Sunday Bird Market

After visiting Sainte Chapelle on the Île de la Cité the last Sunday of our stay in Paris, Bill and I visited the bird market on the island. Bill caught this portrait of one of the sellers.
The birds certainly were beautiful in their tiny cages.
Hard to imagine them not going a bit stir-crazy, though, having only each other to talk to.
These fluffy, feathered friends reminded Bill of Big Bird. What ARE they?
