North American Chipping Sparrow

Birds are popular on blip so thought I would try my hand at a bird photo. It was 18 F/-8 C this morning, and next time I try this will want it to be warmer. Using a guide to birds of eastern North America, I believe this is a Chipping Sparrow.  Mounted camera with 70-200 lens on tripod about 8 feet from the feeder, and tripped with wireless remote. It was completely overcast so tried using TTL flash and also without flash. Color and contrast were better using a flash, and this photo used flash.  The flashgun spooked the cardinals but not the other birds. Next time need to observe bird behavior for a longer period of time prior to positioning camera. Optimum position and angle at the start will save time from sitting in the cold.
