Ruby-crowned Kinglet

Ruby-crowned Kinglets are tiny songbirds with relatively large heads, almost no neck, and thin bills. They have small, thin, straight bills.

Both sexes :

length : 3.5 - 4.3 in (9 -11 cm)

weight : 0.2 - 0.3 oz (5 -10g)

wingspan : 6.3 - 7.1 in (16 -18 cm)

Ruby-crowned Kinglets are olive-green birds with a prominent white eyeing and white wing bar. The wingbar contrasts with an adjacent blackish bar in the wing. The 'ruby-crowned' of the male is only occasionally visible.
