I am blessed to have a pair of Northern Cardinals in my backyard woods and coming to my bird feeder occasionally. At the breakfast time this morning, I was attracted by the male cardinal song call. Sure enough, he was on top of a tree branch and making the calls for at least fifteen minutes and I could hear the female response call from distance but never did show up. The cardinal song call is like the whistled music and it was so beautiful to listen the song calls back and forth. What a way to start my day!
