Thank you for the info.
I wonder how frequently Barred Owls, not Spotted Owls, will move into areas where Barred Owls have been killed?
Do Barred Owls expand their territories in lower densities?
Does anyone know a source showing these sites on a map... and the two other sites mentioned in the article where owls have already been culled?

I was listening for and heard nothing about them using controls... and why these three sites were selected, and if the control sites exist (I'm betting they don't), how were they selected and how do they compare to the areas where the owls will be culled.... I'm bringing this up because I see real potential for some erroneous conclusions to be drawn unless these details are brought to the forefront now and kept there. An "experiment" is only as good as its design.... and to call this an actual "experiment" is probably quite a stretch.... therefore, it was a red flag to me that is is officially being described this way. <---

with no barred owl hunting. Scientists will see if spotted owls move
back into areas where barred owls have been killed. The four study areas add up to 1,207 square miles, which amounts to 0.05 percent of the
northern spotted owl's range.
