Black-crowned night herons breed in Somerset!

Recently, I was reading the Birdwatch magazine I get every month, something caught my attention; there was an article saying that some black-crowned night herons have bred in Somerset!!!  This is the first record of them breeding in the UK, and they even fledged young (I’m not sure if the weather was much cop, because it deterred other rare breeding birds such as the bee-eaters in Nottingham, which weren’t successful).  They were at a site near Graham Hall.
