Analysis of Egg Variation and Foreign Egg Rejection in Rüppell’s Weaver (Ploceus galbula)
Frontiers in Ecology and Evolution, 2021 Egg appearance is notable for its variation and as a source of recognition cues in bird species that are subject to egg-mimicking brood parasitism. Here I analyze the egg appearance of an East African weaverbird species that has variable eggs and is a ...

The evolution of host specialisation in avian brood parasites
Ecology Letters, 2016 AbstractTraditional ecological theory predicts that specialisation can promote speciation; hence, recently derived species are specialists. However, an alternative view is that new species have broad niches, which become narrower and specialised over time.

Frontiers in Ecology and Evolution, 2021 Hosts of brood parasitic cuckoos often employ mobbing attacks to defend their nests and, when mobbing is costly, hosts are predicted to adjust their mobbing to match parasitism risk. While evidence exists for fine-tuned plasticity, it remains unclear why

The Brown-headed Cowbird: North America’s avian brood parasite [PDF]
Chinese Birds, 2013 There are five species of parasitic cowbirds ( Molothrus) and the Brown-headed Cowbird (M. ater) is the only widespread species in North America. The Brown-headed Cowbird is a host generalist and is typically found in open habitats and forest edges.

Cowbirds use conspecific social information to detect host nests in the wild
Ibis, Volume 168, Issue 2, Page 799-804, April 2026.Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

Comparing vocal structures of the parasitic and nonparasitic groups in Cuculinae
Avian Research, 2017 Background Avian brood parasitism is a breeding strategy in which brood parasites lay their eggs in the nest of other species. This behavior is closely related to aspects of the biological evolution of the parasitic species such as reduced female body ...

A novel method to collect sperm from brood parasitic cuckoos: Urodeum stimulation (UroS) method
Avian Research, 2023 Sperm competition has been studied in numerous species as a representative example of postcopulatory sexual selection, where sampling sperm from male is the most basic and important step.

Bridging the gap: improving methodologies for future avian microbiome research
Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Recent advances in the field of wild avian microbiome research have significantly deepened our understanding of the eco‐evolutionary dynamics of bird–microbe interactions. Consequently, the field is now approaching a pivotal moment in uncovering the ultimate factors shaping avian microbiome structure, especially in relation to birds' ecological ...
