General Notes. 1 89 



The notes frnni whicli these tables are prepared were obtained bj walk- 

 ing continuously over the routes named, without retracing steps in any 

 case. When a bird was observed a record was made in the form of a 

 dot placed against the name of the bird. The dots were placed for con- 

 \enience in groups of five each separated bv straight lines. 



It seems a little remarkable that the four averages of the two localities 

 should so nearly coincide. The fact that thej do coincide so closely sug- 

 gests that, unless we have here an unusual recurrence of figures, the 

 averages represent a tolerably definite factor of the bird population of the 

 two localities at the time the observations were made. The statistics do 

 not indicate the actual bird-population in the two localities ; but they do 

 show, it seems to me, the relative abundance in the two sections, and, to 

 a large extent, the relative abundance of the various species in each 

 locality. 



It is to be observed that the notes from the vicinity of Ithaca were taken 

 in June before many of the young birds were upon the wing, while those 

 from the other locality were made after the breeding season. The two 

 localities should not be compared, therefore, without taking this fact into 

 account. For instance, all the Bobolinks observed on trip 8 were, with 

 two exceptions, males. Hence the figures probably show only about one- 

 half the number of birds of this species that existed in the territory at 

 the time of the visit. 



In July, 1878, about the middle of the month, I went over route 5 and 

 6 a second time to see what effect upon the average the addition of the 

 young birds would have. The whole number of birds observed was a 

 little more than double that observed in June. 



Perhaps some one will suggest a better method of obtaining the facts 

 recorded in this connection. — F. H. King. River Falls, Wis., May 24.

Remarks on Five Maine Birds. — It appears that no formal announce- 

 ment of the occurrence of the Gray-cheeked Thrush {Hylocichla alicice) 

 in the State of Maine has ever been made, though the course the bird is 

 known to pursue in its migrations renders such an announcement of slight 

 importance. It may be stated, however, for the benefit of compilers, that 

 this Thrush is a regular, not very common, spring and fall migrant in 

 southern Maine, reaching Portland in spring about the middle of May, 

 and in autumn about September 20. 



A propos of Dr. Coues' recent prediction* that the Titlark {Anthus 

 ludoviciatius) will yet be ascertained to breed occasionally along the Maine 

 coast, is there anything but inferential evidence to indicate that it occurs 

 there at all in spring or summer.? Being known to pass through Massa- 

 chusetts in spring and to occur on the island of Grand Mananf at that
