According to the above data, the catbirds made the best record in 

 average young bird production per nest of all those species, building five or 

 more nests, two young per nest. Likewise the mourning doves did the poor- 

 est, averaging about one successful young to each five nests. 



Some of the eggs were crushed, some were apparently eaten by birds, 

 and many were thrown out of the nest by storms. The towhee nest, men- 

 tioned above, was, according to report, destroyed by a boy who was making 

 a collection of bird's eggs. One robin nest was destroyed by a cat.
