There’s definite movement among the gulls of Vancouver this week. A California Gull was at Kitsilano Pool early this morning, and another adult was on the sewage ponds at Iona with three score Mew Gulls and 19 Thayer’s Gulls as the tide rose mid-day.

That taxon is named for John Eliot Thayer, who bankrolled the 1913 Alaska expedition that collected the first specimens. Maybe we’ll hear a little more more about him next year, the 150th anniversary of his birth–but I’ve been thinking about a different Thayer these past days.

You will have noticed all the attention being devoted to Richard Crossley’s impressive new ID Guide: for a month now, not a day has gone by without a glowing notice at one blog or another, and my own review seemed almost tardy when I “finally”–two days after receiving the book–posted it at the ABA blog.

Birders’ reactions so far (those reactions, that is to say, that have done more than just repeat the breathless jacket text) have concentrated on the guide’s plates, an entirely appropriate focus given the innovative nature of the illustrations in this book that so proudly “doesn’t like text.” And there have been some perceptive characterizations. Spencer, one of the most critically alert birders I know, has pointed out how the vitiation of perspective in the plates highlights the “constructedness” of identification texts, while several ‘bloggers’ have noticed that viewing these plates recalls the contemplation of Victorian dioramas. And not a few reviewers have compared Crossley’s photo montages to the work of Louis Agassiz Fuertes.

If all you know of Fuertes are the paintings in Pearson’s venerable Birds of America, then I suppose I can see it: there is a certain bustle to those images, particularly among the birds of prey, that anticipates in a distant way the cheek-to-jowl figures in Crossley’s plates. There is a faint stylistic echo, too, in the prominence with which the larger figures seize the foreground. But the source of each work’s pictorial density is very different: economic in the case of Birds of America, pedagogic in Crossley’s.

What many of the photographs in Crossley’s ID Guide do remind me of, and sometimes forcefully, is the work and the ideas of Abbott Thayer (no close relation, so far as I know, to John Eliot).

Look at Crossley’s owls, his grouse, his nightjars, his thrushes, and on and on, and you’ll find illustrations–literally–of the Thayerian principles of camouflage and obliteration almost as striking as the artist’s own.

By the time of his death in 1921, Thayer’s theory that all coloration was ultimately and exclusively disruptive was largely dismissed as overstated and inflexible, and his influence on natural history illustration remained negligible at best for nine decades.

Maybe that’s changed now.
