Brood Parasitism of the Shiny Cowbird, Molothrus bonariensis, on the Brown-and-Yellow Marshbird, Pseudoleistes virescens [PDF]
Condor, 1994 AbstractObligate avian brood parasites can be host specialists or host generalists. In turn, individual females within generalist brood parasites may themselves be host specialists or generalists. The shiny cowbirdMolothrus bonariensisis an extreme generalist, but little is known about individual female host fidelity.

First Records of the Shiny Cowbird (Molothrus bonariensis) in the Bahama Archipelago
Auk, 1995The spread of the Shiny Cowbird (Molothrus bonariensis) northward through the Caribbean during the past 93 years has been well documented (Post and Wiley 1977, Cruz et al. 1985). The species reached mainland Puerto Rico in 1955 (Grayce 1957), the Dominican Republic in 1973 (Bond 1973), and Cuba in 1982 (Garrido 1984). It first appeared in North America

History of Shiny Cowbird Molothrus bonariensis brood parasitism in Trinidad and Tobago
Ibis, 1995In attempting to evaluate the evolutionary stability of the reproductive strategies of an avian brood parasite, it is important to know whether or not the observed levels of parasitism on host species have changed through time and whether or not new host species are being used in the region under study.

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

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.

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.

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.
