Foraging

Largely acorns, but forages in all strata.E

Biology And Ecology

Breeding season March to June.E

Nest

Builds a fairly substantial moss and stick nest at mid-height.E

Brood parasite

Clamator glandarius (Linnaeus, 1758)F Cuculus canorus subsp. canorus Linnaeus, 1758G

Behaviour

A restless, active species which forms loose bands outside breeding season, oftenjooining with Black-Headed Jays and blue magpies.
Flight laborious with a slightly jerky action, wings almost clapping below body; usually keeps in cover, especially while breeding.E

Ectoparasite

Philopterus garruli Boisduval & Lacordaire, 1835H

Voice

Generally rather silent, but calls reported from the species's wide range include mimicry; varied conversational notes; a lot cu-cr-blink-blink; chorused kler_keee; loud, rapsing, drawn-out shaak, shaak; chuckles and whistling squeals.
