Behaviour

Doi Phu Hom Pok NP, Thailand, 20 December 2017

Usually a very shy and wary bird, keeping in dense foliage. However, in city parks birds can become very confiding. Normally solitary or in family groups.

Diet

An omnivorous feeder. The diet includes invertebrates (notably caterpillars and beetles) but also eggs and nestlings and a wide variety of seeds and berries. Does visit garden bird tables where unmolested.

Breeding

Breeding starts in April in most of Europe. A pair stays together several years, possibly even lifelong. The nest is built by both sexes. It's a platfrom of twigs, placed some 4 to 6m above the ground, usually well concealed by foliage and near the tree centre. Lays 3 - 10 eggs (chiefly 5 - 7) which are incubated 16 - 17 days by the female. The nestling period is 19 - 23 days.

Vocalisation

The alarm call is a harsh, rasping screech. It is a great mimic.
