tiny black critters

Today I pulled on the twig on which the hummingbird nest sits so as to better see the eggs, and I saw a broken eggshell. Then I noticed a tiny little black bird attempting to regain its balance. (Its sibling looked too recently hatched to have balance.) So I learned that knocking over little birds makes you feel like a jerk. Also, we didn't notice a bird nest on our front walk for about ten days.
