Really disappointing weekend

On Saturday 10th October, I was hoping to twitch the Lammergeier in Lincolnshire but not sure exactly where to go I opted to leave it to Sunday and travel with John H, it showed really well so that was a big mistake that I bitterly regret as the bird had gone Saturday. Instead, I travelled to Southwold campsite and saw the Radde's Warbler briefly in the low right- hand branch of a pine tree for all of 5 seconds at 10.40am that's all I saw and no pics, which was very disappointing. Twitchers standing in the area where it frequented didn't help. A Redpoll flew over calling too. Little seen on Sunday.
