Thanks - I’ll cetainly look it up!

Crows, like all other corvids, are very intelligent indeed.

Konrad Lorenz, a long time ago, did some excellent work on rooks.

And if you want to learn about ravens, there is none better than Berd Heinrichs, a professor in Vermont, who did some outstanding field work, and wrote some wonderful books about it.

‘Ravens in Winter’, and ‘The Mind of the Raven’ for example - they are out in pb!
