What a surprise to have two male Rose-Breasted Grosbeak birds on our
bird feeder in the month of May. Then to our amazement we had three
females appear! These birds are neo-tropical migrants. They spend the
winter months in an area from central Mexico to northern South America.
In May, they return to the North American continent and take up
residence in the northeastern United States and southern Canada. Their
habitat is shrubbery, woodlands, and brushy stream areas adjacent to
open fields. The male birds arrive before the females, select a nesting
territory, and begin singing to attract a prospective mate.
As
well as, the sunflower seeds from our bird feeders, a typical diet for
these beautiful birds might include seeds of elms, blossoms of hickory
or beech trees, buds of white ash, flowers and fruit. Insects of the
forest such as gypsy moths and tent caterpillars are also table fare
for Grosbeaks. The Grosbeaks savor crop damaging beetles, locusts, cut
worms, chinch bugs and other creepy crawlers. Because of this they are
sometimes called the "potato bug bird".
The Rose Breasted
Grosbeak is of the finch species. The male has a black head, back,
bright red breast and white rump, sides and belly. The bird's wings are
black with white patches above and red, white and black below. The bird
in flight reveals startling pink-red linings on the wings. These birds
have a large, stout, pale pink-almost white, conical bill. They have a
long slightly notched black tail with white patches.
The female
Grosbeak has a buff color breast with heavy brown streaks on the sides,
making it seem almost drab compared to the male bird. The only "showy"
part of the female is her yellow wing linings, only visible in flight.
The male and female birds bear little resemblance to each other. Except
for the bill, they can be easily mistaken for two different species.
Both male and female birds are about the size of a starling.
The
male bird is a proud and devout family man. He helps build the nest of
twigs and grasses usually in a small tree or bush five to fifty feet
high. The nest appears as a flimsy constructed saucer. He also takes
his turn incubating the eggs. The female Grosbeak lays three to five
light green eggs with brown spots. Incubation time for the eggs is
thirteen to fourteen days. He sits on the nest from morning to
afternoon, while the female gets the night shift. After hatching,the
baby birds leave the nest in nine to twelve days. The male bird is so
happy to be included in the family chores that he even sings while on
the bird nest. Both the male and female birds sing; their songs very
similar to a robin. Rose Breasted Grosbeaks often sing from the
treetops in their loud, clear song. It is richer and a more melodious
version of the lengthly sing-song of the robin. The notes are sweeter
and they have more slurred whistles.
The Rose Breasted Grosbeak
is a favorite bird in Mexico, Central and South America. Here the
locals are fond of them and often capture them for pets.
We had
not seen a Rose Breasted Grosbeak before and were so happy to have them
come to our bird feeders. They have already moved on for their flight
to the northeastern states. We hope when the late summer days start to
become crisp, these beautiful birds will again visit our bird feeders
on their way south for the winter.
