Sorry to hear about the nest, bummer for sure. Just thought I would mention just saw a cardinal land in my yard all red, perched on a sheperds hook for a few seconds then off he went. I mention this since I could easily count on one hand the amount of times I will see one in a season.
OOPS- Dan just saw something landed on my yardlight. It looked for all the world like a male cardinal with the mohawk crown except for one thing , it was a light brown.
