Activity #1: Two birds I can tell apart by shape are the great blue herons vs. bald eagles.
Activity #2: I chose to identify birds with the color white. While using binoculars at an estuary, I spotted a heron-like bird that was definitely not a great blue heron because it was all white. With the help of Merlin and my field guide, I discovered it was a great egret. I also identified a black capped chickadee and a ring billed gull. All 3 birds have white coloring.
Activity #3: Birds at my sunflower chips feeder today include black-capped chickadee, American goldfinch, and dark-eyed junco. Wading, fishing birds included the herons and egrets, and an osprey was hovering before diving at the estuary.
