Hummingbirds get my vote for most amazement per pound. They’re swoopy and freeze-framey and often iridescent, and I love it when one shows up.
Here are the words to the iambic-septametric double acrostic:
Bodacious Sugar-Water hits the spot like half&half
It’s rocket fuel to take a guy as high as a giraffe
Right now this little roustabout has hit the motherlode
Determined to drink up till he’s as gravid as a toad
& soon he’s fully on his way with energy to spare
A happy hovercraft who goes with glee out on a tear
