Cardinals outside my window

Sunday morning my hubby yells "I just saw a flash of red flying in front of the window". I looked outside and there was a cardinal family on the ground looking for food in our backyard. I grabbed my camera and was able to get a couple of snaps before they moved on. They did not stay very long. The first picture is of a baby just learning to fly. It looked pretty scrawny and it's beak is still a dark color. Based on the dark red coming out on the head and the sides it may be a male. The second is the mom. She's got the orange/red beak and red tail. The last is of the dad with a snack in his beak. Some sort of bug. Again, why does the male bird always look prettier than the female bird???
