After over a month away from the Docks it was all hands on deck today for a complete census of the site with even the unexpected visit to Bidston Moss NR with Luke Anderson. Starting the day off at the Morpeth & Egerton Docks all that was to be offered were the resident pair of Mute Swans, 1 Common Sandpiper, 2 Great Cormorant & a flock of 8 Black-headed Gull, 1 Great Black-backed Gull, 4 Lesser Black-backed Gull & 5 European Herring Gull.
The East Float was on fire today with the Common Tern colony producing a record count of 110c Common Terns (19 Juv) & 1 Roseate type-Tern in flight when the colony was disturbed. After discovering the colony only 3 years it's been fascinating to watch the colony (Cheshire's only tern colony!), unfold with year upon year more and more birds flocking to the docks to breed; In 2015 30c adults were counted, 2016 that number rocketed to 60c and today that record was utterly smashed with 110c birds tallied.

today the question of how many were adults and how many were infact juveniles is
unclear; however a total of 19 juveniles were counted (Image - Elliot Montieth)
A supporting cast for the East Float consisted of 1 Great crested Grebe, 20 Greater Canada Geese, 17 Great Cormorant, 2 Great Black-backed Gull, 7 Black-headed Gull, 5 Northern Lapwing, 5 Common Ringed Plover with an rather unexpected discovery being that of a singing male Common Whitethroat on the grounds of the clock tower.

is an uncertain one with developments posing a serious risk to the species next year (Image - Eliot Montieth)
Next up at the Gull Roost only a handful of Lesser Black-backed Gulls were around with 2 1st summer Great Black-backed Gull; The vast majority of todays roost was located along Wallasey Bridge Road that held host to Black-headed Gull (55), European Herring Gull (112), Lesser Black-backed Gull (78) and with first adult Common Gull (2) were further located amongst the roost.

& winter visitor (Image - Elliot Montieth)
After dropping into Bidston Moss NR (See here), the pair of us headed over to Seacombe Ferry for a sea watch of the Mersey to see weather or not the Roseate Tern's that had been showing on and off at Seaforth NR had ventured down river to associate with the dock terns. Over the half an hour that was spent observing the Mersey that totals came tot eh following: Great Black-backed Gull (2), Lesser Black-backed Gull (17), European Herring Gull (32), Black-headed Gull (49) and the highlight was a Mediterranean Gull that came to bread for a matter of seconds before turning into a ghost.
