ing on special phases of the habits. Migration notes should be sent to 

 Mr. J. E. Dickinson, 1122 S. Winnebago St., Rockford, 111., as soon as they 

 can be prepared for him. Do not make the mistake of thinking that 

 your notes are too few or too fragmentary to be of any use. The most 

 fragmentary ones may furnish the missing link in the scheme of migration. 



There is yet ample time in which to study the nesting of many of the 

 Warblers. The time occupied in building the nest, the order of deposition 

 of the eggs, the period of incubation, the part played by the different 

 sexes in incubation, the length of time after hatching before the mother 

 ceases to brood over the young in the nest, the time when the young leave 

 the nest, and many other not less interesting facts about the nesting of 

 the Warblers need more light thrown upon them. Mr. H. C. Higgins, 

 Cincinnatus, N. Y., will be greatly pleased to receive your notes relating 

 to nesting. 



. The subjects of food and song may not seem related, and yet they may 

 be profitably studied at the same time. The manner and duration of song 

 can be studied and described by anyone. An intelligent description of 

 a Warbler song is not so simple. Not only should the diurnal period of 

 song be studied, but during the season as well. The beginning, duration 

 a*nd end of the song during the day as well as during the season, it is im- 

 portant to record. Food habits and manner of feeding are not difficult to 

 study : and a record of the contents of stomachs can be made by those who 

 may be working with fresh specimens. Indeed it should be the sacred duty 

 of everyone to carefully record the contents of the stomach of every bird 

 which he may secure. By never neglecting this duty he will never use- 

 lessly sacrifice the life of any bird, and at the same time be of service to 

 science. Notes relating to song and food should be sent to Mr. Lynds 

 Jones, Oberlin, Ohio. 



While studying the Warblers, we must not forget that there is much 

 yet to be learned about the Flicker. It is not so much the curious and 

 exceptional things that we want to know about our commoner birds, as it 

 is the things of every day occurrence which we may suppose everybody 

 already knows all about. Whatever you may know about the habits of 

 the Flicker, even to the commonest details, will be gladly received by 

 Mr. Frank L. Burns, Berwyn, Penn. 



But there is a field of entirely new and original investigation, in which 

 anything you may learn will be new both to yourself and to others. I 

 refer to Nestling Down, a subject which has been taken up by Mr. 

 Howard P. Mitchell, Mt. Sterling, Wis., to whom any and all notes 

 should be sent. It is a subject well worth your time and attention.
