At least three and potentially up to four Grey Herons were on a 200 metre stretch of the White Cart in south Cardonald today. One bird was seen flying off downstream followed by an immature (first winter) standing quietly in the shallows and two adults bickering under the Cardonald Place Farm Bridge before flying off upstream. I normally only see one bird along this stretch and then usually only in autumn or winter. The reaction of the local Mallards made me wonder if the herons were attracted to the area by the recent appearance of the first ducklings (the pale female had five ducklings nearby). Also notable today (possibly something to do with this being a particularly early visit) was the high number of singing warblers heard (within an area of less than half a square km) consisting of two Willow Warblers, four Chiffchaffs and an incredible six Blackcaps (plus an additional three non-singing birds). Two Stock Doves were singing, a Great Spotted Woodpecker called, the usual pair of Goosanders were loafing on a rock, a pair of Long-tailed Tits had at least one fledged young and the remains of a young Woodpigeon suggested a Sparrowhawk kill.
