Identification

7.5cm

  • Bronze-green upperparts
  • White underparts
  • Rufous-edged black outer tail feathers

The female is similar, but her throat is white with dusky spots.
Young birds resemble the female but have buff fringes to the upperpart plumage.

Similar Species

Scintillant Hummingbird - the male is distiguishable by the orange gorget, but the female is almost identical. Look for a shorter section of rufous and brighter white tips on the Volcano's rectrices. The Volcano occurs at higher elevations, but in an area of range overlap, distinguishing the females can be very difficult in the field.

Taxonomy

Subspecies

Three subspecies are recognized for this species[1]:

  • S. f. flammula: (Purple-throated)
  • S. f. torridus: (Heliotrope-throated)
  • Sierra de Talamanca (Costa Rica) and Volcán Barú (western Panama)
  • S. f. simoni: (Rose-throated) - the male has a red gorget
  • Costa Rica (Volcán Poás, Volcán Barba and Cerros de Escazú)

The subspecies simoni,has in the past, been considered a full species: Cerise-throated Hummingbird.

Habitat

Found 1800 meters or higher in elevation in Paramo habitat, brushland, in gardens and clearings.

Behaviour

Breeding

The female builds a cup shaped nest from plant down high in a scrub or on a root below a south or east facing bank. The 2 white eggs are incubated by the female for 15-19 days; the young fledge after another 20-26 days.

Diet

The diet includes nectar, taken from a variety of small flowers, including Salvia and Fuchsia, and species normally pollinated by insects. It also takes some small insects.
