Peregrine food

A dull wet day here - much warmer and sunnier in the Uists which must be a bit of a record.
Pottered about moving things around inside and came across these which Tricia had picked up in Eton below the roosting Peregrine of Monday's blip. No prizes for seeing how high Ring-necked Parakeets feature in its diet but can't quite work out the white and pink feathers. Flamingoes are not too common in Berkshire!
