A walk through Rosshall and Crookston first thing produced the following:
A pair of Stock Doves together (the male singing) in Rosshall Park
A pair of Ravens calling and circling their nest site (but no sign of any chicks)
A Kingfisher on the river near Bonnyholm 
Singing Collared Dove and Goldcrest at single sites 
A male Goosander on the river (is the female on eggs?)
A Grey Heron under Rosshall School bridge
Blackbird, Starling and Mistle thrush all feeding on mown grass (Starlings seen carrying food back to nests)
Later in the morning, what sounded like a Red Grouse was calling in the background of the RSPB Abernethy webcam.
Some interesting sightings at Hogganfield Loch this afternoon consisted of:
Several pairs of Mute Swans on eggs
A pair of Canada Geese resting on one of the new "islands" (with another pair at the car park)
Still plenty of Goosanders present (22) but Goldeneye all gone
Several Grey Herons visiting nests on the island
Clouds of Sand Martins and Swallows
A Common Sandpiper on one of the mini islands.
This evening, single Pied Wagtails were at the south entrance to the Clyde Tunnel and at Helen Street, both Glasgow.
