In addition, one isolated population inhabits the Chongón Colonche cordillera in the coastal evergreen montane forest (600 m) located ca.

While the speckled hummingbird is the only species in its genus, evidence suggests that populations on either side of the Andes mountains are genetically distinct, especially due to its broad geographic and ecological distribution.

[3][6] Males do not participate in any part of nest building or brooding of the young, and disengage with female partners after copulation.

Speckled hummingbirds often travel several kilometers to avoid competition, making visits to the nest less frequent.

[7] After brooding and until the young have fledged, the adult will no longer enter the nest and instead perch nearby, potentially watching for predators.

Nests can be found all year round, and consist of a bulky cup shaped of moss and cobweb, lined with plant fibre.

The construction of nests have been observed on moss-covered trunks or on rocky ridges, at the entrance of caves, at a height of 1–3 m.[6] The species does not gather with others to feed, even on flowering trees.
