If you were to sit on my back deck for any length of time and observe the birds, it would quickly become evident that there are some who just can’t seem to get along.
For example, just about every time this little Kinglet stops in for a bite to eat…
…a Yellow-rumped Warbler darts down and dive bombs him off the branch.
And this bossy faced Robin, who often stands in his fighter pilot pose…
…allows every other bird to eat…except for the Bluebird that is, who constantly has to glance about to make sure the coast is clear.
And my Red-bellied Woodpeckers have become far less frequent feeders…
…now that my Yellow-shafted Northern Flicker has been patrolling the backyard borders.
And just in case you’ve ever wondered where the “yellow-shafted” part of his name comes from, take a look at the blurry flight photo below.
Pretty sure he is flying off to make sure his “Private Property” sign is still in place!
I know we tend to call these birds our feathered friends, but it seems they often see each other as feathered foes!

Here in interior British Columbia, I’ve noticed our Robins arrive about now and in a group–meaning, I’ll see a flock of them on the ground as though they’ve come from the South together in a happy family collective–and shortly afterwards the territorial wars begin, with the pairing off and sharp bark-like chirping and chasing, the vigilante-alert stance, the forever-indignant attitude, until FINALLY they’ve seen their newborns through to flight, and can F I N A L L Y just be Robins, for god’s sake. They just get so bossy. I find them rather tiresome, I must say. Very interesting blog. I always like it.
I enjoyed your comment. You weave words together in a way that is enjoyable to read. 🙂
