James called me on Friday to tell me he was going to look for the Greenish Warbler at Cromer, but with rain chucking down and other things to do i decided to try on Saturday. Again on a tight schedule me and Laura arrived at Warren Wood but could only stay about an hour. The Greenish and W Bonelli's both had been heard but only briefly seen. 3 Chiffchaff flitted about in the bushes bordering Happy Valley along with a family of Chaffinch, 2 Blackcap and a lone Whitethroat, while 5 Swifts and a few Sand Martins flew overhead. Just before we had to leave the tit flock came through the area we were watching, complete with the Bonelli's Warbler it tow. I only got brief views before the bird was chased off by the male Blackcap but this was enough for me to see it's very pale underside and yellow tinge to the wing. After physio i returned mid-afternoon with Gary, and it didn't take long for us to hear the Greenish Warbler call in the Holm Oak on the hilltop, the same place Gary saw the bird in pouring rain on Friday. Gary found the bird but no sooner had he located it a Chiffchaff arrived and chased it up higher into the canopy. Despite waiting around another hour and half we only heard the Greenish Warbler once more and probably heard the Bonelli's Warbler also. As another storm threatened we headed back to North Walsham. Brief views of both birds, but many people will struggle to even see them in the leafly sycamore, and hopefully if this mini influx of Greenish continues and i'll catch up with another bird.
