For avian brood parasites in which individual females are host-specialists, the arms race between hosts and parasites has favored egg color polymorphism in the parasite, with female lineages laying mimetic eggs that resemble those of the host species they parasitize.

AbstractBrood parasitic birds such as cowbirds (Molothrusspp., Icteridae) lay their eggs in the nests of other species, abandoning them to be incubated and raised by the hosts. Lack of investment in parental care results in high annual fecundities of female parasitic birds. Brood parasites lay eggs in series or clutches, separated by gaps or non‐laying

Parasitismo de cría: nuevos eventos para el vaquero brilloso Molothrus bonariensis
Revista Catalana d'OrnitologiaBrood parasites lay their eggs in the nests of other species, thereby imposing on them the cost of parental care. In the Neotropics, the Shiny Cowbird Molothrus bonariensis is an obligate, generalist and opportunistic brood parasite with a wide and expanding range.

ABSTRACT The social systems and space use of birds depend on the distribution and abundance of resources. Brood-parasitic cowbirds (Molothrus spp.) exhibit a unique pattern of changing social behavior on a daily cycle. Female Brown-headed Cowbirds (M.

Records of the Shiny Cowbird (<em>Molothrus bonariensis</em>) in Jamaica
Journal of Caribbean Ornithology, 2019Abstract: The Shiny Cowbird (Molothrus bonariensis) is a brood parasite native to South America that has spread across the Caribbean archipelago and North America. The species likely reached Puerto Rico before 1955, the Dominican Republic in 1972, Cuba in 1982, the Bahamas in 1984, and the Florida Keys in 1985.

Abstract I present the second record of Shiny Cowbird (Molothrus bonariensis) parasitism of the Black-chinned Siskin (Carduelis barbata). The last recorded observation was in 1929. This also represents the northernmost nesting record of the Black-chinned Siskin.
