Autumn is only now truly settling in, but the birds have
been on the move for months. In the
previous post, I talked about some of the migrating species I’d seen, and now I’m
overdue to discuss even more of them! Frustratingly,
not all of these birds are easy to see.
Some of them—particularly the warblers—are notoriously uncooperative. The photos I manage to snap of these feathered
sprites have an unfortunate tendency to recall Where’s Waldo? illustrations.
Where’s the warbler?
In the case of this picture of an adult male American Redstart, you have to look far over to the right to see the bird, displaying his
gorgeous orange-on-black plumage.

This photo of an immature male redstart (with yellow-and-gray
feathers) is identifiable, but not much else.
These tiny birds repeatedly thwarted my attempts to capture them on
camera! Although redstarts are breeding
birds in a few locations in my area, they are much more common in the fall, when
they can be expected to be seen in almost any wooded habitat from about September
through mid-October.
Tennessee Warbler -- with food! |

Tennessee Warblers are also quite abundant fall migrants. Their foraging behavior of methodically
probing clusters of leaves for insects makes them a little easier to photograph
than restarts, which flit around in thickets, catching a lot of their food on
the wing. “Tennessee Warbler” is really
a misnomer, since this species nests nowhere near Tennessee; Alexander Wilson,
an early ornithologist, just happened to discover it in that state during
migration, so the name stuck. Tennessee Warblers are pretty drab, but they always show pale
“eyebrow” markings and white undertail coverts.

Yellow-rumped Warbler |
Yellow-rumped Warbler. The yellow patches on the birds' sides are noticeable even when the yellow rump patches are hidden from view. |
Of course, warblers are far from the only birds migrating
right now. Yellow-bellied Sapsuckers (the
name that sounds almost too silly to be true) have arrived for the winter,
joining the permanent-resident woodpeckers, such as the extremely common
Red-bellied and Downy Woodpeckers.
Sapsuckers have bold white wing stripes and a mewling call, which make
them fairly easy to identify.
This Yellow-bellied Sapsucker is a juvenile, which is why it has brownish markings on its head instead of bolder black, white, and red ones. |
For the sake of comparison, here’s a Red-bellied Woodpecker
(another name that can cause some confusion, since the red on the crown and
nape is far more prominent than the few reddish feathers on the belly):
And here’s a Downy Woodpecker, with its spotted wings and
white back:
Another overwintering migrant is the Red-breasted Nuthatch,
a tiny bird that moves south in larger numbers during years in which conifer
seed production is low. This is referred
to as irruptive behavior, and is exhibited by many other species, including
Purple Finch, Evening Grosbeak, and Pine Siskin. I was lucky with the bird below; it had
apparently just recently arrived, and seemed somewhat disoriented—darting under the roof
of the patio and landing on the rocks beside the goldfish pond. I haven’t seen it since, though, and I wonder if it continued farther south.
