The last few years a barred owl had been spending its winters near this site. Last year a second barred owl showed up as well and as usual they disappeared for the spring. Then for seemingly one day a great horned owl showed up. But it was not to be seen again, until now (if its the same owl). I had noticed the absence of barred owls this year, and this great horned owl if taking up residence could help explain their absence. Great horned owls will prey on barred owls and any other smaller owls. The screech owls nesting box is about 1/4 mile or less away. Just as the screech owls had to avoid being preyed upon by the barred owl(s) they will have to avoid this great horned. Anyway the female screech owl has been regularly spending the day in her box including today.
