The Birds of Wyoming. 



way's Manual of North American Birds. With this purchase 

 the latest check list of the A. O. U., and become a member of 

 the American Ornithologists' Union. Then with this bulletin 

 to tell you what has been done with the birds of Wyoming you 

 are ready to commence work. I would recommend that you 

 commence to make a collection of skins immediately, for in no 

 other way can you accumulate really valuable data. There are 

 numerous small publications that will explain in detail how to 

 make bird skins. 



As soon as you commence to study, do not think that you 

 will have to quit work to study birds. Get up before the sun 

 in the morning and about your own home you will find ample 

 material to keep you busy for several seasons. Then upon your 

 vacations and holidays you will always find ample time to add 

 data to your collection. Provide yourself with a large note book. 

 Do not simply note that you have seen a certain species or that 

 you have captured one ; but take careful notes on migration, 

 nesting, food habits and every phase pf a bird's life. In this 

 way you will within the space of a few years, if you are diligent, 

 accumulate a large amount of very interesting and valuable 

 data.

 with a few groups ; but on the whole one can very soon learn 

 to recognize the most of the birds that he meets. When there 

 are difficult specimens, as for instance the sparrows, it is al- 

 ways advisable to call upon some one that has a large collection 

 of skins that are properly identified, for comparison. The 

 university will always be glad to grant any aid it possibly can 

 to those in the state who will study the birds. When there are 

 difficult problems to solve I would recommend that the skin be 

 sent to the National Museum or to the Department of Agri- 

 culture at Washington, D. C, for determination. 



To the citizens of Wyoming, let me ask that they interest 

 their boys in the study of birds. Give them an opportunity 

 to become acquainted with birds, and in learning to study them
