Eurasian
Collared Dove
A New Dove on the Block
by John C. Tyson
The Eurasion
collared dove is coming your way. If you haven't seen one
of these wild doves yet, you probably will soon, for the bird
has quietly and quickly become a common sight in many parts
of Florida and the Southeast, and has been spotted as far
north as Minnesota.
The Eurasion collared dove first appeared on this continent
in the 1980s. The bird originated a hundred years ago, mainly
thriving in Asia and Europe. By the 1950s the doves had naturally
extended their range all the way to the British Isles. The
species was introduced into the Bahamas during the 1970s,
and after expanding in and around these islands, soon migrated
naturally to the Florida peninsula.
Today,
these doves are commonly seen in Florida and surrounding southeastern
states, although many may mistake them for a domesticated
ringneck turtle dove - a domesticated dove often sold in the
pet industry - which it closely resembles.
Appearance
The Eurasian collared dove, Streptopelia decaocto, is a member
of the pigeon family Columbidae. Their body is nearly 11 inches
in length -- slightly larger than the turtledove. A black
ring with white edges circles the nape of its neck, which
is a pale gray color. The primary flights are quite dark,
giving a black appearance, and the plumage is grayer than
that of the turtledove. The long, square-tail has white corners
and a black base. When viewed from the underside, the collared
dove appears grayer than a turtle dove, with black visible
on the tail. The turtle dove is white with much less black
on the tail.
One effective
and very reliable means of identifying the Eurasion collared
dove is by its song. The collared dove's coo is a coarse,
rapid, three-part coo, in contrast to the melodic and easily
recognized coo of the common mourning dove and the ring-necked
turtledove's hollow-sounding two-part coo. Doves are very
vocal and often can be heard harmonizing during early morning
and evening hours. Next time you're out, pay attention to
the sound of the doves; you should be able to easily identify
the coos of different species.
Environment
Most doves prefer feeding on the ground, and the Eurasian
collared dove in no exception. The best place to observe doves
are in urban and suburban areas such as city and county parks.
Look for them feeding on the ground in open areas around road
sides and parking lots. Doves are also commonly seen in fields
where grains such as corn, soybeans and wheat are grown. Near
the end of the day, look for the Eurasian collared dove in
tree tops and on utility lines. Their feeding preference makes
them regular visitors to backyard feeding stations that provide
peanuts, thistle seed, corn and millet. They often consume
the seed that falls to the ground but will readily use a platform-type
feeder as well.
Like most
other doves, the collared dove builds a flimsy nest and rears
two young from each clutch. The Eurasian collared dove has
been observed nesting in southern states during nearly every
month of the year. These long nesting seasons in the South,
coupled with the warmer winters of recent years in the rest
of the country, have created rapid population growth and expansion.
In addition, the continuing urbanization in our country provides
new and well- received habitats for dove populations.
The Eurasian
collared dove is not the only dove on the move in North America.
The populations and ranges of white-winged doves, rudy-ground
doves and the Inca doves also have expanded notably in recent
population counts, as measured by the National Audubon Society
and the Cornell Laboratory of Ornithology, that conduct numerous
bird counts each year with the help of dedicated birders throughout
the country. Programs such as Project Feeder Watch, the Great
Backyard Bird Count and the annual Christmas Bird Watch also
gather statistical data which is used in mapping the species
growth and population dynamics of doves and other birds. Even
the common mourning dove is more common in many northern parts
of the United States than it was years ago, according to these
surveys. If you enjoy this family of birds, keep eyes open
and ears to the wind. You might be surprised at what is cooing
around the corner.
