In spring 2009 I began working on a collaborative project with North Carolina State University and the Puerto Rican Department of Natural and Environmental Resources to understand forest bird communities in southwestern Puerto Rico. Amber Wiewel, a M.S. student in my lab, is trying to understand their breeding biology and relate nest survival and movements to availability of fruit.

Her research is conducted in Guánica State Forest, a dry forest located on the southwestern coast of Puerto Rico, and focuses on estimating nest and juvenile survival of bullfinches by monitoring nests and radio-tracking fledglings. She hopes to develop a productivity estimate from our n
