48 BULLHTIN No. 35 



EDITORIAL. 



As results an J not mere promises are most satisfactory, we 

 can only regret the evidences of careless proof-reading in our 

 last issue, and hope for better results hereafter. A better grade 

 of paper will be used, and with aid of members and subscribers, 

 a magazine more and more worthy of patronage and 'preserva- 

 tion will be attempted. The many expressions of confidence 

 and encouragement are appreciated. For lack of space in this 

 issue, an article of some length, entitled "All Day with the 

 Birds" by Lynds Jones, is defered until next number. All de- 

 siring to contribute articles or items of interest for the August 

 number, are requested to do so at an early date, as tne last 

 number to the volume will probably be a special, devoted to 

 bird census entirely. 



Do not neglect to comply with Professor Jones request for 

 migration notes for the dates he names, any season or as many 

 years as possible. It is a disappointment to us also to have so 

 few reply to suggestion appearing in May number, in relation 

 to predominate color phase of Screech Owl. The educational 

 value of looking over and rewritting old and scattered records 

 is not the least of the benefits derived by the amateur ornithol- 

 ogist in co-operation study. 



The propensity of the Blue-winged Warbler HelmintJiophilu 

 piniis to form "misalliances, or in other words, to mate with 

 individuals of other closely related species. Is again examplified; 

 this time in connection with the Nashville Warbler, H. rtificapilla. 

 The instance related in this issue by Mr. HoUister, is I believe, 

 the only record of crossbreeding by the latter species. With 

 H. pinus if has been otherwise. It has been long suppected; 

 and at irregular periods there have appeared accounts in the /iuk 

 from which one may gather'apparently conclusive evidence of its 

 interbreeding with the Golden-winged Warbler H. chrysoptera, 

 Brewster's Warbler H. leucobroncliialis, and probably the Ken- 

 tucky Warbler Geothlypis fonnosa; Lawrences' Warbler H. 

 lawrencei being considered a hybrid or mongrel of the first and 

 the Cincinnati H. cincinnaiiemis of the last.
