OUR PRESENT KNOWLEDGE OF THE NIDIFICATION OF 
THE AMERICAN KINGLETS.^ 
BY ERNEST INGERSOLL. 
In the hope of eliciting from some Of the many readers of The 
Bulletin farther information concerning the breeding habits of the 
American Kinglets, or at least of putting them upon the alert for 
further information, I have deemed it well to bring together what 
is at present known respecting the nidification of these birds. 
Of the breeding of the Ruby-crowned Kinglet {Regulus calendula, 
Licht.) not much is known, although the bird is found, at different 
seasons, in all parts of North America. In the Rocky Mountains 
it breeds among the most elevated forests. Mr. J. A. Allen found 
young in July near Mount Lincoln, Col. ; Mr. Ridgway gives it as 
breeding among the peaks of Northern Utah; and Mr. Henshaw in 
Arizona. It is also supposed to breed in Northern New Jersey, in 
Western New York, in Maine, and in the islands of the Bay of 
Fundy. In Western New York a nest which contained young was 
reported to have been built in the fork of a tree. Males and 
females have both been observed in summer about Chestnut Hill, 
Philadelphia, and Mr. Gentry thinks it Bests on the wooded heights 
along the Wissahickon. Dr. Coues, in his “ Birds of the North- 
west,” considers that he has Sufficient evidence to show a breeding- 
range throughout the mountains of the West, from nine thousand 
feet upward, thence trending eastward along the northern boundary 
of the United States to Maine and Labrador, and probably sending 
a spur southward along the Alleghany Mountains. Northwestward 
it reaches Alaska*
