Rare Albino Hummingbird Seen In Colorado

A rare albino hummingbird may have been spotted in Colorado.
Albino hummingbirds have a genetic condition that prevents their body from producing a natural chemical called “melanin.” Melanin is a chemical that gives most birds their beautiful colours.
Because Albino hummingbirds aren’t coloured, their feathers are white. They have pink bills and whitish or pink legs and feet. They may either have red or pink eyes.
The pink or red colour is caused by the red of their blood vessels.
One writer who specializes in birdwatching (or “birding”) says albino hummingbirds are extremely rare. The writer said a white hummingbird has also been seen recently in Virginia, a coincidence that is rarer still!
Birders will be watching carefully to see if they can photograph the bird again, so they can be sure it truly is an albino hummingbird.
