Everybody has a bogey bird; that one which you just can’t seem to spot. For me, and probably many others, this was the Bittern. I spent time hunting for this perfectly camouflaged heron at Attenborough Nature Reserve in Nottinghamshire, with no luck. My grandma once managed to spot one while I was distracted by, of all things, a Grey Squirrel. It was the London Wetland Centre in Barnes where the curse was finally broken and this site has provided multiple sightings since then each winter. Bitterns were declared extinct in the UK in 1880 due to hunting and wetland drainage. Thankfully, the species returned of its own accord as a winter visitor, and in a few places in the UK does breed here again. Hopefully, the sound of male Bitterns booming in the breeding season will be heard in London once more.
