KL state school playing fields (12th and 13th July)

I have made two consecutive visits to the playing fields behind the KL state school.  Both visits produced small flocks of Black-headed Gulls (not including any other species), and 16 and 17 groups of Pied Wagtails respectively on the 12th and 13th July, (both groups containing 8 juvenile birds).  The 12th also produced 1♀ Kestrel whilst today's visit included 3 Green Woodpeckers (2♀'s, 1 juv.) and 1 juv. Black-headed Gull amongst the adults.
