The British form {j\[. raii) also occurs during spring, 1)ut rarely and on 

 passage only, none remaining to nest. 



Kestricted Distribution 



Rook (Corms fnu/iktjns). — 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. 



Magpie (Pica caudata). — On the westei-n hank of Gnadalcjuivir this bird 

 abounds to a degree we have seen surpassed nowhere else on earth. I5ut cross 

 that river, and never another magpie will you see for a hundred miles to the 

 eastward. For it the lower Bjetis marks a frontier. Over the rest of Spain 

 its distribution is normal and regular. 



A similar remark would almost hold good of the Jackdaw {Corvus monedula). 



The Azure-winged Magpie {Cyanopica roold) abounds in central Spain and 

 in the Sierra Morena. 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 

 Doiiana 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 (Gamihs (jlandarius) in Spain confine themselves to mountain-forests, 

 e.schewing the lowland woods which in other lands form their home.
