* The main breeding habitat for Blackcaps is mature deciduous woodland.

* Eggs take about 12 days to hatch and both parents take turns to incubate the eggs. Once hatched, the chicks take another 12 days, approximately, to fledge.

* They eat both insects and fruit. They tend to eat insects earlier in the year, for protein, then fruit later in the year to gain energy for winter migration.

* They are resident in England, but only can be found in north and west Scotland during the summer months.
