Shiny cowbird

It is a bird associated with open woodland and cultivation. The male’s song is a purr and whistle, purr purr purrte-tseeeee. The male’s call is a sharp whistled tsee-tsee, but the female makes a harsh rattle.

The Shiny cowbird is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The Shiny Cowbird, Molothrus bonariensis, is a passerine bird in the New World family Icteridae. It breeds in most of South America apart from the most dense jungles, mountains and deserts (although spreading into these habitats as they are modified by humans), the coldest southernmost regions (e.g. Tierra del Fuego), and on Trinidad and Tobago. It has relatively recently colonised Chile and many Caribbean islands, and has reached the USA, where it is probably breeding in southern Florida. More

* Shiny Cowbird, Molothrus bonariensis * Brown-headed Cowbird, Molothrus ater The non-brood parasitic Bay-winged Cowbird was formerly placed in this genus; it is now Agelaioides badius. These birds feed on insects, including the large numbers that may be stirred up by cattle. In order for the birds to remain mobile and stay with the herd, they have adapted by laying their eggs in other birds' nests. More

Extermination of the Shiny Cowbird within the tiny range of the Pale-headed Brush-finch has resulted in a population increase in this critically endangered species. The male Shiny Cowbird is 20.3 cm long, weighs 45 g and is all black with an iridescent purple-blue gloss. The smaller female is 19 cm long and weighs 31 g. Her plumage is dark brown, paler on the underparts. She can be distinguished from the female Brown-headed Cowbird by her longer, finer bill, pale superciilium and stronger face pattern. More

Georgia to try to locate the Shiny Cowbird that he reported seeing earlier that morning on GABO . I arrived at approximately 2:00 pm and met Gene outside his greenhouse. As he was telling me where to try looking, a small flock of Brown-headed Cowbirds landed in a nearby tree. Looking through binoculars, one of them appeared to be all black, including the head. I went back to my truck to get my scope and as I did so the bird moved to a closer tree. More

SHINY COWBIRD Molothrus bonariensis Decked out in glossy black plumage, the Shiny Cowbird looks like an undertaker, and if an egg-carrying female is in your territory then she might as well be an undertaker, for her presence likely signals the end of your own brood and the beginning of a hard labour sentence to raise her baby - the cowbird is a brood parasite (she lays her eggs in other birds nests, in the same way as the European Cuckoo Cuculus canorus).

The Shiny Cowbird (Molothrus bonariensis) of South America, Panama, and the West Indies is an obligate brood parasite known to have used 176 species of birds as hosts. This study documents wide variability in the quality of real and potential hosts in terms of response to eggs, nestling diet, and nest survivorship. The eggs of the parasite are either spotted or immaculate in eastern Argentina and neighboring parts of Uruguay and Brazil. More

A comparative study of Shiny Cowbird parasitism in two large hosts: Chalk-browed mockingbird and Rufous-bellied thrush Sackmann P.; Reboreda JC. Abstract It is usually accepted that generalist brood parasites should avoid using hosts larger than themselves because host chicks may outcompete parasite chicks for food. We studied the interactions between Shiny Cowbird (Molothrus bonariensis)and two common hosts that are considerably larger than the parasite,Chalk-browed Mockingbird (Mimus saturninus )and Rufous-bellied Thrush (Turdus rufiventris ).

America, and the Shiny Cowbird will lay eggs in the nests of hundreds of different species. Some Brown-headed Cowbirds apparently specialize in parasitizing particular host species. Cowbirds scan for nests in which to lay their eggs. They tend to search near their foraging areas—in agricultural areas where there are abundant seeds, urban areas, and grasslands bordering forests. Thus, host species' nests in these areas are parasitized more often than nests in other habitats. More
