CETTI'S WARBLERS in Marsworth scrub

Two CETTI'S WARBLERS seen today in trees by the outflow next to the reedbed on Marsworth (approached from the road end). Looked like an adult and a juvenile. Saw the adult in the same place last week so good chance it may hang around. They both showed well only a few metres away. No sign of any spot flys here or at Wilstone (Dave Hutchinson)
