213 [515] Pinicola enucleator leucura (Mull.). 



Pine Grosbeak. 



Irregular and at times abundant winter visitor. October 27 to March. 



In the last fifteen years I have few records of this bird in Essex County,

 Purple Finch. 



Permanent resident, common in summer, rare in winter. April i to Novem- 

 ber 5 ; winter. 



Eggs: June 8 to June 19.

 and then with wings stretched up at an angle of 45° he floats slowly down still

 a tree. 



Dr. J. C. Phillips described to me, in a letter of May 23, 1915, the courtship 

 display of this bird which " stood on the ground before the female very upright 

 with extended wings waving back and forth over the back very fast." Olive 

 Thorne Miller^ says : " Even the charming Purple Finch expands his plumage and 

 executes a dainty and exquisite graceful dance."
