Beautiful Hummingbirds<br />Pictures by Tony Markle<br />Slideshow by<br />Mo’s Creations<br />January 17 2011<br />
Hummingbird is a small bird of the Trochilidae family. <br />The rapid beating of the hummingbirds wings <br />(60 to 80 beats per second) makes the distinctive <br />humming sound from which they get their name.<br />
The hummingbird is the smallest bird and also the smallest of all animals that have a backbone.<br />
Because a hummingbird can rotate its wings in a circle, they are the only bird that can fly forwards, backwards, up, down,<br />sideways and hover in mid air. <br />
Hummingbirds are the second largest <br />Family of birds with 343 species. <br />
A hummingbird has a heart rate that can reach up to <br />1,260 beats per minute.<br />
Percentage wise, the hummingbird has the largest brain of all <br />birds (4.2% of its total body weight).<br />
Hummingbirds have very weak feet and use them mainly <br />just for perching. <br />
During courtship dives a hummingbird does, can reach speeds up to 60 miles per hour and can average speeds of 20 to 30 miles per hour. <br />
To conserve energy while they sleep or when food is <br />scarce, they can go into a hibernation-like state (torpor) <br />where their metabolic rate is slowed to 1/15th of its normal rate. <br />
The foundation to make the perfect nest is made of spider webs due <br />to their sticky nature. Next a layer of soft materials are added such <br />as moss or leaf hairs.<br />
Hummingbirds are found only in North America and South America.<br />The hummingbird range extends as far north as South Eastern Alaska<br />and the hummingbird range extends as far south as southern Chile.<br />
South America has the biggest variety of hummingbirds and more than half <br />The species are found there. The country of Ecuador in North Western South America has the largest number of hummingbirds of any one country with 163 different species. <br />I hope you have enjoyed this slideshow.
