An early tickle

An early start at the crescent before the winds got up. Not very many dog walkers around this morning. However, there has been a blue-green algal bloom in the main lake for a week or so. These winds will shift it by creating turbulence and chilling the water temperature.

First up was my first moulting Blackcap of the year, a male with two primaries dropped on both wings. The main thrust here is always the Reed Warblers. We can't get into this small reedbed as the sub-strate is very unstable (an old silt trap) if you continually walk on it. Therefore we suffice with ringing the perimeter paths. Today it was 15 birds in total, with 7 retrap adult Reed Warblers and 3 juveniles.

With the absence of dogs, some of the 100 or so swans came to the beach, (bottom right corner of main lake - see map), to haul out and do a bit of 'toiletry' and 'have a natter'.

"Here we come"
"Now for a good scratch"

The end tally was 15 birds including 8 recaptures:
Great Tit 1 juv
Garden Warbler 1 juv
Black cap 1 juv (1)
Sedge Warbler 1 juv
Reed Warbler 3 (7)
One of the male Reed Warblers was ringed as a 6M (hatched 2 years earlier or before) in 2006, making it at least 6 years old and another one was a 6Female when caught in 2007. This year to date, I have caught 17 males, 10 females, 5 unsexed (poss females as they were caught early on) and 3 juveniles at this tiny reed bed.

Today's surprise extraction ...
... only the second this year over the whole site.
