a bird in the bathroom vanity

sometimes we get rather unusual calls at oak knoll. since we are a mass audubon facility, we are assumed to be experts in all matters related to birds. for example, this past saturday, a woman named tricia called because she had a bird trapped in the bathroom vanity (she could hear in fluttering around in there) in her apartment and wanted me to come get it out. she had me talk to amanda, who was an employee of the apartment management company, and i told her, "look, i am going to come over there with a paper bag, shoo the bird into the bag, walk outside and let it go. don't you think you could just do that yourself?" but both amanda and tricia claimed to be "too freaked out" by the idea of this bird in the vanity to attempt any sort of rescue/extraction procedure on their own.

so i drove the 20 miles out to franklin to assess this bird situation for myself. i eqiupped myself as best as possible for this sort of work with a pair of fleece gloves and a cat carrier. i shut myself in the bathroom, cracked open the vanity door and discovered....

a parakeet (very similar in appearance to the blue one in this photo).

tricia told me her neighbors owned birds, so we brought the poor parakeet down the hall to the next apartment to see if this bird was one of theirs. i was relieved to learn that the bird did belong to the people next door, because finding a parakeet had destroyed my plan to extract the bird from the vanity and walk outside and release it. the neighbor said, "oh, he got out of his cage yesterday when we were cleaning it and he flew into the kitchen cabinets and we thought he was gone for good." although i was not familiar with the idea of kitchen cabinets being a no-man's-land for parakeets, i nodded knowingly, accepted her abundant thanks, and left.

out in the hall, tricia told me, "the last people who lived there had hampsters that they kept in the kitchen cabinets and one time they chewed a hole in the back wall and got into my bathroom vanity."

this means that before i arrived at tricia's apartment, she possessed the following three pieces of information:
1. her neighbor owned birds
2. there was a direct link between her neighbor's apartment and her bathroom vanity
3. there was a bird in her bathroom vanity.
if this was an SAT logic puzzle, i'd guess that 99% of students would have been able to answer it correctly.

and who keeps hampsters in their kitchen cabinets?
