ROOKS : Corvus frugilegus
Where to see them : Widespread across West Dunbartonshire, but note that younger birds can easily be confused with other crows.
This is a very distinctive bird with a bare, greyish-white face, thinner beak and peaked head. Yet it is often confused with the carrion crow. The bare area at the base of the beak only appears in adults and the near fully grown young look more like small carrion crows. Rooks are very sociable birds and you're not likely to see one on its own. They feed and roost in flocks in winter, often together with jackdaws.
See the notes above to distinguish between carrion crows and younger rooks.
