Individual variation in parental tradeoffs between the number and size of offspring at the pre- and post-natal stages

期刊: IBIS, 2020; 162 (4)

Life-history theory predicts that parents refer to the resources they hold to determine their breeding strategy. In multi-brooded species, it is hypot......

Migration timing influences the responses of birds to food shortage at their refuelling site

期刊: IBIS, 2019; 161 (4)

Because migration is highly time-constrained and migration timing varies among individuals, the responses of migrants to food shortage at a refuelling......

Effects of extra-pair paternity and maternity on the provisioning strategies of the Azure-winged Magpie Cyanopica cyanus

期刊: IBIS, 0; ()

Altricial birds show enormous intraspecific diversity in their provisioning strategies, in terms of both the provisioning rate and the amount of food ......

Field study of the relationship between personality and reproductive strategy in the White-collared Blackbird Turdus albocinctus

期刊: IBIS, 0; ()

The discovery of personality traits in animal populations may help to explain individual variation in breeding strategies. In the White-collared Black......

Does snowmelt constrain spring migration progression in sympatric wintering Arctic-nesting geese? Results from a Far East Asia telemetry study

期刊: IBIS, 0; ()

Telemetry data from sympatric Eastern Tundra Bean Geese Anser serrirostris captured on their winter quarters in the Yangtze River Floodplain, China, t......

Genetic evidence of hybridization of the world's most endangered tern, the Chinese Crested Tern Thalasseus bernsteini

期刊: IBIS, 2018; 160 (4)

We collected multi-locus data to test whether hybridization has occurred between a critically endangered waterbird, the Chinese Crested Tern Thalasseu......

Azure-winged Magpies Cyanopica cyanus trade off reproductive success and parental care by establishing a size hierarchy among nestlings

期刊: IBIS, 2018; 160 (4)

It is common in birds that the sizes of nestlings vary greatly when multiple young are produced in one nest. However, the methods used by parents to e......

Seasonal variation in food availability influences the breeding strategy of White-collared Blackbirds Turdus albocinctus on the Tibetan Plateau

期刊: IBIS, 2017; 159 (4)

Parent birds show a continuous spectrum of breeding strategies, ranging from a low-fecundity and high-survival pattern to a high-fecundity, low-surviv......

Phylogenetic relationships, song and distribution of the endangered Rufous-headed Robin Larvivora ruficeps

期刊: IBIS, 2017; 159 (1)

The Rufous-headed Robin Larvivora ruficeps is one of the world's rarest and least known birds. We summarize the known records since it was first descr......
