Very elusive Dusky

On Thursday 20th March, a very early start 6am at Oulton Marshes or Fisher Row revealed 2 Redwing perched on top of 2 tall trees by the "Bowl" opposite the Old Tea Gardens path. Up to 5 Chiff- Chaff were seen singing through the visit too. Eventually locating the mega elusive Dusky Warbler (heard only) to a row of bushes extending south from 2/3 way along the path, I heard the disinctive "tak" call 3X in quick succession at 7.30pm but failed to see it and had to leave at 7.40am I saw Tony B and showed him where to look, 5 minutes later he saw it! On Friday 21st March, I arrived again early and heard it again "takking" 8.30am but just couldn't see the bird. Although I saw a bird flitting around way back in the bushes which could have been it. A Chiff- Chaff moved through the bush. I was joined by Don & Gwen and at 9.15 we heard a constant "taking" but we still couldn't see it. The calls were getting louder it was getting closer and we still couldn't see it until Gwen saw a movement to the left of the bush. I picked it up at 9.20am and finally after 5.5 hours of looking, I saw a grey bird fly and perched near the top of the bush, it showed out in the open for all of 5 seconds but enough to confirm it was the excellent Dusky Warbler showing dark eyestripe and white supercilia. It then flitted back and out of sight, time to go to work!
