Leave, leave your well-loved nest,
Late swallow, and fly away.
Here is no rest
For hollowing heart and wearying wing.
Your comrades all have flown
To seek their southern paradise
Across the great earth’s downward sloping side,
And you are alone…
—Edwin Muir, “The Late Swallow”
first published in One Foot in Eden (Faber, 1956)
