A morning walk in improving weather from Paisley to Glasgow produced some really excellent records including my first three singing Chiffchaffs of the year, single Grey Wagtails at two sites, a drake Teal roosting near the Leverndale Hospital gate and a Cormorant overhead at Cardonald Place Farm (plus two Goosanders and a Kingfisher). Two Ravens were noisily escorting a Buzzard over Leverndale Hospital and closer checking revealed a large nest on the east face of the tower. It wasn't possible to see over the rim, so occupation couldn't be confirmed (it is not the easiest site to check due to the close proximity of the neighbouring flats).
Did some atlas visits in Renfrew in the afternoon. Highlights were fairly few but included a flock of eight Linnets at the mouth of the Cart and two Teal off Renfrew Golf Course (where Coltsfoot was flowering in profusion).
