Welcome to the Avian Ecology & Behavior Lab

 

Our research is broadly focused on the links between ecology, evolution, and behavior of year-round resident birds, using individual-based studies to understand variation in individual fitness and population demography. Our work examines reproductive and dispersal strategies, life history trade-offs, demography, and seed dispersal and how the changing environment impacts these processes. Lab projects include: impacts of rainfall and fragmentation on demography in understory birds in Panama, causes of variation in fitness and demography of birds in central Panama, the role of invasive vertebrates in seed dispersal in Hawaii, and life histories and demography of song sparrows in British Columbia. These projects are aimed at understanding how linkages between individual, population, and community scales are impacted by environmental changes.

Sam is back in Hawaii gearing up for another great field season studying gamebirds!

December 03, 2018

Long-term crew leader, Laura Gomez-Murillo, has decided to join the Tarwater lab in January as a MSc student. We are excited to have her!

November 15, 2018

Laura Gomez-Murillo received a fellowship to become a STRI intern for Feb - April 2019. Congrats Laura! She will be working on a project in antshrikes looking at aggression across the rainfall-fragmentation gradient.

August 21, 2018

Corey became a Smithsonian Tropical Research Institute Research Associate

Our article on impacts of early conditions on LRS just came out in the Auk 135:609-621:

Examination of context-dependent effects of natal traits on lifetime reproductive success using a long-term study of a temperate songbird - Corey E. Tarwater, Ryan R. Germain and Peter Arcese

May 11, 2018

Corey took over the long-term netting this year in Panama and it was a great success! We added molting and aging metrics with the help of crew leader Laura. We captured 253 birds of 42 species over a 6 day period. We were able to classify many species into fledgling, juvenile (1st year), and adult. It is very exciting to add this new component to the long-term netting!

May 09, 2018

Congratulations to undergrads Rosemary and Josephine! They were just accepted into the Wyoming Research Scholars Program! This means they get paid to do their own independent research and be part of an amazing research program! Rosemary will be studying factors influencing frugivory rates in Hawaii and Josephine will be studying manakin vocalizations in Panama.
