The male Yellow-throat always wears plain marks of recognition on his face. He has a black mask extending across his forehead and back on the sides of his head. The female goes without a mask and is clothed in subdued tints of yellow and brown.
When the Yellow-throat seeks a home, he finds a thick tussock of grass and hides his nest well in the middle. It is my experience that when you want to find his home, it is better not to look for it. If you keep on tramping thru the swamps and swales, some day you will stumble on one when you least expect it. Once I hunted for several days about a swampy place where I heard the Yellow-throats singing. Not a sign of a nest did I find. Whenever I appeared the birds were on hand as if very anxious to aid me in finding their home. After tiring me with their deceit, they sneaked away fifty yards to the nest. A little later in the season I happened to see the father carrying worms and discovered the young Yellow-throats just about to leave home. William L. Finley.

Structurally allied to the Wood Warblers, the Chat has yet such a temperamental affinity with the Catbird, that it is difficult, for me, at least, to dissociate the two birds in thought. Both love the thickets; both excel in song; both plague their neighbors by mimicry; and both alike are dearly provoking bundles of contradictions. The Chat is, perhaps, the greater buffoon, as he is certainly the more handsomely dressed of the two. Beyond this we must consider him on his own merits.
Ten to one you know him, if at all, only as a voice, a tricksy bushwhacker of song, an elusive mystery of the thicket; or you have unconsciously ascribed his productions to half a dozen mythical birds at once. But look more closely. It is well worth the quest to be able to resolve this genius of roguery. Be assured he knows you well enough by sight, for he does not poke and pry and spy for nothing, in the intervals of song. He has still the proverbial curiosity of woman. Seat yourself in the thicket, and when you hear the mellow, saucy Kook, with its whistled vowel, bounded by consonants barely thought of, imitate it. You will have the bird up in arms at once. Kwook, returns the bird, starting toward you. Repeat it, and you have won. The bird scents a rival and he will leave no stem unclasped but he finds him. As the bird alternately squints and stares from the brush, note the rich warbler olive of his upperparts, the gorgeous yellow of the throat and breast, the white brow-stripe and the malar dash, offset by black and darker olive. It is a warbler in color-pattern, a Yellow-throat done larger, but waggish, furtive, impudent, and resourceful beyond any other of his kind.
The full song of the Chat is usually delivered from some elevation, a solitary tree rearing itself above dense cover. The music almost defies analysis, for it is full of surprises, vocal somersaults, and whimsy turns. Its cadence is ragtime, and its richest phrases are punctuated by flippant jests and droll parentheses. Even in the tree-top the singer clings closely to the protecting greenery, whence he pitches headlong into the thicket at the slightest intimation of approach.
The love song of the Chat, the so-called “dropping song,” is one of the choicest of avian comedies, for it is acted as well as sung. The performer flings himself into mid-air, flutters upward for an instant with head upraised and legs abjectly dangling, then slowly sinks on hovering wing, with tail swinging up and down like a mad pump-handle. Punch, as Cupid, smitten with the mortal sickness. And all this while the zany pours out a flood of tumultuous and heart-rending song. He manages to recover as he nears the brush, and his fiancée evidently approves of this sort of buffoonery.
