Mating systems in birds
B Kempenaers - Current Biology, 2022 - cell.com
Most vertebrates, including all mammals and birds, are sexually reproducing organisms. The
implication of sexual reproduction is that an adult bird exists because a male transferred …

The coevolutionary biology of brood parasitism: a call for integration
Obligate brood-parasitic cheats have fascinated natural historians since ancient times.
Passing on the costs of parental care to others occurs widely in birds, insects and fish, and …

Coevolutionary arms race between a specialist brood parasite, the Screaming Cowbird, and its host, the Grayish Baywing
Interspecific brood parasites exploit the parental care of host species. This exploitation
entails fitness costs for the hosts, which favor the evolution of antiparasitic defenses. Host …

[HTML][HTML] Male common cuckoos use a three-note variant of their “cu-coo” call for duetting with conspecific females
Duetting is a coordinated form of acoustic communication with participants uttering calls or
songs simultaneously and/or sequentially. Duetting is often observed in pair-bonded …

Males and females of a polygamous songbird respond differently to mating opportunities
Parents are expected to make fine-tuned decisions by weighing the benefits of providing
care to increase offspring survival against that of deserting to pursue future mating …

Greater opportunities for sexual selection in male than in female obligate brood parasitic birds
Females are expected to have evolved to be more discriminatory in mate choice than males
as a result of greater reproductive investment into larger gametes (eggs vs. sperm). In turn …

Genetic patterns of repeat and multiple parasitism by screaming cowbirds, a specialist brood parasite
Avian brood parasites lay their eggs in the nests of other species, leaving the hosts to care
for the parasitic offspring. The bookkee** hypothesis predicts that, in order to reduce …

Molecular sibship reconstruction reveals a promiscuous mating system in brood parasitic little bronze-cuckoos (Chalcites minutillus)
In theory, emancipation from parental care is expected to favor promiscuous mating systems.
However, in avian brood parasites, monogamy is surprisingly widespread, and it has been …
