A distinctive, fairly large hummingbird with a super long bill. Note the streaky throat and breast, and dull green upperparts with a coppery crown. The tail has a pale gray base, a broad black band, and white tips. Sexes similar, although female lacks toothlike serrations on bill (nearly impossible to see in the field). Found in lowlands and foothills from extreme eastern Panama to northwest Ecuador. Typically occurs within mature humid forest where it feeds in the lower to middle levels.
