Diet and Foraging

Diet

The White-collared Swift is an aerial insectivore, catching and eating insects on the wing.

Stomach content studies of two specimens (one male, one female) collected in southern Mexico by Rowley and Orr (1965) found that the esophagus, crop and stomachs of the birds were filled with insect material. It was noted that the greatest majority of insects  eaten by the birds were flying ants.

The stomach of a bird that washed up on a beach in Texas was found to contain large numbers of Hippodamia convergens (Lasley 1984).
