En general su territorio de invierno no está bien definido y se reconoce su presencia irruptiva durante la temporada migratoria en sitios más al este como la costa tejana del Golfo de México y algunos sitios del este de los Estados Unidos y del norte de México. En la Zona Metropolitana de La Laguna (estados de Durango y Coahuila) es el colibrí urbano más común aun cuando su reproducción en el altiplano mexicano no se ha registrado hasta ahora. En este sitio se le encuentra durante todo el año. Describo los registros realizados en esta zona con un reporte de anidación. Estos registros sugieren una distribución más amplia de la comúnmente aceptada para el colibrí de cabeza roja en México.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The distribution of Anna&#8217;s hummingbird (Calypte anna) comprises the western coast of the U.S.A., the southern coast of British Columbia in Canada and the northwestern Pacific coast of the Mexican state of Baja California entering Arizona and north western Sonora. In general, its wintering grounds are undefined and winter irruptions have been reported in places like the Texas Gulf coast and some other locations in the eastern United States and in Northern Mexico. In the metropolitan area of La Laguna (Durango and Coahuila states) it is a common urban hummingbird throughout the year even though its reproduction has not been recorded. Records of its presence and nesting in La Laguna are listed pointing towards a wider distribution of Anna&#8217;s hummingbird in Mexico.]]></p></abstract>
