West Park lake gets occasional visits from cormorants. It’s probably a good thing that they don’t take up permanent residence: they’re big birds with healthy appetites, and could possibly make a dent in the size of the fish population.
This bird, perhaps a young one, stayed for a few days during a cold snap two years ago. These pictures were taken as it paused from catching fish. It spread and shook its wings to dry them in the sun, then started to look around for a potential further snack.
