Clay Handmade Bird Incense Burner

Hand made in clay, part has a gloss glaze over it. Two holes on each end, one larger than the other. I believe you put a bit of burning incense inside and light it. The smoke will come out the bird's beak. I don't see a signature but I do see what looks like a small heart on the bottom. The teapot lid is attached. Good used vintage condition. 5.5" x 4.5" x 3.75 H *As far as I know it's an incense burner but I have no idea honestly. It doesn't' smell at all, could just be a decorative piece or used as one. If you have any idea what it is please let me know!
