Alcedinid^:. 



71. Ceryle alcyon Boie. Common. 



CuCULIDjE. 



72. Coccygus americanus Bon. Frequent. 



73. Coccygus erythrophthalmus Bon. Frequent. 



Picid^e. 



74. Picks pubescens Linn. Common. 



75. Picas villosus Linn. Common. 



76. Sphyrapicus varins Bel. Common. 



77. Mdanerpes erytlirocephalus Sw. Very abundant ; more numerous than all the other 

 Piciclce together. 



78. Centurus carolinus Bon. Quite common. 



79. Colaptes aurcdus Swain. Abundant. It is a well-known fact that when the eggs of 

 this species are successively removed from the nest while the female is laying, that she will 

 continue laying till she has much exceeded her usual number. Mr. F. J. Huse related to 

 me a case within bis knowledge, where twenty eggs were taken from the same nest, before the 

 female was shot. As might have been expected, she was found to be exceedingly poor in 

 flesh. Had she not at this point been killed, it is impossible to say how many more she 

 would have laid, though undoubtedly several. 



From the above list we see that the Picidce are very differently represented here from 

 what they are in the Eastern States, through the almost entire absence there of Mdanerpes 

 erytlirocephalus and Centurus carolinus, which here, and especially the former, are predominant 

 species. Picus pubescens and P. villosus appear on the other hand to be rather less numerous. 



In Kalamazoo and Van Buren counties, Mich., the third week in October, I found C. 

 carolinus the most numerous woodpecker, M. erytlirocephalus having in part no doubt gone 

 south. In the dense forests Hylatomus pilcatus was not rare. At this season C. carolinus was 

 very restless and active, running hastily over the trunks and branches of the trees, spending 

 but a minute on one before flying to another, and then to a third, often in a few seconds 

 returning again to the first. Its principal food seemed to be beech-nuts, in gathering which 

 it clung to the twigs like a titmouse, and was rarely seen digging into the decayed parts 

 of the trees for larvce, as its associates, the Hairy and Downy Woodpeckers, were doing.
