RAS Membership Meeting May 18, 2015 “Yellowstone in February” Dan Streiffert Meeting begins at 7:00 PM. This presentation is from a trip I made in February, 2015 to West Yellowstone. I spent 5 days on a photography tour with John and Barbara Gerlach. Each day we toured the park via two snow coaches. Our destinations were dependent on wildlife and weather. We visited Old Faithful, The Grand Canyon of the Yellowstone, and Norris Hot Springs. Following this, we drove to Gardiner, MT and spent two additional days touring the Lamar Valley and Mammoth Hot Springs by car. This was a low snow year with very mild temperatures, but we still managed to get some good photos. We encountered elk, bison, beaver, coyotes, a bobcat, wolves, wild turkeys, and much more. Join us at 6:30 for coffee and conversation.

In case you haven’t heard the news, the state Fish and WildlifeCommission voted on Friday to list the tufted puffin as a stateendangered species. I’d like to extend a sincere thank you to youand your board members for taking the time to let the Commissionknow the importance of this step. Having testified along with BlackHills Audubon member Elizabeth Rodrick at the Commissionmeeting back in February, I can tell you that WDFW staff were verygrateful for our involvement.

Of course the reasons behind the puffin’s decline are complex andsimply listing the bird won’t erase this fact. However, we can usethis listing to help bring attention to the plight of this bird and tohighlight its existence in our region. It also means we have work yetto do – our next step will be to ensure that the department movesquickly to develop and enact a recovery plan for this iconic bird.

Here’s a link to the tufted puffin status review in case you’d likemore information.

I have a new bird hanging out in myyard whom I have named PiebaldPete. He is a leucistic Dark-eyed

Junco. His abnormal white nape featherslook like he has eyes in the back of hishead. Watching him, I wondered about hispigment challenged feathers and howexactly it happened? I wanted to learnmore about leucism and I found aninteresting discussion about it in the newsecond edition of David Sibley’s TheSibley Guide to Birds.

Sibley points out that many birders usethe term leucistic to refer to birds that lackmelanin from some or all feathers, as wellas using leucism to refer to birds that havedilute plumage (which gives the fadedlook). However, current scholarlypublications (Buckley 1982, van Grouw2006) define leucism as total lack ofmelanin from some or all feathers. Sibleycomments that we lack a simple umbrellaterm encompassing all forms of reductionof pigment in birds. Sibley puts forth anargument that the term partial albino,would be more accurate than leucism,seeing as albinism is already usedcommonly for non-melanin producingbirds. Sibley states that when one is out inthe field and spots a bird with abnormalplumage, identifying whether a bird is notproducing melanin pigment, has areduction of melanin pigment, or has aproblem depositing melanin on newfeathers is impossible. Many conditionscan cause abnormal plumage likeenvironmental and genetic factors. Aswell, the conditions can be temporary orpermanent. Often we only see a bird in thefield for a short while and identifying theunderlying cause is difficult.

Considering Sibley’s argument, Irecognize that simply saying that PiebaldPete is leucistic is not necessarilyaccurate. By just observing him, I don’tknow why he has a reduced amount ofcoloration. I would be more accurate insaying that Piebald Pete is a partial albino.I can assume that Piedbald Pete’sabnormal coloration is not from a trauma,as his white pigmentation is bilaterallysymmetrical. However, I cannot specifywhether the white pigmentation is due toinability to produce melanin, or inability todeposit the melanin in the new feathers.

Though Pete was singing away, he didn’tseem to be having any luck garnering amate. I wonder if his lack of coloration inhis plumage feathers is affecting his lovelife. Luckily for Pete, the location of hisabnormal feathers is not on his wings asthe feathers lacking melanin are weakerand wear down more easily, which couldhave an impact on his flying. Regardlessof the underlying nature of Piebald Pete’slack of coloration, it was a treat to havehim visit our yard.

Recent Bird Sightings:Thanks to this month’s reporters Ralphand Sandra Embrey, Ross and AnnetteTabor, and Pamela Phillips.

March 19th, 2015 The Embreys had a lateseason surprise visitor. A female VariedThrush stopped to have a sip of waterfrom their pond before flying on. Sandrasaid “I can’t remember seeing thethrushes in March; usually they are in ourbackyard during November-January.”

March 26th, 2015 Ross and Annette Taborspotted a Townsend’s Warbler in thebushes in their backyard.

March 27th, 2015 Pamela Phillips reportedof spotting Pine Siskins in her yard again.Pamela also saw Downy and HairyWoodpeckers, White-crownedSparrows, Violet-green Swallows, Red-breasted Nuthatches, and a BrownCreeper.

April 8th, 2015 Ralph and SandraEmbrey’s yard remains a popular place forowls. This month, a Barn Owl frequentedtheir yard, “cruising the hillslope andfairway below the house.” Reportedly, theowl has shown up repeatedly between8:15 to 8:20 PM. Sandra commented “Iwonder how many more times I will seethe little brown bunny that has beenhanging around here too.” Other regularvisitors to the Embrey yard this monthwere Golden-crowned Sparrows,Anna’s Hummingbirds, and Downy andHairy Woodpeckers.

Mystery Bird of theMonthThis bird is commonly seen on coniferoustrees. Can you guess the bird? Here arethe clues:

● A group of me is known as a “spiral”.● When threatened, I can freeze and

stand motionless for several minutes.Sometime this can fool predators be-cause I can camouflage with my brownplumage.

● I build a hammock-like nest, under-neath a loose flap of bark.

● Sometimes I nest in odd places such aswindow shutters, fence posts, boxes,and even in concrete blocks.

● Some of my nests can have a pair ofopenings, an entrance and an exit.

● I am a great conserver of energy, foodenergy. On a given day I burn barely 10calories, as opposed to a human whoburns about 2,000. One spider givesme enough energy to nearly climb atree.

● As opposed to my cousin, when forag-ing I hop up a tree and flit down to thebottom of the next tree. My cousinpasses me hopping down the tree.

Book Reviews by Laura Lavington

Last year I visited Mexico twice, and oneach trip I visited a botanical garden.Naturally, I took my binoculars with meand kept my eyes open for birds. As youshall see, the two botanical gardens werequite distinct, and my experiencesdiffered.

In late February last year my momand I flew down to Puerto Vallarta onMexico’s Pacific coast to celebrate mybirthday. After seeing a poster in theairport, I decided that for my birthday itselfI wanted to visit Vallarta Jardín Botánico(maybe because the poster had ahummingbird on it). I was prepared: a fewdays before I had picked up PrincetonIllustrated Checklists’ Birds of Mexico andCentral America by Ber Van Perlo, whichcovers more than 1,500 species. On theflight down I had looked through thepages, reading out loud names of exoticspecies and getting excited. But first,before I could see any unfamiliar specieson my birthday, we had to get to thegarden.

In Puerto Vallarta my mom and I didnot rent a car, but the garden’s websitewas helpful and told exactly how to get tothe garden by bus (the botanical garden isdown the coast a little bit). If you havenever been on a Mexican bus, it can be abit of a cultural experience. The publicbuses in Mexico—or at least in the resortareas—don’t resemble the buses in theUnited States: either the Mexicans like avintage look, or that bus predated WorldWar Two. Anyhow, I’ll let you imagine thetwisting, the turning, and the shaking asthe bus slowly followed the coastline, andI’ll merely say we got to the garden fine.

The bus stopped right in front of thegarden, and an employee immediatelygestured to me to come see a nest. Hedidn’t seem to know much English, but Iknew the Spanish word for hummingbird,and I asked him if that’s what it was.Indeed! The mother had built the nestquite low, and I could look in at the twobabies who filled the nest. Of course, Iwas careful to not get too close, although Idid wonder why she had built it in such alow spot. Later I saw the mother, but I’mnot quite sure what species she was—females are tricky to identify, and theregion has more different species than thetwo we have up here. Oh, before I moveon to telling you about the relaxing lunchwe had several stories up in thehacienda’s restaurant, I’ll mention that aswe bought our entrance tickets I shelledout two hundred pesos for a plasticizedchart of the birds of the Puerto Vallartaregion. Also important: we bought some

insect repellent, as we were advised todo.

My mom and I wandered leisurelyalong the trails for a while, during whichtime I saw an elegant trogon and agolden-cheeked woodpecker. The bestbirdwatching was during lunch, however,for there were feeders a short distancefrom the restaurant. We were up severalfloors looking down at the San Blas jaysand yellow-winged caciques that came tothe fruit that the botanical garden had sokindly provided. There were also severalhummingbird feeders, but I had a hardtime getting photographs of the birds. I’mpretty sure I glimpsed plain-cappedstarthroats and cinnamon hummingbirds.After lunch we wandered around somemore, and even walked down the hill tothe riverside, and I also saw either tropicalkingbirds or great kiskadees (my picturesaren’t great, and my notes are a littleunclear). As we were leaving, I saw agroup of stripe-headed sparrows. Oh,according to my notes I also saw acrested caracara. I definitely enjoyed thevisit to the botanical garden, and I waspleased with the amount we saw. It waspretty hot, though, so after a while wetook the bus back to town.

The trip to the botanical gardenoutside Cancun (on Mexico’s Caribbeancoast) last December was quite different.First of all, I remembered mybinoculars, but I forgot my Mexicanbird book! I was quite frustratedwhen I realized that. I tried to takephotos of the birds I saw so I couldidentify them later, but that systemonly sometimes works. The areahad great promise, too, for I figuredthat the birds we would see wouldoften be different from the ones wesaw on the Pacific coast.

I had found out about theJardín Botánico – Dr. AlfredoBarrera Marin when we only hadone full day left, so the visit therekind of had to be squeezed into theitinerary (we went snorkeling in themorning and didn’t get to the botanical

garden untilmidafternoon).On that tripto Cancunmy sisteraccompanied my momand me, andwow! I feltlike one ofthe three stooges trying to find thebotanical garden (oh, yes, we had a rentalcar—which it seems like would havemake things easy). The garden’s websitedidn’t give directions, and my Garmindidn’t really like the address. I knew abouthow far south the place was supposed tobe, but I had hoped for a sign orsomething. In the end, after we got off thefreeway and back on going in the oppositedirection several times (after I had said “Ithink we’ve gone too far”), we determinedthat the entrance was literally on an off-ramp (of course, we had already passed itthen, and we didn’t dare back up to it). So,by the time we got to the botanicalgarden, the day was significantly into theafternoon (it was December, after all, andeven in Mexico the days are shorter in thewinter). I think we might have seen morebirds had we visited the garden in themorning, but we really couldn’t do muchabout it at that point.

As you may have gathered, theCancun-area botanical garden is a bit off

the beaten track, and we never sawany other visitors there. When wearrived we saw two employees, whotook our money and gave us birdbrochures (in English!), and Iunderstood from them that the gardenclosed in about an hour, but we didn’thave to leave by then… hmm, is thatwhat they said? Then who shuts thegate? There was a general vaguenessabout everything. Well, everythingexcept the (Continued on page 8)

Bird of the Month: American GoldfinchReprint Courtesy of Wild Birds Unlimited, Burien

● Goldfinches are found across North America. The threespecies include the American, Lesser and Lawrence’sGoldfinch.

● Goldfinches are sometimes referred to as wild canaries. Theyare actually in the finch family as their name suggests.

● Northern populations of the American Goldfinch are mostlymigratory and southern populations are mostly residential.

● Banding studies have revealed that some AmericanGoldfinch in Ontario migrate more than a 1,000 miles toLouisiana.

● Female American Goldfinch will stay further south during thewinter than males and younger males will winter further norththan adult males.

● American Goldfinch rarely over-winter in northern areaswhere temperatures fall below 0°F for extended periods.

● Residential flocks of American Goldfinch roam widelybetween food supplies during the winter and have beenrecorded moving over 4 miles between multiple feedingstations in a single day. Other records show movements ofover 30 miles in a single winter.

● American Goldfinch have an interesting flight call consistingof four syllables that can be likened to “po-ta-to-chip.”

● The genus name, Caruelis, is from the Latin word carduus,which means “thistle.” Goldfinches are very dependent onthistles for food and even use thistledown to line their nests.

● The American Goldfinch is one of the latest breedingsongbirds, waiting to nest until mid-to-late summer whenthistle seeds and down are readily available.

● When breeding for the first time, young American Goldfinchwill begin nesting at least two weeks later than experiencedadults.

● Unlike many birds, the American Goldfinch undergoes acomplete molt each spring. This molt requires a large amountof nutrients and energy which probably diminishes theirability to nest earlier in the season.

● American Goldfinch typically have only one brood per year,although veteran females may produce an additional brood.To facilitate a second nesting, a female will leave her originalmate in care of the first brood and find a new male as herpartner for the second nesting.

● It is estimated that there are three males for every twofemales in the population of American Goldfinch. Thisimbalanced ratio may be due to the fact that male goldfinchlive longer than their female counterparts.

● The female American Goldfinch chooses the nest site, buildsthe nest and incubates the eggs all on her own. The malefeeds the female on the nest throughout incubation and takeson an ever increasing role in feeding the nestlings as theygrow older.

● American Goldfinch can weave their nest so tightly that it willtemporarily hold water.

● American Goldfinch attach their nest to supporting twigs withspider web.

● American Goldfinches prefer to nest in habitats with treesand shrubs and usually place their nest 4-10 feet high, oftennear a water source. They will sometimes nest in a loosecolony.

● Goldfinches usually lay 5 pale-blue or greenish-blue eggsthat will hatch in about 12 days. Nestlings will fledge about 12days after that.

● While most Brown-headed Cowbird eggs fool the femaleAmerican Goldfinch and are incubated to hatching, fewcowbird chicks live longer than three or four days. This is dueto the low amounts of protein found in the vegetarian diet ofthe goldfinch.

● Young American Goldfinch are dependent on their parentsfor at least three weeks after fledging. Be sure to watch andlisten for their energetic begging as they harass their parentsfor food at your feeders.

● Female American Goldfinch are dominant over males in thesummer and appear to be subservient to them in the winter.See if you call tell a difference at your feeders.

● American Goldfinch will use almost any feeder, includingones that require them to hang upside down to eat. Studieshave shown their preference is to sit upright at perches onfeeders that are hung in trees above head height.

● American Goldfinch are dominated by Pine Siskin and HouseFinch during the winter and play second fiddle to them atfeeders.

● American Goldfinch are common feeder visitors and preferthistle (nyjer) and shelled sunflower seeds.

● American Goldfinch are rather acrobatic, often dipping upsidedown while feeding on weed seeds such as coneflowers andsunflowers.

● To stay warm on a cold winter’s night, American Goldfincheshave been known to burrow under the snow to form a cozysleeping cavity. They will also roost together in coniferoustrees.

● Unlike many birds, Goldfinches completely molt their featherstwice a year, before breeding in the spring and after nestingin the fall.

Hello and welcome back to mymusings!

I was pawing through some issues ofBirdWatching magazine and noticed anarticle entitled Amazing Birds. It waswritten by Eldon Greij, the founding editorof Birder's World magazine. He exploresand explains fascinating aspects of birdsand their world.

For example, did you know that long agoin prehistoric times birds had teeth? Asbirds evolved and modified their bodiesfor flight, bones were lost, some werefused together and heavy, compact bonewas replaced by lighter, spongy bone.This was most evident in the skull. Thejaws of birds became smaller and moredelicate meaning the teeth had to go. Themolars were replaced by the muscularorgan called the gizzard which grindsfood. This trade off of the teeth and skullfor a gizzard was a smart thing as itdecreased body weight and moved thecenter of gravity under the wings creatinga more aerodynamic weight distribution.

The gizzard is just one part of a bird'sstomach. The other section is in front ofthe gizzard. It's a small, thin-walledglandular chamber that secretes digestiveenzymes and acid.

Fruit- eating birds have weakly developedgizzards. Seed and insect eaters, on theother hand, have a gizzard with thickmasses of muscle that can contract withtremendous force. It is lined with a tough,

grooved and ridged layer of keratin whichis constantly being regenerated.

Birds that have well developed gizzardsinclude turkeys, pheasants, pigeons,doves, ducks and many finches. Seaducks such as eiders and inland diverslike scaup eat mussels and other shellfishthat are easily ground up.

Turkeys can crush pecans, shell and all,in an hour. It has also been reported thata person back in the 17th century tried anexperiment in which glass balls, leadcubes and chunks of wood wereintroduced into a turkeys stomach. Thefollowing day the glass was pulverized,the lead cubes flattened and the woodbadly worn. When a modern researchertried to duplicate these feats with a visehe needed to apply a force of 437pounds!

In birds of prey the gizzard has a differentfunction. Many owls and hawks swallowsmall rodents and birds whole. The non-digestible feathers, bones and fur remainin the gizzard and are compacted into apellet and regurgitated. Grebes ingestfeathers (did you know they feed feathersto their young?!) which settle in thebottom of the gizzard and prevent fishbones from moving into the intestine.

You may have heard that sometimesbirds eat pebbles. These are kept in thegizzard to increase its pulverizing ability.Pebble munching has had someinteresting results. In India, ruby mines

were discovered after a ruby was found inthe gizzard of a pheasant and inOklahoma, a minor gold rush occurredwhen gold nuggets were found in duckgizzards. I guess you could say that theevolution of the gizzard was a gem of anidea!

It seems strange and somewhatoutlandish that losing teeth anddeveloping a powerful, muscular grindingorgan would be associated with the abilityto fly but as Mr. Greij exclaims, "...nothingshould be a surprise when it comes tothe amazing lives of birds."

Until next time,

● During their fall feather molting, AmericanGoldfinches grow a new set of feathersthat are much denser than their summerplumage. These soft feathers provide anadditional layer of insulation to help keepthem warm throughout the winter.

● The color of the legs, feet and bill of theAmerican Goldfinch change with eachfeather molt. In winter plumage, their legs,feet and bill are dark grayish brown. Inbreeding plumage they change to a buffyyellow orange color.

● The American Goldfinch is the state bird ofNew Jersey, Iowa and Washington.

● Of the more than 3 million bandedAmerican Goldfinches, the oldest one everrecaptured in the wild was at least 10years and 5 months old.

BIRDATHONWhat is it?It’s “birding for dollars!” Count as many bird species in one day asyou can! Choose any day in May. Get family, friends and co-work-ers to sponsor you, then go birding! Afterwards, send them a list ofwhat birds you saw, and they will donate X amount for each speciesyou saw (i.e. 25 cents). Or they can just donate a flat fee. 100% of theproceeds support Rainier Audubon activities in south King County.

You can also conduct your Birdathon birding on one of our field trips.Earn money for chapter activities while enjoying a great field trip ledby an expert birder. Or just stay at home and count bird species atyour feeder. Or be creative and come up with your own Birdathonexperience!

Sponsors are happy to support your efforts, and many look forwardto being asked again the following year. They especially enjoy yourlist of bird species seen. We will provide helpful hints, examples ofsolicitation and report letters, prizes for birders, thank-you gifts forsponsors, and one-on-one help as needed.

Why do it? Rainier Audubon needs the money! The portion of yourmembership dues to Rainier Audubon covers only a portion of thecosts associated with running a successful Audubon chapter. Birda-thon is our largest fundraiser, and we depend on it to provide a sta-

ble funding base for our manyactivities and services such as: printingand mailing our chapter’s newsletter,general administrative costs, pro-grams (speaker fees), environmentaleducation activities, conservationcommittee activities, etc., Wewouldn’t want to have to cut back onany of our activities due to lack offunds!

Our goal for Birdathon 2015 is $5,000,which is attainable if everyone helps!

Stay tuned for prize announcements such as most money raised, firsttime birder, and most species seen.

Sponsor sheetsare available atRainier Audubonmembershipmeetings or on-line atwww.RainierAudubon.org.

mosquitos: they were out in full force.The Cancun botanical garden isevidently a smaller affair than the one Ihad visited in Puerto Vallarta, and theydid not sell insect repellent. Hmm, abouta half hour after trudging along the pathwe found that we were literally in amangrove swamp—yep! A perfect placefor mosquitos. In fact, we spent so muchtime fighting the mosquitos that it washard to use our binoculars: every time Iraised either my binoculars or mycamera, I ended up with a bite or four.That kind of scenario makes it hard tospot a lot of birds. I was wearing shortsthat day, and I got so eaten bymosquitos that my legs were polka-dotted—the kind of look that actuallymakes strangers stare.

I actually feel a little cautious aboutcalling that place a “botanical garden” inthat it more resembled the jungle withpaths. At times there were dilapidatedsigns telling what a fern or other was,but I more felt like I was on a hikethrough the jungle. Oh, well, I think my

mom and my sister were wondering“where in the hell has Laura brought us?”but I tried to stay positive. After all, thewooden towers, platforms, and bridgeswere exciting… if less than safe. At onepoint when we were several stories up mysister was clutching the edge of the towerand asked me to take some pictures—evidently she didn’t dare let go. Also, therewere tall skinny trees growing up betweenthe planks of the wooden suspensionbridges—at what point do they remove thetrees?

I did see a few birds on the hikethrough the jungle that shadowyafternoon, though, despite the forcesworking against me. The trogon I saw andphotographed from the back, and I am notsure if it was a female violaceous trogonor a female black-headed trogon (drat!).Also, early on we were nearly knockedover by a speedy hummingbird, but Inever got a good look at the fellow (I knowit wasn’t a mosquito: mosquitos don’tmove that fast). I also have recorded in mynotebook that I saw a commonyellowthroat and a northern waterthrush

(not too exotic there). Actually, theneatest thing I saw was the coatis (or atleast that’s what I think they were).Cat/raccoon-like with long striped tailsstanding up tall. I didn’t get a picture ofthem, though—they moved too fast.Come to find out that the things are ascommon there as raccoons here (andequally crafty).

Lest my recollections of theCancun-area botanical garden make youfeel like it’s not worth visiting theYucatan Peninsula, I will say this: theYucatan is incredibly rich in bird life(albeit birds are hard to spot in thejungle), but you may actually do bettervisiting Chichen Itza or anotherarcheological site than you would visitingthe botanical garden. It was at ChichenItza that I saw the melodious blackbirds,the yellow-backed oriole, and the greatkiskadees—and that was even amongstall the crowds! I think next time I go toCancun I will visit one of the less-visitedMayan sites and look for birds there—but most of all, next time I’ll remembermy bird field guide!

Field Trips (Continued from page 4)

Bird Word Nerd Where did the prothonotary warbler get itsname? I’d read in a novel that prothonotarywas the title of a clerk of the church who worebright yellow robes like the bright yellowfeathers of the warbler. I assumed theCatholic church and did find 2 levels of thistype of office but they wear black and red withpurple capes – no warbler like that! The wordoriginated with the Byzantine court and was inuse from the 7th to the 10th century but I didnot find anything about what color they wore!The word is still in use, sometimes spelledprotonotary, for various clerk positions inAustralia and other countries. The folks whonamed many of our birds were very well-read,well-traveled, well-educated men (yes, usuallymen!) who used their knowledge to distinguisheven small feathered creatures in noble ways!Enjoy!
