This is Bird No.

Identifying birds by ear means getting familiar with each species' unique voice.

And that means learning the other voices in the ecosystem too, like the Fox Squirrels barks.

This squirrels alarm barks could at first sound like the calls of a red-bellied woodpecker.

But with enough practice, you can hear how the squirrels' barks are more throaty and more frequent than the woodpecker.

Here's the squirrel again. And the woodpecker.

That's not the only voice that could trip you up in the forest.

Take a listen to this cute little trill.

While it might sound a bit like a kingbird, it's really the chip trill call of a chipmunk, given when they're telling another chipmunk to back off.

In comparison, eastern kingbirds sound more shrill, increasing in volume rather than decreasing as they continue.

Here's the chipmunk again. And here's the kingbird.

Eventually, you might recognize each species' voice, like recognizing a friend. All it takes is time.
