Birder mostly covering South Gare to Saltburn, Scaling Dam Reservoir and North Tees Marshes. Occasional trips to Shetland, Speyside, Norfolk, Suffolk and Cornwall.
Only seen by the photographer who was not really aware of Oriental Turtle Dove. This is is the best (of 3) image I have seen and I assume Bob posted his best photos. A lot of people looked for it extensively. It seemed fairly obvious that it must be Oriental. Your photo improvements are interesting

Friday info is in RBA history, Steve. My pager must have a reception problem.

Thanks, Colin. Ironically RBA broke down a few days ago so no messages for about 10 hours but it was up and running yesterday. I thought it odd as Graeme and Martin Blick are very good at getting info out on Twitter. I was sitting at Holme Fleet when all the action was happening a mile away!

Thanks, Steve. Have found these now in the RBA history data but sadly they did not reach my pager for unknown reasons. I heard later yesterday that it had been seen on Friday afternoon and some people had got that news but not on RBA. I'd have been looking for it on Saturday morning had I heard.

Thanks, Gary. I thought RBA and Birdguides copied eachother so that's bad news.

First mention of the White-tailed Eagle on Blue Sky or Twitter or RBA that I have seen. Very odd that it was kept so quiet given the lack of gamekeepers on Seal Sands!

It was there this morning but very elusive, in the extreme right hand corner of the largest lake (with c. 500 Greylags) so often disappearing behind the high reeds.

Actually a juvenile Herring Gull. Juv LBBG has solid dark outer greater coverts contrasting with notched inners. This HG has evenly notched greater coverts (no contrast between inners and outers) and obviously notched tertials (unnotched in LBBG and Caspian). They can be tricky.

Squared off tail corners shown very nicely here, Ian. Juvenile Sparrowhawk as you thought.
