Ferry — Ox Spring Migration. 37 



A few observations of general interest might have to be 

 pointed out : During one of the cold, raw days in May a large 

 flock of migrating Scarlet Tanagers were partially overcome 

 and were driven to the ground in a large open pasture in 

 search of food. Here scattered about they gave this part of 

 the landscape a decidedly gory appearance and with their 

 scarlet plumage presented a striking spectacle. 



A number of species were abnormally abundant this spring, 

 notably Ruby-throated Hummingbirds (May 5), Mourning 

 and Connecticut Warblers, especially so on May 20, and Red- 

 breasted Nuthatches (S. canadensis). An interesting fact 

 about these Nuthatches was the extreme lightness of the un- 

 derparts. Some days they were profusely abundant, but I 

 cannot remember seeing one in the typical red-breasted 

 plumage of the adult. 



The occurrence of Crossbills (probably Loxia ciirv. minor) 

 on June 8th, and of Pine Siskins on June 12th, is worthy of 

 emphasis because of the unusual lateness of these dates for 

 these species. 



The frecjuency with which the warblers were heard singing 

 during the migration was one of its most interesting features 

 and offered an excellent opportunity for the study of their 

 songs. Some of them are here given. 



Black and White Warbler — Tscc Tscc-Tscc Tscc Tscc — 5 

 lisping, very modulated notes. 



Northern Parula Warbler — Za-Zc-Za-Zcc-Zcc, a buzzing, 

 wiry trill, quickly given. 



Black-poll Warbler — It-tit-tit-tit-it-it-it, seven short, sharp- 

 ly accented syllables, quickly uttered, high pitched and wiry, 

 almost insect like. 



Magnolia Warbler — Whcc Whcc-a-Whee-Whee-a. 



Connecticut Warbler — Ttoec-zvcc-ivec-Tzva-tvcct or Tzva-cc- 

 ec-ee-cc-at; also IVIiif-it-ii'hcata-zi'hcata-titheat. Clear, loud, 

 melodious warbler syllables closely run together and quickly 

 uttered.
