A Costa’s Hummingbird has to be cautious. At 3.5” long and 0.1 oz. most
everything threatens him.
Nevertheless, he is not shy or retiring.
Proudly projecting brilliant blues and violets, he takes
comfort in his ability to escape enemies with lighting speed and aerial
acrobatics.
With a resting heartbeat of 900 beats per minute, this
mighty, but tiny bird deserves admiration for more than just his good looks.
Perched in plain sight at the end of a twig he knows few
predators will mess with him, as pursuing him would be futile and the reward
would be negligible. His biggest annoyance seems to be other hummingbirds.
Costa’s Hummingbirds live in desert and semi-desert areas of
Arizona and Mexico. Surviving on flower nectar or the sugar water provided by
people who enjoy having them around, they are listed as ‘Least Concern’ by the IUCN* as to their
survival. Habitat loss is their most threatening problem as more and more
people move into the desert.
People may be their salvation though, if people enjoy them enough
to provide nectar and replant the natural desert flowers they depend upon.
