Turdus pilaris Linnaeus, 1758 · drozd čvíkota · Fieldfare

Distribution

It breeds across much of Europe and northern Asia, with northern populations moving south for winter. In Slovakia it is a regular breeder and a numerous passage and winter visitor. Winter flocks include arrivals from the north and east, so their size does not directly reflect local breeding numbers. Fruit availability strongly influences where birds occur.

Habitat

It nests in riverside trees, avenues, orchards, parks and small woods beside open country, often feeding on meadows and lawns. Winter flocks move between rowans, hawthorns, gardens with fruit and patches of unfrozen soil.

Breeding

The mud-reinforced cup nest is placed in a tree. Birds often breed in loose colonies, though solitary nesting also occurs. A typical clutch contains 5–6 eggs; the female incubates and both parents feed the young.

Food

Earthworms, insects and other invertebrates dominate during the warmer months. Berries and fruit become more important in autumn and winter, drawing entire flocks to productive trees.

Interesting fact

When defending a colony, Fieldfares may mob intruders together and strike them with droppings. Loud chattering helps locate a flock before individual grey heads and chestnut backs can be distinguished.
