Sitting in my home office yesterday, working on the computer, when I hear this high pitch whistling going on. Hmm I know that sound! I rush outside and run into my Wife who also recognized the sound. Around to the chicken coop we go. Sure enough all the hens have crowded inside their smaller covered run. We look around for the source of the sound and sure enough there is a huge bald eagle sitting about 30 feet up in a tree. My Wife is also worried about our cat, so she starts running around the property looking for him. She finds him, and he is obviously in a very excited state. (You can tell if you have owned cats before). So now I wonder if he was after the cat, or the chickens? It flew away within a few minutes, as I suppose our presence may have disrupted his hunt. Usually the eagles are all down by the river, (1 block away) feasting on salmon carcasses, but the recent heavy rains have caused the river to swell, and has washed the carcasses away. Never had an issue with them before, but it is winter, so I expect the eagles will be looking for alternative food sources. I hope like heck it's not back again today. You can't shoot them by law, so how do you protect your animals from them?
