Wind can dart through the trees as wind-squirrel: limb after limb
bending while the creature rummages the foliage of hazel or scrub maple,
scuffles amid their branches whose leaves tremble, ends bob and sway.
Other times a wind-bear blunders aloft in tall firs or spruces, thrashes
between the heavy boughs so needles and cones plunge and heave upward.
As a bear will, despite its weight it suddenly becomes agile, leaps pine
top to pine top, each high trunk rocking gravely for several minutes
where the animal landed, clung for an instant, pressed on.
