The Hummingbird,
Their name comes from the fact that they flap their wings so fast almost 80
times per second that they make a humming noise. A hummingbird’s maximum forward flight speed is 30 miles per
hour. These birds can reach up to 60 miles per hour in a dive, and hummingbirds
have many adaptations for unique flight. a
hummingbird takes an average of 250 breaths per minute. Their breathing pace
will increase when they are in flight.
Hummingbirds
include the smallest birds in the world, but that’s not it, also known as one
of most numbers of group birds, it is
difficult to estimate population numbers since there are many different species
spanning a large geographic area. There are more than 325 unique
hummingbird species in the world. Only
eight species regularly breed in the United States, the other species of the hummingbirds
are primarily tropical species and do not regularly migrate.
They are found in
Central and South America as well as throughout the Caribbean.Like other birds,
hummingbirds communicate via visual displays. Hummingbirds are very territorial
and have been observed chasing each other and even larger birds such as hawks
away from their territories.
During evolution,
hummingbirds have adapted to the navigational needs of visual processing while
in rapid flight or hovering by development of an exceptionally dense array of
retinal neurons allowing for increased spatial resolution in the lateral and
frontal visual fields.
Morphological studies showed that neuronal
hypertrophy, relatively the largest in any bird, exists in a brain region
called the pretectal nucleus lentiformis mesencephali (or nucleus of the optic
tract in mammals) responsible for refining dynamic visual processing while
hovering and during rapid flight, The enlargement of this brain region
responsible for visual processing indicates enhanced ability for perception and
processing of fast-moving visual stimuli which hummingbirds encounter during
rapid forward flight, insect foraging, competitive interactions, and high-speed
courtship.
Hummingbirds
primarily eat flower nectar, tree sap, insects and pollen. The hummingbird’s
fast breathing rate, fast heartbeat and high body temperature require that they
eat often. They also require an enormous amount of food each day. Hummingbirds
have a long tongue which they use to lick their food at a rate of up to 13
licks per second.
