Observations of a Jackdaw attempting to feed a pigeon fledgling. - T. Hetmanski.

The Jackdaw can be a serious nest predator of Feral Pigeon colonies located in the towers and attics of urban buildings if these areas are easily accessible. Jackdaws were responsible for the destruction of about 6 % of eggs and 18 % of nestlings in one of the five colonies of Feral Pigeon in S³upsk (NW Poland) studied over 19982001 years. In 2000, I observed a Jackdaw attempting to feed a Feral Pigeon fledgling. As full documentation of the factors leading to such behaviour is lacking, I propose the hypothesis that this was the result of misdirected parental behaviour or misdirected sexual behaviour.
