Common cuckoo females remove more conspicuous eggs during parasitism [PDF]
Royal Society Open Science, 2021 Avian obligate brood parasites gain an advantage by removing the eggs of the cuckoos who have already visited the nest, which can increase the chances of survival for their offspring.

Egg rejection and egg recognition mechanisms in Oriental Reed Warblers
Avian Research, 2021 Background Nest parasitism by cuckoos (Cuculus spp.) results in enormous reproductive failure and forces hosts to evolve antiparasitic strategies, i.e., recognition of own eggs and rejection of cuckoo eggs.

Egg rejection and clutch phenotype variation in the plain prinia Prinia inornata
Journal of Avian Biology, 2016 Avian hosts of brood parasites can evolve anti‐parasitic defenses to recognize and reject foreign eggs from their nests. Theory predicts that higher inter‐clutch and lower intra‐clutch variation in egg appearance facilitates hosts to detect parasitic ...

Mobbing behaviour of hosts and non-hosts towards cuckoo Cuculus canorus of different sex
Acta EthologicaThe common cuckoo Cuculus canorus is an obligate brood parasite of many Eurasian bird species that exploit the parental care of their hosts. Although only females lay eggs in nests of passerine hosts, male and female cuckoos should cooperate to have a ...

Avian ResearchIn brood-parasitic Cuculus cuckoos, male vocalizations are species-specific and easily distinguishable, whereas female calls are remarkably similar across species, making species identification challenging.

Parental Provisioning in an Urban Apex Predator. [PDF]
Ecol EvolWe combine high‐definition webcams and citizen science to explore parental care in urban peregrine falcons from 30 locations across England between 2020 and 2023. By analysing detailed webcam footage, we quantified changes in prey type and delivery rates as chicks developed.

Proceedings of the Zoological Institute RASIn early June and July 2018 and 2019, during the reproduction period, we captured and equipped with satellite transmitters (5.3 g PinPoint GPS ARGOS 120) four males of the common cuckoo Cuculus canorus canorus (Linnaeus, 1758) in the vicinity of the city

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.

The Evolution of Predator Resemblance in Avian Brood Parasites
Frontiers in Ecology and Evolution, 2021 Predators have profound effects on prey behavior and some adult brood parasites use predator resemblance to exploit the antipredator defenses of their hosts.

Quintuple parasitism of a great reed warbler nest by common cuckoos
Ecology and Evolution, 2021 Multiple parasitism in obligate avian brood parasites occurs when several brood parasitic females lay their eggs in the nest of the same host. While multiple parasitism is common in the highly social, nonevicting cowbird species (Molothrus sp.), in which
