Dendroica maculosa. BULLETIN OF THE NUTTALL ORNITHOLOGICAL CLUB. Vol. II. JANUARY, 1877. No. 1. THE BLACK-AND-YELLOW WARBLER (DENDROICA MACULOSA). BY WILLIAM BREWSTER. FIRST impressions are apt to be most lasting, and in many cases are engraved upon the memory with a vividness that defies the effacing influence of time. Thus the Black-and-Yellow Warbler was one of my earliest bird acquaintances, and I shall not soon for- get our introduction. My family was spending a few days in a quiet little country town in New Hampshire, when, one hot summer afternoon, finding time hang heavily on my hands, I borrowed an old gun, and at the coun- try store, where everything was sold from a patent coffee-mill to the latest specific for rheumatism, I purchased a supply of am- munition, and, thus equipped, took to the woods and searched a long time in vain for game. At length, entering a grove of thickly growing young spruces, I sat down to rest on a mossy log. I had been there but a short time when I became conscious of faint sounds in the trees above and around me, — chirpings, twitterings, and occasionally a modest little effort at song. Watching atten- tively, I soon spied a movement among the branches, and a tiny bird hopped out into the light, presenting a bright yellow breast and throat for just a moment before flying into the next tree. Here was a revelation ! I already knew a few of the most familiar birds, — the Robin, the Bluebird, the Sparrow, the Oriole, and some others ; but it had never occurred to me that dark forests like these might be tenanted by such delicate and beautiful forms.
