Sabine’s Gull

Hadn't a lot of faith in the latest depression - centre too close and too fast and localised with a bit of  N in the wind.  A couple of close Leach's Petrels were therefore a nice surprise and the Sabine's Gull was even better!

Sabine's Gull - juv around seaward end Heysham two and the red buoy area 1105-1145 at least 
Leach's Petrel - one out 0750 as viewed from the north wall, one lingering in the harbour mouth, then out at about 0845 as viewed from the back of the harbour
Gannet - adult on water flushed by ferry then flew in
Sandwich Tern - at least 7 out
Arctic Tern - 3 adults on outfalls
Little Gull - adult and 2nd W outfalls
Guillemot - one in
Kittiwake - 12 on outfalls first thing, two out (6 x 1CY), 29 behind IOM ferry
Med Gull - not counted but 15+
Pink-footed Goose - 18 SE
