For three of four mated male pigeons, intrusion of a still, two‐dimensional image of a conspecific into the reproductive situation initiated aggressive behavior over months of daily testing with little habituation. There was a transient increase in aggressive contacts against the head of the target within two days prior to or following the occurrence of the second egg. Such an increase did not occur with extended daily testing of the male alone and was more closely synchronized to egg laying than time since the introduction of the female. The results are consistent with previous studies of reproductive and schedule‐induced aggression in birds.
