These three birds are recent estate purchase. The smallest bird I believe is made by Titan glass. It measures approximately 4x2.5 in. The other two birds I believe are made by Viking Glass. The green bird is 13 in and the Amber Bird is 10 in. The Amber bird has a very tiny chip on the underside of the base. I've circled it in a couple pictures so you can judge for yourself. Virtually unnoticeable when displayed. Feel free to ask any specific questions.
