The crow, the fence and the bridge

As I approach
The crow jeers
CAW CAW CAW!
Mocking bird

One more step

I get one frame
As it perches there
On the fence
The bridge beyond

One red eye glaring

It ducks
Leaps
Spreads
Lifts

Click!

That will be the one
But I click again
Taking a third
Which will never be shown
