Fact of the Day
Songbirds practice singing in their sleep. By Bennett Kleinman Many musicians spend countless hours in rehearsal studios perfecting their tunes. But to some songbirds, rehearsing is also second nature; they’re even known to practice singing in their sleep. This behavior is similar to how a dog’s paws twitch while it snoozes, only in the case of songbirds, it’s the vocal muscles in the throat that experience subconscious movement.
Researchers confirmed this phenomenon by implanting electrodes in sleeping birds such as the zebra finch. While zebra finches are known to croon in a more methodical staccato style when awake, the birds were observed producing disjointed, sporadic notes as they slept, a behavior researchers likened to “learning a musical instrument.” Similar — albeit less common — behavior has also been viewed in great kiskadees, which produced louder and more aggressive tones in their sleep.

| Moles can smell underwater. | |
| By Tony Dunnell | |
| The star-nosed mole has an undeniably peculiar nose, with a snout ending in a ring of 22 fleshy, tactile tentacles packed with touch sensors. This nasal star is the tiny creature’s most distinctive feature, and it has a pretty incredible ability: detecting scents while underwater. Trying to inhale water is a very bad idea for mammals, but these semi-aquatic moles have circumvented that problem by blowing out small air bubbles from their nostrils onto objects or scent trails. The mole then quickly sucks the bubble back in, effectively “sniffing” the captured scents. They’ve been observed performing this bubble-blowing and re-inhaling sequence several times per second. It’s an ingenious adaptation that lets them forage in watery environments where ordinary sniffing would be impossible. | |
