What defines the "Sallying" foraging style in warblers?
Answer
Darting out from a perch to catch flying insects mid-air
Sallying is an active foraging technique characterized by rapid, short flights initiated from a stationary perch. The bird darts into the open air to intercept aerial prey, such as gnats or flying ants, before immediately returning to its original perch or a nearby one. This contrasts with gleaning, which involves picking prey off a substrate, or probing, which involves searching through ground cover. Sallying requires excellent aerial agility to successfully capture moving, airborne insects.
