(Noun.) A constantly chirping(hence why they are birds,) smoke detector which is usually mounted on the ceiling, perhaps unbeknownst to its
owner that it is indeed in need of a new battery.
These entities appear to be found vastly disproportionately in the dwelling places of those of
African descent, for reasons researchers are still trying to discover. Possible theories include:
a.) The people in question are simply too lazy to do the few minutes of work to get a step ladder and to change
the battery.
b.)They are not forward-thinking enough to keep extra 9v batteries in storage, therefore a trip to the store is required. The ceiling bird keeper is subsequently either too lazy to go the store, or too cheap to want to pay for a new battery.
c.) The chirping/beeping is simply drowned out by the cacophony of other sounds - loud/poorly behaved children, loud music, TV, constant yelling, etc. Thus the owner is unaware of the problem in the
first place or has learned to just tune out the chirping.
