Is it unusual to see Cormorants flying in large flocks and is there any significant reason for them to do this?
I spotted a large flock of 50-60 birds in flight while driving yesterday. I pulled in to watch for a while and noticed they were flying the same pattern, over and over - back and forth over a distance of 500m or so.
When I first saw them there was a single grey heron flying after them but within about 15 minutes or so there were 8 of them in pursuit.
I eventually lost sight after they dropped below the tree line but might be worth mentioning that this was a good 20-25 miles inland.
Is this usual?
