Thomas Aird was a Scottish poet who lived from 1802 to 1876. He wrote the following poem about swallows as they returned to his homeland after wintering in Africa. Bird migration happens all over the world. I remember staying overnight at a kibbutz in northern Israel in the spring and seeing flocks of birds resting in the pines and ponds on their migration northward. Tree Swallows are returning here in large numbers. I took pictures of this pair yesterday as they built their nest in the rain.
The swallow, bonny birdie, comes sharp twittering o’er the sea,
And gladly is her carol heard for the sunny days to be;
She shares not with us wintry glooms, but yet, no faithless thing,
She hunts the summer o’er the earth with wearied little wing.
The lambs like snow all nibbling go upon the ferny hills;
Light winds are in the leafy woods, and birds, and bubbling rills;
Then welcome, little swallow, by our morning lattice heard,
Because thou com’st when Nature bids bright days be thy reward!
Thine be sweet mornings with the bee that’s out for honey-dew;
And glowing be the noontide for the grass-hopper and you;
And mellow shine, o’er day’s decline, the sun to light thee home:
What can molest thy airy nest? sleep till the day-spring come!
The river blue that rushes through the valley hears thee sing,
And murmurs much beneath the touch of thy light-dipping wing.
The thunder-cloud, over us bowed, in deeper gloom is seen,
When quick reliev’d it glances to thy bosom’s silvery sheen.
The silent Power, that brought thee back with leading-strings of love
To haunts where first the summer sun fell on thee from above,
Shall bind thee more to come aye to the music of our leaves,
For here thy young, where thou hast sprung, shall glad thee in our eaves.
