Keynote Address by
Dr. H. Ronald Pulliam

Talk Title:
“On the diversity, coexistence and conservation of grassland sparrows”

Dr. Pulliam’s talk will weave the AOS 2018 meeting theme together with perspectives from ecological theory, empirical field studies, and the pressing conservation issues of our time. He has published over 150 scientific articles and books on a wide range of topics including niche theory, animal foraging and flocking behavior, source sink dynamics, and the ecology of grassland birds. His work on sparrows in southeastern Arizona has spanned several decades.

Southeastern Arizona has long attracted birders and ornithologists wishing to observe, document, and study Mexican species that just barely make it across the border of the United States into this unique region. The groundbreaking 1979 book, Birds in Southeastern Arizona, written by William A. Davis and Stephen M. Russell and published by Tucson Audubon Society, was the first regional guide to finding these species.  In the nearly 40 intervening years, birders, citizen scientists, and ornithologists have collected a treasure trove of new information on bird records, distribution, life history, range expansions and contractions.  As birding has become increasingly popular, so too, have the resources on when and where to find birds in Southeastern Arizona.  Symposium attendees will not only enjoy photos of this region’s most beautiful and sought-after birds, but will also learn about: range extensions of such rarities as Short-tailed Hawk, Flame-colored Tanager, and Slate-throated Redstart; changes in grassland bird habitat and associated bird species; Citizen Science survey results of Elegant Trogon distribution; hummingbird distributions in southeastern Arizona with estimates of how long they live; and an update on the northernmost Cactus Ferruginous Pygmy-owls in North America.
