(NOTE: The first three paragraphs of this report were intended
to accompany the photographs in the September issue of Valley Habitat.)
MERCED COUNTY: On May 18, Peter Metropolous had a “LEAST” BELL’S VIREO singing on the Souza Trail atthe San Luis National Wildlife Refuge. Shortly thereafter, another birder reported a second singing Bell’s Vireo. Thatis the same location where two Bell’s Vireos were found last spring, so they might be the same birds returning. Since
this vireo is a state endangered species, its return to the Central Valley is always encouraging news.
STANISLAUS COUNTY: On May 23, Joe Devine and his grandson Caleb had three BLACK TERNS overHawkins Pond. This tern is very social, and may migrate in flocks of thousands. Ralph Baker had a YELLOW-BREASTED CHAT on June 19 at the San Joaquin River N.W.R. This odd bird, which sounds like a thrasher, is placedin the Wood-Warbler family. The chat bears a resemblance, however, to tanagers, yet its scientific name is Icteria vi-
rens, which suggests an oriole, so its placement is an ongoing anomaly.
Daniel Gilman and Sal Salerno found a COMMON POORWILL in Del Puerto Canyon on the evening of July
1. John Harris and Sal Salerno had three LESSER NIGHTHAWKS flying over a pond on Willms Road on July 5.These birds were called goatsuckers because of the folktale claiming that they’d suckle on goats at night. The truth is,
these aerial acrobats forage for insects from dusk to dawn.
MERCED COUNTY: On September 5, Ken van Vuren had a BAIRD’S SANDPIPER near Gustine. The mi-gration route of these birds is usually through the Great Plains. In the spring, they may travel 9,300 miles from the Arc-
tic to Southern America in only five weeks.
STANISLAUS COUNTY: On September 11, Eric Caine had a first-summer COMMON TERN (not pictured)at the restricted-access Modesto Water Quality Control Facility. This tern drinks water on the wing, dipping its bill in
the water as it glides; those living on the coast drink sea water.
Any layman birder like mewho attempts to explore that question
must be prepared to suffer the slingsand arrows of outraged ornithol-ogists. Even many biologists andfellow birders may shake their headsand mutter over this page. But when Irecall that my readership is com- prised mostly of generalists, and thatmy purpose is to stimulate interest in
birds, those facts should be armor enough.
The definition of any species,not only birds, is a highly chargedissue. John Wilkins has written,
with nearly as much truth as wit,that there are “n+1 definitions ofspecies in a room of n biologists.”To simplify their contentious de- bates, I’ll point to their two major
explanations.
In 1942, Ernest Mayroutlined the Biological SpeciesConcept. The BSC defined a spe-cies as “a group of interbreedingnatural populations that are re-
productively isolated from othersuch groups.” That key term,“reproductive isolation,” means thattwo different species cannot success-fully produce offspring that can re-
produce themselves.
The BSC is elegant in itssimplicity, yes? But birds will be birds, and we know of many specieshybridizing in nature, notably amonggeese, ducks, and gulls. One estimatehas it that 10% of species have pro-
duced hybrids. If we strictly adhereto the BSC, that would require“lumping” of distinctly different birds. Bullock’s and Baltimore Ori-oles, as one of numerous examples,were once lumped as a single species because their hybrid offspring are
fertile.
In 1980, an alternative to theBSC was proposed. The Phylogenetic
Species Concept defines a species as“the smallest aggregation of popula-tions or lineages diagnosable by a
unique combination of character
states.” This definition can usemany markers to determine how onegroup of birds is recognizably differ-ent from other closely related birds.The DNA sequencing techniques thathave developed over the past thirty years
have given the proponents of the PSC
more clinical tools for identifying species.
The PSC is right for the mod-ern age, yes? But once again, natureintroduces difficulties by producingsubspecies of birds. A subspecies(also called “race”) shows variationin appearance from the main speciesdue to geographical isolation. Thesevariations in size, plumage patterns,and even vocalizations can be subtle
over their ranges. Look in your fieldguide at Dark-eyed Junco, and you’llsee six races of the same species.Kenn Kaufman has stated that overone-third of all North American spe-cies has some geographical variation.If we adhere strictly to the PSC, its proponents have claimed, the number
of bird species may double!
The American Ornithol-ogists’ Union (AOU) is responsible
for the classification of North andMiddle American bird species. Alt-hough the birds themselves havehardly changed in recent decades,their scientific and common namesare in constant flux: the AOU Check-list of North American Birds is nowin its 52nd supplement. Its Classifica-tion Committee had been “lumping”similar birds into the same species,
but recently the trend has movedinto “splitting” previously consid-
ered subspecies into separate spe-cies.
Although the AOU stillswears by the BSC, its actual practice has adopted some of themethods of the PSC. Recentsplits include Mexican Whip- poor-will from Eastern Whip- poor-will, as well as the PacificWren from Winter Wren. Birderscall that an “armchair tick,”meaning that they can comforta-
bly add a new species to their listwithout having to chase after it. TheWestern Scrub-Jay you see in your backyard is subtly different from theone you saw during your last trip tothe coast, and the AOU may be split-ting those races into separate species
someday.
Humans have a compulsiveneed to categorize experience in or-der to know the world. Nature, in itsinfinite diversity, is continually re-sisting such categories and absoluteknowledge. I’ve only skimmed thesurface of a fathomless well here.How many species of birds are there?
Stay tuned. The answer to the ques-tion proposed in the title above mayhave to be summarized not by words,

We birded several Stanislaus River parks this morning,
focusing on pure migrants. We got two Willow Fly-
catchers, several Yellow Warblers, and a quick view at a
Wilson's Warbler. Also of note was a Lincoln's Sparrowwhich is not supposed to migrate back into this area
until mid-September and a Cooper's Hawk which
was soaring like a Red Tailed over Horseshoe
Lake, instead of waiting quietly in a tree for the

MONTHLY BIRDWATCHING TRIPS TO THE SAN JOAQUIN RIVER NATIONAL WILDLIFE REFUGE
Stanislaus Audubon Society organizes a bird watching field trip each month to the San JoaquinRiver N.W.R. The next trip will be on Sunday, October 16. We will meet in the parking lot behind theStanislaus County Library, 15th and H Streets, Modesto at 7:00 a.m. Starting this year, we will be doingthese trips on the third Sunday of each month, except November and December. In November, we will goon the fourth Sunday, which is November 27. The permit that has been issued to Stanislaus Audubon So-
ciety slows us to visit most of the closed portion of the refuge on our field trips. Hope to see you there!
And, of course, our Sierra Club hasan excellent approach: 1.) Recognize that
increased population is unsustainable andconnected to many of the world's most seri-ous problems. 2.) Promote voluntary fami-ly planning and realistic sex educationaround the world and in the U.S. (The U.S.has the highest teenage pregnancy rate ofany developed nation.) 3.) Advance eco-nomic and educational opportunities forwomen and girls especially in developingnations where birth rates are much higher.4.) Curb our ecological footprint. And
there's plenty more at sierraclub.org. So look, the English scholar Thomas
Malthus warned us about population problemstwo hundred years ago. But you don't need tostudy Malthusian growth models to knowwhich way the wind blows. There's too damn
