A black-capped chickadee weighs about as much as a few sheets of paper. In a single autumn, it will hide tens of thousands of seeds, one at a time, in separate spots scattered across the forest. Then, all winter, it finds them again.
To pull this off, the bird's hippocampus, the brain region involved in spatial memory, undergoes a surge of new neuron growth during the caching season.
That still fascinates neuroscientists. For much of the 20th century, scientists believed adult brains could not make new neurons at all. Research on birds such as chickadees helped show that assumption was wrong.
So the little gray bird at your feeder in January is relying on a memory system that has been actively reshaped over the previous few months. For a creature that weighs less than half an ounce, it's one of the most impressive feats of memory in the animal world.

It’s important that you understand what happened last night.
Last night, Stephen Colbert interviewed Democratic Texas Senate candidate James Talarico, a candidate who, by all accounts, is on track in the polls to flip Texas blue.
In response, Trump’s FCC reportedly threatened CBS if the interview aired.
CBS caved and pulled the segment, citing “financial reasons.”
In modern American history, no president has been more hostile to free speech than Donald Trump.
But censorship always backfires.
Here’s the full segment Trump didn’t want you to see.
This is Archie. Just came from an epic day of zoomies and fetch at the park. Now waging a heroic battle against sleep in the backseat, complete with legendary head bobs and crossed eyes. Pure determination. would tuck him in 🐶💤
@ByJasonFoster I feel old when I wake up. But I remember being out flying kites as a kid living in Florida and watching that happen. Sprinted home and never left the tv until bedtime.
