Many songbirds produce simple, species-specific flight-calls. Some fundamental features of flight-calls remain poorly known, including their functions and variability. I reviewed available information on flight-calls and studied: 1) relationships between calling and weather; 2) seasonal flight-call use in warblers; 3) inter- and intraspecific variation in warbler flight-calls; 4) methods for analyzing flight-calls; and 5) relationships between warbler flight-calls and ecological and evolutionary characteristics. I examined relationships among call counts, weather, and bird density. I studied flight-calling in warblers during migratory and non-migratory periods. I recorded flight-calls from captive warblers to evaluate inter- and intras...
