Another early start enabled me to get to a local Black Grouse lek just before dawn. As the light improved it became apparent that at least four males were present. They were much more active than I had witnessed before - possibly due to the presence of a female in the middle of the group. After about ten minutes I slipped away, leaving the birds to keep fighting.
The next stop was Rowardennan on the eastern shore of Loch Lomond. Five Goosanders were sailing serenely on the loch. Nearby, two pairs of Common Gulls were squawking loudly in reaction to a Herring Gull which had alighted on their nesting island. Two Pied Wagtails (presumably a pair) were bickering on the shore and a Great-spotted Woodpecker was drumming nearby.
Spent the afternoon enjoying the sunshine at Irvine. Notable sightings there were two Sandwich Terns repeatedly catching small fish at the mouth of the River Irvine, a male Stonechat in scrub behind the Beach Park dunes, singing Chiffchaffs at several sites and a surprising 33 Wigeons on the boating pond behind the Magnum Centre. There were plenty of common birds on the saltmarsh and mudflats opposite Irvine shore. Also present were five Grey Seals pulled out on the mud and a Roe Deer hiding at the edge of the marsh.
Heading home, two Hooded Crow x Carrion Crow hybrids were near Fairlie and the verges around Dalry were full of spring flowers including Coltsfoot, Lesser Celandine, Dandelion, Daffodil, Primrose and especially Butterbur (with the most extensive patches of the latter I have ever seen).
