That old sweet song

I had been hearing a cardinal in the area where the trail comes out on the rail bed off and on over the last week or so, but today was the first time I got a glimpse of it. I must have chased it from one tree to another for ten minutes before I could get a decent shot. It's easy to identify this gorgeous bird from its distinctive loud, clear whoit-whoit-whoit song. Not really a bird associated with a marsh habitat, but certainly with the adjacent 'open-edges' areas. This male has probably already established his territory.
