I was curious to learn more about robins, how long until the eggs hatch, how long before the babies will be old enough to fly away, and found this photo essay: http://www.i-pets.com/rpet19.html There is a lot of information there, as well, about what robins do re cleaning up after themselves and what they feed on.
Saves me from disturbing her to take a pile of pictures that probably wouldn't show very much. If nothing else, I'd have to put a step stool outside to get up high enough to see into the nest.
She's sitting there gazing out over the yard. I wonder what birds think about.
