As compared to a red winged black bird.
We had scarlet tanagers passing through earlier in the spring and, as usual I was captivated by their intense colour.
This is a bird that should make you do a double take.
On the wintering grounds in South America the Scarlet Tanager joins mixed species foraging flocks with flycatchers, antbirds, woodcreepers, and resident tropical tanagers.
The female Scarlet Tanager sings a song similar to the male's, but softer, shorter, and less harsh. She sings in answer to the male's song and while she is gathering nesting material.
