Wildlife Torpors (one-night “hibernations”)

Two mini-hibernations I observed in the garden today:

At morning prayers (a bit earlier than usual, well before sunrise), I heard a noisy motorcycle revving its engine, and spluttering and revving and spluttering, and revving hard and long, successfully getting started… from up in the top of a coast-live oak. After its successful start, the engine abruptly aborted and ended in a couple of clear, hummingbird chirps, and then the hummingbird, now fully awake from its nightly hibernation, flew off to hunt for breakfast.

And tonight, while we were eating dinner as darkness was falling, a giant mama, yellow-faced bumble bee flew to a blueberry bush just outside our dining room window (single-pane glass allows some of our heat out to warm that bush at night, and the first rays of morning sun warm it in the morning), and after pumping her abdomen for a wee bit, trying to stay warm, she curled into a tight little ball huddled beneath a blueberry leaf, and turned to stone – hibernating for the night.

What a wonderful cold weather warning system.

Time to put on an extra layer of heavy, merino woolen-wear!
