The first half of today's exercise walk was through the north of Paisley including a corner of  farmland at Arkleston Road, some small patches of woodland and some amenity grassland, but mostly buildings and tarmac. The most interesting record was of two singing Skylarks. However Chiffchaff, Blackcap and Willow Warbler were heard and other good birds included both thrush species. The second area covered was the south east of Renfrew. Quite a large area of the square is inaccessible, being within a large industrial estate. However some good views could be had from around the perimeter, allowing potential breeding by Common Gull, Lesser Black-backed Gull and Raven to be recorded. Similar to yesterday's walk in Renfrew, no Chiffchaffs or Willow Warblers were heard (except beyond the edge of the square) and only one singing Blackcap was counted. However a singing Whitethroat was my first since I began walking around my local squares. House Sparrows were extremely common and the behaviour of Starlings suggested that chicks are in the nests and needing fed.
