The lower image is a view of Pitstone Hill (Dave Bilcock). This is where the ringtail Montagu's Harrier was lasts een this morning.
FRIDAY 15 AUGUST
As yesterday evening's electric storms moved away to the east, the Chiltern district became calm with a full moon. Consequently, this morning dawned clear and dry, with blue skies prevailing and a light SW breeze. With the sun out, temperatures soon climbed, peaking at 72 degrees F mid afternoon. With such good weather, it was hardly surprising that migrating raptors would take to the air, with both MONTAGU'S and MARSH HARRIER recorded during the day. Unfortunately when DB first discovered the ringtail Montagu's, I was unable to respond, and within ten minutes it had disappeared. Subsequently, when SR found the juvenile Marsh Harrier this evening, I was four miles away, and again dipped out.

**MONTAGU'S HARRIER - PITSTONE HILL - Dave Bilcock
First for the Recording Area this year - species 165
The bird, a ringtail, most likely an adult female, was initially seen at 0730 hours sat on a post, a quarter of the way along the fence line between the bottom of Incombe Hole and Pitstone Hill car park. Unfortunately, no sooner had Dave 'scoped it, it took flight and then slowly quartered the large corn field by Down Farm and the fields below Pitstone Hill. It last disappeared behind a ridge in the field to the SW of Pitstone Hill, where it may have landed. It was not seen again all day, with Dave and Steve looking intermittently through the day and LGRE and others this evening.
WILSTONE RESERVOIR
(1450-1900 hours; with Joan Thompson; later with SR, MW, IW, AN)
*ICELANDIC BLACK-TAILED GODWITS: the 6 birds that flew in to Wilstone Reservoir at 0730 hours (Steve Rodwell et al) remained all day, commuting between the large expanse of mud to the left of the Drayton Bank Hide and the mud fringe in front of the reedbed on the right hand side. They appeared to be a family party, with a moulting adult (largely in winter plumage) and 5 identically plumaged juveniles. The flock were rather flighty but showed extremely well at times, allowing a number of observers to photograph them (see above) (LGRE, DB, MW, JT,JP, AN, et al).
