The birds and bats

[jotwo2003]

IIRC in the POA film we see crows and bats.

I think the crows were in the pumpkin patch by Hagrid's hut and they 
fly into the air when we hear the fall of the axe and think Buckbeak 
has been executed. 

I think we see a flock of bats fly past Hr and H when they have 
travelled back in time and are watching themselves from the forest.

Are there any other occasions where we see bats or crows?  Also do we 
really see the bats flying and then see Snape going into the willow? 
I read somewhere that we do.

I'd be really grateful for help with this.
