おもしろい事実

Despite their bright color, males are not fully blue until they are about a year old.

Male Blue Grosbeaks get their brilliant blue color from feather structures, not blue pigment!

Some Blue Grosbeaks line their nests with shed snakeskins, possibly to scare away predators.

These birds often migrate at night, covering long distances under the cover of darkness.
