The Rock Dove was introduced to North America in the early 17th-century
by colonists who brought domestic pigeons to Atlantic coast settlements.
The Rock Pigeon has such a long history of association with humans, (having
been used for food and entertainment for over 5,000 years), that the original
range of the species is impossible to determine. Escaped (feral) pigeons
from pigeon breeders readily form flocks, and wild birds may join them.
The Rock Pigeon makes a flimsy nest, but it often reuses the location
repeatedly, building a new nest on top of the first. Because the pigeons
do not try to remove the feces of their nestlings, the nest turns into
a sturdy, potlike mound that gets larger month by month. Unhatched eggs
and mummies of dead nestlings may also get cemented into the nest.
Pigeons snap beaks, hiss non-vocally, clap wings, and stomp feet to communicate.
Bill-snapping accompanied by a hiss is from squabs responding to nest
intruders. Wing-clapping is on upstroke of postcopulatory and other display
flights. Foot-stomping, seemingly deliberate, is by birds alighting, one
foot first, exhibiting "footedness".
Some pigeons have "stockings", which are feathers on their
legs and feet.
Rock Pigeons are non-migratory, but nevertheless important in study of
homing and navigation. It is their well-developed ability to return home
from distant sites that has made them useful in the study of navigation.
Domesticated as racing pigeons, they have been bred for an ability to
return home speedily.
Pigeon homing is usually thought of as a two step process. Upon release,
a pigeon determines the home direction. This step is called position finding
or the "map". Once the home direction is determined, the pigeons
use a "compass" to fly in that direction. They can use the sun
as a compass, but when it is obscured they use the earth's magnetic field.
Birds that rely on feeding by humans adjust to human schedules. In cities,
may look for food at mid-day, when more people are out and about;
may identify and seek individuals known to supply food.
Both male and female Rock Pigeons produce "pigeon milk" which they feed to their hatchlings
Rock pigeons are monogamous;
mates pair for life.
