Did you know that giraffes, often a very quiet animal, hum in their sleep late at night? Zookeepers involved in the study were even surprised that researchers picked up a low humming noise from their giraffes.
Researchers spent hundreds of hours recording sounds in the giraffe’s enclosures and in each zoo at least one giraffe was separated from the herd.
Although the sound recordings tell us that giraffes do have more vocalization than the grunts and sneezes that keepers hear during the day, now scientists may go further to understand if this is a communication method or if it is involuntary like snoring or talking in your sleep.
Do you want to learn more about giraffes, or animal sounds? Here are two Arbordale books that would be a great start on the topic!
The Giraffe Who was Afraid of Heights
Imagine if the one thing that keeps you safe is what you fear the most. This enchanting story tells of a giraffe who suffers from the fear of heights. His parents worry about his safety and send him to the village doctor for treatment. Along the way he befriends a monkey who is afraid of climbing trees and a hippo who is afraid of water. A life-threatening event causes the three friends to face and overcome each of their fears. The “For Creative Minds” section includes fun facts and animal adaptation information, a match-the-feet game and a mix-n-match activity.
Sounds of the Savanna
From the first light of dawn until the sun sets at night, the savanna is alive with noise. A lion roars in the early morning, a young baboon shrieks to warn others of danger at noon, and a young mouse squeals at dusk. What are the animals saying and why? Animals communicate in many ways; explore the thriving African savanna as its inhabitants “talk” to one another throughout the course of a day.
And…Look forward to next year when we see what really happens at night in the zoo! Midnight Madness at the Zoo coming February 2016!
