LOCUST BIRDS 



11 



Beyond the clump selected by the birds as a nesting site 

 there were no isolated nests, although the trees extended all 

 round. All the nests examined — about twenty — ^had two 



apertures, both on the same side. On January 20, 1906, 

 the birds suddenly departed, leaving a few half-fledged 

 young, and some eggs to perish and decay.
