A Roe Deer buck was grazing along the river first thing. A Grey Heron was standing on a stone in the middle of the river. At least five Song Thrushes were active around Rosshall Park. A Grey Wagtail was over the playing field there and I thought I heard the "hoo-weet" call of a (presumably wintering) Chiffchaff. Only six Black-headed Gulls were present at their usual wintering spot near the Cardonald Place footbridge. However later in the day, a noisy flock of twenty or more flew over downriver.
