Understanding the Loss of Maternal Care in Avian Brood Parasites Using Preoptic Area Transcriptome Comparisons in Brood Parasitic and Non-parasitic Blackbirds

G3: Genes, Genomes, Genetics, 2019
Parental care is critical for offspring survival in many species. However, parental behaviors have been lost in roughly 1% of avian species known as the obligate brood parasites.

A game-theoretic model of interspecific brood parasitism with sequential decisions [PDF]

, 2008
The interaction between hosts and parasites in bird populations has been studied extensively. This paper uses game-theoretic methods to model this interaction.

A review of the cues used for rejecting foreign eggs from the nest by the Eurasian blackbird (Turdus merula)

Ecology and Evolution, 2022
Avian brood parasitism is reproductively costly for hosts and selects for cognitive features enabling anti‐parasitic resistance at multiple stages of the host's breeding cycle.

A Meta-Analysis of Avian Egg Traits Cueing Egg-Rejection Defenses Against Brood Parasitism

Frontiers in Ecology and Evolution, 2021
The capability of hosts to reject the odd egg from their nest is one of the key defenses against avian brood parasitism. Considerable research effort has been devoted to exploring which phenotypic traits of eggshells facilitate to cue the recognition of ...

Variation in plasma oxidative status and testosterone level in relation to egg-eviction effort and age of brood-parasitic common cuckoo nestlings [PDF]

, 2012
To avoid competition for parental care, brood-parasitic Common Cuckoo (Cuculus canorus) nestlings evict all of the host's eggs and nestlings within a few days after hatching.

LAYING PLASTICITY IN AN AVIAN BROOD PARASITE [PDF]

The Auk, 2005
AbstractFemales of some bird species “steal“ the parental care of other breeding individuals by laying eggs parasitically in their nests. In most populations, conspecific brood parasites lay parasitically before laying in their own nests. By contrast, in a young and expanding Common Moorhen (Gallinula chloropus) population, 17.4% (n = 8) of brood ...

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

Avocetta, 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

Lichens in the nests of European starling Sturnus vulgaris serve a mate attraction rather than insecticidal function [PDF]

, 2018
The European starling Sturnus vulgaris is a hole-nesting bird in which the male builds a voluminous nest using a wide variety of materials such as twigs, grass, leaves, feathers, and lichens.

Naïve hosts of avian brood parasites accept foreign eggs, whereas older hosts fine-tune foreign egg discrimination during laying [PDF]

, 2014
BACKGROUND: Many potential hosts of social parasites recognize and reject foreign intruders, and reduce or altogether escape the negative impacts of parasitism.

Model eggs fail to detect egg recognition in host populations after brood parasitism is relaxed

Frontiers in Zoology, 2020
Background Obligate brood parasites exert strong selective pressure on target hosts. In response, hosts typically evolve anti-parasitism strategies, of which egg recognition is one of the most efficient.
