I checked out the Penn Wood roost this evening and it was very disappointing (the Eurasian Sparrowhawk was patrolling again)
By 1530 hours, just 4 BRAMBLINGS had arrived (two males, two females), along with 63 Greenfinches, just 13 Chaffinches and 120 Redwings.
Nearby, 51 RED KITE flew in to roost, scrambling together on fir branches in the strong SW wind. Most interesting was the fact that Redwings were now utilising the kite roost with large numbers flighting in to land alongside them before disappearing into the dense areas closer to the trunk. I guess they use the kites as some form of safety - weird - particularly as Common Buzzards also share the roost.
