Common Shelduck: 3 males were near the Leg of Mutton.
Lesser Black-backed Gull: 2 birds were by Heron Pond.
Wheatear: my first bird of the year in the park was in the Skylark protection area.
Reed Warbler: 3 birds (2 singing males) were around the pools in the Brewhouse Meadow. Possibly one of the males was by the Iron Bridge earlier.
There were no other significant sightings
I have seen more wheatears on the ground in the park than I have Lesser Black-backed Gulls.
