Last week Punxsutawney Phil predicted six more weeks of winter(*) but the birds know spring is on its way.
Northern cardinals (Cardinalis cardinalis) don't migrate so they're a good species to watch for early signs of spring. Some pairs stay together all winter on their home territory or in mixed flocks.
In February they begin to court. The males become aggressive toward other males and solicitous to their ladies. And they begin to sing. (Xeno-canto recording # 356015 by Ted Floyd)
Watch your local cardinals for these courtship behaviors:
- Lopsided pose : The cardinal tilts up one side of its body, raises one wing, lowers its crest and exposes its belly, sometimes rocking side to side.
- Song-dance display (shown by a female cardinal above): The bird stands erect, raises its crest and one wing.
- Song-flight display (quoted from Birds of North America): In flight the male fluffs his breast feathers, raises his crest, sings, and descends slowly toward his mate in short, rapid strokes. (Is the male doing this in the top photo?)
- Territorial Singing: (audio above)
- Counter-singing: Female cardinals counter-sing with their mates.
- Courtship feeding: The male cardinal presents food to his lady, beak to beak. Gene Wilburn in Port Credit, Ontario captured a male feeding his lady with a "kiss."
Cardinals are courting. Spring isn't far away.

NOTE(*): On Groundhog Day the Spring Equinox is six weeks away ... so it's always true that we'll have "six more weeks of winter."
