On this morning’s walk through south Oak Park, I heard male Cardinals singing in four different back yards. That’s the first time I’ve heard Cardinal songs this year!
In case you’re not familiar with its song, this link should take you to an All About Birds multimedia page: Songs and calls of the Northern Cardinal.
(To hear the songs, you need Quicktime installed on your computer.)
Nature Note added 1:15 p.m. on Monday, February 2:
I heard more Cardinals singing this morning! One was in our neighbor’s yard at 6:30 a.m. The other was at Columbus Park, near Austin, at 11:30 a.m.
It will be interesting to see how many Cardinals visit our feeders now that males are singing. During January we often had 6 or 7 Cardinals in our yard near sunset (our highest total was 9). Are singing Cardinals setting up territories to defend? If so, will the local male allow other Cardinals to enter his territory and visit our feeders?
