Family New World Blackbirds (Icteridae)


Slender-billed Grackle (Quiscalus palustris)


French: Quiscale de Mexico German: Schlankschnabelgrackel Spanish: Zanate picofino

Scaphidurus palustris


, 1827,

marshes and borders of lakes around City of Mexico




Marshes and headwaters of the R Lerma Santiago, and in Xochimilco, in the valley of Mexico.

First collected in 1822 and last recorded in 1910, presumably becoming extinct soon thereafter. Surprisingly poorly known, it is now thought to have nested in emergent aquatic vegetation in cultivated areas and, indeed, in towns. It also formed large flocks which damaged maize crops#R. Its demise is thought to have been due to the progressive draining of its marshland habitat for agricultural and urban development.
