breeding and migration round up

Buzzard; seem to be two different juveniles in the north end of the reserve.
Sparrowhawk; judging by the mewling calls successful nesting as per last few yeaers in hawthorn wood
Moorhen; as often with this species a protracted breeding season, currently a brood of 5 near meccano with a brood of 2(maybe3) close by. Shortly we may see first brood birds feeding chicks.
had been disappointed in numbers reared so far but looking better now.  High rates of predation seem to occur is it rats or gulls or even something from underwater? Also are birds at the north end being pushed out by coots which seem to be spreading from town centre.
Swift; our birds seemed to leave about 24 July not sure about breeding success but numbers reduced on 5 years ago. Odd birds drifted through up till end of last week.
Migrant Warblers; picked up in the last few days the hot spot being the lower western boundary of barleyfield.  Plenty of common whitethroat, few blackcap, willow warbler in ones and twos and chiffchaff. Highlight this morning was a superb juvenile lesser whitethroat from same spot.
Waders; none as far as I know in the valley, just outside on the i54 pool off wobaston rd a green sandpiper in mid july and a wood sandpiper on the last day of july.
finally a common blue butterfly on the barleyfield was a nice spot this morning,
