Given that both sexes of most parrots learn new vocalizations throughout life and produce
them in diverse social contexts, whereas few songbird species combine all these traits, why …

Parrots (Psittaciformes) are a well-studied, diverse group of birds distributed mainly in
tropical and subtropical regions. Today, one-third of their species face extinction, mainly due …

We present the first data on the breeding biology of wild Burrowing Parrots (Cyanoliseus
patagonus). We studied chick growth and breeding success at the largest colony of the …

Parrots of the Wild explores recent scientific discoveries and what they reveal about the lives
of wild parrots, which are among the most intelligent and rarest of birds. Catherine A. Toft …

The monk parakeet (Myiopsitta monachus) is a successful invasive species that does not
exhibit life history traits typically associated with colonizing species (eg, high reproductive …

Sex‐biased mortality can lead to altered adult sex ratios (ASR s), which may in turn lead to
harassment and lower fitness of the rarer sex and changes in the mating system. Female …

We here describe the largest colony of Burrowing Parrots (Cyanoliseus patagonus), located
in Patagonia, Argentina. Counts during the 2001–02 breeding season showed that the …

Hummingbirds have evolved to learn song from conspecifics independently of other bird
clades that show this behaviour, such as parrots and oscine passerines. Little is known …

Haematology and plasma biochemistry values are useful tools for ecological research. They
have been used to investigate the physiological state and the adaptation of individuals to …

Background While the gene flow in some organisms is strongly affected by physical barriers
and geographical distance, other highly mobile species are able to overcome such …
