Differences in parental care in birds have been mostly examined in species characterized by sexual dimorphism, and data is scarce regarding the roles of the two sexes in monomorphic birds. Differences between males and females in parental care may include bird movement, foraging, flight behavior, and food provisioning to the young. In this study, we examined the movement characteristics of the Little Swift (Apus affinis), a small (25 g) highly aerial and monomorphic species that breed in colonies. I explored the details of bird movement using an advanced tracking system in the Hula Valley of northeastern Israel and found differences between the sexes in movement and parental behavior during the breeding season. Specifically, nest residence time, foraging range, number of visits to the colony during the day, and the times of entry and exit to the colony, as well as nocturnal bird activity, differed between females and males. During the night, more females stayed in the colony and males perform more nocturnal movements. During the day, females flew longer distances and their rate of visitation to the breeding colony was lower than that of males. In addition, the peak activity of the females was in the middle of the day compared to the peak activity of males which occurred in the early morning. Our findings help clarify how sexual monomorphism/ dimorphism influences parental care, including how it may affect movement, foraging and caring for the young during the breeding season. A future study quantifying the distribution of insects in time and space will assist in elucidating whether the two sexes respond differently to the abundance and distribution of insects in space and time.
