BLACK-HEADED JAY. 147 
name of the Russian naturalists, Zdicet?, considering that 
Gené’s species is different, and not found in Europe. 
Whether this is correct or not there seems to be no 
doubt but that the habits of the Common Jay and the 
species we are now considering are precisely the same. 
For the same reason then that I introduced some 
interesting details by Professor Moquin-Tandon, on the 
nidification of the Common Magpie, I quote here some 
equally valuable notes from his paper on the Nests and 
Eggs of the Common Jay, (Garrulus glandarius.) 
They are extracted from the “Revue de Zoologie” for 
March, 1858:— 
“Tt is well known that the Jay builds in oaks, ches- 
nuts, birches, and beeches, at a height of from five to 
eight metres, (sixteen to twenty-four feet;) it rarely 
chooses bushes. Its nest is in the form of a shallow 
cup, more or less extended. I have seen a large number 
of them, and they are all very much alike. Four of 
them averaged about three inches high, six inches in 
diameter, and two in depth. 
In the materials which compose their nests are found 
on the outside small branches and twigs of oak, chesnut, 
and beech, and inside slender roots of heath and stalks 
of grasses. 
The eggs of the Jay are in number from four to 
seven. and of a dark grey, with a more or less bluish, 
greenish, or reddish shade, with small olive-coloured 
spots in great number very close together. 
These eggs vary very much in colour. In 1838 one 
hundred and three were brought to me from the Black 
mountain near Revel, some fresh, the others hatched. 
I noticed in this number fifty-six of a greenish grey, 
finely and indistinctly spotted with olive green, (this is 
the type;) twenty-one less grey, rather bluish, with
