206 NORTH AMERICAN BIRDS. 



nimbly among the young leaves, and thought they possessed many of the 

 habits of the Titndce. Their notes he described as few and weak, and in 

 their stomachs he found, upon dissection, small green caterpillars and a few 

 winged insects. 



Mr. Audubon also regarded it as a rare species, and only three specimens 

 ever fell within his observations. These were obtained in Louisiana and at 

 Key West. He describes them as appearing to be nimble, active birds, ex- 

 pert catchers of Hies, and fond of hanging to the extremities of branches, 

 uttering a single mellow tweet as they fly from branch to branch in search of 

 food, or while on the wing. 



Mr. N"uttall appears not to have met with it. Dr. Eichardson procured 

 only a single specimen at Cumberland House, in the latter part of May. 

 This was in a dense thicket of small trees, and was flying about among the 

 lower branches. He was unable to discover its nest, or to learn anything in 

 regard to its habits. 



A little more light has since then been given both as to its geograpliical 

 distribution and its mode of nesting. Specimens of this species have been 

 obtained in Costa Eica, Guatemala, Oaxaca, Mexico, and Panama. A speci- 

 men of this species was also taken in Colombia, S. A., by Mr. C. W. Wyatt. 

 Dr. Gundlach mentions it as occasionally found in Cuba. Mr. Drexler 

 secured specimens of it at Moose Factory and at Fort George in the arctic 

 regions. Specimens were taken by Mr. Bernard E. Eoss at Fort Simpson! 

 Mr. Eobert Kennicott met with it on the northern shores of Lake Winni- 

 peg, June 6. They were then abundant, and had already mated. He again 

 met with them at Fort Eesolution, and Mr. Clarke found them at Fort Eae, 

 Mr. W. F. Hall in ]\Iaine, ^Nlr. Bell on the Upper Missouri, and Professor 

 Baird in Pennsylvania. Mr. Eidgway has obtained it both in spring and in 

 fall in Southern Illinois, where it is abundant in some seasons. It does not 

 appear to occur on the Pacific coast. 



Mr. Boardman writes that the Tennessee Warbler is, in the summer time, 

 quite a common bird in St. Stephens and • vicinity. Its notes, he adds, re- 

 semble the low, subdued whistle of the common Summer Yellow-Bird. 



Mr. Maynard found this Warbler very common near Lake Umbagog dur- 

 ing the breeding-season. It was found in all the wooded localities in the 

 regions north of the neighboring mountains. Its song, he states, resembles 

 that of H. riificcqnlla, the notes of the first part being more divided, while 

 the latter part is shriller. 



A nest of this Warl)ler (Smith. Coll., 3476), obtained on the northern shore 

 of Lake Superior by Mr. George Barnston, is but little more than a nearly flat 

 bed of dry, matted stems of grass, and is less than an inch in thickness, with 

 a diameter of about three inches. It is not circular in shape, and its width 

 is not uniform. Its position must have been on some flat surface, probably 

 the ground. The eggs resemble those of all the family in having a white 

 ground, over wliich are profusely distributed numerous small dots and points
