I Spoke Too Soon

Posted by: Rick Wright | Comments (0)

I am nothing if not a considerate spouse. Alison had been home nearly 13 hours before I even suggested heading to a sewage pond.

Alison is nothing if not an indulgent spouse.

We arrived at the Benson sewage ponds at 1:00, to find Denis and Kt willing the bird not to fly. And it worked: an adult Tundra Swan in all its ice-white glory, floating sleepily on the southern pond. State bird, yearbird, and this time truly, really, actually the last of 2006 for me.

Tail End of the Year

Posted by: Rick Wright | Comments (1)

It wasn’t meant to be a quiz, but this is the only photo I managed to get this afternoon of the Worm-eating Warbler currently in residence along the Santa Cruz River at Tubac. A state bird for me, and almost certainly my last yearbird for 2006. 

Following her very pleasant Audubon walk on the David Yetman Trail, Darlene and I headed south to Tubac. The weather warmed up, the skies cleared, and birding was great. The Worm-eating Warbler appeared within the first 20 minutes, simply flying in, prospecting busily in a few clumps of cottonwood leaves, then continuing west and out of sight; it called 3 times, on landing and twice while it was foraging. The picture doesn’t, ahem, do the bird justice; that orange blush to the underparts and the brightly striped head always take my breath away.

Other highlights: a male Wilson’s Warbler, a stunningly beautiful little Sharp-shinned Hawk, handsome bright Orange-crowned Warblers, Lawrence’s Goldfinch, Ruby-crowned Kinglets doing their Lavinia act, and a pudgy Hutton’s Vireo wreaking havoc on the local caterpillar population.

Catalina State Park

Posted by: Rick Wright | Comments (0)

Birding Catalina this morning was a lot like wandering through a Chinese scroll.

Fog in the lowlands, snow on the mountains, and an uncharacteristic chill in the air!

But as always, there were birds to be seen. A Western Scrub-Jay greeted me as I pulled in to the park. An excellent thrush show included a flock of 7 Western Bluebirds and a surprise American Robin, a female perhaps driven down from her more usual mountain habitats by the weather.

Surprisingly, given the low overcast, raptors were good. A Peregrine Falcon flashed through a flock of Mourning Doves early on, to be followed a bit later by a Merlin, that latter a very rare sighting in the park. American Kestrels were finding prey, while a pair of Red-tailed Hawks was perched on the way out at the end of a very pleasant walk.

One could argue that birding in the western hemisphere started on Hispaniola, with the colorful birds captured by Columbus’s men as trophies of their voyage. Today, more than five centuries later, this Caribbean island and the two nations that share it, Haiti and the Dominican Republic, are the subject of renewed interest in the birding community; Hispaniola now has its own eBird (at http://www.ebird.org/Hispaniola/) and its own field guide, a handsome, easy-to-use volume available in English, Spanish, and French.

And just in time. No fewer than 38 of Hispaniola’s 306 avian species are endangered, among them fully 15 of the island’s 31 endemics. Habitat loss and degradation are to blame; the authors also cite failure to enforce environmental laws and a lack of local knowledge of the island’s biodiversity and its importance. The ultimate goal of Birds of the Dominican Republic and Haiti is to “inspire a new generation of birdwatchers, ornithologists, and conservationists” to “become as fascinated as we are by the diversity of the island’s avifauna.” The guide has a good chance to do just that.

BDRH adheres to the familiar format of color plates with facing-page identification notes, followed by a more expansive text offering a detailed description, distinctions from similar species, a voice description, detailed status and distribution information for Hispaniola, and miscellaneous comments. Each species account is accompanied by a range map, and local names (in Spanish for the Dominican Republic, in Creole and in French for Haiti) are also provided.

These longer texts are generally adequate for the identification of all but the most subtly distinguished species, and will likely serve both visitors to Hispaniola and local birders well. The “Comments” sections are often thorough, concise explorations of the more interesting aspects of a species’ life history or conservation status. Only occasionally do the species accounts leave important questions unanswered: we are told, for example, that the West Indian forms of the Short-eared Owl differ from North American birds ”in plumage and vocalizations,” but regrettably, no details are offered about those distinctions. The presentation of additional taxonomic information is generally clear and thorough, but the comment in the account for Hispaniolan Crossbill is befuddling: the authors write of “this crossbill” as “a species typical of northern coniferous forests,” and note that it was “considered part of the White-winged Crossbill species complex” until 2003. It would have been more accurate, and thus necessarily less confusing, to write that the Hispaniolan Crossbill was long considered conspecific with the White-winged Crossbill, but was recognized as a separate species in 2003.

The front of the book is rather less satisfying. The color plates (many borrowed from Princeton’s West Indies) range from adequate to poor. Hispaniolan endemics are depicted in full-page portraits by Barry Kent McKay; these images are dramatic and decorative, but particularly in the case of those species presenting identification challenges, a more traditional field-guide format, showing the birds against a plain background and in profile, might have been more helpful. Unfortunately, the tails and bills of some of McKay’s birds are cut off in my review copy.  

The telegraphic identification texts facing the plates are generally quite good. Occasionally, though, the text emphasizes a field mark not visible in the facing image; for example, the strong white primary fringing described for Stolid Flycatcher cannot be seen on the plate. (This problem is shared with the plate in Raffaele et al., where the text speaks of “primaries” but arrows point to the strong white fringing of the bird’s tertials.) Conversely, some images show features useful for identification that are not addressed in the text; the different face patterns of Tree and Golden Swallows, clearly depicted but unmentioned, are an example. The scale on many plates is off as well, making a Song Sparrow as long as a Rose-breasted Grosbeak.

Most troubling perhaps is the topography sketch in the field guide’s front matter. Not only is the drawing (of a Hispaniolan Spindalis) misshapen, but a number of the labels are incorrect: the “secondaries” are actually tertials, the “malar” actually the throat, the “legs” actually the tarsus (or tarsometatarsus, as long as I’m being picky), and the “chest”–well, I don’t know what that is. This is a disservice to the new and potential birders the guide hopes to attract, and should be corrected in any subsequent printings of the book.

The weakness of the illustrations, though, is far outweighed by the usefulness of the text, and by the value of the book as a whole. Let us hope that its goal is realized, and that the residents of Hispaniola come to recognize the beautiful diversity of their avifauna before it is too late.

Snow

Posted by: Rick Wright | Comments (0)

Our winter rains did in fact start yesterday evening, but at elevations only slightly higher than ours here in Tucson, the precipitation turned quickly to snow. Darlene and I drove through steady snow to Benson this morning, with the desert ground white around us. If you think Vermilion Flycatchers are beautiful, you should see them in the snow!

The Benson sewage ponds were quite active, with a dozen species of waterfowl including amorous Buffleheads and, appropriately enough, the continuing Snow Geese. Eared Grebes and American Coots floated around with clumps of snow on their backs (“hey, isn’t this what we came south to get away from?!?”), while Great Blue Herons, a Great Egret, and a Green Heron were hunting the golf course ponds, looking dour as the flakes fell around them.

Our biggest surprise was a cold-looking Barn Swallow, hunting low over the waters of the largest pond. It was a short-tailed, dull-plumaged bird, but seemed generally healthy enough for a Barn Swallow in the late-December snow.

And no, no swans….
