I'd never seen baby cardinals before. There were three in a nest across from the Herb garden at Boyce Thompson Arboretum on a hot summer day, August 18, 2007. There was an adult male and female cardinal in the area and the babies would get excited whenever one of these birds came near. I got proof when the female cardinal cautiously came up and fed the three babies. I got some pictures, not real good, but it was quite exciting.
