Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)
Ibis, Volume 168, Issue 1, Page 216-229, January 2026.Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...

The frontline of avian brood parasite–host coevolution
Animal Behaviour, 2012 The interactions between avian interspecific brood parasites and their hosts provide tractable and informative systems for investigating coevolution. Generally, these investigations have emphasized the egg and chick stages of the coevolutionary arms race; however, recent studies demonstrate that coevolution operates at all stages of the host nesting ...

Ibis, Volume 168, Issue 1, Page 79-94, January 2026.Many seabird species are in decline and population demographic models are important for revealing the causes and developing conservation strategies. Natal and breeding dispersal are key parameters of such models but can be challenging to estimate and may vary by sex.

BMC Evolutionary Biology, 2011 Background DNA-based studies have demonstrated that avian genetic mating systems vary widely, with many species deviating from long-assumed monogamy by practicing extra-pair paternity and conspecific brood parasitism.

AVIAN BROOD PARASITISM: INFORMATION USE AND VARIATION IN EGG-REJECTION BEHAVIOR [PDF]
Evolution, 2010 Hosts of avian brood parasites often vary in their response to parasitized clutches: they may eject one or several eggs, desert the nest, or accept all the eggs. Focusing on hosts exposed to single-egg parasitism by an evicting brood parasite, we construct an optimality model that includes all these behavioral options and use it to explore variation in

Combining personal with social information facilitates host defences and explains why cuckoos should be secretive. [PDF]
, 2016 Individuals often vary defences in response to local predation or parasitism risk. But how should they assess threat levels when it pays their enemies to hide? For common cuckoo hosts, assessing parasitism risk is challenging: cuckoo eggs are mimetic and

Ecology and Evolution, Volume 15, Issue 12, December 2025.While changes in both phenology and physiology under climate warming are known to influence infection dynamics, surprisingly few studies have explored their interactive effects. We extended the Ross‐MacDonald model for a vector‐borne disease to explore how projections of moderate and severe warming influence the emergence of a hypothetical vector‐borne

Filogenia y evolución de la conducta en los ictéridos [PDF]
, 2008 The evolution of selected behavioral characteristics in the family Icteridae is discussed in the light of the new DNA phylogeny. The woven pensile nest is found in only two of the main icterid clades, the caciques plus oropendolas (Cacicus and ...

Role of kinship in sociality of female eastern wild turkeys
Wildlife Society Bulletin, Volume 49, Issue S1, December 2025.We used a matrix of contact rates generated from high‐resolution global positioning system data to quantify interactions and contact rates based on genetic relatedness. We found that most females with genetic relatives in their winter flocks did not join social group prior to breeding that included those relatives. Our findings suggest that female wild

Altas Tasas de Parasitismo de Molothrus bonariensis sobre Pseudoleistes virescens Seleccionan Defensas Complementarias del Hospedador [PDF]
, 2013 Hosts of brood parasites may have not developed antiparasitic defenses either because host and parasite are recently sympatric or because costs of potential defenses outweigh their benefits.
