Social Behavior of White-throated Swifts
Thomas P. Ryan and Charles T. Collins
ABSTRACT: The social behavior of the White-throated Swift includes Chases Without Contact, Chases With Contact, and Courtship Falls. These behaviors have a strong seasonal pattern. Chases Without Contact were the most common interaction and occurred most frequently during the winter and spring. Chases With Contact and Courtship Falls occurred less frequently and peaked during spring prior to breeding. White-throated Swifts also have social behaviors that may be termed the Raised-Wing display, Screaming Party, and Silent Dread.
