Here's a presentation I did one time about (spoiler alert,
mouse over)
█████████████████ .
I've added captions to each slide with a rough estimate and
translation of what I said in that slide.
This presentation was not fact-checked nor peer-reviewed,
and I have not taken any time to update it or improve it
beyond removing my name from the first slide.
Here's the presentation:
This presentation is about a descendant of modern
dinosaurs... a creature domesticated by humans for
at least seven thousand years... capable of
adapting to live nearly anywhere... a creature we
see often but which most people hardly know... So
what could this be, you may ask?
Why, pigeons and doves of course!
This presentation will discuss the history of pigeons
and doves relationship with humans, as well as
discussing a few interesting wild species, and finally
pigeons and doves' place in current times.
Historians have found evidence of pigeon and dove
domestication dating back as far as 5000 BC, possibly
even earlier. It is thought that they were largely kept
for food in early times, and later found more symbolic
use.
They had an important presence in Egypt, where their
bones can be found in tombs, seemingly as part of
funeral meals. It is also thought that Rameses III made
a sacrifice of 57 000 pigeons to the god Ammon at
Thebes.
These are just a few of the documented religious uses
for pigeons in history. Pigeons and doves
(frequently white pigeons) are often viewed by religions
as a symbol of peace and good news. Temples in many
countries have huge populations of pigeons, which are
fed by visitors to the temple. For example, the prophet
Mohammed of Islam is often depicted with a dove on his
shoulder, and over the years it has become tradition for
religious pilgrims to feed the pigeons in Mecca.
Pigeons have had many roles in human society beyond
religion.
As I mentioned previously, they were often raised for
meat, either for their well-developed flight muscles, or
for squab, which is to say young pigeons.
Pigeons are also well-known for their
excrement. Or perhaps badly known. But their excrement
is actually surprisingly useful for making fertiliser.
They were often kept in large numbers for this purpose
as well.
Pigeons are also popular in sport, as much in the past
as they are today.
One such sport is triganieri, a sport with the goal of
capturing other keepers' pigeons. This involved
specially breeding and training pigeons to lure the
other's birds to your own loft. Sometimes the captured
birds were sold back to the original owner.
Falconry is another sport involving the use of birds of
prey to capture birds such as pigeons. These pigeons
would often be captured or bred in captivity prior to
release. This sport declined in popularity as firearms
became more popular.
I would be remiss to leave out pigeon racing, but I will
discuss it in detail later in the presentation.
Pigeons are known for their incredible homing ability.
In pigeon racing, for example, the birds may travel
between 300 and 900 kilometres from the release site to
return to their home. Pigeons have been used
as messengers for thousands of years, with traces found
in numerous societies such as ancient Rome. Pigeons were
often messengers in wartimes, such as during the siege
of Paris in the war of 1870, where the use of microfilm
allowed pigeons to carry more information in a smaller
form factor. This led to the occupying force outlawing
pigeon keeping, with grave consequences for those found
with the birds in their possession.
Messenger pigeons were quite popular for
intelligence in the first World War, with some even
being equipped with little cameras, so they would
photograph enemy territory while flying overhead. To
ensure a proper flight path, busses were converted into
mobile lofts so that many pigeons could be moved to the
other side of the location of interest all at once.
One of the most well-known pigeons of wartime is
Cher Ami, whose name means Dear Friend. On october 3rd,
1918, 500 men were stuck with no food nor ammunition
near Argonne in France, and they were being bombarded.
In the span of 24 hours, 300 lives were lost and the
commander Major Charles Whittlesey sent a message by
pigeon: "Many wounded, cannot evacuate." This pigeon,
unfortunately, never made it to its destination as the
enemy opened fire. A second pigeon was released,
and still no luck. The third, Cher Ami, took off,
was struck in mid-air, plummeted to the ground, but got
up and kept flying. 40 kilometres in 25 minutes, even
after having been shot through the chest, one eye gone,
and one leg barely holding on, she made it home and
saved 194 lives. Cher Ami lived on, now a hero, and
standing with a wooden prosthetic leg. Her remains are
now housed at the Smithsonian, pictured here.
Of course, Cher Ami was not the only brave bird
out there. Pigeons represent the majority of Dickin
Medals issued to date, showing that these little birds
have saved many, many lives.
So now that we're all on the same page about how
incredible pigeons can be, I should probably note that
rock doves, or pigeons as we know them, are certainly
not the only interesting members of their family. Around
here, we also commonly see—and hear the low coos
of—mourning doves, a fairly close relative. Their song
is often mistaken for the hoots of owls, but indeed the
source is a surprisingly cute little brown bird. Pigeons
and doves come in all shapes, sizes and colours, though.
Across the globe, we find incredible species such as the
nicobar pigeon with its incredible mane and irridescent
body, the Victoria crowned pigeon which has the most
incredible hairstyle, and even species like the bleeding
heart dove which truly wears its heart on its sleeve. It
may be worth noting as well that the nicobar pigeon is
thought by some to be the closest living relative of the
famous extinct dodo bird.
But it doesn't stop there! Even the pigeons
we know come in all shapes and sizes. Fancy pigeons are
a part of the same pigeon species we've domesticated
since time immemorial, but they have been bred for
various purposes, sometimes relating to food or racing
performance, or sometimes for tricks or shows.
Pigeon racing has become a huge international
sport, with dedicated breeds of fancy pigeon, tons of
infrastructure and support for the sport, as well as top
athletes being sold for top dollar in order to breed the
next generation of promising racers. For example,
Playboy, the winner of a 620 mile race in 2008, changed
hands for the impressive price tag of 144 thousand
dollars.
Pigeons are also bred for various characteristics
to compete in shows, similar to shows built around the
breeding of dogs or cats. Some breeds are selected for
their ressemblance in stature to other types of birds
such as birds of prey, some are bred for impressive
feather displays such as huge tail fans or a coif of
neck feathers, some have a thin body compared to their
inflatable throat pouch, and some are even curly! There
is a pigeon breed out there for everyone, I believe.
Pigeons and doves can also make excellent pets, with a
few species being commonly kept. Of course
typical gray or fancy pigeons make excellent pets,
thanks to their long history of domestication making
them perfectly suited for living with humans. They are
even smart enough to keep outside of cages in your home,
being about as good at staying out of trouble as other
pets like cats. Contrary to popular belief, they are
very hardy birds as well, and can live to around 15
years! Barbary doves, also called ringneck
doves, are a somewhat domesticated species which are
quite popular too. They are easier to keep in a smaller
space as they are smaller than pigeons, and they could
use the extra security and supervision since they are
not quite as good at being independent. Due to being
domesticated, they have very little sense of direction,
so care should be taken to not lose them out a window,
as they may not find their way back. They have a similar
lifespan to pigeons and they are easy enough to hand
tame. Finally, diamond doves are an even
smaller species of pet doves. They don't have a long
history of domestication, so they tend to be more
skittish around humans, meaning they do best in a
comfortably large enclosure much of the time. They are
uniquely cute, with their blueish coloration and bright
eye ring. All of these make excellent
companion animals. They tend to be easy to tame and
train, especially the more food-motivated individuals.
They are inexpensive and easy to keep, and they are
gentle both physically and aurally, their soft coos
being quite pleasant to many folks. My own ringneck dove
Curie is pictured here on the right!
Pigeons are also great contributors to science.
Alongside rats (which are also under-rated), they are
well-known for their use in behavioral research, such as
the experiments popularized by B. F. Skinner and his
Skinner boxes. Pigeons have made important contributions
to research on cognition, neurology and even cancer
research.
Pigeons' sense of direction is also something of a
mystery which scientists have been hoping to figure out
for some time. There are many theories as to how they
navigate, which may involve landmarks, smells or even
the detection of Earth's magnetic field. It would seem
that pigeons use many senses to find their way home, and
they rely on access to the sky during their development
to gain this navigational instinct.
Truly, pigeons and doves are amazing creatures. This
presentation has only scratched the surface of their
world. I hope that in the future you may see pigeons
with a new sense of curiosity.
