's a light scent, it won't affect the critters.  Both sounds and smells can add to the animals' stress levels, further contributing to the dangers described above. 

 

Um, Where's Mom?

You've kept your distance, been quiet, and not worn anything scented.  Your reward is some wonderful images of the youngsters.  Throughout, you have watched and waited for mom to return, but she hasn't.  You begin to wonder if the babies have been abandoned.  After all, it's been at least an hour…

 

It is very common, when humans find baby animals without a parent near, for us to assume that the little ones have been abandoned or that the parent(s) have been killed.  Our own protective instinct kicks in, and we want to help them.  After all, we can't just leave them, can we?  Yes.  We can, and we usually should: very much more frequently than not, the babies have not been abandoned, and they are just fine.  They may be chirping, squawking, grunting, or whining, but just like human infants and toddlers making their myriad coos and whines, these sounds do not mean that the animals are in any danger.  As for the parents, we seem to forget that they need to eat, and that they need to gather food for their offspring.  Lacking grocery stores, this can take a while.  It is also imperative when their little ones are still quite small that the adults handle the shopping on their own, without kids in tow.  There is often another critter around who would love to put the youngsters on its own shopping list if they were to come into the open.  So off the parent goes, in search of nourishment.  The hardest thing for us humans to wrap our heads around may be the length of time that some species leave their offspring while on a snack run.  Seals, for example, may leave their pups ashore for up to 48 hours before returning to feed them, while sea lions may be away for 72 hours.  It breaks our hearts to hear the whining and crying of the little ones, and we feel we simply must do something.  This is the natural rhythm of these species, though, and we underestimate the damage we can do in our naïveté.  Imagine you lay your own little one down for a nap, then go to the kitchen to grab a bite to eat.  When you return, your baby is gone, snatched away because someone thought it was abandoned. 

 

It can be very hard for some of us to control our natural care-giving instincts.  Especially if the baby is somewhere you can keep an eye on it for awhile, though, and it is safe from domestic dogs and cats, the best thing you can do is often to wait and watch, educating yourself about the habits of the species in the meantime.  You will then be able to make a much better judgment about when to interfere.  Contacting a wildlife rehabilitation center is a great way to get guidance.  Trained personnel can help you decide what, if anything, should be done.  You can find a wildlife rehabilitation center in your area by contacting the National Wildlife Rehabilitators Association at www.nwrawildlife.org or calling your local animal control.

In-Camera Color Control

 

As the weather cools from the blistering heat of summer, leaves begin their annual, dazzling bursts into full color.  Reds, oranges, and yellows decorate the tree lines like wrapping paper on an eagerly awaited gift.  The goal of autumn photographers is almost always to capture these brilliant hues before they fade into the dull browns and grays of winter.  In the days of film, a photographer would choose a particular type of film to enhance these colors.  Fortunately, the digital age has made it very easy for today's photographers to do the same – without ever getting near film or image processing software such as Photoshop.  Sure, you can always enhance or change colors through your computer, but if you can get the image you want right out of the box, that leaves you with more time behind the camera and less behind a desk.  I have yet to meet a photographer who prefers being behind a desk.

 

A great many digital cameras today, from high-end DSLRs all the way down to point-and-shoots, allow you to change the intensity of the colors you capture.  There are often four different "styles" from which to choose: standard, neutral, vivid, and monochrome.  You can consider each a template, generally designed for a particular purpose but able to be utilized in a wide variety of circumstances for creative effects.  Standard is often used in product photography when a realistic, not too subdued and not too bright color palette is desired, while neutral is often used for portraiture to help even out skin tones and lower contrast.  Monochrome allows you to take those old-fashioned looking sepia images that can be wonderfully nostalgic – and you aren't limited to sepia.  Many cameras offer multiple monochrome hues to play with.  How about blue, green, or purple?  My camera offers 7 different hues within each tone, too…  But for autumn colors, vivid is the setting that you are looking for.  Vivid does exactly what it sounds like: it makes the colors pop, enhancing strong, bright hues.  Many cameras also offer you the option of choosing how saturated you want the colors to be, giving you options from -3 to +3.  Some consider +3 to be oversaturated and unrealistic, while others absolutely love the effect.  Begin at 0, then work your way both up and down the scale to find the color style that you most like for whatever you are trying to capture.  In case that isn't enough fun, you can also adjust contrast and sharpening, and in some models, brightness and hue as well.  What a treasure trove of effects, all without leaving the camera!  

 

This option is usually buried in the menu folder somewhere, but it shouldn't be too difficult to find.  In Nikon cameras, it is called Picture Controls, while Canon's more recent cameras call it Picture Styles.  (They can never agree on anything.  Ever.)  Other camera brands will call it yet something else; check your owner's manual for the specifics.  That being said, if you know what you are looking for, it is pretty easy to locate.  The following is how to find Picture Controls in Nikon cameras; other brands should be similar.

 

Press Menu.

Go to the Shooting Menu (little camera icon on the left).

Push the right arrow to get you into the Shooting Menu options, then scroll down to Set Picture Control.

Push the right arrow again to get you into the Picture Control options.

 

From here, you can choose one of the four styles mentioned above.  Scroll up or down to get to the option you choose, then push the right arrow to get you into that style's options.  Choose your settings, then push OK.  If you skip this last step, your choices will not be saved, and the camera will revert to whatever its previous setting was.

 

Now that you know how to saturate colors, go out and capture some autumn beauty.  But let's not forget that Halloween is also just around the corner.  The range of Picture Control options can help you create eerier, creepier, bleaker images, too.  So whether you want to create bright, happy images or dark and brooding ones, autumn provides a great excuse to get to know your in-camera color controls.

 

                                                                                                                                                    

 

PAWSwalk Success

 

In September, I was fortunate enough to be one of the photographers for PAWSwalk, a fundraising event for my local animal shelter and wildlife rehabilitation center, appropriately named PAWS (Progressive Animal Welfare Society).  Every year, hundreds of PAWS supporters come out to the park to show their support, walk with their furry friends (mostly dogs), try the canine agility course, watch training exhibitions, play games, enter contests, and drink beer and mimosas.  (Hey, we know how to have fun.)  The event was a huge success, surpassing the fundraising goals by more than a bit.  The money and resources donated go to helping companion animals find good homes, and to nurturing and mending orphaned and/or injured wildlife that are then returned to the wild.  Needless to say, the latter goal is particularly close to my heart.  If you are an animal lover and have a little extra time on your hands, I would highly recommend volunteering at an animal welfare group in your area.  If you are fortunate enough to have a wildlife rehabilitation center in your neighborhood, so much the better!  (Know, however, that at any rehabilitation center focusing on releasing the animals back into the wild, you are likely to have very little hands-on contact with the animals.  The goal is to keep the animals from getting habituated, or accustomed to people, as this could lead to big trouble for the animal later.)  If you don't have the extra time but would still like to help, I would imagine that most places would be very grateful for donations, and it doesn't even have to be the monetary-kind.  Old towels and blankets, cat and dog toys, plastic bags…  You would be surprised what is useful to these organizations.  PAWS uses lots of empty yogurt containers, hundreds of hot dog wieners, and even bowling pins to aid the animals.  If you are cleaning out the garage, kitchen, or linen closet, contact your local agency to see if they can use any of your old stuff.  The animals will thank you.

Fun Facts

 

As Halloween approaches, a particular furry animal serves as a symbol of the season.  Who does not associate All Hallow's Eve with the oft misunderstood black cat?

 

-      More black cats are male than female.

-      Black panthers are not uniformly black.  If you look closely, you can see their spots.

-      An Italian black cat named Tommaso made it into the Guinness Book of World Records when his owner left him $13 million in her will.

-      Not all black cats are so lucky.  Due to the superstitions surrounding them, it is widely thought that black cats have a 50% lower chance of being adopted from a shelter.

-      All cats' eyes are huge in relation to their overall head size.  This leads to several interesting phenomena related to focusing.  First of all, cats generally cannot focus on anything within about a foot of their face.  Secondly, their enormous eyes have difficulty adjusting their focus from near to far and back.  This leads a cat's eyes to develop based on environment: inside cats tend to be nearsighted, while outdoor cats tend to be farsighted.

-      Wonder why your cat is not interested in chocolate?  It is one of the few animal species that cannot taste sweet.

-      Experts believe that cats were first domesticated somewhere in the Middle East around 9000 years ago as a result of grain cultivation.  Cats were welcomed as pest control in the fields.

Forest Regeneration Post-Fire

 

The effects of a major forest fire, even one that touches no man-made structures, can be awe-inducing, touching off feelings of utter devastation and destruction.  One need only remember the immediate aftermath of the massive Yellowstone fires of 1988 to feel the ache in the pit of one's stomach.  Or, as it is once again wildfire season, you may only need to go for a short drive to see the blackened skeletons of previously lush forests and grassy fields, depending upon where you are.  (Please stay a safe distance from any actively burning fires.  There is no need to add to the danger to yourself or anyone who may come to rescue you by getting too close.  And remember that wildfires can jump large spans quickly, especially in dry, windy conditions such as we have in Washington State right now.  Roads and rivers are not guaranteed fire breaks!)  But the devastation wrought by fires is never permanent.  Nature always comes back.  Indeed, fire has been a part of the natural regeneration cycle of forest and grasslands far longer than mankind has been around trying to control the blaze.

 

Fire serves several key functions in the forest ecosystem.  It can reduce or remove entirely the duff, which is the accumulated layer of dead leaves, tree fall, etc. that covers the forest floor.  This enriches the soil by returning nutrients to it, while simultaneously clearing space for new seeds to sprout.  Fire also destroys some or all of the crown, the foliage at the top of the trees that makes the forest "roof."  This allows sunlight to penetrate to the forest floor, which can help some of those new seeds to sprout.  Wait, you say, doesn't the fire destroy those seeds?  How can they germinate?  Those answers, like fire itself, are complex.

 

Many seeds are buried deep in the duff layer and in the soil below the duff.  The duff insulates the seeds and the soil from both cold weather and heat – including fire.  If a fire is not too hot or is fast moving, much of the duff layer can remain intact, replete with lots of eager-to-sprout seeds that now have access to a great deal more water and sunlight.  If a fire is slow moving and very hot, however, it can burn the entire duff layer, destroying any seeds within it, and exposing the underlying soil to temperatures that may be so hot that many seeds within that soil are also destroyed.  Rarely, though, are all of the seeds destroyed.  Some plant species (raspberry, plum, and chokecherry, among others) have evolved seeds that count on fire to germinate them: their seed coats are extremely hard and need the intense heat of a fire to break them open.  Other species, like the jack pine, have cones that are sealed by a resin that protects the seeds.  Fire melts the resin, allowing the cone to open and the seeds to disperse, often with the assistance of a hungry critter or a blowing wind.  (Hypothetically, even if every seed in the forest were destroyed, it would not take long for new life to begin sprouting.  The rich soil created by the fire would soon find itself hosting myriad seeds deposited by winds, birds flying overhead, and rodents.  They are nothing if not natural seed dispersants.)

 

Seeds that are still on trees when a fire occurs may nonetheless survive the blaze.  The ponderosa pine has long needles that insulate the cone buds to a certain degree from fire.  (On conifers, the longer the needles, the greater the chance the buds will survive.)  The tough "scales" on a live cone serve as additional protection from heat, as anyone who has ever tried to burn a green pine cone can attest.  They only become easily flammable once open and dry, long after the seeds have dispersed.

 

Depending upon the type of forest, trees can regrow even without the involvement of seeds.  Some trees, such as aspen, have an extensive root system that connects all of the members of a stand of trees together.  These trees are actually all part of a single living organism, not separate trees, though they appear to us on the surface to be individual trees.  When this type of tree burns, the root system is often left unharmed, and new "suckers" shoot up quite rapidly, replenishing the stand in short order.  This is also why it can be very difficult to remove such species from an area where they are not wanted.  Even if you cut down every "tree," unless you kill the root system, suckers will continue to sprout. 

 

Other trees may survive the fire, though much of their foliage is gone.  Along with extensive root systems, thick bark can help protect trees.  Between the inner bark layer and the sapwood is what is known as the cambium, a layer constituting the vascular system of the tree's trunk.  A healthy cambium is critical for the tree's survival.  The thicker the layers of inner and outer bark, the more protected the cambium is.  While some tree species have a naturally thicker bark than other species, the age of the tree is important, too.  Older trees, with their thicker bark, tend to fare better than younger trees.  (Any connection to people "growing thicker skin" is, I'm sure, purely coincidental.)

 

Okay, so the plant life takes care of itself, I hear you saying.  What about the critters?  Let's start at the bottom: bugs love burned forests!  They have a ton of food, especially those species that are wood-boring or that find the taste of rotting plants particularly appetizing.  Life is grand for a wood-boring beetle after a fire!  Except for all of the beetle-larvae-eating wildlife that moves in shortly after the beetles do.  Many species of birds flourish in burned-out forests precisely due to the fact that they have an abundant food supply and many new nesting holes created by the fire.  These nesting holes also create new homes for small animals such as mice, squirrels, and chipmunks.  Larger holes, fashioned by hollowed out, fallen logs, create good homes for medium-sized critters such as raccoons and foxes.  All of these eventually draw predators such as wolves, wildcats, and birds of prey back into the regenerating forest.

 

Elk will eat the bark of burned lodgepole pine trees, but not the bark of healthy pines.  Live pines produce chemicals that make their bark unpalatable to elk, while fire destroys these chemicals.  Fire also makes the bark more digestible, increases its protein levels and concentrates some minerals.  Perhaps more importantly, burned bark is a very easy source of food.  Wild animals, particularly in winter, cannot afford to work hard to find food.  Their calories must be well-spent, not wasted.  Burned forests provide a winter buffet for elk trying to survive the lean season.  In the spring and summer, elk and other ungulates such as moose and deer benefit from the improved shrub growth after a fire, and their populations often amplify markedly in the years after a major burn. 

 

Bears, also, can benefit from burned areas.  Though they are often thought of as vicious carnivores, bears are actually omnivores whose diet consists primarily of berries, grubs, and flowers.  Fires regenerate berry bushes and flowers through the mechanisms described above, and the dead trees are grub heaven for bears.  Not only are fire-killed trees full of larvae and grubs of all kinds, they are also easier to pull apart than live trees, allowing access to the feast just below the surface with minimal effort.  Like elk, bears are in this for survival, and the easiest food sources tend to be the preferred ones.

 

This is only a short overview of how a forest regenerates itself after a fire.  Depending upon the type and location of the forest, the details will change, sometimes dramatically.  Nonetheless, fire is often an important component of the life cycle of a healthy forest.  It constitutes both an end and a beginning, a transitional phase that allows the forest to restore its nutrients and reset its balance.  In the end, the forest will be healthier for it.  Even in Yellowstone.

Fun Facts

 

It's hot out there!  July and August are typically the most brutal months, heat wise, in the northern hemisphere.  But humans aren't the only critters that have to deal with the heat.  Here are some fun bits about how temperature affects a few of our fellow creatures.

 

·         Toucans regulate their body temperature by controlling the blood flow to their rather oversized beak.  The large surface area allows heat to escape quickly.  When they sleep, toucans tuck their beaks beneath a wing, effectively becoming their own blanket.

·         Similarly, elephants regulate their body temperature through blood flow to their large ears.

·         Wonder how hot it is, but don't have a thermometer?  Do you have a watch – and a cricket?  Count the number of chirps the cricket makes in 15 seconds, then add 37.  You now have the approximate temperature in degrees Fahrenheit.

·         Water temperature affects how long sea turtles can hold their breath.  Colder water allows them to hold their breath longer – sometimes for hours.

·         Temperature determines whether an alligator hatchling will be male or female.  Above 93° F means all the hatchlings will be male; below 86° F, they will all be female.  Temperatures in between will result in a mixed brood.  So there is some truth to "cold-blooded women," at least in the alligator world.

·         Think various types of hibernation only occur in winter?  Think again.  In very hot, arid environments, many creatures go into a state of torpor characterized by inactivity and low metabolic rates similar to winter's more well-known long sleep.  In summer, this hibernation is known as estivation.

Tying It All Together: Shutter Speed, Aperture, and ISO

 

Now that we have covered the three basic elements of exposure individually (ISO - November, 2012 newsletter; shutter speed – March, 2014 newsletter; and aperture – April, 2014 newsletter), let's look at how they work in combination to give a properly exposed image.

 

All three control how much light hits your camera's sensor (or film), and each has its own function.  But how do they affect each other?  To explain it, let's once again go back to our window analogy, but this time, we need to add an additional element.  Instead of simply trying to get a certain amount of air into a room, let's put a tabletop windmill in front of the window.  Our goal: to make the windmill complete a set number of revolutions (let's say 10) -- a proper exposure.  We know that aperture is the equivalent of how far we open the window, while shutter speed is how long we leave it open.  We can throw the window wide open, let in a lot of air all at once and reach those 10 revolutions quickly.  This also requires that we close the window quickly, before we reach 11 revolutions (or the windmill gets overexposed).  This scenario is the equivalent of a large aperture and a fast shutter speed.  Conversely, we can open the window only a little, which requires that we leave it open longer to reach the same 10 revolutions.  If we close the window too soon, we will not have reached the magic number of 10 (the windmill will be underexposed).  This is the small aperture, long shutter speed scenario.  But wait, you say, doesn't the speed of the air moving through the window also help determine how fast the windmill reaches 10 revolutions?  Excellent catch!  Indeed it does, and this is where aperture comes in.

 

In this analogy, the strength or speed of the air moving through the window is the equivalent of the strength, or brightness, of the light hitting the camera sensor.  The ISO would be the equivalent of the resistance, or sensitivity, setting of the windmill.  If there is a very strong wind (a very bright light), you would likely want the windmill's sensitivity to the air current to be low so that the windmill does not spin way too fast (again, an overexposure).  But if the air current is weaker (the light is dimmer), you would want the windmill to be more sensitive to what little air movement there is, so that you can actually complete the 10 revolutions (otherwise, you end up with another underexposure).  Thus, for a brighter light, you want a lower ISO number, meaning a lower sensitivity to light.  For a dimmer light, a higher ISO with its greater sensitivity to light is generally required. 

 

How do all of these pieces fit together?  To maintain an equivalent exposure, if you manipulate one setting, you must manipulate another, though which one is up to you.  Say your window is open halfway for ten seconds, with a given windmill sensitivity.  You want to open the window all the way, doubling the amount of air coming in at once.  To maintain a 10 revolution "proper exposure," you can cut the time the window is open in half, to five seconds, while maintaining the same windmill sensitivity.  Or you can leave the time the window is open the same and reduce the windmill sensitivity by half.  (You can also reduce the strength of the air current coming through the window, i.e. dim the light source, but that is a topic for another day.)  As long as the overall total amount of light hitting the sensor is the same, the exposure will be equivalent.  The images may be very different, with vastly different depths of field, etc., but the exposures will be the same.  Just remember that to get a proper exposure, you need to hit ten revolutions of the windmill.  How you do that is entirely up to you.

 

Does this mean that you will always want a perfectly exposed image, that exact series of ten revolutions, no more, no less?  Not by a long shot.  But once you understand how the elements of a proper exposure work, you can then work creatively to craft stunning images that do not fit the strict definition of being "properly exposed."  Should you decide that any particular image would have a greater impact by being underexposed, you will understand how to manipulate the elements of our window to stop the windmill after only eight or nine revolutions.  Similarly, if an overexposure would give your image that pop you are looking for, you will know how to make that windmill keep spinning right on past ten, not stopping until it reaches eleven or twelve (or seventeen…) revolutions.  Mastering these three elements, shutter speed, aperture, and ISO, is truly the key to mastering exposure.  And once you master exposure, those creative doors fly wide open.  Suddenly you are able to construct amazing images intentionally, and not just chance upon them by accident with no hope of recreating them.

 

Test yourself.  Play with the elements of our window and windmill and try to get equivalent exposures with different settings.  Then see if you can create intentional under- and overexposures with multiple settings.  Finally, and most importantly, have fun!

Fun Facts

 

First, the serious side: we are approaching that time of year when nature, when angry, shifts her focus from blizzards and mudslides to violent winds, drenching rains, and unbelievable flooding: hurricane season.  Without fail, some of the most arresting photographs to be produced each summer and fall come from areas affected by hurricanes.  While we cannot prevent hurricanes, we can prepare for them.  The National Oceanic and Atmospheric Association (NOAA) has designated May 25th through May 31st as National Hurricane Preparedness Week.  Go to http://www.nhc.noaa.gov/prepare for some great information on hurricanes and cyclones and how to prepare for them.  (Perhaps their most poignant advice, especially for photographers, is simple: "The first and most important thing anyone should do when facing a hurricane threat is to use common sense."  Sometimes we photographers let our common sense go out the window in our quest for great images.  Remember, be safe.  You can only create great images if you are alive and well.)

 

 

Now the fun side: ever wondered how tropical storms get their names?

 

* The practice of giving tropical storms women's names began in the late 19th century, became commonplace during World War II, and was made official in 1953.

* It was not until 1978 that men's names were included in the rotation.

* There are three major storm-naming regions in the U.S.: the Atlantic, the Eastern North Pacific, and the Central North Pacific.  On the U.S. mainland, we are most familiar with the Atlantic region.

* You may know that a list is prepared prior to each storm season with names in alphabetical order, and as storms appear, they are given names in that order.  Did you know, however, that the list is different for each region, that there are only six lists per region (or four, in the case of the Central North Pacific region), and that they are rotated through?  In the Atlantic region, for example, the first named storm of 2016 will be "Alex."  "Alex" was also the first storm of 2010, and assuming the 2016 version isn't damaging enough to have the name retired, "Alex" will also be the first storm of 2022.

* If a storm causes significant damage to life or property, its name can be retired, to be replaced by another beginning with the same letter.  The most names retired in a single year: five, in 2005.  Those names?  Dennis, Katrina, Rita, Stan, and Wilma.  The following year, no names were retired.
