The Hooded Crow is mainly resident and an adaptable omnivore.
Roosting: in winter crows gather at communal roosts that can hold hundreds of birds.
Food: a scavenger and opportunist — carrion, food scraps, grain and small birds; it readily follows human activity.
Influx: the population is reinforced in winter by birds from the north and east.
Town life: the milder climate and abundant food waste of towns draw crows into urban areas, where they often gather in parks and at rubbish tips during the coldest part of the year.
