Brood parasitism and host-parasite relationships: Cuckoos adapt …
Such an adaptive feature of brood parasitism in cuckoos, i.e., the egg incubation beginning while still in the mother's body, is crucial for reducing I in the host nest; however, it is not always feasible in practice.
When parenting goes cuckoo - Science News Explores
Apr 18, 2019 · The adult great spotted cuckoo, a brood parasite, leaves its eggs in carrion-crow nests. Here, a cuckoo chick (right) grows up alongside a crow chick (left).
Brood parasitism - Wikipedia
Most avian brood parasites have very short egg incubation periods and rapid nestling growth. In many brood parasites, such as cuckoos and honeyguides, this short egg incubation period is due to internal incubation periods up to 24 hours longer in cuckoos than hosts.
Brood Parasitism - Stanford University
Our cuckoos usually build nests of their own and rear their own young. Only about 40 percent of cuckoo species worldwide are brood parasites, the rest care for their own eggs and young. Brood parasitism is much less common in other groups of birds.
Coevolution with hosts underpins speciation in brood-parasitic …
May 30, 2024 · Our study provides evidence that coevolutionary interactions between brood parasites and their hosts can drive speciation of the parasites, even in sympatry. This contrasts with a different mode of sympatric speciation that occurs in a less virulent brood parasite .
Importance of cooperation: How host nest defenses effectively …
Apr 21, 2023 · As the frontline defense against avian brood parasitism, nest defense is important in reducing nest parasitism and increasing host fitness. However, systematic studies on its effectiveness (i.e., on whether it successfully prevents cuckoo parasitism) are scarce.
Cuckoo Brood Parasitism - SpringerLink
Dec 11, 2019 · Cuckoos (Cuculidae spp.) mitigate the energy expenditure associated with rearing hatchlings through obligate brood parasitism in which the female lays her eggs in the nest of another specific host bird species (i.e., magpies, weaver …
Brood parasitism and host-parasite relationships: Cuckoos adapt …
Aug 26, 2024 · The phenomenon of cuckoos' brood parasitism is well known and can be investigated using applied mathematical techniques. Among adaptive features of this phenomenon are certain egg parameters that ensure their shortened incubation period (I) and thus the successful survival of their offspring.
Brood parasitism risk drives birds to breed near humans - Cell Press
Mar 27, 2023 · Our study thus suggests that the risk of brood parasitism might be a driver explaining why some birds settle near humans. One may argue that redstarts choose proximity to buildings in response to cuckoo parasitism simply because buildings provide …
The tale of the parasitic cuckoos - Nature
Apr 18, 2002 · There are 53 species, called brood parasites, that lay their eggs in the nests of other bird species; the 83 other cuckoo species raise their young themselves, although some of them may...
