This is Not a Card About Giraffes Humping

It's actually about them HUMMING!!!!

Just when you thought giraffes couldn't get any cuter, we find out that the long-thought soundless giraffes actually hum. They hum!!! How cute is that?!
It's really not a card about them humping, despite what Google wants me to write about.

Listen to these guys hum their way through the night!

The humming is mostly still in the range of human hearing, but its really low at 92 hertz. Why hadn't this been noticed before? Who knows! But after recording at night for more than eight years at three European zoos, we now know that giraffes do communicate vocally as well. It was thought they might communicate in a range that is inaudible to human ears (like elephants) but that's not the case!

How else do they communicate?

Since giraffes have such great vision, they use behavioral and visual signals to communicate with each other in the day time. We're not yet sure what the night time sounds mean (it will take a lot of night vision recording and studying to try to link any sorts of sounds to behavior), but it's still very cool to learn something more about these cuties!!

Our silent buddies aren't so silent after all!!
