Hab. Eastern Norta America, from Hudson Bay southward, and west to the Great 
Plains, straggling thence to Nevada and Washington 9.—MExico, occasional in the 
State of Puebla, and at Jalapa and Orizaba in Vera Cruz (Sanchez *®). 
The Passenger-Pigeon, which formerly had a very wide range in North America, 
where it multiplied to such an extent that over a.thousand captures have been recorded 
in one year in the district of Michigan alone, has of late been so reduced in numbers 
that its breeding is now mainly restricted to parts of Canada and the northern portion 
of the United States, as far west as Manitoba and Dacota 9, where it nests in isolated 
pairs instead of in communities as formerly. We have reason to believe that 
E. migratorius wanders as far south as the tablelands near the city of Guatemala. 
The nest is a frail platform of sticks, and the eggs are usually two in number, both 
male and female birds taking a share in incubation. 
Fam, PERISTERIDA. 
The members of this family are mostly Ground-Pigeons. ‘They have the tarsus 
longer than the lateral toes, which are equal to, or only slightly longer than, the 
middle toe. 
According to Count Salvadori, seven subfamilies are included in the Peristeride, of 
which the Turtle-Doves (Turturine), the Bronze-wings (Phabine), and the Hackled 
Pigeons (Calcenadine) are Old-World forms, the rest being American. 
Subfam. ZENAIDINZ. 
The characters for the above-mentioned subfamilies are very slight, and the only 
features selected for the separation of the Zenaidine are the blackish, somewhat 
metallic, spot beneath the ear-coverts and the metallic gloss on the sides of the neck. 
Of the four genera comprised in the Zenaidine, one (Nesopelia) is confined to the 
Galapagos Archipelago; but the other three, Zenaidura, Zenaida, and Melopelia, are 
represented within our limits. |
