Forgive me if I led you in the
wrong direction a while back. What with all the talk of Hummingbirds leaving and other birds
migrating to warmer climates, you may have gotten the impression that this area
is empty of birds until spring. Nothing could be farther from the truth, and a
look out your window may be enlightening. Without a doubt, there are more birds in
north Texas in the fall and winter, than in the spring and summer.
True, some birds (like Hummingbirds,
Buntings and Swallows) have left for their annual winter haunts in South and
Central America. Other birds (like Goldfinches, true Sparrows, Juncos and
Kinglets) that spent last summer in northern regions, however, are arriving in
north Texas as we speak. To them, this IS south – our comparatively mild
winters agree with them.

In actuality, many of the cool
weather birds are already arriving here. Even at this early date, a few Juncos,
Kinglets and Goldfinches have been seen. Depending on weather, however, the
bulk of them may arrive late November. Cedar Waxwings normally arrive here a week
or so after that. True Sparrows, like the White-throated or Chipping Sparrows, are
already here in throngs.
Sadly, wild birds have a high
mortality in cool weather – it varies among species, but can be as high as 70%
of the first-year birds. This is mainly from exposure to the winds and weather,
coupled with a lack of fresh, energy-producing food. That's why birdfeeding in cool weather is so important. Birds, like us, also want to get
out of the weather, especially at night . They seek out “roosts” for the night. Roosts can be almost any
warm, protective space. Some species, Chickadees are one, huddle together in a
mass, sharing body heat. Birds need birdbaths in cold weather too. At first, this seemed odd to me too, but not after
discovering why they fluff up their feathers. The fluffing creates tiny air
pockets, which insulate birds’ bodies quite well. Dirty feathers, however,
won’t fluff up. So birds need to bathe in the winter (the actual bath takes
only about a second).
Bathing, warm roosts and fresh
food are what birds need in cool weather. North Texans have been doing a good
job of providing these basics, so we continue to have more birds here in cool
weather, than the spring and summer.
