Hear Rebecca's talk, now archived
online! Historically a bird of the countryside, the American Crow has moved into cities only in the last 20 years. For this they may be paying a price. Although crows are skilled at finding foods in city trash cans and compost piles, the nutritive value of most of what they find in these areas is low. Rebecca will reveal the developmental repercussions for nestling crows raised on the city “junk food” diet. |

Environmental and Social Determinants of Behavioral Variability: Examples from Western Bluebirds Janis Dickinson, director of Citizen Science, Cornell Lab of Ornithology |
|
| Hear Janis's talk, now archived
online! During the course of their lives, animals face a series of behavioral choices that can have important consequences for survival and reproduction. Nowhere is this more evident than in the complex social lives of Western Bluebirds. Janis will describe the rules male Western Bluebirds use to make decisions about dispersal and reproduction, based on a 20+ year study in central coastal California. |

|
| Hear Jack's talk, now archived
online! Burrowing Owls, while numerically abundant, are a Species of Special Concern in California due to declining population trends and the disappearance of nesting owls in many areas. Jack will describe the challenges of Burrowing Owl conservation in California and the long-term management of a Burrowing Owl colony at San Jose International Airport that seems to be beating the odds. His seminar gives special emphasis to understanding the basic biology and natural history of this charismatic species, as well as the conflicts that arise when managing Burrowing Owls at a major airport. |

Observing and Portraying the Harpy Eagle and its Habitat David N. Kitler, artist, Worldwide Nature Artists Group (WNAG) |
|
| Hear David's talk, now archived
online! The Harpy Eagle is one of the most powerful birds of prey in the world. Although it once ranged from Mexico to Argentina, it has disappeared almost entirely due to hunting and loss of habitat. During this presentation you will have the opportunity to accompany nature and wildlife artist David N. Kitler to the jungles of Panama. There, in the first-ever WNAG Flag Expedition, he observed and gathered reference material on this amazing raptor and its habitat. The images created as a result of the expedition will be used to increase public awareness on the key role this species plays in the maintenance of a healthy ecosystem. |

Foraging Effort and Diving Behavior of Double-crested Cormorants at Three New York Colonies Jeremy Coleman, doctoral candidate,NY Cooperative Research Unit, Department of Natural Resources, Cornell University |
|
| Hear Jeremy's talk, now archived
online! Cormorants have long been known for their foraging prowess but their reputation as insatiable fish predators has often been exaggerated. Jeremy will discuss general cormorant foraging behavior gleaned during his research on breeding Double-crested Cormorants from colonies on Oneida Lake, Lake Ontario, and Lake Champlain. He will also describe previously unknown details about cormorants in their underwater world that were gathered using innovative electronic time-depth recorders. |
