Saw-whet responded to my whistling of the "toot" call .... this is the 
advertizing call on most tapes.... a single bird responded five times, each time 
with the "scream" call followed by a long period of silence.

Hi Jim,

 - What is the effect of frequent noises and/or disturbances on the birds 
while they're attempting to roost?
 - After finding an owl at a particular location & passing on that 
information, are you confident that all birders will act respectfully towards the bird?

Steve Huy: Does your experience with saw-whets (and birders) suggest any 
answers to the above questions?
