Data associated with Riehl and Smart, 2022. Climate fluctuations maintain variation in group size in a cooperative bird; Current Biology. Field data were collected from a wild population of greater anis (Crotophaga major) in the Barro Colorado Nature Monument, central Panama, from 2007-2019. Nests were monitored to quantify individual reproductive output (number of eggs, nestlings, and fledglings produced) for females in communal groups, and individual reproductive success was correlated with a climate metric, the Southern Oscillation Index, to examine how climate affected the fitness costs and benefits of group size. All protocols were approved by the IACUC of the Smithsonian Tropical Research Institute and samples were exported from Panama and imported to the U.S. with permissions from ANAM and MiAmbiente (Panama) and the U.S.D.A. and the U.S. Fish and Wildlife Service (U.S.).
