Yes, it should be safe as it is outside the cage and meant to warm up the whole room. I have bought the same model from Walmart but did not get to use it as my Senegal passed away on the day I brought the heater home. I have tried using heat lamp with a clamp at different positions near the cage and have also used infra red bulb thinking he could sleep better but the temperature inside the cage fluctuated quite a bit and not stable. The flat panel heater other has suggested was out of stock so we decided to purchase the oil infused heater. It's best if the bird cage is inside a small enclosed space/room to maintain a stable temperature. Make sure to use a thermometer to monitor the temperature inside the room. Recommend you to purchase an infra red handheld thermometer looks like a handgun aiming at the cage or even your birdie to check the temp inside the cage so you know the precise temp so you can adjust accordingly. My vet has instructed to maintain 90-95 F 24/7.
