Characteristics of the hunting behavior of the Redfooted Falcon (Falco vespertinus) in South-Eastern Bulgaria
Journal Title: ZooNotes - Year 2018, Vol 125, Issue 0
Abstract
Hunting behavior was studied in a small breeding population of Red-footed Falcons in SE-Bulgaria and in a transitory migrants of the same species. A total of seven types of hunting strategies were performed by the Red-footed Falcons which can be rapidly switched from one to another in relation to the available type of prey, the speed and direction of the wind. It was recorded that the hovering series were longer in calm weather (wind speed < 2 m/s) and in strong winds (over 5 m/s) than in moderate winds (2 – 5 m/s). Difference was found in the mean length of the hovering series between the migrating and local breeding Red-footed Falcons. The hunting success of the finished attacks of the Redfooted Falcons was in overall 59.6 %.
