No. 20.] THE BIRDS OF CONNECTICUT. 187 



Courting antics have been noticed as early (or late) as Dec. 



24, 1903 (L. B. B.). 



New Haven, Dec. lo, 1900, male with lower mandible gone and 

 upper grown to a remarkable length, taken (A. H. V., in coll. of 

 L. B. B.). 



Guiraca caerulea c^rulea (Linnaeus). Blue Grosbeak. 



Connecticut records : May 9, 1902, Bethel, male seen in an 

 orchard (Hamlin) ; summer, 1903, New Canaan, one seen (Mrs. 

 Neide, recorded by Hoyt). 



Vermivora lawrencei (Herrick). Lawrence's Warbler. 



Vermivora leucobronchialis (Brewster). Brewster's War- 

 bler. 



Although it seems now beyond question that the birds called 

 by these names are not independent species, it has not yet been 

 conclusively shown whether they are hybrids between Vermivora 

 pinus and V. chrysoptera, or phases of plumage of these species. 

 Brewster's Warbler completely intergrades with the Blue-winged, 

 while males at least of Lawrence's show usually little variation 

 in plumage. As a very large proportion of the specimens of these 

 puzzling birds so far reported were taken in Connecticut, we have 

 tried to give here a summary of these records. with the addition 

 of others. Brewster's Warbler is much the more common.
