About the Brewer's Sparrow

Brewer's sparrow (Spizella breweri) is a small, slim species of American sparrow in the family Passerellidae. This bird was named after the ornithologist Thomas Mayo Brewer. Adults have grey-brown backs and speckled brown crowns, both with dark streaks, and a pale eye-ring. Their wings are brown with light wing bars and the underparts are pale grey. Their bill is pale with a dark tip and they have a long notched tail. They are similar in appearance to the clay-colored sparrow (S. pallida) but do not have a pale stripe on the crown or grey neck patch.

Measurements: Length: 5.1–5.9 in (13–15 cm) Weight: 0.4–0.5 oz (11–14 g) Wingspan: 7.1–7.9 in (18–20 cm) The male sings to defend a nesting territory. The song is a long varied mix of notes and trills. Males have two distinct types of songs – classified as short and long songs.
