These Migratory Birds -...Remains Mysterious

They come on holidays, Like we go with our families To our favorite place Time and again Every winter, they fly, million miles Crossing many boundaries, Mountains, forest, rivers, ponds Roads, bridges everything on their way To reach their destination At some remote place Where the pond awaits Desperately to greet them And when they arrive at pilgrimage place The fresh fishes are served And they forget the perilous journey The pain and fatigue vanishes soon Some are here for breeding Some are here to perform rituals They only know what they gain But to us it is a wonder that remains mysterious
