Just to clarify my
understanding there are five “Animal Classes”
with 'vertebrates' (backbones):
Mammals...Birds...Fish...Reptiles...Amphibians.
Mammals
include people, dogs, cats, horses, duckbill platypuses,
kangaroos, dolphins and whales. What do all these have in common?
MILK! If an animal drinks 'milk' when it is born and has hair on its
body, it belongs to the mammal class.
Birds
are animals that have feathers and that are born out of
hard-shelled eggs.
Fish are
vertebrates that live in water and have gills, scales and fins on
their bodies. Some fish can climb onto land and hop about.
Reptiles
are a class of animal with scaly skin. They are cold-blooded and are
born on land. Snakes, lizards, crocodiles, alligators and turtles
belong to the reptile class.
Amphibians
are born in the water. When born, they breathe with gills like a
fish. But when they grow up, they develop lungs and can live on
land.
Any animals that have more
than 4 jointed legs are Anthropods.
Insects, spiders and
crustaceans all belong to this class of animals.
Do Wolves Really Howl
at the Moon?
As mystical and ancient
as the notion of 'wolves howling at the moon', they are predominantly
nocturnal animals and are therefore, naturally associated with
darkness and with the moon. This romantic idea came from ancestors'
ancestors. Since the Neolithic Age, wolves have been paired with the
moon, whether in images or literature. Native American Seneca tribes
believe that it was actually a wolf that sung the moon into
existence. With this historical significance, it really isn't
surprising that this ancient folklore has evolved into today's
popular belief.
Since wolves are
nocturnal, naturally they will be more vocal at night. They point
their faces to the sky to howl, simply because of the acoustics
generated from this gesture...the higher they send the sound, the
further it will travel. Wolves howl as a means for long-distance
communication...and can convey a range of information with different
pitches and suspension of notes. They may be rallying their
pack...giving a signal as to the alpha wolf's location...delivering a
warning to other packs to remain outside this wolf's territory...a
chorus of howling can act as protection for the pack!
When
my daughter was in High School and my son in University, we had a
black and white Siberian Husky called Kiska. On very cold winter
nights, living outdoors with a unique doghouse for shelter, she'd go
to the back fence around midnight...raise her face to the moon and
howl and howl. Fearing that neighbours would be disturbed by this
eerie 'wilderness call', I brought her into the house for a few hours
on those nights. My son and Kiska had a special camaraderie, so I
concluded she was communicating with him at University...to tell him
about the moon, the stars, the frigidity of the night and her
loneliness without him at home.
Why Do Lions Roar?
Lions are very protective
of their homes...and a male lion whose main job is to defend his
pride, uses his loud roar to warn off anything that might threaten
his family. On a still night, lions can be heard 7 to 8 km away.
Roars are not only used to 'proclaim territory' but also to rally
straying members of his tribe...and they do this every evening!
Roaring is also one of their strategies for catching prey and as they
creep up on them...and when they are close enough, they will let out
a roar that confuses that animal and strikes fear into the
lion's prey. The prey cannot then 'think' or 'react' correctly out of
fear and so is trapped and caught by the lion.
The Trumpeting of
Elephants
Living in herds, the
African elephants trumpet, growl and rumble in a classic example of
elephant conversations. Being highly intelligent, they are most
fascinating to watch. All parts of their body movement convey
messages; in verbal form they have very loud trumpeting sounds which
can signify aggression as well as danger...this
trumpeting can be sent at various frequencies depending on who they
wish to contact. It is common for them to generate sounds that can
be heard for several kilometres. When males want to attract females,
they can offer very high-pitched sounds for many hours throughout the
day...which may actually cause a female to emit powerful hormones
announcing a desire to mate with him
.
.
Bees Sting
A honey bee that is away
from the hive, foraging for nectar or pollen, will rarely sting ~
except when stepped on or roughly handled. Honey bees will actually
seek out and sting when they perceive the hive to be threatened,
often being alerted to this by the release of attack pheromones.
Bee stings could be of a bee, wasp, hornet or yellow jacket
(even the bite of a horse-fly).The stings of most of these species
can be quite painful. A human body's reaction to a bee sting may
differ significantly
.
.
Beware of Piranhas
They only exist in mostly
white-waters of South America...some in black-water, some in
clear-water...best habitat for them is where 2 rivers meet for
combination of two waters. Ranging in length from 8 to 20 inches,
they have long razor-sharp-teeth. By travelling in schools of 100's
and 1,000's, they present a daunting challenge to predators, as well
as with animals and humans. Jungles of the Amazon Basin are nature
to them. While feared by swimmers for its aggressive attacks, they
feed mainly on aquatic plants, insects, smaller fish and
snails...occasionally feasting on small mammals and birds that fall
into their environment. Piranhas are the prey of river dolphins,
large birds, crocodiles, turtles and larger fish
.
.
The Songs of Birds
Birds can sing at any
time of the day, but during 'Dawn Chorus' their songs are often
louder, livelier and more frequent. It's mostly made up of male
birds, attempting to attract mates and warn other males away from
their territory. Their 'chorus' comprises trills, tweets,
melodies and crescendos. Bird songs of the 'Dawn Chorus' (when
the early hours are coolest and driest), lack the atmospheric
variables ...which allow the bird songs to travel farthest,
giving their voices better range.
In my neighbourhood are
many trees, often around 5 am when I'd be wakened by the many birds
with their morning 'wake-up-calls'; frequently I'd hear a nearby
FREE-DOM...then from a more distant place, Free-dom sent
in reply as an echoing response (my translation) for their message
which was a series of 'song and response'. Later I discovered a red
cardinal in a tree near my parking space...and further away was his
brownish mate...my morning songsters!
A delightful picture in my
living room is of 5 small bluebird chicks
sitting side by side on a
branch...titled “The Chorus Line.”
An Environmentalist’s
Reflection (by Jane Goodall): The tree I had in the garden as
a child, my beech tree ~ I used to climb up there and spend hours. I
took my homework up there; I took, my books up there . If I was
sad... it just felt very good to be up there…among the green leaves
and the birds and the sky…just listening to the messages of nature
