My observations: About the size of a robin but with more rounded bodies, Western bluebirds add flashes of glorious blue to your garden. As you can see, the males have intense blue plumage with reddish breasts. The females have paler blue wings and light reddish-brown breasts. They are quite congenial although will quickly defend their nests and territories against other birds. They have voracious appetites for insects. Bluebirds migrate south for the winter.
