Visual search for cryptic stimuli in pigeons: implications for the search image and search rate hypotheses
Article Abstract:
Detection of cryptic 'prey' in pigeons improves with the increase in the frequency of target presentation. Three studies conducted on cryptic prey detection in pigeons disprove the search rate hypothesis and confirms the interference prediction of the search-image hypothesis. An operant discrimination procedure and complex computer-generated stimuli were used in the experiments. Improved detection of cryptic prey does not improve with a reduction in the search rate.

Parent-squab interaction during the transition from dependent to independent feeding in the ring dove, Streptopelia risoria
Article Abstract:
Squabs showed pecking and begging actions whereas retracting and pecking was shown by parent doves at 12-17 days in an analysis of the parent-squab activity during the transition phase from dependent to independent feeding in ring doves. Negative correlation between regurgitative feeding and squab pecking is observed. Influence of pecking by the parents in eliciting independent feeding behavior in squabs is frequently observed.

Avian olfactory navigation: Its empirical foundation and conceptual state
Article Abstract:
Empirical evidence to understand the role of atmospheric trace gases perceived by olfaction that help pigeons navigate home is presented. Experiments and conclusion for the above are given but the olfactory navigation is still at its conceptual state.
