trophic

Lanner Falcons favour open grassland, cleared woodlands and agricultural areas. Breeding pairs tend to favour cliffs as nesting and roosting sites; however, they will use alternative structures such as trees, pylons and buildings. The dominant prey group is birds, followed by small mammals, reptiles and insects (Jenkins and Avery 1999). A generation length of 6.9 years is provided by BirdLife International (2014bd).
