I've been hearing a nocturnal bird near my home for a month now and suspected some sort of owl. All week a very large owl has been flying down and landing under the pine trees that line my property. Tonight I had binocs ready and have verified its a Great Horned Owl. I just searched the internet and found the exact nocturnal shrieking sound that its been making. Just wanted to share. I'm very excited as I have always loved owls but they are hard to spot. Melissa Walker Murphy Pulaski, Giles County, Tennessee
