Yeah, that was like my only other sighting of a bittern. I thinks that's the most common type of sighting that people manage. Early in the morning or at dusk. Anything else for any amount of time requires good luck and a lot of patience.
We thought we had a good chance of a sighting at Potteric Carr though. Bittern have attempted to breed in these areas and around the Humber especially, but so far unsuccessfully. But with a number wintering in the North East like this it gives us the opportunity to see some.
Potter Carr nature reserve is a part of the Yorkshire Wildlife trust and had its own independent website. They have daily update of what has been spotted, including number of bitterns and which particular marsh they were seen at.
If any of you guys are in the area, now may be a good time to give it a try.
