Some interesting things happened in our back yard feeder area today. A mockingbird showed up and waddled on the ground looking for seed. He went up to a mourning dove and pecked at it, causing the dove to fluff up its wings. The dove then wandered back about 6-10 feet. I was indoors looking out a large bay window into our back yard. A ruby-crowned kinglet flew straight at my face. When he got about 1 foot from the window he paused in mid-air and flew back. It went this close before it realized there was a window in the way. Two yellow-rumped warblers started chasing each other in the air several times. This is the first time I have seen two such warblers. Do they have some kknd o f conflict, or are they starting a mating ritual? After chickadees (2006), titmice (2007), and nuthatches (2008), it would be something if my bird house was the home this year in 2009 to a nest of yellow-rumped warblers. So far I have seen no bird go into or out of the bird house ever since about a month ago when I saw a bluebird try it and fly away. Jim Blowers
