Field work in Puerto Rico

The lab spent May and June studying Adelaide's warblers at the Cabo Rojo National Wildlife Refuge in Puerto Rico. We caught a lot of birds, bringing our total to 76 color-banded individuals. We also acquired DNA samples, developed color measurement protocols, found nests, and mapped territories. With the help of our excellent field assistants, Orlando Medina and Luis Rodriguez, and a bunch of great volunteers from the University of Puerto Rico, we recorded long bouts of morning singing from 45 of our banded males. With this large pool of color-banded, recorded individuals, the lab is well-positioned to hit the ground running with playback experiments in the Spring of 2017.
