Back to blackcaps

• Although the male has a black cap reaching to the upper part of its eye, the cap is actually chestnut brown on the female and juvenile

• The garden warbler, with which it is sometimes confused, is much browner in colouration

• Blackcaps are a similar size to robins, measuring about 5in long and weighing barely an ounce

• They are predated by sparrowhawks and domestic cats

• The typical lifespan of a blackcap is two years, but the record age for a ringed bird is 10 years, eight months and 15 days
