Today a FOS Yellow-throated Vireo was singing in the backyard. They have nested in the maple trees there in past years. An hour or so later a FOS Red-eyed Vireo was singing on the opposite side of the yard at the edge of the woods. About 10:00 this morning my pigeons got their first encounter with a predator. I have had the four pigeons for about 2 months now. They were just out of the nest when I got them. Each morning I turn them out to fly. After about 15 minutes of flying they perch in the top of a large walnut tree just above their loft. They had only been perched about 5 minutes when suddenly they burst from the tree in unison flying away faster than I had ever seen them fly before. In a couple of seconds a Sharp-shinned Hawk came gliding over the tree with some of my resident martins dive bombing it. It was too occupied with avoiding the martins to chase the pigeons. After the hawk left the pigeons circled for awhile before returning to their perch. The Yellow-throated Warbler that showed up here about a week ago is singing every day in the White Pines at the edge of the yard. Yesterday there were three of them having a battle. I'm not sure whether it was two males fighting over a female, two females fighting over a male or a pair defending their nesting territory. The battle went on for about 10 minutes before one of them left the yard and peace returned. Spring is always fun. Roger Mayhorn Compton Mt
