It was a decidedly Chestnut-sided morning for Twan recently, with this cooperative Chestnut-sided Warbler (Setophaga pensylvanica) enjoying the rising sun. How can you not love these birds? The fact they make the journey all the way from places like Costa Rica, where RTPI works on the ground to understand their wintering range, behavior, foraging and more, to our yards is truly astounding. Their good health is our mission year-round!
