In the years since Chris Chester and his wife Rebecca rescued "B," a featherless baby bird - a creature with all the initial appeal of "a testicle with a beak" - they've had plenty of time to consider and reconsider their eccentric lifestyle. The upstairs floor of their home in Portland has become an indoor aviary. There is B's room, which he shares with a varying number of finches; the canary room; and the room housing the three subsequent foundling sparrows they've adopted: Baby, Pee Wee, and Seven. There are screen doors mounted in the doorways, congruent with "the Appalachian-themed decor." They've learned sparrow games like "War Bird," "Love Bird," and "Hit the Cap." The birds' bedtime rituals alone take an hour or more each night and cleaning the house for company means, essentially, cleaning room-sized cages. Not surprisingly the couple's social life has suffered a decline.
