The Migration of North American Sparrows

mountains it t)rfc(ls soutli to northern (icur^ia. It is the hitler fact which 

 exi)hiins the mif];ration (hitcs in Xorth Carohna. The species arrives near 

 Asheville in the mountains, where it breeds, nine clays earlier than at Raleigh 

 in the lower land, where it does not breed. Other birds, that breed at both 

 places, always arrive earlier at Raleigh. 



The Rose-breasted Grosbeak is also a good example of what is almost a 

 general rule, that birds migrate earlier in the Mississippi Valley than at corre- 

 sponding latitudes on the Atlantic slope; it arrives at Beaver, Pa., four days 

 earlier than at Washington, I). C, more than a hundred miles further south. 



Another striking peculiarity in the migration of this bird is that there are 

 no dates of arrival on the Gulf coast of Louisiana and Mississippi to corresj)ond 

 in earliness with those of Missouri and Illinois. The facts seem to be that the 

 early migrants — fully adult and strong-winged birds — fly across the Gulf of 

 Mexico and far inland, over Louisiana and Mississippi, before they alight; 

 and it is only the later, younger, and weaker birds, or occasionally stronger 

 birds buffeted by a tempest, that are noted near the coast.
