it is generally considered to be a wild and little visited region, it 

 has not been neglected ornithologically. 



The annotations treat of the mode of occurrence, region, migra- 

 tion, and distinguishing features of each of the species enumerated. 

 The annotations are well chosen, and add not a little to our knowl- 

 edge of the life history of the birds in that region. The paper 

 closes with a "Review," listing each of the resident 30, summer 

 resident 101, migrant 31, winter resident 13, and other species 4, 

 showing a total of 179 species which have been found in the 

 county. 



The Birds of Wisconsin. By L. Kumlien and N. HoUister. Bulle- 

 tin of the Wisconsin Natural History Society, Vol. 3, Nos. 1, 2, 

 and 3. January, April, July, 1903. 



The delay in the appearance of this catalogue of birds was oc- 

 casioned by the death of the senior author just before the comple- 

 tion of the manuscript, and later, by the absence of Mr. HoUister 

 in Alaska on business for the national Biological Survey. It is 

 a paper of 147 pages which makes no pretensions to being more 

 than an annoted catalogue of the birds of Wisconsin. Nor have 

 the authors claimed for it more than a conservative list of the 

 birds of their state. It contains no "light" records which have 

 not been relegated to the Hypothetical List, where they belong. 

 This safe conservativeness has reduced the number of species from 

 365 to 357, and thereby made their reputation for accuracy. The 

 feeling of security which this list gives the one who wishes to 

 know for a certainty what birds have been found in Wisconsin is 

 cause for congratulation. Few of the annotations are concerned 

 with more than records, but there are occasional glimpses of life 

 histories. The note in regard to the finding of a hybrid Helmin- 

 thophila pinus+H. rubricapilla adds another to the list of hybrids 

 which H. pinus seems capable of forming. It is to be regretted 

 that it was not possible to await the appearance of the young to 

 determine the form assumed by those hybrids in embryo. 



Eight full page half-tones from photographs by F. E. Burrows 

 from life add interest to the paper. We cannot but regret deeply 

 the untimely death of Mr. Kumlien, while we congratulate Mr. 

 HoUister upon the completion of the work under such trying cir- 

 cumstances.
