After a busy day doing things other than birding...I had a look at WW to find.
6:40-Nero feeding inside the nest box, not sure what it was...smaller than a crow (and no black feathers) larger than a sparrow ! Appears to be a whole bird
6:50- A sister shows up and perches on the lower camera.
6:54-Sister catches some ZZZZZ's
After 20 min Nero is still eating...and sister is still watching
7:03-Sister is into to the nest box looking for left overs
Nero leaves the meal and it appears to be Annie that has come for left-overs
7:21-Annie drags the remains up out of the nest box and leaves it on the ledge
With the shadows and low light it's even hard to see the color bands ( yellow/silver)...if I'm wrong TPC will correct me !
Just my observations this evening !
Cheers !
