Are crows and jackdaws the same size?

I have photographed quite a few kestrels but this one looks different to me, the fan of the tail is white with black ends, most of the photos I have taken is a brown fan. Any comments would be welcomed...

Geese

Yellow and white finch?

Please identify this bird in Shrewsbury, Shropshire

Accidental Snipe, I think?
