Cardinal songs

The trees are still bare, so when I hear one of the cardinals singing, I can often spot it at the highest point. In this video, you get to hear four different calls: the "water sprinkler" song, the "squeaky toy" song, the "pew! pew! pew! pew!" song, and the "bu bu bu chip chip chip chip chip chip chip chip" song.
In this next clip, you can see both the male and the female as they sing together.
