JACKDAW.

Mr. Wolley, referring to the point in dispute, whether 
or not birds of the crow kind cover their eggs, says, in 
the “ Zoologist/' “ I have a fact to offer on this disputed 
point. About ten days ago, Henry Walter and myself 
amused ourselves by climbing up to Jackdaws' nests 
placed in holes in the trees about Bearwood, which is on 
the borders of Windsor Forest. In the course of three 
days we must have examined several score of nests. On 
the first day none of the eggs were covered, but on the 
second and third days, we found that several of the nests, 
that had been visited before, now had their eggs either 
partially covered by loose pieces of wool, or the eggs, in 
some cases, were nearly buried in the woolly lining of 
the nest, and this, whether the bird had just flown from 
the nest or not."
