个人简介
I am an ornithologist with strong interests in physiological, evolutionary and behavioral ecology. My current work explores the causes of temporal and spatial variation in the life histories of birds, focusing mostly on breeding biology and movements. My abiding interest in the Charadriiformes was augmented starting in the mid-1980’s with detailed studies of life history variation in Tree Swallows (Tachycineta bicolor), and then all members of the genus throughout the Americas in a project we call Golondrinas de las Americas. With my students and collaborators, I have been studying everything about these birds that we can on the breeding grounds, from immunocompetence and telomere dynamics to flight performance and the composition of bacterial communities in their nests. We are interested in how changing climates and geographic variation in environments affect all aspects of the life histories of these birds, and in recent years, we are expanding our understanding of their life histories outside the breeding season, with studies of their diets, social behavior and movements. I lead a group of engineers and students that I call TABER (Technology for Animal Biology and Environmental Research), which has recently designed solar-powered radio-tags that are small enough (0.7 g) to place on swallows and can be expected to transmit whenever the sun shines for many years. These tags, and many more like them, are energizing our studies of animal movements, and will fuel our studies for years to come on migration and dispersal. The other area of technological innovation that has sparked my interest of late is the ready availability of high-acuity computed tomography (CT) scanning at Cornell, which has led me to work, with Helen James at the Smithsonian, toward a web site that features a video tour of the anatomy of a member of every family of birds around the world. This brings me back to my undergrad fascination with anatomy and combines it with my career-long dedication to the broadest view of the diversity of life, signified by the recent completion of Bird Families of the World (Lynx Edicions).
