The bright red male cardinals are easy to spot this time of year; there was a fellow up in one of the oaks behind the Discovery Center singing loudly yesterday. One of the wonderful side benefits of learning common calls and songs is having their songs draw your attention. The 'What, cheer, cheer, cheer' call of this cardinal was unmistakable!
It's just like recognizing voices of your friends.
Have you heard these songs lately?
