ADULT FEMALE Has metallic greenish yellow upperparts. Underparts grayish white with yellowish green feathering on flanks and a few dark spots (iridescent in the right light) on throat. Tail has striking white tips on outer three feathers and a dark subterminal band. IMMATURE Similar to adult female; immature males gradually acquire adult's head coloration.
