The very idea of a bird is a symbol and a suggestion to the poet.
A bird seems to be at the top of the scale, so vehement and
intense his life. . . . The beautiful vagabonds, endowed with
every grace, masters of all climes, and knowing no bounds --
how many human aspirations are realised in their free,
holiday-lives -- and how many suggestions to the poet in
their flight and song!
John Burroughs ,Birds and Poets
There is nothing in which the birds differ more from man than
the way in which they can build and yet leave a landscape
as it was before.
If we could be like this tiny bird,
Just living from day to day,
Holding no bitterness in our hearts
For those we meet on our way...
Gertrude Tooley Buckingham
