- NATURE QUEST
-
- by Karen Garrett
-
- and Jon Barnes
-
- *****************************
-
-
- Put away the pith helmets! You
-
- don't need to journey to the deepest
-
- wilderness to study the wonders of
-
- nature. Chances are good that if you
-
- step outside your back door you will
-
- encounter a part of nature worthy of
-
- interest and celebration.
-
-
- Karen Garrett found one of the
-
- world's most remarkable creatures in
-
- her back yard and made it the subject
-
- of a beautiful computer graphic. The
-
- wonderous beast? The ruby-throated
-
- hummingbird!
-
-
- Of the 17 different species of
-
- hummingbirds that populate the
-
- continental United States, the ruby-
-
- throat is the most common and one of
-
- the most stunning. It can be
-
- recognized at a glance by the dark
-
- green plummage which surrounds its
-
- white feathered breast. The male of
-
- the species is distinguished by an
-
- irridescent red patch of feathers on
-
- its throat (hence the name
-
- "ruby-throated").

-
- FAST FACTS ABOUT HUMMINGBIRDS
- -----------------------------
-
-
- Average size: 3 1/2 inches in
- ------------ length.
-
-
- Average weight: 1/8 ounce (about the
- -------------- weight of a penny).
-
-
- Mobility: Flies in any
- -------- direction and can
- hover. Can fly 30
- MPH straight ahead.
-
-
- Wingbeats: 70 flaps per second.
- ---------- (note that a T.V.
- scan beam refreshes
- the screen only 60
- times per second!)
-
-
- Heartbeat rate: 600-1000 beats per
- -------------- minute (note that the
- human heart beats an
- average 60-80 beats
- per minute).
-
-
- Primary food: Plant nectar: up to
- ------------ twice its body weight
- per day!
-
-
- Reproduction Hummingbirds lay two
- ------------ pea-sized eggs. The
- female builds her
- nest and cares for
- the offspring alone,
- feeding them five
- times an hour by
- regurgitation.
-
-
-
- OTHER INTERESTING FACTS
- -----------------------
-
- - The hummingbird uses a specialized
-
- 'forked' tongue which draws the nectar
-
- by capillary action.
-
-
- - The tongue is also sticky, thus
-
- allowing it to catch small insects
-
- which supplement its diet.
-
-
- - The hummingbird's high metabolism
-
- causes it to have an average body
-
- temperature of 104 degrees Farenheit
-
- during the day. But at night, the
-
- bird's temperature plunges downward to
-
- that of air temperature, resulting in
-
- a form of 'hibernation' while it
-
- sleeps.
-
-
- - The ruby-throat makes an annual
-
- migration to Mexico and Central
-
- America during the winter, flying
-
- more than 600 miles non-stop across
-
- the Gulf of Mexico.

-
- HOW YOU CAN OBSERVE THE RUBY-THROAT
- -----------------------------------
-
- The graphic illustrating the map of
-
- the U.S. will show you the range of
-
- the bird. Generally, if you live
-
- anywhere east of the Rocky Mountains,
-
- you ought to be able to see the
-
- ruby-throat during the summer months.
-
-
- SET UP A HUMMINGBIRD FEEDER
- ---------------------------
-
- If you live in areas frequented by
-
- the ruby-throat, you can lure them
-
- into your back yard or porch by
-
- setting up a feeder. Hummingbird
-
- feeders are usually available at
-
- hardware or home supply stores. You
-
- may wish to buy the commercial
-
- 'nectar', or use a homemade recipe of
-
- 1 part sugar or honey to 3 parts
-
- water.
-
-
- (Each mixture has its weakness,
-
- though. The sugar mixture lacks the
-
- proteins and vitamins the birds need;
-
- the honey mixture has the proper
-
- nutrients, but during hot weather, it
-
- can putrefy quickly).
