The Common Redpoll visits Washington in some winters in flocks ranging in size from a dozen to hundreds of birds. Because its arrival is unpredictable, it is known as one of the irruptive species of northern birds, which, depending on weather conditions and the availability of food sources, will migrate farther south in some winters
The genus name Passerella (pass-er-EL-ah) is from Latin, passer, meaning a sparrow. The species name iliaca (eye-lih-AY-cah) is Latin relating to the marked flanks. The common name is from the reddish or tawny “fox” color of feathers. The Fox Sparrow (FOSP) is about 7” long with a wingspan of 10.5” and a weight of 1.1 oz. (32g). It is one of our largest sparrows.
