Dirty Twitching

 [Black-Crowned] Night Heron

This afternoon we were due to be at RSPB St Aidan’s to hear booming Bitterns and hopefully spot the fiery eyes of Black-necked Grebes.  However, when the group arrived at this very exposed site, it was blowing a gale and soon there was a severe wintry shower. The sky was promising more.  We enjoyed the sight of a Little Owl tucked into a woodpile, and a pair of Kestrels on the marooned industrial machine.  There was a chance that it was more sheltered at Ossett, and an even slimmer possibility that they might catch a glimpse of two Night Herons sleeping the day away behind some dense vegetation. So, to escape the worst vagaries of the weather we drove 30 minutes to the riverside location.

I went to Ossett before the session, but this is all I was able to see.

At first the view of the two Night Herons was almost identical to that in the morning - obscured and only partial.  However, after around 30 minutes one of the birds emerged and headed down towards the level of the river.

Final Sighting
There were also some Goosanders on the river, plus a male Grey Wagtail.  Our watching of the Night Herons was punctuated by a Weasel, which swam from our bank of the river against a strong current to the other side of the river.

During the Easter weekend the Night Heron showed even better for the big crowds.  It was noticed that these scarce birds were much more tolerant of noisy crows than our bog-standard Grey Herons.  For some reason the Ossett couple were best-placed to make an early visit to see these scarce vagrants.
