How do I set temperature, humidity, and lighting for my African Grey cage?
Keep the warm side at 78°F (25.5°C) and the cool side at 70°F (21°C) while maintaining 45‑55% humidity and 10‑12 hours of full‑spectrum light each day. These numbers give your African Grey a stable environment for decades of intelligent play.
Target ranges for temperature, humidity, and light
Aim for a warm perch zone of 78°F (25.5°C) and a cooler perch zone of 70°F (21°C). A digital thermostat set to 74°F (23°C) will keep the average inside the cage within the 70‑80°F band. Humidity should sit between 45% and 55% measured at head height; a hygrometer calibrated to ±2% works best.
Provide 10‑12 hours of full‑spectrum daylight, roughly 5,000‑7,000 lux at perch level, using a 40‑watt LED fixture placed 12‑18 inches above the cage. Nighttime darkness should be uninterrupted for at least 8 hours to support melatonin cycles. If you live north of 40° latitude, a programmable timer will keep the photoperiod consistent year‑round.
- Warm side: 78°F (25.5°C)
- Cool side: 70°F (21°C)
- Humidity: 45‑55%
- Light: 5,000‑7,000 lux
- Photoperiod: 10‑12 hrs
Why a temperature and humidity gradient matters
African Greys thermoregulate by moving between warm and cool perches, so a single temperature creates stress and can suppress natural foraging behavior. The gradient lets the bird choose a spot that matches its metabolic state after a nap, a meal, or a vocal bout. When humidity fluctuates too far, the bird’s respiratory membranes dry out or become soggy, leading to plume damage.
In practice you’ll see the bird perch on the heated side after a long flight, then retreat to the cooler side during a quiet afternoon. This movement also distributes waste, keeping one side cleaner and reducing ammonia buildup. A well‑balanced gradient therefore supports both physical health and mental stimulation.
Controlling temperature, humidity, and lighting
Install a low‑wattage ceramic heat emitter (10‑15W) behind a metal screen on the warm side, and plug it into a thermostat that cycles at 74°F (23°C). Position the emitter 6‑8 inches from the cage wall to avoid hot spots; use an infrared thermometer to verify the perch temperature. For cooling, place a small oscillating fan (30CFM) on the opposite wall, set on low, to circulate air without creating drafts.
To hit 45‑55% humidity, line the cage floor with 2‑3 inches of coconut husk substrate and mist it with 1‑2cups of water twice daily. A 0.5‑gallon ultrasonic humidifier set to 50% can supplement misting during dry winter months. Place the hygrometer on a perch at head height, not on the cage floor, and recalibrate it every 30days.
- Ceramic heat emitter: 10‑15W
- Oscillating fan: 30CFM
- Substrate depth: 2‑3in
- Misting volume: 1‑2cups
- Humidifier capacity: 0.5gal
Observable signs that conditions are off
If the bird’s feathers look ruffled, eyes are watery, or it pantes with its beak open, temperature is likely above 82°F (27.8°C) or humidity below 40%. Check the perch with a handheld thermometer; a drop of 3‑5°F from the target is enough to trigger stress. Over‑heating also shows up as reduced vocalizations and a tendency to stay on the cool side all day.
Conversely, fluffed plumage, frequent sneezing, or a sticky droppings pattern point to humidity above 65% or temperature below 68°F (20°C). Low light will cause a dull feather sheen and a loss of interest in toys; measure lux with a handheld meter—values under 4,000 lux indicate insufficient lighting. Adjust the thermostat, humidifier, or lamp distance accordingly.
- Over‑heat signs: panting, watery eyes
- Cold signs: fluffed feathers, lethargy
- Low light: <4,000 lux, dull plumage

Related questions
Can I use a regular space heater for the warm side?
A space heater above 150W creates uneven heat and can exceed 85°F (29.5°C). Use a 10‑15W ceramic emitter with a thermostat instead; it stays within the 70‑80°F range.
How often should I calibrate my hygrometer?
Calibrate every 30days using a saturated salt solution; this keeps readings accurate to ±2% humidity.
What lux level is safe for night lighting?
Keep night‑time illumination below 100 lux—just a dim red LED night‑light placed 24 inches away prevents disruption of melatonin.
