The effect of investigator perturbance has been traditionally considered detrimental for avian nesting success in terms of enhanced nest predation. This conclusion was however based on a taxonomically biased group of species and, thus, the study[...]

We studied the phylogenetic relationships of four duck genera endemic to South America: Brazilian teal Amazonetta brasiliensis, spectacled duck Speculanas specularis, crested duck Lophonetta specularioides, and four species of steamer ducks Tach[...]

The developmental rate of cuckoo embryos and their hatching size is greater than that of host species, which may require more nutrient resources in the egg and more intensive gas exchange during development. In the present study, we compared var[...]

Behavioural studies have led to the perception that lekking species experience a high male reproductive skew as a consequence of females' selective mate choice. In addition, observations suggest that females copulate only once and therefore poly[...]

Conspecific brood parasitism (CBP) occurs in over 200 species of birds. Efforts to detect CBP have relied on either observational criteria, or more recently, on molecular methods. While molecular approaches are powerful, they are expensive, time[...]

Eggshell colour patterns play a crucial role in avian host-parasite coevolution. In contrast to many experiments investigating general host egg discrimination abilities, studies testing where specific recognition cues are located on the eggshell[...]

Today's intensive farming practices are known to have affected farmland biodiversity negatively in many different ways. As far as birds are concerned, they are known to have suffered during both summer and winter. Relatively little is known abou[...]

Blood parasites are widespread in birds, several are pathogenic and may affect the fitness of their hosts, and their evolution. By reanalyzing recently published data I show that parts of the variation in prevalences of parasites in the blood of[...]

Blood parasites can negatively affect energetic condition, arrival date, and reproductive performance of breeding birds, yet their impact on migrating birds is poorly understood. We quantified haematozoan infection and examined its relationship [...]

The ability to identify distinct taxonomic groups of birds (species, subspecies, geographic races) can advance ecological research efforts by determining connectivity between the non-breeding and breeding grounds for migrant species, identifying[...]

Loop migration among birds is characterized by the spring route lying consistently west or east of the autumn route. The existence of loops has been explained by general wind conditions or seasonal differences in habitat distribution. Loop migra[...]

In sexually size-dimorphic species, brood sex composition may exert differential effects on sex-specific mortality. We investigated the sex-specific mortality and body condition in relation to brood sex composition in nestlings of the black-bill[...]
