a late Red-backed Shrike in Lincolnshire

we did 10 miles on the Lincs coast yesterday and found a total of no scarce birds just a handful of Woodcocks and three Chiffchaffs so resorted to taking in the juvenile Red-backed Shrike at Sea View Farm -- a nice bird and notably late for this species -- it was catching flying insects in the air as well as insects on the ground and this ejected pellet looks to have plenty of beetle cases in it -- when it coughed it up bits flew in all directions
