We're tossing it up today at SciArt of the Day to offer a plate from the ubiquitous Peterson Field Guides to birds of the world. Keep an eye out later this afternoon for a more detailed post on an auction of 500 original paintings and 200 wildlife photographs by Peterson being held this week in New York.

For now, enjoy "Cuckoos, Nightjars, Pootoos" by Roger Tory Peterson; Gouache, watercolor, pencil and ink on board with overlay.

From Field Guide to Mexican Birds and Adjacent Central America, 1973.
