Mrs. Osgood Wright tells a pretty incident of the Chickadees, thus: "In the winter of 1891-2, when the cold was severe, the snow deep, and the tree trunks often covered with ice, the Chickadees repaired in flocks daily to the kennel of our old dog Colin and fed from his dish, hopping over his back and calling Chickadee, dee, dee, in his face, a proceeding that he never in the least resented, but seemed rather to enjoy it." PROTHONOTARY YELLOW WARBLERS. Quite a long name for such small birds--don't you think so? You will have to get your teacher to repeat it several times, I fear, before you learn it. These little yellow warblers are just as happy as the pair of wrens I showed you in April "BIRDS." In fact, I suspect they are even happier, for their nest has been made and the eggs laid. What do you think of their house? Sometimes they find an old hole in a stump, one that a woodpecker has left, perhaps, and there build a nest. This year they have found a very pretty place to begin their housekeeping. What kind of tree is it? I thought I would show only the part of the tree that makes their home. I just believe some boy or girl who loves birds made those holes for them. Don't you think so? They have an upstairs and a down stairs, it seems. Like the Wrens I wrote about last month, they prefer to live in swampy land and along rivers. They nearly always find a hole in a decayed willow tree for their nest--low down. This isn't a willow tree, though. Whenever I show you a pair of birds, always pick out the father and the mother bird. You will usually find that one has more color than the other. Which one is it? Maybe you know why this is. If you don't I am sure your teacher can tell you. Don't you remember in the Bobolink family how differently Mr. and Mrs. Bobolink were dressed? I think most of you will agree with me when I say this is one of the prettiest pictures you ever saw. [Illustration: From col. Chi. Acad. Sciences. CHICKADEE. Life-size.] [Illustration: From col. Chi. Acad. Sciences. PROTHONOTARY WARBLER.] THE PROTHONOTARY, OR GOLDEN SWAMP WARBLER. The Golden Swamp Warbler is one of the very handsomest of American birds, being noted for the pureness and mellowness of its plumage. Baird notes that the habits of this beautiful and interesting warbler were formerly little known, its geographical distribution being somewhat irregular and over a narrow range. It is found in the West Indies and Central America as a migrant, and in the southern region of the United States. Further west the range widens, and it appears as far north as Kansas, Central Illinois, and Missouri. Its favorite resorts are creeks and lagoons overshadowed by large trees, as well as the borders of sheets of water and the interiors of forests. It returns early in March to the Southern states, but to Kentucky not before the last of April, leaving in October. A single brood only is raised in a season.
