Varied Thrush |
Oh, so much fog and clouds this winter, and yet, we are way
shy on rain. We try to take advantage of
each sunny day. Today promises sun –
once the fog burns off. We decide to go
to the coast hoping to photograph varied thrushes. They are common along the coast in the winter
time. Varied thrushes remind me a lot of
robins, but they are much fussier about their habitat and their song is so very
different. Instead of singing a long
musical soliloquy like their cousin, the varied thrush pipes just a few
ethereal flute-like notes . I hardly
ever get to hear one because I don’t live where they breed. At least they come down to the valleys to
winter.
Just over fifty years ago Dale and I arrived in Alaska. When we stepped off the ferry in Ketchikan
our first new and delightful discovery on our Alaska adventure was the song of
the varied thrush. We fell in love with
their sweet, simple song.
So off to the coast today to see some varied thrushes. They won’t be singing, but the lawns at Shore
Acres State Park will almost surely have thrushes poking around on the short
grass.
We swing into the park to quickly verify the thrushes are
there, but then we go to another spot about a mile away to eat lunch and watch
for whale spouts. All is well with the
whales (grey whales are migrating south to their breeding grounds right now).
Backswimmer |
While we are eating, we occasionally hear a tap on our
windshield. Backswimmers are on the wing
and are attracted to our shiny glass. Do
you know what a backswimmer is? It is a
little bug about one half inch long, who rows around, upside down,
underwater. His paddles are two
specially adapted hind legs.
Backswimmers remind my of a one-man racing boat. Our windshield must look like water to the
backswimmers. One after another lands
briefly, then takes off again. I can
just imagine they are a little embarrassed by their mistake.
Soon it is time to head back to the thrushes …… but first I
want a quick stop at a small puddle in the ditch next to the road. The puddle is only about 2 feet x 6 feet, but
nearly always has water thanks to a seep.
What will be in it today?
I quickly realize the puddle is a bonanza of activity. Two weeks ago it was dulls-ville, but today
it has a good population of whirlygigs (small, black beetles that zip around on the surface of pond water, often in clusters) and backswimmers. I’ve hardly arrived, when another backswimmer
comes flying in and zips into the water in a flash. The pond seems to swallow it. Another comes in and another.
… and then a little
guy flies in. Much smaller. This one seems to struggle a bit to get
beneath the surface – it’s a water boatman.
Water boatmen are the small cousins of backswimmers. They have the good sense to swim upright,
but, they too, spend most of their time underwater. They like to hide in the muck where they find
their food. Both backswimmers and water
boatmen come to the surface, grab an air bubble, and can stay underwater for
long periods.
A Predacious Diving Beetle -- Colymbetes sp. |
It is the middle of winter, yet this especially mild, sunny
day has triggered all kinds of activity.
I never expected today would be a good day for insect watching. Most people in the park are here to watch the whales. As far as I’m concerned, far off
whales can’t compete with little bugs right at my toes.
I stand still and realize the pond has another surprise for
me. There is a backswimmer upright, on top
of the surface of the pond. I’ve always
watched them upside down in the water. A
moment later there are two on the surface.
A car comes by, throwing a shadow on the pond, and poof! They are underwater again.
All is quiet and I watch while one after another backswimmer
floats, belly up, near the surface and suddenly does a roll onto the
surface -- a roll that would make any
kayaker proud. Any good kayaker knows
the importance of being able to upright themselves once they have been
flipped. Soon I’ve got over a dozen
backswimmers flipped over onto the surface of my little pond. One flies off.
Another car comes along.
Most dive underwater again, but two more take to the air. I’ve seen backswimmers flying before, but not
often. Whenever I do, there seems to be
a lot on the wing, such as today.
Interesting that the water boatmen and at least two kinds of aquatic
beetles are flying too. This must be a
good time of year to disperse to new locations.
…. And the thrushes?
I confess, the insects kept us so busy time got away from us. We headed back to Shore Acres Park to hunt
down our varied thrushes, but found the
park was already closing for the day. No
matter. We’ll just have to try for the
thrushes another day.
