Glittering-throated Emerald (Polyerata fimbriata) Science Article 1
L ESSON’S Emerald is a medium-sized hummingbird with a rounded tail Above it is bronze-green, darker on the head and tail, brighter and more glittering on the under surface. The bill is almost straight. Three males that I collected in Surinam weighed 4.5, 4.8, and 5.8 grams; two females weighed 4.9 and 5.8 grams. The sexes are indistinguishable in the field. The species occurs from northern Venezuela to southeastern Brazil. Peters (1945:64-65) recognizes eight races. The subspecies here reported on, A. f. fimbriata, occurs in eastern Venezuela and the three Guianas (Zimmer, 1950). In coastal Surinam, Lesson’s Emerald is the commonest hummingbird, even in the gardens in the town of Paramaribo.
