From the author: 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 eggs, ejectmg them froln their nests almost immediately. As the Bronzed Cowbird expands its range and is studied in greater depth, more hosts will undoubtedly be record ed. Received 22 July 2004, accepted 19 March 2005.

From the author: We describe a photodocumented field observation in Sinaloa, Mexico, of a head-down (or "preening invitation") display performed by a male Bronzed Cowbird (Molothrus aeneus), which elicited both grooming and pecking responses from a female Great-tailed Grackle (Quiscalus mexicanus). Previously, such displays by parasitic cowbirds and responses by conspecific or various heterospecific bird species have been documented mainly under aviary conditions; most field observations have involved Brown-headed (M. ater) and Shiny (M. bonariensis) cowbirds. The function and evolutionary significance of such interspecific interactions remain elusive, but continued documentation of such occurrences may help elucidate their biological significance. Received 10 December 2004, accepted 2 August 2005.
