The crows say 'Lololol.'

Here’s another recording of a crow making a kind of coo or warble. They’re very expressive given how harsh their “normal” noises are.

That movement the crow is doing seems odd. I love crows.

My niece just posted a video of a raven that hangs out at the Anchorage Zoo. He’s making a sound that is exactly like a drop of water hitting a puddle. He’s well-known at the zoo, and also imitates other animals as well.

The crow says ‘lololol’?

I think it’s laughing at you…out loud.

Also, the laugh of Phyllis Diller/Agnes Skinner.

I agree that it sounds like the crow is mimicking something. The neighbors of some friends had some kind of bird with this ability, and we would hear it often when we were in the friend’s back yard. One of the sounds seemed oddly familiar. It wasn’t a word or a sound that you’d associate with humans, like a whistle, so we thought it might be part of the bird’s natural vocabulary, until we realized it was the bird’s flawed attempt at mimicking the ringtone of the owner’s cellphone.

I lived in an apartment complex that had several families of mockingbirds living in the trees in the middle quadrangle. There was also one tenant with a very hard to start British Motors car that generally took seven or eight tries at cranking over before it would finally catch. One day I heard that noise much later than the tenant usually left for work, looked outside and the car wasn’t there, but a mockingbird was in a nearby tree making a pitch perfect imitation of the noise. I laughed and laughed.

I have heard mockingbirds mimic the sound cats make and sometimes almost barking like dogs. They are great parrots (heh).

The video after yours was a guy talking about crows’ sounds.

He talked about the cricket noise. He said they aren't sure what it means but they think it means something "Go get him! I got your back."

He mentioned they can make a bell-like noise, but didn’t say what it meant.

Interesting video, only 3 minutes.

Crows are mimics, and can actually be taught to talk.

In SE Alaska, I saw a few that would make the sound of a pebble falling into water. They would only do it flying upside down. They would go 4 or 5 normal flap of their wings and then kind of swoop over onto their backs to make the BU-WUMP sound, correct themselves and continue flying.
