The number, and why it matters more for a grey
An African grey parrot needs roughly ten to twelve hours of sleep in each twenty-four hours, and it needs most of that as one unbroken block at night. Greys come from equatorial regions where day and night stay close to equal all year, so their body clocks are built around a long, regular dark period rather than the shifting seasons of temperate latitudes. What sets the African grey apart is sensitivity. This is an observant, easily unsettled species, and sleep debt in a grey rarely looks like tiredness; it looks like behaviour. A grey that is short on sleep is more likely to be nippy without warning, to call repetitively, to startle at familiar things and to turn its attention to its own feathers. Before treating any of those as training problems in a grey, an honest audit of the previous fortnight's nights is the right first move.
What counts as sleep for a parrot
Hours with a cover on the cage are not automatically hours slept. A grey dozes lightly through evening conversation, television light leaking under a cover and household members passing the cage, and that fragmented dozing does not do the work of deep night sleep. Real sleep needs darkness the bird cannot see light through, quiet that is more than a turned-down volume, and freedom from disturbance such as late cage cleaning or a dog settling beside the cage. The most reliable arrangement for a grey in a busy home is a sleep cage: a smaller, simply furnished cage with a sleep perch, water and a cover, kept in the quietest room in the house and used only for the night.
Building the night routine
Work backwards from the wake time your household can keep every day, weekends included, and set lights-out ten to twelve hours before it. Build a short wind-down in front of lights-out: lights lowered, interaction calm and quiet, a last drink and a small evening feed, then the move to the sleep cage or the cover going on without prolonged goodnight conversation.
Signs the night is not working
Read the mornings for evidence. A well-rested grey wakes bright, vocalises moderately, eats with interest and engages with toys and people. Persistent signs that the sleep block is failing include a bird that is fluffed and silent on the perch well into the morning, one that is unusually reactive or bitey at handling it normally accepts, a rise in feather chewing or plucking, and night disturbance itself: repeated startling, falling from the perch or calling out in the dark, which can reflect a sleep space that is not dark or secure enough. Adjust one thing at a time, such as moving the sleep cage to a quieter room or bringing lights-out earlier, and give each change a week before judging it. If restlessness, plucking or appetite changes continue despite a genuinely protected night, discuss the bird with an avian veterinarian, since pain, illness and hormonal changes can all disrupt sleep and mimic simple tiredness.
Holding the line in a household that stays up
The practical enemy of a grey's sleep is a home that is awake and lit until late, with the bird in the middle of it. The sleep cage solves most of this, provided the transfer happens at the bird's bedtime and not the household's. Agree the bedtime as a fixed household appointment, protect the sleep room from late visits, deliveries of laundry and charging lights, and keep the routine identical when guests stay or routines change on holiday weeks at home. A grey given its full, dark, predictable night is calmer, healthier and far better company through the day. Assigning cover-down, transfer and morning uncover to named people each day with KinsLe Care Teams makes sure the grey's bedtime survives busy evenings when everyone assumes someone else has done it.
