Species Profile:
Ovenbird
The Ovenbird (Seiurus aurocapillus) derives
its common name from its distinctive
nest
which is domed and has a side entrance,
giving
it the appearance of an old-fashioned
oven.
Made of grasses and fibrous bark, the
nest
is built by the female on the ground.
She
places dry leaves and sticks on top
of the
dome and may line the inside with deer
hair.
Her four or five eggs are white with fine
speckling and a wreath of brown, gray
and
lilac spots around the larger end.
They hatch
in about 12 days, and instead of just
sweeping
the shells out the door the female
eats them!
The young leave the nest in a little
over
a week. Each parent takes half of the
fledglings
under his or her wing, so to speak,
and feeds
them for up to three weeks.
The Ovenbird, which is larger than most of
its fellow warblers (six inches from
tip
of beak to tip of tail), eats mostly
insects
and spiders found on the ground but
occasionally
takes seeds and berries as well.
Well-camouflaged by their olive-brown back
and streaked breast, Ovenbirds are
hard to
spot. Once you see them, though, there's
no mistaking the orange stripe on their
heads
which accounts for their species name
aurocapillus.
It is usually the Ovenbird's call that
reveals
its presence, though, the famous "TEACHER,
TEACHER, TEACHER, TEACHER" which
gets
louder with each syllable!
Robert Frost, in his 1929 poem aptly entitled
"The Ovenbird" wrote:
There is a singer everyone has heard, Loud,
a mid-summer and a mid-wood bird,
Who makes the solid tree trunks sound again.
He says that leaves are old and that for
flowers
Mid-summer is to spring as one to ten.
He says the early petal-fall is past
When pear and cherry bloom went down in showers
On sunny days a moment overcast;
And comes that other fall we name the fall.
He says the highway dust is over all.
The bird would cease and be as other birds
But that he knows in singing not to sing.
The question that he frames in all but words
Is what to make of a diminishing thing.
Unfortunately, Ovenbird numbers have shown
a significant decline in the last 20
years.
This is partly due to their preference
for
large, undisturbed tracts of deciduous
or
mixed forest as breeding habitat; so
many
of these areas have been logged or
developed.
Lit buildings are also a threat to
night-migrating
Ovenbirds. In 1997, over one-fifth
of the
birds found by FLAP were Ovenbirds.
Their
vulnerability makes them that much
more precious,
and our desire to protect them that
much
stronger.
