The Costa’s Hummingbird is named for the French nobleman Louis Marie Pantaleon Costa, and this particular species of hummingbird is native to parts of the desert southwest in the United States and sections of northern Mexico.
The Costa’s Hummingbird’s normal heart rate is between 500 and 900 beats per minute. At night, when the bird goes into a state of torpor, which is similar to hibernation, the heart rate can go as low as 50 beats per minute.
It is quite often difficult for researchers to study this particular species of hummingbird. The reason for this is due to the close resemblance of the young and the female Costa’s hummingbird to two other types within their range—the Anna’s and the Black-chinned hummingbird.
