We report the first record of Bronzed Cowbird (Molothrus aeneus) parasitism on the Great-tailed Grackle (Quiscalus mexicanus'), which represents the 96th known host for this cowbird species. The record is based on a parasitized clutch, collected from Sinaloa, Mexico, in the collection at the Western Foundation of Vertebrate Zoology. The clutch contained four grackle eggs and one Bronzed Cowbird egg. This record is unusual because the Great tailed Grackle is extremely intolerant of foreign e...

Laying time of the bronzed cowbird.
Wilson Bulletin ; Avian brood parasites that are surreptitious when parasitizing nests may avoid detection by their hosts. Indeed, they often lay their eggs in a matter of seconds; Sealy and coworkers (1995) found this behavior to be unique to the diverse groups of brood parasites. The parasitic Brown-headed Cowbird
First Record of Bronzed Cowbird (Molothrus aeneus) Parasitism of the Common Bush-tanager (Chlorospingus ophthalmicus).(SHORT COMMUNICATIONS)
The Wilson Journal of Ornithology ; Brood parasitic cowbirds (Molothrus spp.) differ greatly in the number of hosts. Bronzed (M. aeneus), Brown-headed (M. ater), Shiny (M. bonariensis), and Screaming (M. rufoaxillaris) cowbirds are reported to have parasitized between 10 and 200 hosts (Fraga 2005, Ortega et al. 2005, Peer et al.

First record of shiny cowbird (Molothrus bonariensis) in Yucatan, Mexico.
Wilson Bulletin ; The Shiny Cowbird (Molothrus bonariensis) has rapidly expanded its range since the turn of the century, island hopping from Trinidad and Tobago north through the Lesser Antilles, and west through the Greater Antilles (Post and Wiley 1977, Post et al. 1993). The species was first recorded in Cuba in
