    A Cold Day onthe Delta

    by Celeste Hinds

    In spite of liquid blue skies andvery little wind, November 23rd was

    a frigid day on the Delta Explorer.Heavy coats and warm hats helpedto keep the 45 hearty souls warm aswe left the Blakeley Docks andmeandered up the Mobile TensawRiver Delta looking for Osprey andKites. The big birds were smarterthan the Audubon members. Theystayed out of sight, perhapshunkered down in low vegetation.

    A few Great Egrets, Cormo-

    rants, Little Snowy Egrets andplenty of Forester and CaspianTerns were spotted. One NorthernHarrier flew low over the marshes.Laughing Gulls lived up their nameand laughed at the shiveringhumans.

    Captain Robert Estices steeredthe Delta Exploreralong interestingshorelines and pointed out histori-cal sites. He said Osprey nests atoppower structures were badly

    damaged by Tropical Storm Isidorein September.

    Resident botanists, KeithCarter and Melvin Long, looked forexotic wetland plants. Noted birder,Minnie Nonkes, identified GoldenCrowned Kinglets in the brushyarea before we left the dock.

    In spite of temps in the 40sAudubon members and guestsenjoyed a full morning on the DeltaExplorer. By the time the picnic gotunderway, coats were shed andlunch was enjoyed in the sunshine.After lunch Audubon PresidentJohn Borom led some of the groupon a tour of the nature center underconstruction in the northern end ofthe park.

    All in all, a fine day. Brrrrr!!!

    A Plurality ofBirds

    By Celeste Hinds

    Over the years men havecoined a host of special terms to

    describe birds in groups. Hereare some that survive the Englishlanguage. I copied some of thesefrom an old National Geographicand added others as I came acrossthem in different publications.

    A siege of HeronsA gaggle of Geese (on the

    ground)A skein of Geese (in flight)

    A herd of Swans, Cranes orCurlewsA badelyng of DucksA sord (or sute) of MallardsA spring of TealA company of WidgeonA cast of HawksA bevy of QuailA covey of PartridgesA muster of PeacocksA nye of PheasantsA brood of Chickens

    A covert of CootsA congregation of PloversA desert of LapwingsA wisp of SnipeA fall of WoodcockA bazaar of MurresA flight of Doves or SwallowsA murmuration of StarlingsAn exaltation of LarksA watch of NightingalesA chattering of ChoughsA host of Sparrows

    I clip and paste this list inmy field guides. Comes inhandy for impressing newbirders.

    In the coming days, a House-Senate

    Conference Committee is expected to

    make a decision on drilling in the

    Arctic National Wildlife Refuge. Last

    year, the US House of

    Representatives passed a provision

    to open the Arctic National Wildlife

    Refuge to oil and gas drilling. This

    provision was included as a part of

    the overall House energy bill. In

    April, the Senate voted to keep the

    drilling provisions out of its version

    of the energy bill. As the two energybills differ, a Conference Committee

    comprised of members of both the

    Senate and House will make the final

    decision.And now, six months later,

    they appear ready to do so!

    Conference Committee members need

    to be reminded that the Arctic

    National Wildlife Refuge, including its

    coastal plainwhere they look to

    drillhas extraordinary value as an

    intact ecosystem, with all its native

    birdlife. Millions of birds nest, migrate

    through, or spend the winter in the

    Refuge. Their migrations take them to

    each of the 50 states, and they cross

    great oceans and follow distant

    coastlines to reach the lands and

    waters of six continents. Keeping this

    Refuge intact is critical for the

    survival of these birds. The Refuge

    also provides important habitat for

    the Porcupine Caribou Herd, polar

    bears, musk ox, wolves, grizzly bearsand other wildlife.

    It comes as no surprise that pro-

    drilling special interests are using

    their political influence and power to

    pressure Conference Committee

    members to open the Refuge to

    drilling. They erroneously claim that

    opening the Refuge to oil drilling will

    help reduce our reliance on oil from

    the Middle East, while others are

    using the possible war with Iraq to

    heighten the pro-drilling rhetoric.

    These claims are baseless. Here are

    the facts:

    Experts agree that drilling for oil in the

    Arctic Refuge will do little or nothing

    to reduce US dependence on foreign

    oil, nor will it address Americas long-

    term energy needs. There is only a 6-

    month supply of oil, and even oil

    industry officials admit that oilwouldnt be available for 10 years.

    Even with the most optimistic

    estimates of Arctic Refuge oil added

    to the oil fields off our coasts and

    everywhere else in the US, we still

    have only 3 to 4% of the worlds oil

    reserves.

    Bird nests are not bird homes.Nests are cradles, nothing more...Ilike to think of them as maternitywards.

    When birds sit on eggs, they arenot simply relaxing. They areregulating the temperature of theclutch. If too hot, the parent bird

    may need to cool the eggs byshading or moistening them. Somebirds make frequent trips to bird-baths or watering places to soaktheir belly feathers, then return tothe nest to cool the eggs. Somespecies cool the eggs by wavingtheir wings.

    Keeping the eggs warm maybe a challenge for early springnesters. April can be cool andwet and parent birds must siton the eggs for long periods oftime, without food or water.

    According to BirdscopeNews and Views from SapsuckerWoods of Cornell Lab of Orni-thology, ambient temperaturesmay also play a role in deter-

    mining the clutch size anddetermining how hard birdsmust work to keep the eggs atproper temperature.

    Mourning Doves, Zenaidamacoura, must be architecturallychallenged for their nest con-struction leaves much to bedesired. A pair built theirflimsy nest above our patio andthe eggs could be seen frombelow. The first little breeze

    blew the cradle right off thelimb. Their second nest sur-vived and hatched three babiesthat promptly fell out on to theground. I put them in densebrush nearby and hoped theparent birds would come totheir rescue. Although poornesters, Doves prosper and seemto grow in number each year.

    Someone brought me the

    nest of a Blue-gray Gnatcatcher,Polioptila caurela, and it is awork of art. Not only is itlovely to look at, it is sturdy andglued to the limb on which itsat. This work of a mastercraftsman (or craftsbird, if youwill) was saddled to a smallhorizontal branch of a water

    oak, and built of plant down,fiber, oak catkins; bound togetherwith insect silk, spider web andcovered with bits of lichen andplant down.

    Last year a Carolina Wren,Thoryothorus ludovicianus, raised itsbrood behind the shampoo in ouroutdoor shower. After the nest-lings had fledged I removed thenest and saw that its interior was

    white as snow. Upon furtherexamination I saw that the cleverwren had lined its cradle with finewhite fur from our cat that wasbrushed daily. The wads of fur fellonto the grass where the wrenretrieved and made good use of it.

    I always put lint from thedryer outside on twigs for easy useof Northern Mockingbirds,Mimus polyglottos. Once a Mock-ingbird was seen pulling strings

    from a dirty mop!Peterson Field Guides Eastern

    Birds Nests is a good source forlearning more about nests andnesting habits.

    Bird TreatyTakes Wing

    From Houston Chronicle Dina Cappiello

    For migrating birds, cities can

    be a deadly pit stop. Mirroredskyscrapers create the illusion of anendless sky to the wary travelersthen, whack. Telephone wires andelectrical lines can catch even theswiftest of wings and the landingstrip of manicured lawns isnothing more than giant dinnerplates for hungry cats.

    But the trip might be eased abit for the millions of birds that

    pass through Houston each season.In an agreement signed this fallbetween the city and the U.S. Fishand Wildlife Service, Houstonbecame the fourth metropolis inthe country to agree to activelyprotect migratory birds. Nationaland local dignitaries will officiallyannounce the signing early nextyear. Under the two-year pact,known as an Urban ConservationTreaty for Migratory Birds, several

    local educational and environmen-tal groups will match $160,000 infederal and corporate dollars toprovide more bird-friendly habitatand better monitor annual migra-tions.

    Houston is in a strategicallyvery important location. Anythingwe do good for birds here benefitsliterally all of North America,said Peter Stangel, regional directorfor the National Fish and WildlifeFoundation. The nonprofit, afunding arm of the service, do-nated $80,000 to the treaty. Halfof that money was donated byHouston-based Conoco Phillips,an oil and gas company.

    When it comes to bird traffic,Houston is a major rest stop on a

    superhighway running from Centraland Latin America to the Artic.Each year millions of neotropicalbirds, geese and other waterfowl,representing hundreds of species,pass through the area en route towarmer weather as the seasons

    change. Some stay and nest here,others just pause for refueling.

    While some of the projects inthe new treaty could potentially luremore birds to the areaby plantingvegetation in a number of local parksand building bird houses andfeedersothers will enhance re-searchers understanding of themigration.

    The projects will be done by August 2004 and include:

    Installation of 20 microphoneson schools and telephone companybuildings to record migratory birdcalls at night and to count popula-tions.

    Replacement of invasive specieswith native shrubs and trees in LittleThicket, Hermann, Memorial, andE.R. and Ann Taylor Parks.

    Development of educationalmaterials.

    Construction of an interpreta-tive trail and bird houses and feedersalong the White Oak Bayou.

    The scope of these projects willadd to the quality of life here inHouston, said Roksan Okan-Vick,director of the citys Parks andRecreation Department, which ismatching the $80,000 provided bythe federal government largelythrough in-kind services.

    Like many major cities,

    Houstons bird habitat has slowlybeen eaten away by developmentand sprawl. The native plants thatbirds have adapted to for shelter andfood have been taken over by exoticshrubs. Domestic animalsmostnotably the cathave become birdpredators. And pesticides and

    diseases such as West Nile virushave taken serious tolls on avianpopulations.

    Of the 836 migratory speciesprotected under federal law, wildlifeexperts estimate one-quarter to bein trouble. Of these, 78 are

    endangered and 14 are listed asthreatened on the federal endan-gered species list. More than 250species pass through Houston eachyear, according to the estimates.We sit in a place where the birdshave been coming through foreons, said Ron Jones, a wildlifebiologist with the U.S. Fish and Wildlife Service in Houston.

    One of the groups that appliedfor funding wants to use the moneyfor research. The South TexasChapter of the Telephone Pioneersof America, a group of Southwest-ern Bell Co. employees and retirees,plans to erect microphones onbuildings around the city to recordthe calls of migrant birds at night.The recordings will be fed into acomputer to determine the speciesfrom the sound. For some years,we have only been doing radar

    tracking at night, said GaryWoods, a member of the group.That only tells us the approximatenumber of birds, it tells us nothingabout the species.

    New Orleans, Chicago andPhiladelphia are the other threecities that signed treaties since theproject began in 1999. Portland isexpected to endorse a treaty inspring 2003. And four other citieshave applied, said Julie St. Louis,

    national coordinator for the pro-gram. In Chicago, one of theinitiatives called for dimmingdisorienting lights on skyscrapers.(Houston will not follow suit).The program is flexible, St. Louissaid. We expect the number ofcities to increase.

    The Ivory-billed Woodpecker(Campephilus principalis

    principalis) is or was one of therarest and largest woodpeckers inthe world. The genus comes fromthe combination of two Greekwords campa (a caterpillar) andphilos (loving). The species nameis Latin meaning principal,referring to the earlier belief thatcaterpillars were the primary foodof this species.

    Adults are about 20 inches inlength, mostly black, with a red

    crest on the male. The female hasno red on the head. A large whitestripe runs from behind the eyeand down the neck on both sidesof the head. When the bird is atrest, large white patches arevisible near the ends of the wings.While it is flying, white is visible

    on both the upper and lowerportions of the inner flight

    feathers. The bill is an ivorycolor.Its former range was in the

    southeastern United States,including all of the Southeastnorth of southeastern NorthCarolina, west to Missouri, andsouthwest through Oklahomaand Texas. The subspecies inCuba is Campephilus principalisbairdi.

    The habitat where this

    species once occurred was matureold-growth forest and cypressswamps. Its diet consistedmostly of wood-boring insectssuch as beetle larvae, but it alsoate other insects, fruits and seeds.It is or was the only woodpeckerin the United States able to pryunloosened bark off trees. Itmore commonly fed on insects intrees that had recently died, ordying portions of live trees.

    The known breeding oc-curred from January to April andrequired snags in mature old-growth forest for nesting. Nestsranged from 15 to 70 feet inheight and the female laid fromtwo to five glossy white eggs.Both adults incubated for ap-proximately 20 days. The maleincubated at night and the femaleincubated during the day. The

    young fledged within 35 days ofhatching. The male did most ofthe brooding and nest sanitation.A breeding pair required aboutthree square miles of forest.

    According to the U.S. Fishand Wildlife Service, the speciesis thought to be extirpated fromthe wild in North America.

    Remembering the Ivory-billed Woodpeckerby John Borom

    However, it has not been officiallydeclared extinct. The story of the

    Ivory-billed Woodpecker is a vividsymbol of a conservation failure of20th Century America.

    By 1900, millions of acres ofvirgin pine, cypress and hardwoodstill existed in the Southeast. Fora variety of reasons, those who hadopportunities to do so failed tosave even a single tract of thisprimary forest. A severe popula-tion decline occurred between1885 and 1900, along with

    logging activity. Hunting bycollectors for museums hastenedthe decline of the species.

    The last confirmed sighting ofan Ivory-billed Woodpecker in Alabama was in 1907. By 1938,the U.S. population had beenreduced to only about 22 indi-viduals. Despite the National Audubon Societys suggestionsthat the Singer Preserve in Louisi-ana be selectively logged, leavingold trees for woodpeckers, the lastgreat virgin bottomland swamp onthe whole North Americancontinent was logged out in 1943.One tree that was felled containedan Ivory-billed Woodpecker nestand eggs. A lone female lingeredabout that year.

    The last confirmed sighting inFlorida was in the ApalachicolaSwamp in 1950. However, an

    unconfirmed sighting of a bird inGulf Hammock was reported in1963. In 1961 and 1963 uncon-firmed reports came from theSantee Swamp in South Carolina.The last confirmed sightings inTexas were in Big Thicket in1960, 1961 and 1966. In Cuba,mixed hardwood forests were

    7/12

    7

    slashed away not only for lumberbut also to make way for the sugarindustry. The last confirmedsighting was in Cuba in 1987.

    Since then, there have beenunconfirmed reports that theIvory-billed Woodpecker has been

    seen or heard in the U.S. In1999, a LSU forestry studentreported that he had seen a pair inthe 35,000- acre Pearl River Wildlife Management Area whileturkey hunting in April. Hisperfectly described sighting led torenewed efforts to find the species,including a series of cooperativeexpeditions conducted by theCornell Laboratory of Ornithol-ogy, Zeiss Sports Optics, theLouisiana Natural HeritageProgram, Department of Wildlifeand Fisheries and the LSU Mu-

    seum of Natural Science.From late January through

    mid-March, 2002, acousticrecording units (ARUs), devel-oped by the Cornell Labs team ofbioacoustics engineers, recordedsounds, natural and otherwise,

    from 12 different positionsthroughout the forests of thePearl River drainage. The ARUshad been deployed by researchersfollowing rugged hikes throughbayous, brambles, and mud.Analysis of more than 4,000hours of digital data have shownno indication of the speciespresence.

    At one point, two differentresearch teams independentlyheard loud double raps thatsounded suspiciously like the

    distinctive display drum of thegenus Campephilus. Sadly,analysis proved that the soundswere distant gun shots that onlysounded to human ears likedrumming on a hollow snag.Researchers do not consider the

    results of this winters work to beconclusive as to the presence orabsence of the species in the PearlRiver forests and investigationswill continue.

    The real importance of savingsuch things as Ivory-billed Wood-peckers is not so much that weneed them as that we need to savethem. It is time we recognize where the threat comes from: notfrom our enemies but fromourselves.

    The Highlandsof Scotland

    We are indeed fortunate thatTom Sterling will be with us

    again during Film Week, January13-17. During this week, Tomwill be showing the film, TheHighlands of Scotland, tostudents in 10 public and privateschools. He will also show thefilm Monday, January 13 at theGovernment Street BaptistChurch and Thursday, January16 at 7:30 pm at FaulknerCommunity College.

    Tom has taken a fresh look atan old and revered land. Thecasual visitor tends to see neatand tidy coastal villages, the largecities of Edinburgh, Glasgow andInverness; castles, bagpipes andthousands of sheep. Well see allof this and much, much more.

    As a trained field naturalist,Tom takes us to the wilder partsof Scotlandthe highlands. Herewell see the beautiful Loch Ness,visit Hadrians Wall, watch asheep dog trial, visit a weaver, apottery and Balmorals Castle, theroyal familys autumn residence.When we visit the HighlandWildlife Park, Scotlands onlydrive-through wild animal park, well see red deer, arctic fox andmuch more.

    The fact that hundreds ofmillions of tiny neotropical (New World) songbirds, many weighing

    no more than a few pennies each,make a grueling journey betweentwo continents twice a year is oneof natures greatest marvels. Theurge to fly north in spring andsouth in fall is most likely trig-gered by changing day lengths.For weeks before they depart, thesongbirds gorge on food, buildingup fat reserves for the demandingflight. Some warblers may get200 miles of flying at peakefficiency from stored energy inone gram of fat.

    They leave Mexico, LatinAmerica and the Caribbean afterthe sun sets, fly at night whentemperatures are cooler andpredators are not as prevalent, andcontinue up to 20 hours nonstopover more than 600 miles of theGulf. They navigate using thelocation of the setting sun, the

    moon and other natural light, thepattern of the stars, topographicfeatures, and the Earths geomag-netic field. That such tiny livingfluffs of colorful feathers can travelsuch great distances against manyodds is among the reasons humansare so entranced by wild song-birds.

    Their goal is to make a reststop in the first line of extensiveforest on the mainland, perhaps

    20 to 30 miles inland. Untoldnumbers never make it that far.Some simply run out of fuel fromfighting head winds, and they fallinto the Gulf. Others maystruggle until they see the firstsliver of land along the coastwhere there is any woodland andsimply plop down.

    Songbird Challengesby John Borom

    The millions of songbirds thatdo continue their journey rest for aday or so, and consume hordes ofinsects, spiders, and fruits andseeds to rebuild their fat. Then,flying only at night, they make aseries of four to six hour flights,each spanning 50 miles or so.

    These flights are punctuated bystopovers that last from a few hoursto a few days.

    As the songbirds move north-ward, they often follow rivercorridors, where dense foliage offersprotection against daytime preda-tors and abundant food. Manychoose Alabama for their nestingplace. Others will fly as far northas the Canadian tundra to nest.Stopover areas are vitally importantfor migrating songbirds. Unfortu-nately, they are disappearing atalarming rates.

    Coastal wild places vital tosongbirds are now prime realestate. Critical habitat is givingway to vacation resorts, malls,houses and other development.

    Other resting stopsforests,grasslands, old fields and pitcherplant bogs have become parti-

    tioned by development into smallplots, places where predators are amajor menace.

    Fragmentation can bedevastating to songbirds. Studyafter study shows that the birdshave trouble raising their youngin small blocks of woods sur-rounded by clear cuts, farmlandand suburbs, as compared withlarge forest tracts. Fragmentationcreates places where predators

    such as house cats, snakes,raccoons and opossums arevirtually funneled into nestingsites.

    The U.S. EnvironmentalProtection Agency estimates thatthere are more than 100 milliondomestic and feral cats nation- wide. Clawed or declawed, well-fed or hungry, bell or no bell, allcats that spend time outside will

    hunt and kill wildlife includingbirds. Nationwide the number ofsongbirds killed by cats is cer-tainly in the hundreds of mil-lions.

    Human-made structuresare an increasing hazard tomigratory songbirds. It isestimated that 100 million birdsare killed each year by collisionswith buildings and skyscrapers.Many millions more are killed by

    towers, such as those erected forcell phones. A study released bythe American Bird Conservancyreleased last summer says thegrim toll runs as high as 40million birds annually. Presently,there are over 1400 towers in Alabama. The number continues

    Weeks BayField Trip

    By Celeste Hinds

    Audubon member CindyMcDonald missed the boat, butshe was determined not to be leftbehind. She hailed a fishermanand begged a ride out to catch upwith the Estaurine Queen makingway out of Weeks Bay down tothe Magnolia River.

    It was a cool crisp morning onOctober 19 and we enjoyed a slowboat ride on smooth waters. EricBrunden was captain for the

    morning and Sarah Johnston wasfirst mate. Eric is ResearchTechnician at Weeks Bay Reserveand Sarahs position is GIS (geo-graphic information systems).

    The boat had a full comple-ment as we searched for water fowlalong the banks. Osprey were

    sighted, along with Cormorants,Laughing Gulls, Caspian Terns,Foresters Terns and Brown Peli-cans. Trees along the banks held a Yellow-Crowned Night Heron,Kingfisher, Red-Winged Black-birds and Red-Bellied Woodpeck-

    ers. Someone thought they saw aBald Eagle but I didnt see it.

    Although we did not find anabundance of birds we enjoyedthe water and the foliage. Seeingmailboxes where mail is deliveredby boat to homes along theMagnolia River was new to someof the passengers. It was fun toobserve the remote brackish areasalong the river and learn that afew very pristine areas still exist inbeautiful Baldwin County.

    Thanks to John Borom forarranging this trip. He wasotherwise engaged and but wemanaged to have a good timewithout him. Thanks to EricBrunden and Sarah Johnston forkeeping us safe.

    to increase. The more towers, themore dead birds. Other problemsconfronting migrating songbirdsinclude collisions with automo-biles, pollution and nest parasit-ism by Brown-headed Cowbirds.

    In the fall, they make

    their return trip to the tropics.From Mexico to Colombia, manysongbirds winter in coffee planta-tions, where coffee bushes havetraditionally been grown under ashady canopy of native forest trees.Unfortunately, this habitat isdisappearing as plantationsintensify and replant with higheryielding, sun-tolerant coffeevarieties that do not require shade.The result is that songbirds mustsearch even harder to find suitablewintering territory.

    In recent years, spring hasgrown noticeably quieter and fallskies more still. Dozens ofAlabamas most colorful, sweet-sounding songbirds are in serioustrouble.
