Behavioural Transitions in the Reproductive Cycle of Barbary Doves (Streptopelia Risoria L.)

摘要: The pre-oviposition phase of the reproductive cycle male Barbary dove is characterized by a series behavioural transitions which lead to construction nest and incubation behaviour. present study provides detailed account early courtship 14 pairs female doves, given continuous access one another, analyses temporal relationships between in courtship. Male aggressive courtship, consisting chasing bowing, declines rapidly within first day pairing virtually disappears second or third day. In contrast, substantial levels soliciting, nest-orientated activity, continue be displayed until fifth pairing. There is, therefore, differential rate decline patterns such that time spent soliciting increases relative A succession further takes place behaviour male. Thus, begins display sitting at future site on This reaches peak continues seventh pairing; period average similar latency oviposition (median, 7.0 days). also gather nesting material this oviposition. are accompanied comparable not with those male, pairing, fourth Female replaced sitting, sixth build interaction accepts greatest number pieces two days before appears influence both terms subsequent development. Thus duration bowing shown during initial positively correlated Similarly, termination directly related onset These correlations support view aggressiveness may delay
