Bird Sketches by Diane Pierce

This is the first I’ve become aware of Diane Pierce and her artwork, but I think her pencil sketches of birds are incredible. The following brief biographical sketch of Ms. Pierce is from the Acknowledgments section of the Florida's Breeding Bird Atlas:

The Florida BBA project was indeed fortunate to secure the artistic talents of Diane Pierce . . . Ms. Pierce's artwork has appeared in many scientific journals and popular magazines, and in numerous books including National Geographic Field Guide to the Birds of North America, So Cranes May Dance, An Introduction to Ornithology, Endangered Birds, and the 1996 edition of A Birder's Guide to Florida.
