Notes ⁵

Sparrow-sized birds that go around in small groups. The females look pretty similar to female House Sparrows, but the males have red all over their heads and fronts (some birds have yellow or orange instead of red, but red is much more common). Both sexes also have chests and bellies with lots of brown streaks, whereas House Sparrow's undersides are unstreaked grey.
