MARSH WARBLER - Acrocephalus palustris
Early morning on August 22nd an unidentified
Acrocephalus warbler was trapped and ringed at Grebe Pond, Northwick Warth.
It was later believed to be this species from photographs and
biometric details taken at the time.
An adult was noted
on passage sometime in June at Stoke Gifford.
Two were identified sometime in June at
Patchway. A nest with three eggs was photographed in a bean crop
and it was assumed that two adults were present.
This is the first
documented reference to this species in S. Gloucestershire.
