There exists over 134 species of hummingbirds
in all regions of mainland Ecuador. The most amazing ones occupy
the high altitude regions of the Andes right up to the
glaciers of 5000m. To survive that high up, those species of
colibries (Spanish for hummingbirds) go into a state of
torpor at night, diminishing its heart rate to conserve energy
in the cold of the night. |
