Location:

Session: 03/05/2025 06:00 to 11:15hrs.
Present:
JHW,IW,JL,RAD,CMD,IEW,NC.
Weather: sunny periods, cool, light breeze.
Nets: 198M long reed bed ride up from 06:30
to 10:30hrs.
Lures ():, None
Notes: The first CES visit of 2025 and a total of 24 looked low
and maybe the reed cutting and power line temporary access might be a factor. A
look at the first visit totals since we started in 1993 showed the average to
be 32 (range 2015 – 10 to 2004 – 63) making this visits 24 total on the low
side of average. There was a lack of species visiting the reed bed periphery such as Chiffchaff, Robin, Blue and Great Tits etc as can be seen by comparing the 2024 matching visit list. Hopefully there are still some
acrocephalus warblers to return. Looks like the St Marks Road ringed 2021 Blue
Tit has a territory near the reed bed as it was also here on the 14/04/2025; 5
years is a good age for a Blue Tit.

could find it. Several gulls quite high up looked to be feeding on insects.
