Racing
homers, descended from the common pigeon, Columba livia,
are bred by enthusiasts throughout the country. New York City has
long been home to pigeon fanciers. Even today, flocks seen flying
at dawn or dusk may well be domesticated. The birds are trained
to fly free and return to the coop on command. Before they are one
year old, they may be raced against other birds. Homing pigeons
have been domesticated for more than 3000 years; prior to the introduction
of the telegraph, the carrier pigeon was an important means of communication.
Pigeons hatch after 17 days in the egg, and become full-fledged
in 28 days. An active enthusiast can cross adults from several generations
in the course of a single year. As a result, each breeder, over
time, creates his own unique strain. "I made them the way I wanted,"
Bonisisio says of his pigeons. "The bloodlines are from long-distance
birds. I have a breed of my own."
Maintaining
the flock is not expensive: about the cost of feed, or $30 a month.
However, there are fixed costs associated with getting started,
such as the pigeon loft itself. Transporting the birds to races
is expensive. In addition, cleaning the loft and maintaining the
birds properly is no small task. Breeding pairs themselves can often
be obtained for free from keepers who enjoy introducing newcomers
to the sport. Bonisisio was given his first pair of racing homers
by his uncle when he was 17. "The best pigeon I ever got I got for
nothing," he says. "She was a silver hen. Honey, I called her."
In
fact, many enthusiasts develop their bloodlines from birds given
to them by friends or relatives. Pigeon sites on the Web list genetic
variants and discuss common problems with breeding, such as the
emergence of undesirable recessive traits. But the big question
remains unanswered. What sense allows the birds to return home,
sometimes hundreds of miles distant, over territory they have never
encountered? Bonisisio, who looks much younger than his age, says
the sport helps keep him going. He admires pigeons for their constancy.
"You don't lose 'em," he says. "They always come home. It's just
a matter of who comes home the fastest. That's the wonder of the
birds-what makes them come back."

Exotic
Imports Affect Natives
The
importation of exotic animals, whether as pets or by accident, places
pressure on native species and can adversely affect whole ecosystems.
"Exotics are something that give us all a big headache," said Marcelo
Del Puerto, senior regional biologist at the New York State Department
of Conservation.
"Worldwide,
there is an onslaught of species moving around." In New York City,
said Del Puerto, there are a number of ecologically sensitive areas:
barrier islands in Queens, for example, or wetlands on Staten Island.
Non-native species, animals or plants, can do a great deal of damage
to protected natural areas as well as to crops and other industries.
Florida, said Del Puerto, has been "decimated" by the importation
of exotic pests.
"The
one thing that protects us from a lot of the pet species is our
climate," he noted. "If not for our winters there would be a lot
more things running around out there."
