52 The Nuthatch. 
> 
This bird nests in the month of April or May, laying 
from four to six eggs in a nest composed of grass, 
leaves, and other rough materials, and is mostly found 
in a crack of a tree. If the opening is too large’ to 
please its fancy, it gets some clay and plasters it 
round, so as to leave only just sufficient room to get 
in and out.
