What a difference a couple of weeks makes! What a transformation! Two weeks ago, the eyasses were tiny and weak. Their vision was poor, they responded to Bell's "chirps" by opening their beaks so she could put food there, and they had no apparent awareness of anything beyond her warmth, their own fuzzy huddle during the few minutes they were left uncovered, and the food Bell put in their mouths.
Today, after uncountable meals stuffed into them by their mother, they are alert, they are eager for food (on the rare occasions that they are left without food for long enough to get hungry), and their fuzzy heads turn and dark eyes follow the world beyond the ledge. They preen, attempt to flap their wings, and shuffle around awkwardly in the nest box. We expect their first explorations of the ledge within a few days.
A few "real" feathers are beginning to peek out from under the coats of white fluff, and we can see a hint of the peregrine facial pattern they'll wear as fully feathered birds. Watch them change from day to day.
