Saw my first ever Blackcap this morning and spent 45 minutes tracking down a Cetti's.
Jeez the Cetti's are hard to see but when you hear that call they are pretty recognisable.
Used all my skills and fieldcraft to find it............well ok then i sat on the bench where i heard it call and waited

............knew it couldn't hide forever.
Only got a quick view as it appeared at the waters edge then flew into some reeds nearby but it was great..............i remember reading about these when i first started bird watching and thinking to myself that i would never see one.
ps Jonny it was at Warnham.......have you seen it yet?
