"The chickadee is a symbol of faithfulness. It
lives the year around in
the same region. It never deceives its human
friends, as so many
birds do, by changing its coat and colors. In
the summer, to be sure, it
is not much seen. .... But with wintry blasts,
time the others go south,
the Chickadee begins to be noticed. Then there
comes a time when it
is almost the only thing to lend a touch of life
and a note of gladness
to a bleak outdoors.

Now that fall has arrived and the excitement
of spotting the many migrants that pass through the
Flathead on the way to their winter homes is mostly
over, it’s time to start thinking about buying Audubon
sunflower seeds and cleaning our bird feeders. Much
as I enjoy these last fleeting days of good weather,
I have to admit that I’m looking forward to hearing that
the bears have hibernated so that I can safely welcome
some old friends back to our feeders. When I
first started feeding birds years ago, a Black-capped
Chickadee was our very first visitor and they and the
other species of chickadees in the valley have become
regular visitors.
Chickadees are among the most frequent
and loyal feeder visitors. They are also some of the
tamest, often waiting patiently on a nearby twig while
I refill feeders and water. As members of the Paridae
Family, chickadees are closely related to titmice.
Both are small, energetic, social birds with short
conical, pointed bills. The species with crests are
titmice and those without crests are chickadees. Our
area is home to four species of chickadees: Blackcapped,
Mountain, Chestnut-backed, and Boreal.
Last winter we were fortunate enough to have Blackcapped,
Mountain and Chestnut–backed visit our
feeders regularly.
All chickadees have strong legs and short, stout bills
which are put to good use in feeding behaviors such as
hanging upside down at the tip of a branch eating a bud
or holding a seed with their feet while pounding it
open. Chickadees also store food in temporary caches.
Sometimes the food is cached and retrieved almost
immediately, as when they move many sunflower seeds from
a feeder and hide them in nearby tree bark. In this
case, the cache is used just
to help the bird get a large portion of the available
food for itself. At other times the caches are more
long-term, such as when seeds are stored in the fall for
use later in the winter. This behavior
which involves large spatial memory is crucial in their
survival in our harsh winters. Also key to their ability
to survive extreme weather conditions is their ability
to go into a state of regulated hypothermia, lowering
their body temperature from a day time temp of
107.6 º to a night temperature of 86 º. While in this
state of torpidity, they can still fly (somewhat weakly)
if the need to escape a predator arises.
All four kinds of chickadees found in the Flathead
have dark caps, black throat patches, and
white cheeks and prefer forest habitats. Males, females
and young all look alike. All are smaller than
sparrows and very acrobatic when feeding. Blackcapped
have buffy sides and Mountain can be distinguished
from Black-capped by the thin white eyebrow
and grayer flanks. Chestnut-backed is the most
brightly colored chickadee and has a rich reddishbrown
back and reddish brown flanks while Boreal
has a smaller white cheek patch and is more subdued
in color. Boreal is the shyest and the least often
seen of the Rocky Mountain chickadees.
All chickadees are cavity nesters and prefer
natural holes such as those created when a large
branch breaks off at the trunk or those made by
woodpeckers, but they will use wooden nest boxes
as well. This nest is also used in the winter as an
escape from the cold with several birds huddling together
to keep warm during cold snaps.
Currently, all chickadee species are plentiful
in our area but deforestation and development could
threaten their habitat, so urge your friends and
neighbors to save those trees and snags and become
bird watchers!
