Bird Figurines Warbler 1938 - Blue Jay 1938

I have 2 ceramic bird figurines one is a blue jay - the other is a warbler. Both are marked warbler 1938 - blue jay 1938. The year 1938 is under the name of each bird. Any help identifying the maker would be extremely useful to me. The 2 birds just broke and I need to replace them. Thank you.
