Crows & Allies
Medium to large birds; many species are black or black and grey; others are pied; others are more colourful or well-patterned. Eight species breed in the UK; there are many others around the world. Most crows are adaptable but often shy where persecuted; in towns, some become tame and may visit gardens. They all have strong, scaly feet, and stout (or downcurved) bills, mostly with a small patch of bristly feathers covering the nostrils. Northern populations of some species are migratory or nomadic, others are entirely .

Starlings
A family of small birds in Europe, Asia and Africa; many are strikingly coloured and iridescent. One species is regular in the UK, both as a resident and as a winter visitor. Starlings are almost thrush-sized, but more upright, on strong legs, with short tails, pointed wings and sharply-pointed bills. They are also more social, forming closer, often much larger, flocks and feeding quickly in busy, squabbling groups where food is abundant.
