Hi Sean

Your right - these birds have seen a raptor. They will freeze till the danger 
has past. Most all raptors need to see motion to pick out their prey. The hawk's 
eyes have more motion pickup ability at the loss of color perception. Potential 
prey has to move for them to pick them out of all the rest it sees. 


Even though you didn't see the danger - they saw/see it - or, they might also 
hear a danger call from another bird. And the best thing they can do to become 
invisible is freeze - or have no motion. It usually takes some time, even after 
the danger has gone, for them to presume their doings. So as colorful as a bird 
is, Raptors will usually not detect them until they move.

I have found, birds find much more danger to them from above not below. Walking 
animals - or as the Indians say - " two and four leggeds " pose far less danger 
to them than avian danger.
 Hope this helps........Paul Carrier
