The Mighty Chickadee In The Colorado Forest

The Cornell Lab of Ornithology describe the little bird that frequents most of Canada and North America as "universally cute." But Kailen Mooney, while a doctoral student at UC-Boulder in 2006 proved this "cute" bird can also save the magnificent pine trees. He found that these mountain chickadees , along with other songbirds such as the red-breasted nuthatch and the pygmy nuthatch who are year-round residents of the Colorado pine forests can change the "flavor" of a tree. Mooney put about 300 insects and spiders on some ponderosa pines in Colorado. Then he covered the pine with netting so the chickadees and his friends could not eat the aphids and caterpillars. While dining on the branches the tree, like other plant life, these insects cause the tree to give off an odor. When the birds ate the insects, the tree's "flavor," or odor, which Mooney explains is a chemical called terpene, changed. But wait there are three other actors in this environmental tragedy. In walk the bark beetle, the squirrel and porcupine. They smell a change. A whiff they dislike. Like so many of Aesop's tales, the largest forest inhabitant once again is saved by his tiny companion. But the play does not end here.

Home In The Hollow

Often a dead or dying tree with a gaping hole appears to be ready for the ax. But wait, when that tree is burned (through prescribed burning programs) or felled to make bike paths, roads, or driveways, wildlife suffer. We all have read some of the prolific children's literature  featuring homes in a hollow tree for a bunny, squirrel, raccoon...and the list goes on to include the other forest mammals-deer mice, martens, fishers, porcupines, weasels, and black bear. ( One of Jean Craighead George's first nature books was titled, Hole In The Tree. Warm blooded forest denizens are only a few of the wildlife that depend on tree hallows. Songbirds like the chickadees and woodpeckers also make their own cavities in trees and white-breasted nuthatches use tree holes already formed. For the ubiquitous chickadees throughout North America dead or fallen trees offer safe nesting places.

Taking this one step further, one might ask how do these little black and gray and white birds affect our environment? Chickadees eat bad bugs year round. Who does the bark beetle fear as he munches his way from the western states to the East at an alarming rate? That's right. The little chickadee.

Share this gentle environmental nursery rhyme with a child. Then talk about how this tiny songbird has become a leader in the fight against global warming. This friendly backyard bird is fun to watch and eagerly comes to feeders filled with black seed oil or thistle. With some patience, you can train them to eat from your hand.

Tiny mountain pine beetle,

I wish you could see

Just one needle

Each one is green, green, green

But you are hungry and mean.

You nibble a path on your way

Green to red

Then all are gray.

A New Year?

Did you ever wonder what life would be like without milestones like birthdays or holidays? Somehow the natural world celebrates each day with none of our candles or bows. Its greeting is the sunrise. It's party goers are the squirrels swinging from a branch to reach the bird feeder. It is the chickadee and titmouse vying with the blue jay for a morning snack. It is the deer cautiously grazing on what green is showing; or the red headed woodpecker knocking out his welcome call.
