Time constraint on food choice in provisioning blue tits, Parus caeruleus: the relationship between feeding rate and prey size
F Grieco - Animal Behaviour, 2002 - Elsevier
Previous work on food-provisioning behaviour in blue tits suggested that the parents could
gather larger prey items only by making longer foraging excursions, for example, by being …

Alternation of nest visits varies with experimentally manipulated workload in brood-provisioning great tits
Highlights•We tested the effect of parental workload on alternation of nest visits.•A reduction
in workload caused a decrease in parental provisioning rate.•Alternation of the nest visits …

How different provisioning strategies result in equal rates of food delivery: an experimental study of blue tits Parus caeruleus
F Grieco - Journal of Avian Biology, 2002 - Wiley Online Library
Food provisioning in birds requires a considerable amount of time and usually has to be
traded‐off against other parental and non‐parental activities. I investigated experimentally …

Parental sex differences in food allocation to junior brood members as mediated by prey size
KL Wiebe, T Slagsvold - Ethology, 2009 - Wiley Online Library
Individual offspring within a brood may receive different amounts of provisioning from the
male and female parents. Some hypotheses suggest that this bias is the result of an active …
