Both sexes are similar, while juveniles are more buff with some streaking on the belly.

SIZE: measures about 5.3 - 5.9 inches in length, with a wingspan of 7.9 inches.

WEIGHT: weighs about 15 - 30 grams.

CALL: Both males and females make a metallic call note.

SONG: A long series of "chip" notes that accelerate throughout.

NEST: The nest is a bulky cup-shaped with a domed top, made of grasses, leaves, bark, and other vegetative bits, lined with softer material such as hair or feathers. It is placed in a bush or cactus, relatively close to the ground.

EGGS: 2 - 5 white to pale pink eggs.

They forage on or close to the ground, moving through low vegetation or walking along the ground in search of food. They will often use their feet to scratch at the ground or in leaf litter, in a similar manner to many towhees.

The oldest recorded Olive Sparrow was at least 8 years, 3 months old.

The Olive Sparrow is the only sparrow with an olive back.
