The [[throat]] is [[blue]] and the outer tail-feathers are [[Violet (color)|violet]], becoming blue towards the tips. The [[female]] is 9.5-11 centimeters long. The tail is shorter than that of the male but still fairly long and slightly forked. Females have a blue crown and [[white]] throat, [[breast]] and [[belly]]. The Long-tailed Sylph is almost the same in color but does not overlap in range. Males of the subspecies ''caudatus'' have a mostly blue tail and no blue throat patch, while males of the subspecies ''margarethae'' have green tips to the tail-feathers. Females have a [[rufous]] breast and belly. ==References== *{{aut|BirdLife International}} (2007) [http://www.birdlife.org/datazone/species/index.html?action=SpcHTMDetails.asp&sid=32190&m=0 ''Species factsheet: Aglaiocercus berlepschi.''] {{Webarchive|url=https://web.archive.org/web/20090102230703/http://www.birdlife.org/datazone/species/index.html?action=SpcHTMDetails.asp&sid=32190&m=0 |date=2009-01-02 }} Downloaded from http://www.birdlife.org on 16/9/2007. *{{aut|de Schauensee, Rodolphe Meyer & Phelps, William H.}} (1978) ''A Guide to the Birds of Venezuela'', Princeton University Pres
