Here is an excellent website on the ruby-throated hummingbird.
http://www.rubythroat.org/RTHUMain.html
Hummingbirds use a form of daily hibernation called "torpor" which is a
rest period where body temperature drops and metabolism is slowed down.
This usually occurs at night, but can also occur during the day. Torpor
is energy-saving, but hummers in a torpid state are more susceptible to
predation. Also, because their metabolism is slowed down, they cannot
make fat as they can when they are fully active. I just read a paper in
which the authors studied feeding territory and fat formation in the
blue-throated hummingbird. They found that dominant hummers that guard
nectar sources tend to use torpor to a lesser degree and form more body
fat. This is particularly important in migration when food sources may be
difficult to find.
A note about color. The metallic reds and greens seen in hummers are not
caused by red or green pigments. The color is "structural". That is, the
microscopic spaces between the structural components of the feather allow
only a certain wavelength of light to be transmitted (reflected) back to
the viewer. When viewed at an oblique angle, the microscopic spacings
change size relative to the viewer and that is why the red throat, for
example, appears black. This type of coloration is quite common in
nature, especially among insects like butterflies and tiger beetles.
Hope I haven't been too long-winded!
Cheers,
Pat

hoping someone could educate my wife and me on regarding a several
issues?
1) Last night, my wife and I
were eating dinner and watching the male HB. Anyway, we just noticed
a bright red patch under its throat. I have taken quite a
few close-up images and have not seen this before. Is the probably
another male, or is it a change in the one that has been hanging around the
most?
2) The last week or so it seems that
the male has shifted to coming to the feeder frequently, but not necessarily to
drink. It flys around, and darts back and forth. It seems like it
is patroling? Is this territorial behavior? We do have a female that shows
up occaisionally and he does tend to chase her off. But, she does come
back when he is not around. Also, there is another male that does come around
but is quickly chased by our resident one. However, the one getting chased off
seems rather persistent and keeps coming back.
