Abstract
The species that participated in mixed-species foraging flocks in the pine-oak woodlands of western Mexico differed significantly in their foraging microhabitats (plant species and locations within the plants) and foraging movement patterns (average number of moves s-1 and average length of a given move). Because the foraging locations and rates of progression while feeding within trees differed among species, some species must be making continual adjustments to match the overall rate of flock progression. These same species may be buying the benefits of flocking at a cost in terms of feeding efficiency.This publication has 20 references indexed in Scilit:
