There are more than 338 recorded hummingbird species worldwide, and many birding enthusiasts would agree that they are top of the list as the most interesting little birds of the nearly 10,000 bird species found around the world. With their brilliant iridescent coloring, wings flapping in a blur and ability to dart in all directions, or hover in one spot, hummingbirds are extremely entertaining to watch.
Interestingly, the color of a hummingbird’s gorget (throat feathers) is not a result of feather pigmentation, but of light refraction caused by the structure of the feathers. They are unable to hop or walk, but can move sideways while perching. The smallest species is the bee hummingbird, endemic to the main island of Cuba and weighing only 1.6-2 grams with a length of 5-6 cm. Up to 30 percent of the hummingbird’s weight is in the muscles used in flight – the pectoral muscles. With wings that beat between 50 and 200 flaps per second and an average heart rate of more than 1,200 beats per minute, a hummingbird uses an amazing amount of energy and must consume up to half of its weight in sugar daily. They harvest nectar from flowers with fringed, forked tongues that lick 10-15 times per second.
The rufous hummingbird migrates a distance of more than 3,000 miles from its Alaskan and Canadian nesting grounds to its Mexican winter habitat – the longest migration of all the hummingbird species. Some hummingbird species such as the rufous, calliope, broad-tailed, Anna’s, black-chinned and Costa’s are known to inter-breed and create hybrid species, making the birder’s identification task more challenging.
Following the completion of a species status review in 2012, the US Fish and Wildlife Service is proposing that the Honduran Emerald hummingbird be listed as endangered. Endemic to five small valleys in the Central American country of Honduras, it’s estimated that the Honduran Emerald hummingbird population has decreased to fewer than 1,500. With loss of habitat being the primary cause of the decline in numbers, it is feared the decline will continue as land is cleared for establishing plantations and pastures for cattle. The good news for the brightly colored little bird is that the Honduran government is aware of the problem and has formed the Honduran Emerald Hummingbird Habitat Management Area which includes dry forest habitat suitable for the Honduran Emerald hummingbird and may very well turn the decline around.
