of these information pre-2010 was from our very personal county the place a stonking male
was noticed holding territory in Brightwell-cum-Sotwell in June 1988.
Apparently very aggressive and instigating mid-flight duels with native flavissima,
this chook was by no means noticed to be correctly paired up regardless of its greatest
efforts. This report was made much more attention-grabbing when in the identical precise
subject that yr, a male flava paired with up with a feminine flavissima
fledging three younger!

Thomas Miller, the finder of each of the county’s newest Gray-headed
Wagtail
information, has helpfully offered some extra ID information on
distinguishing feminine flava and thunbergi been considerably of Yellow
Wagtail

attention-grabbing species shifting via the county. The primary spotlight got here within the
early a part of the month when a pair of Avocet turned up at Peep-o-Day
Lane
on the 6th. Fairly a late report with most birds already on
nests across the nation, there was some transient hope that these birds would set
up store within the county when the birds remained for a few days after.
Sadly, the birds departed by the tenth, regardless of behaving
territorially within the time they have been right here.
