Video evidence that cuckoos farm their hosts by ejecting nestlings

Ecology and Evolution
When host nests are scarce, avian brood parasites would benefit from behaviours that increase the availability of suitable nests. Several studies reported ejection of host nestlings from nests by brood parasites; however, whether brood parasites do so to

Selected Elements of Animated Nature Associated with the Birth of Jesus in the Bulgarian Oral Culture and Apocryphal Narratives [PDF]

, 2014
Translated by Katarzyna GucioThe article attempts to extract textual and extratextual planes on which representatives of fauna made their mark in the folklore of the South Slavs, mainly Bulgarians; in their oral literature, rituals, and beliefs ...

Can nest design hinder brood parasitism success?

Journal of Avian Biology
Avian nest design varies depending on environmental factors but may also be influenced by between‐species interactions. In the brood parasitism context, hosts may evolve nest architectures that may limit parasite access to the nest cup, reduce parasite ...

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 ...

Image compression based on vector quantization using cuckoo search optimization technique

Ain Shams Engineering Journal, 2018
Most common vector quantization (VQ) is Linde Buzo Gray (LBG), that designs a local optimal codebook for image compression. Recently firefly algorithm (FA), particle swarm optimization (PSO) and Honey bee mating optimization (HBMO) were designed which ...

Recurrence, fidelity and proximity to previously visited sites throughout the annual cycle in a trans‐Saharan migrant, the common cuckoo

Journal of Avian Biology
Most migratory birds return every year to the same breeding sites and some species show a similarly high fidelity to wintering grounds as well. Fidelity to stopover sites during migration has been much less studied and is usually found to be lower. Here,

Brood parasitism and host-parasite relationships: Cuckoos adapt to reduce the time of hatching ahead of host nestlings by increasing egg thickness

International Journal for Parasitology: Parasites and Wildlife
The phenomenon of cuckoos’ brood parasitism is well known and can be investigated using applied mathematical techniques. Among adaptive features of this phenomenon are certain egg parameters that ensure their shortened incubation period (I) and thus the ...
