Registros nuevos y notables de aves en el AICA Humedales de Alvarado, Veracruz.

Based on field observations from March 2003 to January 2015 in the Alvarado Wetlands (aw), we present records of 10 bird species found outside of its distribution or despite having their potential distribution in the Alvarado Wetlands, there is a lack or there are a few records in that area. The Common Loon (Gavia immer) and the Masked Booby (Sula dactylatra) were recorded for the first time; the Surf Scoter (Melanitta perspicillata), the Bonaparte's Gull (Chroicocephalus philadelphia), the Ruby-crowned Kinglet (Regulus calendula), and the Prairie Warbler (Setophaga discolor) were recorded for the second time in the area. We also include the Red-legged Honeycreeper (Cyanerpes cyaneus) and the Scarlet Tanager (Piranga olivacea), which are rare in the area, and the Lesser Goldfinch (Spinus psaltria) and the Eurasian Collared-Dove (Streptopelia decaocto), species that have recently expanded their distribution. These records can be attributed to different causes: migratory behaviour, weather, human introduction, habitat modification, and an increased monitoring effort. [ABSTRACT FROM AUTHOR]
