This presentation will review recent results from Hawk Mountain Sanctuary's research program. The audience will witness how they manage to monitor these highly mobile and unpredictable predatory birds throughout consecutive years via a slide show depicting field work situations. JF Therrien grew up in Sherbrooke, Canada, about 30 minutes from the border with Vermont. He […]
More than half of the World’s species of diurnal raptors perform annual migrations, especially those populations in higher northern and southern latitudes. However, the entire population migrates in only a few species. Beginning with North America, Bill Clark will show photographs of and discuss some of the locations on five continents where people regularly gather […]
March 2023 Lunch & Learn Presentation Series Mike Stewart is a Texas A&M PhD student studying Gray Hawks. He will be joining us to discuss his Masters research which will be featured in the upcoming issue of Journal of Raptor Research. For his studies, he used GPS-GSM telemetry to quantify dispersal time and distance, winter […]
American Bird Conservancy’s Pesticides and Birds Campaign is dedicated to reducing threats to birds from toxic pesticides and lead, particularly from rodenticides and ammunition. Policy may not seem like the most exciting area, but new studies from scientists, new emphasis from the EPA, and bold statements from the US Fish and Wildlife Service promise to […]
Scott Harris spent 16 months, chasing 55 Raptors across 34 states—his version of a Raptor Big Year. Scott is going to share about his adventures, misadventures, successes and failures. From -36 degree days, to ones over 100 degrees, to just getting on the bird in time, to the frustrations of missing one by minutes. It’s […]
In 2014 Hawk Mountain Sanctuary launched a full annual cycle study of the Broad-winged Hawk. Almost a decade later, Sanctuary biologists are continuing to uncover the mysteries of this long-distance migrant. Rebecca McCabe will provide an update on the project with a focus on movement data from telemetry-tracked broad-winged hawks. Rebecca received her B.S. in […]
The Hook-billed Kite (Chondrohierax uncinatus) is a highly specialized, snail eating Neotropical raptor with a wide distribution that has received little research attention despite local declines occurring. It was once considered to be non-migratory, but Ryan and his team have documented a significant (5,000-9,000) migration of Hook-billed Kites in Belize and have studied this migration […]
John and Eugene Jacobs are attempting to determine the breeding range, nest site fidelity, breeding habitat use, migration timing and routes, wintering areas and wintering habitat used by Red-shouldered Hawks (Buteo lineatus) that breed in Wisconsin. Join us for another in the series of Lunch & Learns where we welcome John Jacobs to share about […]
Join us for another in the series of Lunch & Learns where we welcome John Jacobs to share about his Red-shouldered Hawk telemetry research. John and his brother, Eugene Jacobs are attempting to determine the breeding range, nest site fidelity, breeding habitat use, migration timing and routes, wintering areas and wintering habitat used by Red-shouldered […]
Join us for another in our Lunch & Learn series as we welcome back Esther Viviana Vallejo Santamaria who will present the most recent information about the threat of illegal hunting that still persists to migrating raptors in Colombia. These birds play a vital role in our ecosystems, and yet, their very existence is jeopardized […]
