NATURE POETRY

Then the golden hour
Will tick its last
And the flame will go down in the flower.
A briefer length of moon
Will mark the sea-line and the yellow dune.     – Arna Bontemps (1902–73)

    so glad you are telling us about the difference in the beaks,it helps. Also,why does the red-bellied woodpecker not have a red belly but a beautlful red head??? Or,we just never see the belly,is that it?
    thank you for all the beautiful and informative posts,Miles!!!!!!
