During the day I travelled to Wilstone to hopefully see (county tick) and photograph the Great White Egret. Mission accomplished on both counts.
Then in the evening I popped down to Amwell and, after a minutes at the viewpoint, both Barry Reed and Graham White called a Great White Egret, which landed for a few seconds opposite the viewpoint before carrying on towards Stanstead Abbotts.
As Graham White pointed out, I am probably the only person that has seen two separate Great White Egrets (the other one was still at Wilstone) on the same day in Hertfordshire.
I claim my prize.
