EDITORIAL NOTES AND NEWS 



The following individuals, members of 

 the Cooper Club, either now or formerly, 

 are known to the editors of The Condor as

 are doubtless others to be added to the 

 list; regarding these we solicit informa- 

 tion, to the end that our war service records 

 be kept up to date. We propose to use 

 this column for revised lists from time to 

 time.

Those who collect bird-skins would great- 

 ly enhance the scientific value of their spe- 

 cimens if they would determine correctly 

 the age of their birds. This is possible with 

 passerine birds, and some others, up to the 

 eighth or tenth month of their age by obser- 

 vation of the condition of the skull. An ex- 

 cellent demonstration of this method is giv- 

 en by Mr. James P. Chapin in his paper on 

 The Classification of the Weaver-Birds 

 (Bull. Amer. Mus. Nat. Hist., vol. 37, 1917, 

 p. 258, fig. 9). Mr. Chapin's paper also 

 serves to show how important it may be in 

 correctly diagnosing species and higher 

 groups to know the effects of age on plum- 

 age and dimensions of parts. 



Dr. Jonathan Dwight is now putting into 

 final shape for publication a monographic 

 revision of the North American juncos, up- 

 on which he has been engaged for some 

 years past. With such a wide diversity of 

 opinions as expressed in the last two au- 

 thoritative treatments of the genus — Ridg- 

 way, in part i of his Birds of North and 

 Middle America, and the A. O. U. Check-List 

 — another careful analysis of the facts, espe- 

 cially if put forth as a special study rather 

 than part of a more general work, will be 

 welcomed by all who have had occasion to 

 puzzle over the variations in this group of 

 birds. 



Mr. H. S. Swarth has begun a study of the 

 Fox Sparrows, especially as regards migra- 

 tion and local distribution upon the Pacific 

 Coast. The incentive for this work arose in 

 part from the increasing numbers of speci- 

 mens being sent to the Museum of Verte- 

 brate Zoology for identification. While in 

 this manner a large proportion of the skins 

 in Californian collections has probably come 

 under his inspection, he would welcome the 

 opportunity of examining any additional ma- 

 terial now available.

 Island, and latterly of Santa Barbara, Cali- 

 fornia, a life member of the Cooper Club,
