I am pleased and honored to be the recipient of a generous research award bestowed by the American Ornithologist's Union. The grant will fund an ambitious slate of field playback experiments to quantify population's behavioral responses (or lack thereof) to songs from related, allopatric populations. I will then use this data to measure rates of premating reproductive isolation in tropical birds. The concept for this line of inquiry comes from last year's Advanced Tropical Field Ornithology course. Students in this course completed a series of playback projects to measure how White-breasted Wood-Wrens respond to genetically divergent, allopatric populations, and recently published the results. Read the study here; a recap is here. Now we'll massively expand this project to include a whole raft of Costa Rican species. Thanks to the AOU for giving this exciting project a jumpstart!
