Gulls at the Pembroke Dump

We were spoiled rotten with an exceptional gull study at the Pembroke dump today (15 November 2017). Birders must sign in at the front gate but are free afterwards to study gulls at close range within the facility grounds. Because the gull study is so good and so valuable to EOB birders, I have availed three gull-specific tours to the Pembroke Dump. Please see my outing schedule for further details: http://eontbird.ca/?page_id=7

It’s so helpful when they stand right next to one another Great Black-backed at rear; Lesser Black-backed at front.
