Communications Biology, 2023 In host-symbiont systems, interspecific transmissions create opportunities for host switches, potentially leading to cophylogenetic incongruence. In contrast, conspecific transmissions often result in high host specificity and congruent cophylogenies. In

Preferential Begging Responses of Shiny Cowbirds to the Conspecific Chatter Call
Frontiers in Ecology and Evolution, 2022 Avian brood parasites lay their eggs into the nests of other species, which incubate them and raise the chicks until their independence. Despite living their early weeks of life surrounded by heterospecifics, young brood parasites have the ability to ...

Ranging behavior of female and male Shiny Cowbirds and Screaming Cowbirds while searching for host nests [PDF]
, 2014 Pusimos a prueba la hipótesis que los tordos parásitos de cría buscan y localizan nidos de hospedadores dentro de un área relativamente constante, ya que esto facilitaría el monitoreo de nidos a través del tiempo y la sincronización del parasitismo con ...

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.
