Although
Central and South America are home to hundreds of species of hummingbirds,
only one species, the Ruby-throated, nests in Quebec. This is the smallest
birds species in Quebec, weighing only 3 g. Their unusually small size
causes them to require relatively large amounts of high energy food. Nectar
from flowers provides an ideal food source: the problem is that the suitable
plants don't flower until July. Consequently, the Ruby-throated Hummingbird
consumes tree sap during early summer. This food source would not be available
were it not for a species of woodpecker, the Yellow-bellied Sapsucker,
whose endless hole-drilling releases the tree sap required by the Ruby-throated
Hummingbird. In fact, the geographic range of the Ruby-throated Hummingbird
in Quebec is probably dependent upon where the Yellow-bellied Sapsucker
is found. Although it's hard to imagine, the tiny Ruby-throated Hummingbird
makes an annual migration to its wintering grounds in Mexico and Central
America. What's even more impressive is that this bird must make a 700
km, non-stop flight across the Gulf of Mexico! To make it across, this
bird stores up its own weight in fat reserves
