The birds of Cedar Mill
Those little brown and black birds!
by Lauretta Young

A customer called to set up a birdwatching tour as a gift to his teenage daughter. He wanted to get her outside, away from the lure of her many electronic devices, and thought that learning about something ecological might appeal to her interests in “biology.” I asked what kinds of birds she would enjoy seeing, (thinking—would she like to go to a lake to see migratory waterfowl or maybe a forest to see the warblers streaming into town to eat insects). He said, “Oh, she’d like to see some pretty birds.”

This was a challenge since most birding guidebooks are organized by either the species of bird such as ducks or by habitat. I don’t have a book, nor do I have a file in my brain, yet, organized under the term “pretty birds.” So we organized a tour to pursue brightly colored and lively birds; my best interpretation of pretty.

On the opposite end of the brightly colored spectrum we have the many plain black and brown birds—which may account for why people new to birding might think this hobby is uninteresting or difficult. In birding books brown sparrows—which can be difficult to distinguish from each other—are often collectively referred to as “little brown jobs” or LBJs.

In Cedar Mill, we have only a few “black birds.” For example, there are the ubiquitous European Starlings (which many biologists call “the flying rat” due to their tendency to be in huge flocks which create a lot of bird waste wherever they happen to go). Holly trees, grapes and other crops may be damaged by the waste they leave behind while roosting. They also eat other birds’ young and are said to be responsible for the disappearance in the Tualatin Valley of the bluebirds, which used to be prominent in this area before the 1960s when the Starling population exploded. On the other hand, like the American Robin, Starlings do have a useful function—notice them hunting for harmful Crane Fly larvae in your lawn.

Other than Starlings we have a few other mostly black birds. For example, Turkey Vultures may be recognized soaring high overhead with a characteristic shallow V shape, or dihedral, in wing posture. You may also notice they tend to rock and tilt unsteadily in the upper air currents, creating a very uneven flying pattern. Compare Hawks and Eagles which hold their wings in a flatter posture when soaring. Turkey Vultures are migratory; we see them generally in the spring and summer.

Another black bird is the Red-winged Blackbird, common in our Cedar Mill wetland areas. The male is notable for the red and yellow epaulettes on the shoulders of their wings. The females of these birds are not black but a mottled and striped brown, which is often confusing for new birders who wonder what those brown striped birds were at their feeders!

We also have Brewer’s Blackbirds, which are smaller than Starlings, mostly black but their eye is whitish to yellow. Our final black bird is the Brown-headed Cowbird, which is migratory and not found year round here. These are smaller than the Brewers, have a stouter beak but the males have a brown head. The females, like the female red winged, are mostly a dull brown. These birds are “famous” in the birding world for laying eggs in other bird’s nests so that the other birds raise their young. So if you are truly lucky you might see a bunch of baby robins with a very funny looking “sibling” hanging around which the robin parents are also rearing—the cowbird intruder “egg” that hatched with the robin eggs! Interesting reproductive strategy!!

Crows and Ravens are another group of blackbirds that we will review in the future. And eventually we’ll review the variety of other little brown jobs in Cedar Mill. On rare occasions I have seen a Yellow-headed Blackbird in a local marsh, but usually those are found further east—so keep your eyes open for these less common Blackbirds. Not all black birds are the same!
