where do jackdaws nest
Breeding Edit. Jackdaws usually nest in colonies with monogamous pairs collaborating to locate a nest site which they then defend from other pairs and predators most of the year. Jackdaws nest in cavities of trees, cliffs or ruined, and sometimes inhabited, buildings, often in chimneys, and even in dense conifers.ackdaws are voluble birds. The call, frequently given in flight, is a metallic and somewhat squeaky, chyak-chyak or kak-kak . Perched birds often chatter together, and before settling for the night large roosting flocks make a cackling noise. Jackdaws also have a hoarse, drawn-out alarm-call.
