Field signs

- Leaf-litter thrown about under hedges as it hunts insects
Did you know?
- Winter blackbirds in Britain are joined by migrants from Scandinavia and the near Continent, so the bird on a January lawn may not be local.
- Once a shy woodland bird, the blackbird moved into British towns in the 19th century and is now one of the commonest garden birds.
Moments worth waiting for
- Rooftop song
A male blackbird sings from the chimney pot, pouring out fluting phrases as the light fades. - Worm hunt after rain
After a shower a blackbird runs, freezes, tilts its head and drags out a long worm.
Rare forms and local legends
- Leucistic blackbird
Leucism is a lack of pigment in some feathers. Blackbirds and house sparrows are the birds most often reported with it. The white pattern stays for life, so a local can recognise the same bird year after year (BTO). - Half-Moon
A local blackbird whose white crescent makes it recognisable year after year. Territorial blackbirds sing from the same high perch at dawn and dusk.
Photo tip
Low angle on the lawn after rain, when they hunt worms in the open. Sun behind you brings out the gold of the bill; a slow burst of frames when it cocks its head.
Be a good naturalist
Do not disturb nests in hedges: blackbirds desert easily in early laying. Keep cats indoors at dawn and dusk in spring.
The law
All wild birds, their nests and eggs are protected under the Wildlife and Countryside Act 1981; it is an offence to kill, injure or take them or damage an active nest.
