Fix It: Surprisingly, it's not the sound or lack thereof that's keeping you awake, "it's the inconsistency of sound or silence that's disruptive," says Thomas Roth, PhD, director of the Sleep Disorders and Research Center at Henry Ford Hospital in Detroit. Turn on a nearby ceiling or exhaust fan. "This will act as white noise, both blocking out disruptive sounds and providing just enough noise for those who can't stand total silence," Roth says. A white-noise machine will do the trick, too—the devices help patients sleep in the busy, active intensive care units of hospitals, according to a report in Critical Care Nursing Clinics of North America .
Feathers are complex structures that require constant care called preening. Preening removes dirt, spreads the bird’s body oils and realigns the feather’s structure. It is also a social activity between birds and their mates and owners. Most parrots have an oil or preen gland (uropygial gland) situated at the base of their tail which is the source of most of their feather oil. Without this oil, the feathers will absorb rainwater and the bird will be unable to fly or maintain its normal body temperature.
