180 Norton, Evening Grosbeak in Maine. [April 



It is unfortunate that the last two records are without specific 

 dates, which would enable us to determine whether they belong 

 to one or to two seasons. 



The season of 1878-79 * found the birds in Kalamazoo County, 

 Michigan, from Nov. 20 to May 6, and as far south as Lafayette, 

 Indiana, 2 where one was taken, and as far west as Minnesota. 3 



In 1883-84 a migration of noteworthy proportions occurred, in 

 Minnesota, Wisconsin and Iowa, 4 with records from Indiana, 5 and 

 New York — the date of the last being July 8, 1882. 6 



In 1886-87 another extensive migration was observed, when the 

 birds were more or less abundant, — sometimes in considerable 

 numbers, from Wisconsin and Iowa, to New York, and from 

 Ontario to Kentucky. The next migration 1889-90 carried the 

 bird into Minnesota, Montreal and Maine, and southward to 

 Pennsylvania. Since that time its occurrence in parts of the region 

 east of Lake Michigan has been frequent and migrations of larger 

 proportions have occurred in the easternmost states in 1910-11, 

 1915-16 and 1916-17. 



With due consideration of the fact that we are dealing with a 

 member of the Coccothraustinae, a group in which many of the 

 species are noted for the irregularity of their migrations we have 

 found in the review just taken that the bird under consideration 

 has been constantly extending its winter range eastward since 1854. 

 It should also be remembered that the blank period in the bird's 

 history between 1823 and 1853, as well as that in the early eighties, 

 when its records begin to multiply, are periods when there were but 

 few observers, and perhaps even fewer mediums of publication, 

 to say nothing of the undeveloped habit of publishing personal 

 observations. And we find to day, much force in Butler's state- 

 ment, — " had there been the number of observers at those times 

 there are now, we should have learned more of the extent of those 

 dispersals."
