Zeitgeber light. All our green clocks
begin to whirr. Molecular tick, protein tock.

Spring rises from within, endogenous
rhythmic shifts, a secret tic

released by light. Bare branches, blind,
see sun’s change. The inner talk

of cryptochrome and melanopsin, rise and fall
of cycles, dawn to dusk, root to tip.

April’s relentless pastorale. Caragana buds
ruff out, silver lambs. Sparrow cross-talk.

Even through the icy nights, ice wants to melt
from within. Water’s constant drip and tick.

Et in Arcadia ego. Spring’s alarm sounds brng!
brng!  Bring your dead sticks and stalks.

Time will bury them in green.
