Roosting Starlings at dusk make a wonderful sight

WEDNESDAY 19 NOVEMBER 2008

A colder day, with a fresh westerly wind blowing bringing down the overall temperature. Dry throughout with the odd bright period.

Skirting around the Hunt's Green area, a raptor survey revealed the presence of 3 RED KITES, a Common Buzzard and a single male Common Kestrel.

AYLESBURY

Two RED KITES were over Long Meadow in Aylesbury with a third bird over the Tring Road; all at 1310.

BROUGHTON POOLS, AYLESBURY

Following a call from Mike Collard, I followed up a report of a drake American Wigeon or hybrid - as I expected, it related to an adult drake CHILOE WIGEON present at Wilstone Reservoir earlier in the month. Interestingly, this escaped bird was feeding alone on the closest bank of the first trout pool. At the back of the pool were 22 Eurasian Wigeons (14 drakes).

There were also 3 Grey Herons at the pools, a single fishing Cormorant and 3 Redwings in adjacent hedgerows.

GREY WAGTAILS - communal roost at the edge of the reedbed involving 7 birds, a single male of which was extremely vocal as dusk approached.

Reed Bunting (3 roosted)

*CORN BUNTINGS - a total of 120 roosted. The first 45 arrived before 1530 hours, perched up high on the trees above the main causeway. These were followed by a single at 1540, 6 (1542), 9 (1544), 21 (1555), 10 (1557), 5 (1559), 10 (1601), 9 (1604) and the last 4 at 1609.

**COMMON STARLINGS (1,600+ roosted) A remarkable spectacle: the first flock of about 500 birds first started wheeling around at 1550 with smaller groups of up to 120 birds joining frequently from thenon. The flock gradually got larger and larger, with the usual acrobatics following. At around 1605 hours, one group of 650 birds broke away and flew towards us and went in with a loud 'whoosh' into the reeds just left of the new cut through. The sound was amazing. These birds then gradually moved from the left side of the cut to the right hand side, where there is more protection. The remaining 1,000 or so birds then roosted at the opposite end of the reservoir, in the smaller reedbed not far from the canal.
