11 nian y parts of Southern Europe the Jackdaw is local, but it 
°': CUrs in the countries north of the Mediterranean and in 
Algeria. It has not been found in Egypt, and in South- 
eastern Europe is replaced by Colceus col la ris, which takes its 
piace to the eastward. 
Habits. — The Jackdaw is decidedly a gregarious bird like the 
°ok, with which it is a close companion, especially in winter, 
jangrating in flocks along with that species. Even in the 
eeding season many pairs nest in company, and we have 
n own as many as ten nests in a single old tree. Cathedral 
wE U n * v ’ersity towns are favourite haunts of the Jackdaw, 
\ 1lc h finds its favourite nesting-places in the old towers and 
^lurches. In many places, however, the bird builds in holes 
cliffs and in rabbit-burrows, and not unfrequently in the 
pen. We have ourselves seen a Jackdaw’s nest on the ledge 
a w i n dow-sill of an outhouse. 
., Ne,t — The nest is an untidy structure, by no means equal to 
at of the Rook as a piece of architecture, and is composed of 
cks, moss and grass, with a few feathers occasionally added. 
E £gB.-— From three to six in number, bluish green or bluish 
^ nte, with obscure grey spots and bolder spots and markings 
brown or greenish brown, distributed pretty equally over 
le ’"’hole egg. Axis, 1-35-1 '55 inch ; diam., 0-9-1-! inch. 
o j. in dry seasons, when food is difficult to obtain, the number 
, e ggs is often only three, and many young birds perish in 
iae nest.
