situation, and the egg's of Traill's Flycatcher as found in 

 Maine, are quite different from Mr. Henshaw's description 

 as given above. The nest is placed between vertical branches 

 of low bushes, at heights, above the ground, varying from 

 one to five feet ; it is Iposely built of grasses throughout. 

 This structure is smaller and less compact than that of Cv- 

 anospiza cyauea. says the same close observer. 



Having obeyed its natural instincts, this species returns to 

 our neighborhood, during the middle of September, on its 

 way to its more southern home. It now revisits its former 

 haunts, and preys upon divers coleoptera and lepidoptera. 

 A few berries of Jttnipcrus \ 'irginiana and Loniccra peri- 

 cIy!)2c)2H))i. which it discovers in these situations, are also 

 eaten. It still manifests all its former shyness, And flees 

 from the presence of man. During the last of September, 

 it takes its departure. 



The eggs of this species, says Dr. Brewer, have a white 

 ground with a distinctly roseate tint. They are oval in con- 

 tour, more slightly obtuse at one end than at the other, 

 and have well-defined blotches and spots of purplish-brown 

 about the larger extremity. Their measurement is .63 by 

 .^6 of an inch. Mr. Henshaw says the eggs of this species, 

 are often discovered with a decided cream color approxi- 

 mating buff; which differ from those of acadicus in being 

 less buflV ; but admits that specimens of the latter are occa- 

 sionally found, quite as pale as some of the former. Dr. 

 Wheaton remarks that while he is unable to note any spe- 

 cific difference in the eggs of the two species, he thinks that 

 the eggs of acadicus are, on an average, somewhat longer 

 and slenderer than those of TrdiUii^ and possess a yel- 

 lower buff tinge. Mr. Purdie describes the eggs from 

 Maine as having a pale creamv white ground-color, and 

 marked with two shades of reddish-brown, dots, spots, or 

 blotches, which are chiefly disposed about the larger ex- 

 tremity.
