An especially good field for studying the warblers during their 

 migrations is in the higher timbered region of DuPage County, in 

 the northern portion of our area. Here we also have as summer 

 residents the Warbling Vireo ( Vireo gihus) , the Yellow-throated 

 Vireo {Vireo Havifrons), and the Black-throated Blue Warbler 

 (Dendroica ccerulescens) . While about the region of Chicago 

 with its chains of lakes divided by long ridges of timber may be 

 found all of our more common forms of bird life in abundance. 

 The fine city parks of Chicago are the most favorable localities 

 in which the birds may be studied with a field glass. The wooded 

 island in Jackson Park is an excellent place for the study of the 

 water loving passeres, such as the Prothonotary Warbler, Water 

 Thrushes and Swamp Sparrows. Lincoln Park (see plate II) 

 one and one-half miles long, bordering on Lake Michigan, with 

 its lagoons and lakes, numerous wooded knolls and hills, is a 

 wonderfully attractive locality for the study of birds. On Septem- 

 ber i8, 1894, in one small patch of bushes near the greenhouse, 

 I found twelve specimens of the Connecticut Warbler. 



To show what an excellent locality Lincoln Park is for the 

 study of birds I desire to call attention to the work of Professor 

 Herbert Eugene Walter, of the Robert A. Waller High School, 

 in Chicago, who published a little book, "Wild Birds in City 

 Parks." This, valuable little work consists of hints on the identi- 

 fying of 14s birds, which he has observed and studied during the 

 spring migrations in Lincoln Park. The object of this book is 

 to furnish those who may be interested in making the acquain- 

 tance of wild birds with a simple letter of introduction to these 

 birds, the majority of which are commonly seen during the spring 

 migration. 



It would be a difficult matter to. find a more interesting and 

 fertile field for the study of birds than our area. The great wooded 

 region north of us; Lake Michigan on the east; the desolate 

 sandy southern portion, somewhat resembling the western plains 

 and upon which there, are found growing quite a number of 

 western plants and the prickly pear cactus {0 puntia, rafinesquii) , 

 the whole area forming an attraction for birds which favor such 

 localities. What greater inducements could be offered birds to 

 visit our area during their migrations, for south and west of us
