In January, mixed flocks of Blue Tits, Great Tits and Long-tailed Tits move around foraging for food, and may be accompanied by Nuthatches and Goldcrests. Winter thrushes, like Redwings and Fieldfares, are still about, and both Mistle Thrushes and Song Thrushes may be heard singing.
Some birds, such as Carrion Crows, Rooks, Jackdaws, Starlings, Black-headed Gulls and Wood Pigeons, fly daily between their communal roosts and feeding grounds. At dawn, they leave their roosts to feed, sometimes many miles away, then make the return journey at dusk.
The RSPB Big Garden Birdwatch takes place this month. Over 500,000 people take part each year, counting over 8 million birds. All you have to do is record the highest number of each species you see at any one time in your garden or local park for an hour on one of the days.
