Immature Avian Antics



For nearly three decades we have fed and observed birds that inhabit our surroundings. Living surrounded by forest, we don’t have that many species around us, as we might have, if we lived near open fields. Numerous species migrate through in the spring or fall, but only a dozen or so are regulars. Of them, many keep to the woods, so about a half dozen are consistently at the feeder, and those are the ones we watch and get to know on a day-to-day basis. 

Over these decades, therefore, we’ve become quite familiar with the behaviors and personalities of our resident avian companions. I can watch a titmouse, for example, and almost predict what it will do next—how long it’ll sit at the feeder, how many seeds it will grab, how it will interact with another titmouse there, how and where it will fly after feeding, etc. Their behaviors will vary with the seasons, but again in a quite predictable manner. It’s similar to how we observe and interact with a beloved family member, when their habits and quirks become deeply ingrained in us.

This level of familiarity becomes such a part of our routine that we hardly notice it—like the way in which we prepare our morning cup of coffee or tea. So when something comes along out of the ordinary, it grabs our attention. When I reach for my favorite tea cup before breakfast, and it’s not where it’s “supposed to be,” I’m rattled a bit. Dammit! Where did my wife hide it? My attention is momentarily and completely drawn to this unexpected event.

Similarly, in mid-late summer our attention often gets seized by a bird that is behaving unusually, for its species. What? A chickadee doesn’t normally do that! Why is that wren acting so weird? What’s gotten into the mourning dove? Something about their demeanor is odd and we notice it. 

As our awareness is drawn toward the bird, we then might notice that its actions are not at all well-coordinated. It doesn’t seem to be adroit in its behavior. It flutters around kind of aimlessly, as if unsure what to do next. Its attention is diverted by most anything. It seems to have no specific intent in mind. It may clumsily fly to a tree branch but misjudge how to land—finding itself upside down, clinging confusedly to a twig, rocking back and forth.

At this point we realize that we’re watching a newly-fledged youngster. Its flight is erratic. It’s not sure what to consider as food, so it pecks at most anything in front of it—most of it obviously inedible. It frequently drops to the ground, unaware that it’s far more vulnerable down there. (That’s why we keep our cat in the house during the day.) Adult birds are perky and fun to watch and their behavior is deliberate. Fledglings are simply hilarious and you never know what they will do next. Our familiarity with the ways of adults does nothing to prepare us for the antics of the youngsters.

This ungainly behavior doesn’t last long. Animals in the wild must mature very quickly or they perish. They don’t have the luxury of extended parental care. A baby bird transitions from egg to fledgling in about two weeks—fully the size of its parent. In another few days it’s on its own, and we are no longer able to chuckle at its awkward bearing. They grow up fast!
Some youngsters quickly disperse and go off to lead their own lives. Unable to follow them into the forest, we’re not sure how well they fare. I don’t think we want to know. We’ve watched their parents work so hard to bear and protect them, that we hate to see their offspring die so soon. The mortality rate for songbirds is high—more than half die within the first year. 

Some youngsters take another route and hang around for a few months, helping mom and pop raise subsequent broods, before they attempt to go it on their own. Maybe that’s a surer way to get started in life. But unlike teenage kids, they won’t be goofing off, watching TV, sleeping in, or playing video games. The life of a songbird is not one of leisure, even when we provide a feeder for them. Bees might have a reputation for being busy, but birds are no slouches.
