Eavesdropping comes naturally to young song sparrows

...and prune their repertoire so their songs are more similar to their neighbors’. A song sparrow’s repertoire crystallizes at around 10 to 11 months of age and does not change. Beecher and his colleagues earlier proposed that eavesdropping and interactive singing are critical in song learning. However, th...

...ing water. According to the research team, this is similar to how humans can sense air flow with the small hairs on the face. Until now, it had not been demonstrated that the lateral line also aids in the tracking of odor plumes. "Odor plumes are complex, dynamic, three-dimensional structures used by many ...

Mule deer moms rescue other fawns

...responded to the recorded distress calls of fawns, similar to the responses elicited when coyotes attack fawns, with mule deer mothers responding to both whitetail and mule deer calls, even when their own fawn stood next to them. In contrast, the whitetail mothers responded only to their own species' call, a...

Moths mimic sounds to survive

The sound of proteins

...dual amino acids are expressed as chords, in which similar amino acids are paired. For example, the amino acids tyrosine and phenylalanine are both assigned a G major chord, but they can be distinguished because the notes in the chord are arranged differently. This means the resulting music has a 20 note ran...
