Genetic analyses have revolutionised our understanding of avian mating systems. However, the majority of such studies to date have focused on passerine species. Despite this taxonomic bias, extra-pair paternity (EPP) and conspecific brood parasi[...]

We analysed the temporal occurrence (day–night) and timing of nest predation events during incubation for six common passerine species breeding in austral Chaco, a temperate South American habitat. We recorded time of predation events and incuba[...]

Demographic parameters of wild animals are often closely associated with their foraging distribution and behaviour, and understanding these attributes can assist in identifying causes of population changes. The Indian Yellow-nosed Albatross (Tha[...]

Inland Australia is being transformed by invasive Cenchrus ciliaris (Buffel Grass) which is displacing native grasses. Zebra Finches (Taeniopygia guttata) forage on C. ciliaris seed but it is not known whether native grass seed is preferred. The[...]

We describe a new species of lapwing plover from the late Pliocene Kanunka Local Fauna of South Australia (3.6–2.6 mya).Vanellus liffyae sp. nov. is based on an almost complete coracoid, which is most similar in morphology to that of the Masked [...]

The invasive Argentine Ant, Linepithema humile, is known to prey on land bird chicks, but there are few reports of the ants’ impacts on breeding seabirds. We conducted a manipulative study using hen eggs to estimate the potential Argentine Ant r[...]

Olfactory nest recognition has been demonstrated in several avian species, including some gregarious Estrildid finches. In social species, which also form breeding colonies, olfactory nest recognition gives parents and fledglings the opportunity[...]

Theory predicts that, even within the same population, birds may vary their breeding investment with age. This may be due to an improvement in individual quality of old birds in body condition, foraging and in nesting experience. Birds commonly [...]

Male–male competition can cause less competitive males to pursue alternative mating strategies or defer reproduction until they are older. For species that display using non-bodily ornaments, male interference can also involve limiting rivals’ a[...]
