Registramos la presencia de leucismo en un individuo adulto de gallareta americana (Fulica americana) en el lago Nabor Carrillo en Texcoco, Estado de México. La gallareta americana es un ave de amplia distribución geográfica, común en hábitats acuáticos desde Alaska hasta el norte de Sudamérica. Observamos al individuo el 29 y 31 de mayo y el 26 de junio de 2020 en el cuerpo de agua. Aunque existen diversos reportes de aves con leucismo, este registro representa el primer caso documentado de leucismo para esta especie en México.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Leucism is a chromatic aberration, defined as the absence of melanin that is expressed in whole or in part of the plumage of a bird. We recorded an individual adult of American Coot (Fulica americana) with leucism in Lake Nabor Carrillo in Texcoco, State of Mexico. The American Coot is a bird with a wide geographic distribution, common in aquatic habitats from Alaska to northern South America. We observed this Coot on 29 and 31 May and 26 June 2020, in Lake Nabor Carrillo. Although there are several reports of birds with leucism, this record represents the first documented case of leucism for this species in Mexico.]]></p></abstract>
