At the top of our front porch pillar is a colorful nest where five baby phoebes peer down at me silently as I pass. They stack together like spices in a pantry, and with their insatiable appetites, both parents work in tandem to provide a steady stream of food.

Early in the morning, I hear the male phoebe's song from across the yard. Perched on a bare yucca stem, he scans the ground for a fat bug to feed his nestlings. He swoops down, flying low like a crop duster, and pivots to catch his plump prey. After admiring his kill for a moment, he flies up to deliver a meal to the hungry chicks. Following him, the female wrestles with a butterfly to provide dinner for the voracious nestlings. Not all of their prey submit willingly. 

By this afternoon, three of the nestlings had climbed out of the nest and onto the pillar ledge, creating some breathing room in their stifling quarters. They won't be here much longer. At least then, the butterflies will be able to breathe a little easier.
