Sparrows, Swallows, Yellow Palm and other Warblers, and the 

 Thrushes. At the end of the book there is a hypothetical list of 

 birds which may almost certainly be expected to occur in the State, 

 but which have as yet not been positively detected. Among these 

 is the Bicknell's Thrush, which is almost beyond doul^t a breeding 

 species in Maine, but no specimen has yet been actually taken. In 

 his summary Mr, Knight says, "The number of species given in the 

 list as positively occurring, or as having occurred of their own free 

 will within our limits, or being introduced to have persisted until the 

 present time, is 327. Of these some 26 are permanent residents, 

 including 2 introduced species. The summer residents include 115 

 species. Those occurring chiefly or entirely as migrants are 75. 

 The winter residents and winter visitors of fairly general or regular 

 occurrence include 40 species. The accidental visitors, casual visi- 

 tors and stragglers include 67 species, and the remaining 4 species 

 formerly occurred but are now extinct, 3 utterly extinct and the 

 other one extinct so far as its occurrence in the northeast is con- 

 cerned." A synopsis is given showing the status of the various 

 species, enumerating the different permanent residents, summer res- 

 idents, migrants, winter visitors and stragglers. There is a chapter 

 devoted to the faunal areas to accompany the map which appears as 

 a frontispiece for the book. Then follows a partial list of various 

 books and periodicals, which contain articles relating more or less 

 directly to the birds of Maine. There is a complete and satisfactory 

 index which renders the book accessible for ready reference. 



Mr. Knight has put a great amount of time and thought into 

 the preparation of this volume. He has produced a book which 

 will be invaluable to Maine bird students, and which will readily 

 supply the need of all other manuals so far as local bird study is 

 concerned. The author has collected a great mass of material, 

 which in general has been handled with the utmost skill. From the 

 fact that the book was begun several years ago, a few migration 

 dates may need revision, which can be easily accomplished if a sec- 

 ond edition becomes necessary. As a matter of fact, in so exhaust- 

 ive a work, written by a man who is so thoroughly conversant with
