You may know that the recently-released UltraVox XT 3 is used to study ultrasound vocalizations, especially in rodents and bats. But the fact that it analyzes full-spectrum sound, together with the filter options and cool features like the spectrogram and the automatic call detection, makes it ideal for analyzing bird calls.

But what actually makes a wolf cry? Is it because it misses its friends? Or is it simply something its body tells it to do?
