Subject: Hummingbirds ...

"kinda cool" morning ...
'cause after two weeks of waiting ...
saw my first hummingbird dining from the feeder in my back yard! :)

according to wikipedia ...
hummingbirds ...
- are among the smallest of birds, with most species measuring in the 7.5–13 cm (3–5 in) range
- can hover in mid-air by rapidly flapping their wings 12–90 times per second (depending on the species) ...
- they can also fly backwards, and are the only group of birds able to do so
- the "giant" hummingbird's wings beat at 8–10 beats per second, the wings of medium-sized hummingbirds beat about 20–25 beats per second and the smallest can reach 100 beats per second during courtship displays
- their heart rate can reach as high as 1,260 beats per minute
