Black-necked Grebe - one at the East Res. from 28th to months end
Hobby - two singles at the reservoirs, 13th & 26th
Spotted Flycatcher - one to two on several dates from 22nd to 31st
strong hirundine passage errratically throughout the month

Curlew - at least two calling overhead on the night of 29th
Red-crested Pochard - two from 25th to months end
Being in Scandinavia for much of the month prevented patch coverage on my part, but Laurence (and several other observers) maintained a regular presence at our favoured local sites - the Reservoirs, Clissold Park and Abney Park Cemetery.
Details of the above highlights can be found in Laurence's daily entries below.
A more systematic summary at the end of each coming month, with photos, highlights and full counts, will resume from September onwards.
