Loss of graded enemy recognition in a Whitehead population allopatric with brood-parasitic Long-tailed Cuckoos

open access: yesAvocetta, 2020
Many avian hosts of brood parasitic birds discriminate between various types of threats at the nest and may respond with categorically different, specifically anti-predatory or anti-parasitic behaviors. Alternatively, hosts may adjust their responses to

Coevolutionary interactions between farmers and mafia induce host acceptance of avian brood parasites [PDF]

open access: yesRoyal Society Open Science, 2016
Brood parasites exploit their host in order to increase their own fitness. Typically, this results in an arms race between parasite trickery and host defence. Thus, it is puzzling to observe hosts that accept parasitism without any resistance. The ‘mafia’

Fundamentals of Brood Parasitism

open access: yes
Brood parasitism is a reproductive strategy in which parasitic females secure parental care for their offspring by laying eggs in the nests of other individuals and relying on these unrelated foster parents to rear the parasitic young. Parasitic females may target hosts of their own species (conspecific brood parasitism) or of a different species ...

The Shiny Cowbird, Molothrus bonariensis (Gmelin, 1789) (Aves: Icteridae), at 2,800 m asl in Quito, Ecuador. [PDF]

open access: yes, 2016
The Shiny Cowbird, Molothrus bonariensis Gmelin, 1789, is a brood parasite of hundreds of small-bodied birds that is native to South American lowlands. Within the last 100 years this species has been expanding its range throughout the Caribbean, towards ...

Egg Rejection and Nest Sanitation in an Island Population of Barn Swallows (Hirundo rustica): Probability, Response Latency, and Sex Effects

open access: yesAnimals, 2022
Bird nests function as vessels for eggs and nestlings, and an environment for rearing offspring. However, foreign objects falling into bird nests and nestling eggshells may be harmful.

Sampling locality is more detectable than taxonomy or ecology in the gut microbiota of the brood-parasitic Brown-headed Cowbird (Molothrus ater) [PDF]

open access: yesPeerJ, 2014
Brown-headed Cowbirds (Molothrus ater) are the most widespread avian brood parasite in North America, laying their eggs in the nests of approximately 250 host species that raise the cowbird nestlings as their own.

Evolution: How Not to Detect a Brood Parasite [PDF]

open access: yesCurrent Biology, 2018
An elegant study on social parasitism in digger wasps quantifies the costs and benefits of kin recognition and shows that recognizing non-kin comes at a cost. This supports 'Crozier's paradox' of why kin recognition genes are unlikely to evolve when rare alleles are selected against.

Anti-brood Parasite Defences: The Role of Individual and Social Learning

open access: yes, 2017
In this chapter, we consider the ways in which learning is involved in the antibrood parasitism defences that hosts deploy across the nesting cycle. Brood parasitism varies in space and through time, and hosts have accordingly evolved plastic defences

Ecological uncertainty favours the diversification of host use in avian brood parasites

open access: yesNature Communications, 2020
Nearly 17% of all bird species are hosts to obligate brood parasites like the common cuckoo. Antonson et al. show that parasite species hedge their reproductive bets by outsourcing parental care to a greater variety of host species when the rearing ...

Reproduction of Varroa destructor in sealed worker bee brood cells of Apis mellifera carnica and Apis mellifera syriaca in Jordan [PDF]

open access: yes, 2008
The reproduction of the honey bee mite, Varroa destructor in sealed worker bee brood cells represents an important factor for the population development of this parasite in honey bee colonies.
