Welcome back everyone! Avian life is still quite active at the little farm pond, and I haven’t forgotten my promise to identify a few more of the singers we heard in the first set of recordings. Here are today’s featured singers:
First, let’s listen more closely to a feisty little bird whose song I describe as a “sonic explosion” – the House Wren. He’s the one in the picture at the beginning of this post – a small, brown bird with a big attitude.
His song is an emphatic jumble of notes too rapid and complex for mere humans to fully comprehend, and impossible for us to imitate. And how can something so small be so loud? I once sang with a choral ensemble at a garden party on someone’s private property. A single singing House Wren in the garden overpowered the entire human chorus!
House Wrens are cavity nesters that will happily take over one of the Bluebird or Tree Swallow houses near the pond, but this little guy seemed to be going in and out of a hole in a tree. It looked like this might have been a woodpecker nest cavity at one time, but he was loudly claiming it for himself and his potential offspring. Male House Wrens will stake out more than one possible nesting location and fill each with twigs. The female makes the final choice, though, and I don’t think she found the tree cavity to be acceptable.
Now let’s turn our attention to the other species whose song is obvious in the recording – the Warbling Vireo – whose excited, speedy song usually ends with an emphatic upturn. This rather small small songbird is typically found up in the trees along rivers, lakes, and ponds. “Found” may not be the most accurate term, though, as it implies that you’re actually going to see these birds. Like the House Wrens, they’re much easier to hear than to see.
Warbling Vireos do indeed seem to “warble,” and their songs are very different from the Red-eyed Vireos I hear all day long in the summer woods. I love the upturn that often occurs at the end of the song – it sounds like a question has just been posed.
I didn’t realize until I looked closely at the sonogram for this recording that each statement of the song is a little different. It’s difficult to discern because the song is quite rapid, but here’s what it looks like if I take out the other birds and the pauses between the songs. Now if only I could hear fast enough to catch every bit of the detail!
I’ve never heard so much Warbling Vireo song around the pond before! Eventually, though, this dynamic little soloist decided to move across the meadow to one of the university’s research ponds up the hill. I can only hear him in the distance now, but I’m glad I had the opportunity to observe him up close.
And that brings us to a third species heard in the recording – the Eastern Meadowlark – a species you might not associate with a pond. They’re here because of the large meadow areas that adjoin this pond. Meadowlarks are fairly large and quite striking, but it’s amazing how well they disappear into the color and texture of the meadow. Like many other species, they are often easier to hear than to see.
This next recording is one of the two Meadowlarks that were close to the pond, and we’ll hear the other Meadowlark momentarily.
Meadowlarks aren’t singing as much now as they did in the spring, and you’re more likely to hear one of their harsh, “rattle” calls. The first couple of times I heard this sound, I had no idea it was a Meadowlark. When I actually watched one make these calls, I remembered them from that point on. Here they are:
There was second Meadowlark a little distance away from the far end of the pond, and he was singing a somewhat different song. My last recording for today is that Meadowlark surrounded by some of the other bird songs we’ve enjoyed by the pond.
The birds have established their territories and most are feeding nestlings. Some already have noisy, begging fledglings and some species will nest again and raise a second brood. On our next walk, let’s listen to how birds like the Song Sparrows define and defend their territories through song. Perhaps we’ll be able to listen to some of the begging babies as well. In the meantime, listen to the birds in your favorite spot to see and hear – what you can notice about how they are using song to define their territories. Let’s check back with each other soon!
