THE OOLOGJST 



tion it has been decided to give our 

 principal attention to the Warblers. 



There are thirty-six species of war- 

 blers known in Michigan, and one var- 

 iety. The listing of the yellow-throat- 

 ed Warbler. Dendroica dominica (L.) in 

 Cook's Birds of Michigan, 1893, was an 

 error. 



Of these representatives of a most in- 

 teresting family, twenty-eight are com- 

 mon and well known to all advanced col- 

 lectors, and twenty two are abundant. 

 Twenty-one are known to breed in the 

 state, and the nesting habits of seven 

 are known to nearly all observers. 

 Four species are stragglers only. Sev- 

 en or more are locally distributed, and 

 not found in many sections. Five are 

 ithought to pass north of our boundaries 

 to nest. Seven are known to remain in 

 the state in summer, yet are not known 

 to breed. 



Notes should be taken at each station 

 as follow: 



1. Date of arrival of first male and fe- 

 male. Date when common. Date at 

 which last specimen of those who pass 

 north was seen. List of summer sojour- 

 ners. 



2. Date of first song. Desci'iption of 

 songs and call notes, expressed in syl- 

 lables. Preferred time of singing. 

 Date of cessation of song. 



3. Date of earliest nesl building. 

 Date of completion. Complete descrip- 

 tion of nest; dimensions; exact situat- 

 ion; with name of tree or bush, descrip- 

 tion of locality, wood, or field, marsh or 

 highland. Full notes on material of 

 nest structure, outside, inside and lin- 

 ing. Weight of nest (avordupois .) 



4. Date of first egg deposited. Date 

 Position of the first full set. Position of 

 the eggs. Number of the eggs. Date of 

 Ihatchlng of brood. Take careful note 

 <of date of deposition of egg of Cowbird, 

 and length of period of incubation of 

 Warbler and Cowbird. 



5. Date when young leave the nest, 

 with special mention of the time when 

 the young Cowbird leaves. 



6. Habits of old bird during incuba- 

 tion and care of young. Food of the 

 .young. Food of the old birds. 



7. Description of eggs. 



8. Date of departure, with remarks 

 on changed appearance from moulting. 

 Date of appearance of northern tran- 

 sients. 



9. Other notes which will be suggest- 

 ed to thoughtful observers by the birds. 



These oDservat,ioQS, if generally and 

 systematicaly taken, will secure to us a 

 better understanding of the Warblers of 

 Michigan than has been our fortune thus 

 far. This State has not received the at- 

 tention from thorough workers which 

 its interesting avi-fauna would seem to 

 invite, and no concerted systematic 

 work has ever been accomplished. 



Systematic observations cannot fail to 

 be of interest to each worker in a local- 

 ity, while the value of a compilation of 

 these notes will be of the greatest assist- 

 ence in future research. To those who 

 wish to study other families or groups 

 of birds, and to all collectors of skins 

 and eggs, we would say that the Aca- 

 demy will be pleased to receive your ob- 

 servations, as well as specimens which 

 you may wish to offer.

[These suggestions are so good, that 

 we cannot do better than to advise col- 

 lectors of other states to follow them in 

 conserted action and later secure com- 

 pilation of the season's efforts. It is 

 only by this means that our best work 

 is accomplished. — Ed.] 



In September will be solemnized the 

 wedding of Dr. R. W. Shufeldt to Miss 

 Florence Audubon, a daughter of John 

 Woodhouse Audubon, the second son of 

 J. J. Audubon, the famous author of the 

 "J5irds of America." May the wedding, 

 so happily appropriate, be ever approp- 

 riately happy ! — Nidiologist.
