Appendix 411 
The British form (M. raii) also occurs during spring, but rarely and on 
passage only, none remaining to nest. 
RESTRICTED DISTRIBUTION 
Rook (Corvus frugilegus).—There is a certain limited stretch—say a league 
or so, on the foreshores of the marisma—whither each winter come a few 
scores of rooks. At that one spot, and nowhere else within our knowledge, 
are rooks to be found in southern Spain. 
Macpie (Pica caudata)—On the western bank of Guadalquivir this bird 
abounds to a degree we have seen surpassed nowhere else on earth. But cross 
that river, and never another magpie will you see for a hundred miles to the 
eastward. For it the lower Betis marks a frontier. Over the rest of Spain 
its distribution is normal and regular. 
Asimilar remark would almost hold good of the Jackdaw (Corvus monedula). 
The AZURE-WINGED MAGPIE (Cyanopica cooki) abounds in central Spain and 
in the Sierra Moréna. But its southern range stops dead at the little village 
of Coria del Rio just below Sevilla. ’Tis but a few miles beyond, yet in 
Dofiana we have never seen so much as a straggler. The Azure-wing does 
not straggle. 
From Spain (as elsewhere stated) you must travel to China and Japan ere 
you see another azure-winged magpie. 
Jays (Garrulus glandarius) in Spain confine themselves to mountain-forests, 
eschewing the lowland woods which in other lands form their home.
