It was my hope to follow the development of our nesting Cardinal to the fledge of her brood. Last evening I noticed that she was off the nest. At 1st I thought that she was taking a break to feed . I checked the nest from the window several times but she did not appear. This morning I went into the back yard and found the nest empty. Momma and eggs were gone !! I assume that a snake or other critter took the eggs.
