I've been writing down each species I see arrive at my deck feeders (two hummingbird feeders; one feeder containing Cole's Hot Meats; a feeder with Premium Sunflower Chips and a suet feeder which for the last three months contains Girard's recipe suet and for the first time in my life I'm learning how to melt lard! A 4x4 square only lasts 3 days!) for the last eight years. I see 15 - 20 species a day, it is a forest dominated by Douglas Fir in the area known as Sylvan, approximately 600 feet elevation.
Regarding Townsend's Warblers, a male has arrived each year (last arrival was 12.05.2016) and the last day I observed it was 4.03.2017.
