Animal Hearing Series: Cows

This post is part of a series I began with Lizards. I'm really interested in how well animals can hear.

Cows are my favorite animal. Don't ask me why, I just love their funny expressions. But it's surprisingly hard to find information about how well they hear, compared with my previous posts on lizards and snakes.

According to this page on the Louisiana State University website, cows can hear in a range of 23-35,000 Hz. Compare that to a typical human range of 20-20,000 Hz (or 64-23,000 on the previously linked website).

However, as mentioned in this article, cows have trouble pinpointing sound. I can sympathize with cows on this one, but I think they still manage to do better than me; they can pinpoint the sound source within 30 degrees, while a typical human can narrow it down to 5 degrees.
