Blackcaps migrate to the tropical part of Africa in late summer where they over-winter, returning in mid to late March and as late as July to nest and breed. They nest in high hedges, woods and gardens that have bramble bushes that give them some protection while raising their chicks. The nest is well hidden inside the hedges and brambles and is made from grasses and small roots/twigs. The nest is loosely built but neat and is lined with fine grass and hair. The eggs are a creamy colour with brown speckling. Blackcaps lay 4 to 6 eggs and both adults incubate the eggs for 12 -14 days. The chicks are fed by both adults with a wide variety of insects, flies, small vertebrae and caterpillars, and the chicks fledge after two weeks. Both adults will continue to feed the chicks for a further 10 to 14 days until they become independent.
