Nest architecture influences host use by avian brood parasites and is shaped by coevolutionary dynamics

open access: yes, 2023
Brood (social) parasites and their hosts exhibit a wide range of adaptations and counter-adaptations as part of their ongoing coevolutionary arms races. Obligate avian brood parasites are expected to use potential host species with more easily accessible

Development and behavior of Plaintive Cuckoo (Cacomantis merulinus) nestlings and their Common Tailorbird (Orthotomus sutorius) hosts

open access: yesAvian Research, 2019
Background Our knowledge of avian brood parasitism is primarily based on studies of a few selected species. Recently, researchers have targeted a wider range of host–parasite systems, which has allowed further evaluation of hypotheses derived from well ...

Acoustic Mimicry of Begging Calls and Its Geographical Differentiation in Nestling Common Cuckoos Toward Oriental Reed Warblers 大杜鹃雏鸟对东方大苇莺乞食鸣叫声的声学模仿及其地理分化

open access: yesWildlife Letters, EarlyView.
Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...

Dataset from Host density predicts the probability of parasitism by avian brood parasites

open access: yes, 2018
The spatial distribution of hosts can be a determining factor in the reproductive success of parasites. Highly aggregated hosts may offer more opportunities for reproduction but can have better defences than isolated hosts.

No evidence of host-specific egg mimicry in Asian koels.

open access: yesPLoS ONE, 2021
Avian brood parasitism is costly for the host, in many cases leading to the evolution of defenses like discrimination of parasitic eggs. The parasite, in turn, may evolve mimetic eggs as a counter-adaptation to host egg rejection.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Supplementary methods and figures from Host density predicts the probability of parasitism by avian brood parasites

open access: yes, 2018
The spatial distribution of hosts can be a determining factor in the reproductive success of parasites. Highly aggregated hosts may offer more opportunities for reproduction but can have better defences than isolated hosts.

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

open access: yesIntegrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Seasonal increase in nest defense, but not egg rejection, in a cuckoo host

open access: yesAvian Research
The interactions between avian brood parasites and their hosts provide an informative and easy-to-handle system for studying coevolution. Avian brood parasitism reduces the reproductive success of hosts, and thus, hosts have evolved anti-parasitic ...

Egg Rejection and Nest Sanitation in an Island Population of Barn Swallows (Hirundo rustica): Probability, Response Latency, and Sex Effects

open access: yesAnimals, 2022
Bird nests function as vessels for eggs and nestlings, and an environment for rearing offspring. However, foreign objects falling into bird nests and nestling eggshells may be harmful.
