I never knew there were so many different types of pigeons. This I believe is the rock pigeon though I don't see the bands of the wings that is talked about on Wikipedia. I know they have a bad reputation just because there are so many of them everywhere (just like my students). They do have some beautiful coloring, and just like my students, I need to remember to look at the individual and not just the entire group. That's not often easy (it's hard to see the trees for the forest). Oh my! I'm full of this as this is what we have been working on in class. These feathered friends were hanging out at the waterfront this week where I took a walk with my former partner, but still friend - P. Here are some fun facts about pigeons.
Cool Pigeon
Facts
Origins: Pigeons and doves have been around for a
long time—long before humans. Rock Doves are thought to have originated
in southern Asia several million years ago. Compare this to modern
humans that first appeared about 120,000 years ago.
Size and weight: A pigeon is about 13 inches (32
cm) in length from bill to tail and weighs a little less than a pound
(0.35 kg). Males are slightly bigger than females.
A pigeon family:
- Hen: an adult female pigeon
- Cock: an adult male pigeon
- Hatchling: a newly hatched pigeon
just a few days old
- Squab: a young pigeon from 1–30 days old.
When ready to leave its nest, a squab can sometimes weigh more than its
parents.
- Peeper or Squeaker: a young bird that is learning
to eat
- Fledgling: a bird that is ready to fly or that has
just taken its first flight
- Juvenile: a bird out of its nest and flying but
less than eight months old
Nest and roosting sites: A pigeon nest usually is
constructed on covered building ledges that resemble cliffs, a Rock
Dove’s natural habitat. They also nest and roost on the support
structures under bridges in cities and along highways.
Nests: Pigeons build their nests with small twigs.
A cock brings the nesting material to his mate, one piece at a time,
and she builds the nest. Nests are usually well-hidden and hard to
find.
Eggs and incubation: Pigeons usually lay two white
eggs. The parents take turns keeping their eggs warm (incubating).
Males usually stay on the nest during the day; females, at night. Eggs
take about 18 days to hatch.
Food for young: Both male and female parent pigeons
produce a special substance called "pigeon milk," which they feed to
their hatchlings during their first week of life. Pigeon milk is made
in a special part of the bird’s digestive system called the "crop."
When hatchlings are about one week old, the parents start regurgitating
seeds with crop milk; eventually seeds replace the pigeon milk.
Colors: There may be as many as 28 pigeon color
types, called "morphs," but Project PigeonWatch groups them into just
seven morphs. Pigeons
also have colorful neck feathers. These iridescent green, yellow, and
purple feathers are called "hackle." Adult males and females look
alike, but a male’s hackle is more iridescent than a female’s.
White "color:" White feathers are actually feathers
that have no color pigments. So, when you see white on pigeons you are
actually seeing
no color.
Feathers: Pigeons have many types of feathers
including contour feathers, the stiff feathers that give the body its
shape, and down, the fluffy insulating feathers. Many pigeon feathers
are accompanied by one or two filoplume feathers, which look like
hairs. These filoplumes may have sensory functions, such as, detecting
touch and pressure changes.
Eye colors: Adults have orange or reddish orange
eyes; juveniles that are less than six to eight months old have medium
brown or grayish brown eyes.
Leg and feet colors: Pigeon legs and feet are red
to pink to grayish black. Their claws are usually grayish black but can
be white on some pigeons. Some birds have "stockings," which are
feathers on their legs and feet!
Cere: The cere is the fleshy covering on the upper
part of a pigeon's beak. It is grayish in young birds or
juveniles, and white in adults. Albino birds may have pinkish
ceres.
Eyesight: Pigeon eyesight is excellent. Like
humans, pigeons can see color, but they also can see ultraviolet
light—part of the light spectrum that humans can’t see. Pigeons are
sometimes used in human search-and-rescue missions because of their
exceptional vision.
Hearing: Pigeons can hear sounds at much lower
frequencies than humans can, such as wind blowing across buildings and
mountains, distant thunderstorms, and even far-away volcanoes.
Sensitive hearing may explain why pigeons sometimes fly away for no
apparent reason: maybe they heard something you can’t.
Sounds: Pigeons make two types of sounds: vocal
(using voice) and nonvocal. The primary call used by males to attract
mates and defend territories is
coo roo-c’too-coo. From their nests they might say
oh-oo-oor. When they are startled or scared they might make an
alarm call like:
oorhh! Pigeon babies make nonvocal sounds
such as bill snapping and hissing. After mating, males often make
clapping sounds with their wings.
Unique drinking behavior: Most birds take a sip of
water and throw back their heads to let the water trickle down their
throats. But pigeons (and all of their relatives in the family
Columbidae) suck up water, using their beaks like straws.
Magnetic sensitivity: Do pigeons have compasses in
their heads? Not really, but pigeons, especially those bred for their
homing instincts, seem to be able to detect the Earth’s magnetic
fields. Cornell University pigeon researcher Dr. Charles Walcott says
that magnetic sensitivity, along with an ability to tell direction by
the sun, seems to help pigeons find their ways home.
Locomotion: On the ground, pigeons don’t hop the
way many birds do. They walk or run with their heads bobbing back and
forth. Pigeons are strong fliers and can fly up to 40 or 50 miles per
hour. Some pigeons are raised for their exceptional abilities to fly
fast and find their ways home. These pigeons may fly as far as 600
miles in a day. Although feral pigeons are good fliers too, most
of these birds seem to stay close to their regular feeding sites.
Natural predators: One species of falcon, Merlin,
eats so many pigeons its scientific name is
Falco columbarius
(with the "
columba-" meaning pigeon) and it was formerly
called Pigeon Hawk. Merlins are medium-sized falcons and although they
are not very common in cities, you can bet they are preying on pigeons
living in open parks near marshes and ponds. In cities where
Peregrine Falcons have become established, they
catch and eat feral pigeons, often carrying them back to feed to their
nestlings. Red-tailed and Cooper’s hawks also prey on pigeons in cities
and in rural areas.
Fancy pigeons: People raise all kinds of fancy
pigeons. The breeds have names, such as rollers, tumblers, and
fantails, which reflect the way the birds fly or the way they look.
Sometimes, people take their fancy pigeons to compete in shows.
