a thimble of bird with the lungs of an opera house

means A tiny, round-bodied songbird, often with a cocked-up tail and a song startlingly loud for its size.

from From Old English 'wrenna,' a word of murky Germanic stock — its kin appear across the old North Sea languages, though scholars can't trace it to any clear deeper root. In British folklore the wren was the 'king of birds,' supposedly winning the crown by hiding in the eagle's feathers and flying higher than any — a tale that long outlived any solid account of where the name itself was born.
