The red admiral is an unmistakable garden visitor. This black-and-red beauty may be seen feeding on flowers on warm days all year-round. Adults are mostly migrants, but some do hibernate here.

The all-black carrion crow does not nest in colonies like the similar rook. It can be seen almost everywhere.
