I was recently in MI and heard one calling at 4 in the morning. There was no response and after about 10 15 minutes it stopped. Here I know of several RTH nests an I'm always oogling them to see if a GHO is hanging around. But I don't know if they would do that during the day? These are all nests in bare deciduous trees (oaks). Also the ones I know of are still in use by the RTH's but they don't hang around them this time of year. How would a GHO know if a nest is abandoned or not?

They use abandoned crow,hawk and eagle nest as their nest as their own. Or if a cavity is big enough, they'll use that too. They nest in January and February, when snow is on the ground! Here's another fact, when a female Great Horned lays on her eggs, with snow on the ground, she can transfer/produce 98 degrees of warmth to her eggs! The chicks can take about 30 days to get out of the nest. So just listen at 7:00PM or later for them. I personally had more luck with them in the morning. Calling, I think their more active at morning. Last year, I had one on a phone pole for 5 straight days. Every time I left my house at 6:30 I the morning, he/she was just sitting there on top of the same pole everyday. One day I got to see him/her fly off the pole into the field catching a mouse or vole. Just have a eye out for them for this upcoming New Year! Go Bucks! Beat Bama! HappyEarly New Year. ______________________________________________________________________ ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
