EASTERN ETHIOPIA 
XXVIII 
The most delicate use of beaks is nest building ; the 
neatness and beauty of many nests, especially those 
constructed by the weaver-birds are always a source of 
admiration. Some birds with apparently clumsy beaks 
build exquisite nests; other birds with dainty bills 
make ugly nests. 
The Open-bill {Anahtoinus lamelligerus). It uses its nut cracker¬ 
like bill to break the shells of molluscs. A feather from 
the breast is sketched to show the expanded terminal part 
of the shaft ; it is also slightly twisted on its axis. 
Some of the liirds which live in Eastern Ethiopia 
possess the largest and most curious beaks known to 
ornithologists. Such are the AVhale-hcaded Stork, 
Pelican, Saddle-billed Stork, Ilus, Marabou Stork, Open- 
bill, Goliath Heron, the Scissor-bill or Skimmer, and 
the Spoonbill.
