Heliport seawall Knot have been a distraction with the latest spring tide sessions in the failure category due to bits of disturbance at bad times and arriving too late on a key day
Rose sent me the Ed Keeble method as applied to the heliport roost a couple of days ago and her estimate fits very well with the easier counts of birds spread over the feeding areas off Heysham Head. Thanks for this.
I think there are about 80-100 of these boxes. I made copies of the 10 boxes till they roughly filled the area.
So conservatively 4000-5000.
