Abstract

In October 2017, we opportunistically observed up to 50 Peregrine Falcons (Falco peregrinus) on a ship moored in the western Gulf of Mexico. All birds we aged were juveniles, and they hunted from the ship, frequently perching extremely close to one another (<1 m apart) on cables. Both the number of birds and also the very short inter-individual distances when perching make these observations unusual among the published reports for this species.

Resumen

En octubre de 2017, observamos de modo oportunista hasta 50 individuos de Falco peregrinus en un barco amarrado en el oeste del Golfo de México. Todas las aves eran juveniles y cazaban desde el barco, posándose con frecuencia extremadamente cerca uno del otro (<1 m de separación) sobre cables. Tanto el número de aves como las distancias muy cortas entre individuos al momento de posarse llaman la atención por lo inusual de estas observaciones según los informes publicados para esta especie.
