Take a Deep Breath

As promised in my HEN story of a few days ago found by CLICKING HERE-- the strange call of the long tailed Grackle.

I learn mostly about animals by observing their behavior. I ask questions wherever I can, in fact, I run the risk of being that annoying question person. But I do have enormous curiosity about everything... Of course it can led me to Google a little and read up in books. But I don't have much spare time.

In this case, I've observed a strange call in the long tailed Grackle. Only see it in the males (females are brown, males are the irridescent indigo blue-black you see below). I assumed it was a kind of mating call, since many males puff up what they've got to impress a female. But while sometimes another grackle is nearby, it's usually another male. So one might assume that it's a fighting posture -- again, another reason to make ones self bigger. But I've never witnessed a fight ensue. The call is also different. If you look here as the grackle comes up behind the chicken, it makes a mechanical sound, like someone's turing on a loudspeaker to test it before an announcement.




Or you have this other sound... more of a wind up noise. Sorry in advance for the wind in the microphone.... but I got a better shot of one doing it by complete chance.




Both time the bird inflates fully and opens it's beak, the noise comes out and he deflates to less than half the size, then... nothing. I've also tried to figure out if this only happens at certain times of the day or the year, without much luck... Anyone out there with answers? Clues even?

Interesting, the only bird I've ever seen inflate like that is the grouse, and that's just more in the chest. There are probably other birds that do something similar. But that guy really puffs himself up, wow!

Neat Sydney... I've never seen that before.

I never become half the size after my mouth has been open.

OH RENEE! I think you may have just won best comment of the year with that one!!!

Meb -- I hadn't either, til I moved here. Isn't it wild?

Crochet Lady -- I wonder if what the grouse does is what the grackles do, only all over... I still don't understand why.... They aren't songbirds, but I think they make other noises without the big puff...

They'd all make great sax players.
