Goldfinch Montrose Wildlife Centre

Took a drive out to Montrose Basin this morning and there were three Herons standing in a row on rocks. Captured some super stances, but when I downloaded to my laptop they were all very blurred. Due to fog I expect. However, there were a few Goldfinches feeding and despite photographing them through dirty windows I got quite a few fairly sharp shots. I have sharpened and cropped this one.
