Wraysbury GP - 1st August 2021

 Only 5 nets up today with a total of 93 captures. Twenty of these were retraps, showing that Whitethroats and some Blackcaps are staying on site. We have been noticing that a lot of the birds do not yet appear to be gaining sufficient weight for migration. Of the adult Whitethroats, we are noticing that all are female with no sign of the males. As in spring the males generally seem to move ahead of the females.

Seven Blackbirds was above what we would normally expect and the presence of Willow Warbler, Reed Warbler and Sedge Warbler on the record sheet added to the sense that autumn migration is gathering pace.
