Bluebell and the introduced Spanish variety.
As we approached Avon Lane we finally heard the song of a Lesser Whitethroat but typical of the species, it was well hidden in the hedgerow and only gave the briefest of flight views as it broke cover and was chased off by a male Blackcap. Further up the lane two Sand Martins flew over and Swallow and House Martin were added to our list as we reached Avon Farm.
Gradually the cloud broke and some weak sunshine enticed some butterflies onto the wing as we walked the section to Swineford Lock and the river towpath and these included Orange Tip, Green-veined White, Speckled Wood and towards the end of the walk, two Holly Blues.
A female Sparrowhawk also put in an appearance and two Cormorants were perched in their usual tree on the river bank. A singing Goldcrest gave very good views over the path passed the Water Treatment Lagoon and the walk concluded with further excellent views of two Mistle Thrushes on a grassy bank.
