Two male Pileated Woodpeckers battle for supremacy. Photos by Anders Gyllenhaal
We heard the clamor from our woodpecker’s nest and instantly knew something was up. The bird’s usual call was replaced with a high-pitched, staccato screech and both the male and female birds leaped around their tree as if the place was on fire.
Last week, we wrote about the idyllic life these two Pileated Woodpeckers created within a few steps of where we are camping. This week, we got a reminder that nature is unpredictable and sometimes violent. By the end of the week, the pair were forced out of their nest just as they were trying to start a family.
The cries we heard that day were the precursor to an attack from another Pileated Woodpecker who wanted to take the place of the male. We scurried over to see what was going on just as an attack was about to begin. The two male birds jumped from one branch to another, howling furiously. Then they tumbled to the ground as if in a western, falling head over tails as they wrestled. We though the duel might be over, then the two males flew to the top of the nesting tree and began circling each other while trading jabs and squawks.
Pileateds are the largest woodpeckers in North America, more than a foot tall with a wingspan of two feet. They are powerful birds with large claws and sharp beaks. All of those tools came into play as these two battled for the advantage.
Finally, our original male took a powerful swipe at the intruder, who then flew off in what turned out to be the end of the threat. Both the male and female climbed up and down their nesting tree, ready for another assault that never came. Eventually, they settled down and went back to readying the nest they’d worked on for the past two weeks.
Here’s how it looked in a video:
Of the 37 species in the Eastern U.S., the male Prothonotary is the only one that glows. His head is a saturated yellow-orange, earning him the nickname “Golden Swamp Warbler.”
A fascinating new book by Jennifer Ackerman, The Bird Way, A New Look at How Birds Talk, Work, Play, Parent and Think, says birds have a rich social life. She says the language of birds can be complicated, emotional, and has its own syntax. This book suggests that birds will even lie at times, implying a level of sophistication far beyond what we always thought.
Birdsongs are primarily about mating and defending territory, but exchanges like this one that seem more like household conversations are part of the repertoire as well. The Cornell Lab’s Handbook of Bird Biology, the bible of bird life, says bird pairs of all kinds are constantly seen singing duets, chatting back and forth and sometimes simply working on their relationships by staying in close touch.
Robert Rice, a veteran bird scientist who spent his career with the Smithsonian’s Migratory Bird Center, explained what happens: “They can eat so much fruit, it ferments in their gut and they go wobbly for a while,” Rice said.
It’s a magnificent sight, one I assumed I’d miss this year with our limited mobility. But the other day, wandering through the trees not 50 feet from our home, I noticed what looked like a new arrival. It was the first of a flock of Cedar Waxwings that gradually became an avalanche, all collecting insects as if their lives depended on it.
As birders all know, the more people get interested in birds, the more likely they are to want our state and federal government agencies to protect them.
First it zigged and zagged along the edge of the shore, lunging for prospects as it followed its own obstacle course though the water. Then, apparently unhappy with the results, it lifted off and headed to a new spot. That’s when the heron spotted something near the surface of the water.
