July 4 - 1874 Nantucket living being that came within range. After landing I noticed 9 Sturma frenata flying about near the wharves; during a small boat pulled out, In the course of an hour or two three I had a good opportunity of watching their motions. They both on wings very approp- riately smaller than any others of the Sturina) I flap very quickly continuously they usually glance from a higher elevation than the others (about 30ft.) and if they miss their aim or quickly drop agains frequently falling three or four times in half a minute. When joining they flap their wings quickly like a buzz-saw, their vocal note is loud & high very like that one of Hirundo bcedor. They have also a scolding chatter like S hirundo but much weaker. Although I shot several birds the midst of a flock the sur- vivors showed not the slightest signs of horroing, though they frequently passed within a short distance of of the fallen bird as it lay broken wings or the water. Mr. hummers or- forms one that he seen them in autumn swoop down departedly to the morundo.
