Yes SRS, from the little I saw of the one crow, they are quite intelligent in their own way and curious creatures in their ways. Not sure I agree with all they do, eg. I think it was one of them or relations that took a couple of blackbird chicks this year. But a crow remains interesting.

That said, blackbird (another one) was also interesting. She came down, picked bits of dry cat food, Would nick a raspberry etc. In between periods of my own bad health, I built her personal table to save her from the cat risk and she took to it.
