How strong are eggs of the common cuckoo Cuculus canorus? [PDF]
Journal of Vertebrate Biology, 2020 The common cuckoo Cuculus canorus is an obligate brood parasite that lays its eggs in the nests of small passerines. It has long been hypothesized that cuckoo eggs should be structurally stronger than host eggs or those of non-parasitic cuckoos to reduce chances of breakage during laying, to prevent accidental damage during incubation and/or to hinder ...

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.

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 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 ...

Frontiers in Ecology and Evolution, 2021 Cuckoo nest parasites lay eggs in host nests and thereby transfer all reproduction costs to the hosts. This greatly reduces host fitness. Parasitism has selected for the evolution of anti-parasitic strategies in hosts, including nest defense. The dynamic

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.

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

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.

Remote Sensing in Ecology and Conservation, EarlyView.In this study, we developed AnuraSearch, an open‐source classifier for 11 Ukrainian amphibian species, by repurposing the avian BirdNET algorithm via transfer learning to process over 18,000 h of autonomous acoustic recordings. Although the model demonstrated high precision and successfully reconstructed detailed seasonal and diel vocal activity ...
