Impression Evergreen

Song Sparrow In the soggy marshland surrounding Evergreen Lake he sings his heart out. His sweet music includes twenty different tunes and at least 1,000 improvised variations so it’s no wonder they call him the song sparrow. Full of complex rhythm and emotion, his colorful vocalizations are used to attract females and defend territory. His unique, prolonged melody distinguishes him as a neighbor rather than a stranger. This common sparrow is an adaptable bird whose behavior and appearance is extremely variable and unpredictable. He is found throughout North America but individuals from different regions look completely different from each other. In our neck of the woods, the song sparrow is described by brown, heavily streaked plumage, a mottled back and a white throat. His face is gray with a dark eye line and a white jaw line while his reddish crown has a neat gray stripe. The female builds a nest that’s usually concealed somewhere near the ground but he does help colle...

Spotted Towhee Rustling through the leaf litter below the dry scrub brush that laces the steep, Colorado foothills is where you’ll find a hefty sparrow known as the spotted towhee. Such beautiful birds, the males have a white belly, orange sides and a black head, throat and upper parts. The back and wings are flecked with white spots while the red eyes are the defining characteristic. During the early spring, those males creep up to the top of the thicket and sing all day long while trying to attract a mate. In the breeding season they eat mostly insects but they’ll also dine on acorns, berries and seeds. They’re nest cup is built deep inside a sharp briar and usually concealed somewhere near the base of the shrub. A close cousin, the eastern towhee, used to be considered the same bird as the spotted towhee and in the past they were called the rufous-sided towhee. During the last ice age large ice sheets split the continent down the middle, isolating the separate birds into ea...

American Kestrel The American Kestrel is North America’s smallest and most widespread falcon. This pocket-sized bird of prey is extremely adaptable as she can be found anywhere in the Western Hemisphere from Alaska to the tip of Tierra del Fuego, Argentina. The most colorful of all the raptors, she is distinguished by brown wings as opposed to the male’s beautiful slate blue. Perceiving her identity is practically unmistakable while she’s perched on a small pine scanning the grassland for her favorite food; grasshoppers. She owes much of her success to a broad diet that includes almost any insect, lizards, snakes, mice and voles. She’s a ferocious predator that has the ability to take red squirrels and small birds especially sparrows while still on the wing. She’s the fearless matriarch of a tight-knit group as both parents are equally active in rearing the young. Often, the whole family will go out on a hunting foray as it’s an effective way to teach the fledglings how to s...

Vesper Sparrow So far this summer, the bird I’m seeing most frequently in our foothills is the decidedly nondescript vesper sparrow. His name is Latin for ‘evening’ a time when this bird loves to sing. At first glance, this stout sparrow looks rather drab but if you take the time to look closely, you’ll discover that he’s really quite beautiful. His overall light-brown color is intensified by a bright orange patch on the shoulder. A pattern of dark streaks helps him to blend perfectly into the environment. Barely visible in the vast meadow to even the keenest observer, his exuberant song is what gives his presence away. If you happen to cross paths with him, he’s not shy and he can be photographed rather easily. He tolerates a friendly encounter and watches curiously with his white-ringed eyes. He hops down the dirt trail searching for his favorite foods, insects and seeds. If you get too close though, he will flash his white outer tail feathers as he alights to a nearby m...
