Something deep within me sings When you go by with whir of wings, For this one hour you are free From cage's bars and boundary.
I feel something within me soar When you flash thru your open door And fly with softly rolling song— But you, as well, for home soon long!
A speaker watches a bird pass by, wings whirring, and feels a surge of gladness. The bird has slipped out of its cage, and for one hour it is free. Watching it, the speaker feels something rise inside, as if the bird's flight were carrying a part of the speaker along with it. The open door, the flash of movement, and the softly rolling song all make the moment feel light and joyful.
The last line adds a gentler note. The speaker suspects that the bird, for all its freedom, will soon long for home. That small twist complicates the happiness. Freedom here is sweet but brief, and the cage, while it confines, is also a place of belonging. The poem seems to suggest that the speaker shares the bird's double feeling: the thrill of flying off and the quiet pull of returning. The mood is bright and tender, touched with a hint of longing.
