Cynanthus lawrencei

Identification

Male

  • Metallic green upperparts and breast
  • Dark grey undertail coverts
  • Turquoise-green iridescent throat
  • Dark bluish, slightly forked tail with grey tips
  • Black-tipped slender red bill

Female: less colourful, pale post-ocular stripe, grey on auriculars and underside

Similar species

Broad-billed Hummingbird could occur as a vagrant on the islands where this bird exists. In general this differs in having a sparkling dark blue throat (cf sparkling green), although images show Tres Marias Hummingbird can have some blue feathers admixed. Images also show that the extent of the dusky undertail coverts is not consistently different between the two species.

Distribution

Tres Marías Islands (off western Mexico)

Taxonomy

This is a monotypic species[1].

This species was formerly included in Broad-billed Hummingbird.

Habitat

Seasonally try forest with some thorny-elements mixed in.

Behaviour

Seemingly no information is available. It is assumed to behave similarly to Broad-billed Hummingbird.

It may breed during the locally dry season.
