The American Tree Sparrow (Spizella arborea), formerly known as the Winter Sparrow, is a medium-sized sparrow.
Adults have a rusty cap and grey underparts with a small dark spot on the breast. They have a rusty back with lighter stripes, brown wings with white bars and a slim tail. Their face is grey with a rusty line through the eye. Their flanks are splashed with light brown. They are similar in appearance to the Chipping Sparrow.
This bird's song is a sweet high warble descending in pitch and becoming buzzy near the finish.
