ID tip
With a total length of 5–6 in (13–15 cm) and weighing 0.28–0.44 oz (7.9–12.5 g), it is a relatively large hummingbird. Males and females are virtually identical, differing only in size (especially wing measurements), with the females being some 20% smaller. Its upperparts are iridescent dull greenish, while the underparts are whitish, densely streaked with dusky. The neck-side has a relatively faint blue patch. The tips of the rectrices (tail feathers) are white, and there is a naked stripe on top of the head (but this is usually concealed).
