Green-crowned Woodnymph (Thalurania fannyi) - HBW 5, p. 585

French: Dryade de Fanny German: Grünkronennymphe Spanish: Zafiro Coroniverde
Other common names: Emerald-bellied Woodnymph (hypochlora)

Taxonomy: Trochilus Fannyi DeLattre and Bourcier, 1846, Río Dagua, near Buenaventura, Colombia.
Forms a superspecies with T. ridgwayi, T. colombica and T. furcata; species limits unclear, and all four have been considered conspecific. Alternatively, green-crowned present species sometimes considered conspecific with blue-crowned T. ridgwayi and purple-crowned T. colombica; this lump supported by great similarity of these forms, apart from crown colour of male, and indeed male of present species shows some blue feathering at rear of glittering green crown which decreases with distance from adjacent purple-crowned forms; also female plumages of present s..

Taxonomy: Trochilus Fannyi DeLattre and Bourcier, 1846, Río Dagua, near Buenaventura, Colombia.
Forms a superspecies with T. ridgwayi, T. colombica and T. furcata; species limits unclear, and all four have been considered conspecific. Alternatively, green-crowned present species sometimes considered conspecific with blue-crowned T. ridgwayi and purple-crowned T. colombica; this lump supported by great similarity of these forms, apart from crown colour of male, and indeed male of present species shows some blue feathering at rear of glittering green crown which decreases with distance from adjacent purple-crowned forms; also female plumages of present species and T. colombica very similar. Distinctive race hypochlora may be a separate species, or possibly referable to T. colombica. Race subtropicalis may not be distinguishable from verticeps. Four subspecies tentatively recognized.

Subspecies and Distribution:

  • fannyi (DeLattre & Bourcier, 1846) - E Panama and extreme NW to SW Colombia.
