Budgies, also commonly known as budgerigars or parakeets, are birds that can make wonderful family pets. These birds are intelligent and can even enjoy being handled if trained properly. Budgies don't require a lot for their care, but they should be kept in a cage that will stay warm to prevent them from getting health problems. There are measures you can take to keep a budgie's cage warm enough for the bird to remain happy and healthy.
Move your budgie's cage to a room without a draft. An ideal area would not be near open windows or doors.
Use a towel, sheet, or blanket to drape over your budgie's cage. This is especially important at night, but you may need to cover the cage during the day as well if it gets too cold.
Attach a heated perch or panel to the budgie's cage. A heated perch will give your bird a warm spot inside the cage, even if it gets a little chilly in your home. Heated panels, which are attached to the back or bottom of the cage, can warm up large areas of the cage quickly and effectively
Keep a budgie's cage out of direct sunlight, as well as away from drafts.
Watch your bird for signs of overheating. If you notice your budgie lifting its wings up and away from its body, fluffing its feathers, or stretching its neck out, remove the source of heat immediately. Check with your vet if these symptoms persist.
