This new Lance-tailed Manakins towards the Isla Boca Brava was in fact monitored of the Emily DuVal and you will acquaintances because the 1999 within a lengthy-label study of cooperation and you will partner alternatives. Current look into the variability within the cooperative behavior are financed by the a beneficial Career honor on National Research Foundation (# 1453408). The present day project yields on the DuVal’s early in the day operate in so it population, which had been supported by the latest National Research Foundation; The latest Fl County College or university in the Tallahassee, FL; The new Max Planck Institute to possess Ornithology inside Seewiesen, Germany; this new College away from Ca on Berkeley, together with Federal Geographical Society’s Committee getting Search and you can Exploration.
