Sur la l3d de mai, continue-t-il, j'ai eu la satisfaction de faire un bruit de coeur à la chanson délicate mais monotone de cet oiseau, comme heusily et intinctivement fouillé chaque gouffre et expandingbud pour des larves et des insectes dans un chêne qui s'étend, d'où l'on a fait sa note solitaire. Parfois, il est resté un minuteou deux stationnaire, mais plus généralement a continué sa quête contre-proie. Sa chanson, en bref un

Onthe l3d of May, he continues, I had the satisfaction of heark-ening to the delicate but monotonous song of this bird, as hebusily and intently searched every leafy bough and expandingbud for larvae and insects in a spreading oak, from whence hedelivered his solitary note. Sometimes he remained a minuteor two stationary, but more generally continued his quest forprey. His song, at short and regular intervals, seemed likeHshee H shay t shaitshee, varying the feeble sound very little, andwith the concluding note somewhat slenderly and plaintivelyraised. It was a good many years before we heard of this Warbleragain. Meanwhile, the systematists were busy with its name, much as usual, bandying the bird about from one genus toanother, but adding nothing whatever to our real knowledge.Drs. Cooper and Suckley met with it in the original locality, orat least in the same general area, and the latter notes that it. HABITS OF BLACK-THROATED GRAY WARBLER 265 g^enerally arrives from the south early in April, is commonlyfound in oak forests, and is rather abundant in the vicinity ofFort Steilacoom. Dr. Cooper saw a pair at Puget Sound whichseemed to have a nest, but he did not succeed in finding it.About the time that these observations were made, we hadsudden word of the species from a distant point in Mexico; forM. A. Boucard secured specimens in Oaxaca, Mexico, as Dr.Sclater soon recorded. To this very day these advices remainthe northernmost and about the most southerly we have; forthe Black-throated Gray has never been traced north of theregion in which it was originally discovered, nor yet throughMexico into Central America. Prof. F. Sumichrast has, how-ever, taken it in Orizaba; and there is much reason to supposethat its actual range is not less extensive than that of e
