Jackdaws (Corvus monedula). Both juveniles of the year, from different nests. Grey mutation, aberrant, bird right, adopting a begging to be fed posture, with darker slightly older bird left, about to plunge pre-ingested food into the bill of the other. Behaviour, not learnt, but an instinctive, prompted response to begging posture, being the coloured gaping bill of the other.
