Common Nighthawk - Ph. Nick Myatt, Wikim. Commons |
One of the fascinating behaviors witnessed this year is exhibited
by swifts and a number of other bird species around the world: young of
the previous year travel back to act as "helpers at the nest" -
assisting their parents to raise this year's young. Read about this in Alexander Skutch's book: Helpers at Birds' Nests: A Worldwide Survey of Cooperative Breeding and Related Behavior. (1999, University of Iowa Press.)
