Natural history museum collections (NHCs) represent a rich and largely untapped source of data on demography and population movements. NHC specimen records can be corrected to a crude measure of collecting effort and reflect relative population densities with a method known as abundance indices. We plot abundance index values from georeferenced NHC data in a 12-month series for the new world migratory passerine Passerina ciris across its molting and wintering range in Mexico and Central America. We illustrate a statistically significant change in abundance index values across regions and months that suggests a quasi-circular movement around its non-breeding range, and use enhanced vegetation index (EVI) analysis of remote sensing plots to demonstrate non-random association of specimen record density with areas of high primary productivity. We demonstrate how abundance indices from NHC specimen records can be applied to infer previously unknown migratory behavior, and be integrated with remote sensing data to allow for a deeper understanding of demography and behavioral ecology across space and time.

Para el bosque mesófilo de montaña en México se ha sugerido la presencia de 125 especies de aves que se encuentran en riesgo o son endémicas. Esas aves requieren ser conservadas. En un tiempo de defaunación mundial, y de reducción de estos bosques, es importante determinar qué especies de aves aún habitan en este ecosistema. Del bosque mesófilo localizado en la Sierra Madre Oriental de México no se han publicado datos recientes de campo que indiquen su presencia. En este análisis reportamos los registros de especies de aves en riesgo realizados en 2016 en cinco Áreas Importantes para la Conservación de las Aves con bosque mesófilo de montaña (Sierra Gorda, Tlanchinol, Huayacocotla, Cuetzalan y Río Metlac) ubicadas en cuatro estados de México (Querétaro, Hidalgo, Veracruz y Puebla). En total registramos 60 especies de aves (48%) de las 125, 29 son consideradas amenazadas a nivel nacional y 34 presentan algún tipo de endemismo. Seis de las especies están protegidas globalmente (Dendrortyx barbatus, Ara militaris, Contopus cooperi, Ridgwayia pinicola, Setophaga chrysoparia y Passerina ciris). Esta información puede servir como base para lograr su preservación y establecer monitoreos, estudios y acciones de conservación dirigidos a especies en las zonas de bosque mesófilo.
