Delichon urbicum
Swift or Swallows found in the Algarve, Portugal. Unfortunatley one had died, but may help in identifying the species.
Thought it may be House Martin!
Please consider putting these lovely nests in the Animal Architecture mission at http://www.projectnoah.org/missions/8082...
I've just started reading a book called Avian Architecture by Goodfellow. It's about how birds build their nests and it's full of pictures and diagrams. I think I'll skip straight to the chapter on mud nests after seeing these pictures!
