nesting season has officially begun. Dr. Clara laid her first egg this morning. She will now lay one egg per day until her clutch is complete. Bluebirds raise several broods in a season, usually three in my yard. The clutch size can vary with fewer for the first and third and up to six in the second clutch. It is rainy and windy today, so the sparrow spooker will go up only tomorrow. Mine is homemade, two dowels on which I attach streamers made from a birthday balloon. They are supposed to keep House Sparrows at bay. HOSP cannot see well and get spooked by the shiny flappy things and stay away from the box.
