The Cornell Lab of Ornithology comments: “The only completely red bird in North America, the strawberry-colored male Summer Tanager is an eye-catching sight against the green leaves of the forest canopy. The mustard-yellow female is harder to spot, though both sexes have a very distinctive chuckling call note. Fairly common during the summer, these birds migrate as far as the middle of South America each winter. All year long they specialize in catching bees and wasps on the wing, somehow avoiding being stung by their catches.”
