Session: 19/06/2022 06:00 to 11:00hrs
Notes: After a few days of hot sunny weather, it turned cold and cloudy
this weekend with rain about. Fortunately, no showers went through during the
session which proved to be one of the poorest since 1993 when we converted to
CES. Acrocephalus numbers are well down on the norm for visit 6. Not many reed
or sedge warblers appeared to be present on site including few seen or heard. We
expected numbers to be around last year’s visit 6 which was 49 with the same net ride
and length of net, even though 28% of that session were juvenile Blue Tits;
just one BT juvenile this visit. It looks to me that something has happened to many of our acrocephalus warblers in their winter quarters or on passage. Sedge Warbler numbers have been dropping for some years now, said to be the effect of global warming and the species travelling further north to breed than in the past. There are sign that Reed Warbler may be doing the same with birds turning up further north and west including in Ireland where they have until recently been unusal I understand.

towards winter quarters. One possibly two family parties of Magpie active all
morning included a bird that had killed a Water Shrew and was seen gulping it
down whole. The weather conditions subdued insect activity.
