摘要

The present study examined the temporal characteristics of the foraging move- ments of free-ranging Black-capped Chickadees (Poecile atricapillus) in a mixed-coniferous forest in central Maine to investigate how patterns of patch persistence in the wild compared with observations from controlled experiments. Persistence in trees, as measured by the amount of time from the last prey capture attempt in a tree until exit from that tree, was positively correlated with the average amount of time between capture attempts in those trees.
