dramatically" according to John Tautin,
writing in the Second Atlas of Breeding
Birds in Pennsylvania, with losses most
notable in northeastern and southwestern
Pennsylvania, and central Pennsylvania's
Mifflin and Juniata counties. However, as
I discovered, martins are more common
in Pennsylvania where there are Amish
farms, many of which contain martin
houses.
Since 1900, eastern purple martins
in the eastern U.S. have nested almost
entirely in human-made houses, but
previously they nested in abandoned
woodpecker holes in dead snags.
Purple martins are the largest swallows
in North America. Males are entirely
purple, but appear black in the field, while
females are pale below and have a pale
collar and forehead.
Purple martins arrive in northwestern
Pennsylvania from their winter homes
in Amazonian Brazil, near Manaus, in
late April, studies by Canadian biologist
Bridget Stutchbury and her students have
found. Putting geolocators on five purple
50
50
martins, those researchers found it took 23
days for the birds to reach northwestern
Pennsylvania. That's an average of 180
miles a day, including a nonstop crossing of the Gulf of Mexico. However, one
martin made it in 13 days, which meant it
flew 300 miles a day, on average.
Male purple martins arrive first and try
to claim as many compartments in a birdhouse as possible, and sometimes multiple
gourds, too. If each porch in a birdhouse
is divided by a barrier that prevents birds
from seeing into the adjacent apartments,
a single male defends less territory. This
enables more martins to occupy a house.
To attract a female, a male sails in a
wide arc, then returns with a steep dive
to his nest site. As he lands, he enters his
nest, turns around, pokes his head out
and sings. A female, more interested in
evaluating the nest cavity than the male,
visits repeatedly over several hours. The
male eventually starts accompanying her
when she leaves the nest site. After several
days, they move in together and greet each
other each time they are separated.
Purple martins have a wide variety of
calls and songs, but during courtship, the
male uses a series of clicks
called the "croak song" and
the female uses a "chortle
song." Most famous is the very
loud "dawn song," which
is used before daylight,
perhaps to attract other
martins to the bird house.
Studies of nest preferences for purple
martins indicate that
they like the higher
compartments in
bird houses and, the
deeper they are, the
more fledglings they
can produce. Best of
