Wondering about a poet...

[ELEMT]

Hi! Recently in a book (which, of course, I cannot remember the name of), I found a poem that I really enjoyed. I'm almost certain the poet was Mark Van Doren, and the poem was about a bird guarding an onlooker's garden. The last line was "I hung the gourd he guards from me". If any one knows where I can find this poem, I would really appreciate it. I have used several search engines, and nothing seems to come up. Thanks!
