26 Jul Gular Fluttering Is for the Birds
Gular Fluttering Explained
During hot summer days, everyone talks about gular fluttering.
If, by some odd chance, you’ve missed being part of such a conversation, here’s info on this important topic.
Now you’ll be able to impress your friends by taking the lead. For example, you might ask, “So tell me, what do you think about gular fluttering?”
Then be prepared for a flood of excited questions.
You might respond by offering a basic fact, such as: “Every species needs to maintain its body temperature.
When air temperatures are low (i.e., cold), birds generate heat internally by burning extra calories. This is easy because they have a large capacity for generating heat.
When air temperature are high (i.e., hot), birds must remove heat from their system. This can be difficult because heat reduction mechanisms have a small range of effectiveness.”
Pause here for a moment to let your friends absorb this.
“So birds vibrate their gular (throat tissues).
When they do this, they rapidly pump air back and forth in their system, thereby causing a very efficient form of evaporative cooling.”
Finally, if they’d like to know more, you can send them a link to this blog so they can see the above photos and . . . [ Drum Roll, please ] watch a video.

So the next time you see a bird with its bill open on a hot day, pause a moment to watch. Notice how the throat pulses, moving air.
Help Birds Tip
