Playing field behind the KL School

I was glad to get out past 6pm this evening to go behind the KL School to check for any probable gull flocks after coming back from my first day of school this term.  Unfortunately on arriving the gulls decided to fly just  as I arrived after which they landed in the far southern corner of the playing field just out of sight.  However a few birds of note did pass through including 1 Hobby that flew low over the northern length of the field in a NNW direction, in the exact same direction that the previous Hobby took on the 23rd August.  After c.30 minutes the gull flock took flight again with half the flock deciding to remain at the back of the field whilst the rest flew east towards the canal and fishing lakes in the village.  The remaining flock only consisting of Black-headed Gulls and 3 Lesser Black-backed Gulls.  Next I decided to scan the fields adjacent to the playing fields on the opposite side of the road were, soon after beginning to scan I noticed a large mixed flock of 70+ Carrion Crows and Jackdaws come to roost in the woodland in Long Dean Nature Reserve at 7:30pm.  1 Little Egret was also a first for my Kings Langley list and was flying in the direction of the fishing lakes in the valley from a NNW direction.  Despite the fast fading light and grey sky bringing rain a Muntjac Deer was still visible from Barnes Lane as I viewed it walk across the grass field east of Woodlands Road.  I finally made a late night visit at 8:00pm to the KL Woods to check whether the bait of peanuts that I had previously laid out for Badgers in the ditch had worked as I found a group of burrows in the SE of the woodland that might be belonging to them.
