Sightings 40 Species: Another quiet morning with little visible movement. A few Blue Tit calling from the reed bed; only one adult captured though. The usual squabbling Water Rails heard; probably three breeding pairs in our part of the bed this year. At least one pair of Reed Warbler still active, the other adults probably migrants and the Sedge Warblers are  moving through or from the surrounding area. A big female Sparrowhawk flew over with prey and the buzzard nest over the back is getting very noisy. Three swifts over could be the last of the year, most have vacated the Newbury area by the first week of August.
