Résumé :	ABSTRACT Many migratory grassland passerines complete their annual life cycle within the United States and investigations into wintering ecology of these species are scarce, particularly in ecoregions where habitat quality is considered to be compromised, such as the coastal prairie of Texas. During 2008?2010, we investigated wintering grassland bird ecology as related to coastal prairie composition and management practices on the mid-upper Texas coast. To quantify grassland bird composition and density among management regimes, we performed 260 transect surveys on 40 different study site pastures deployed among 7 different management regimes, varying in plant community composition as well as frequency (or occurrence) of burning, grazing, and mowing from 29 October 2008?7 April 2009 and 17 November 2009?17 March 2010. A total of 79 bird species (48 species in 2008?2009 and 66 species in 2009?2010) were recorded during this study. Sites that were recently (
