I'm reading the ee cummings poem "i sing of olaf glad and big". I need to annotate for school, but I don't under stand what the term "silver bird" is? The poem is about the military, so i figure it is some kind of military term.
Here's the stanza:
"straightway the silver bird looked grave
(departing hurriedly to shave)"
and the entire poem can be found here: http://www.poets.org/viewmedia.php/prmMI…
if anyone can help, that would be great! thanks!
