Birds warned of food shortages by neighbor birds change physiology and behavior to prepare:
Songbirds learning from nearby birds that food supplies might be growing short respond by changing their physiology as well as their behavior, research by the Oregon State University College of Science shows.
After receiving social information from food-restricted neighbors for three days, the red crossbills in the study raised their pace of consumption, increased their gut mass and maintained the size of the muscle responsible for flight when their own eating opportunities were subsequently limited to two short feeding periods per day.
Findings of the study by OSU's Jamie Cornelius, published in the journal Proceedings of the Royal Society B, suggest that birds can use social information about food shortages to effect an adaptive advantage for survival.

Not PB. When I was a kid (1960s) my parents bought minimally-processed crystallized honey from a particular apiary. It came in a metal can that resembled a gallon paint can, but had a plated surface (maybe tin plate?) Had the same kind of lid that had to be pried up, we used the end a spoon (instead of a screwdriver!) Family of 5, lasted something like a year.
Hadn't thought about bulk honey in years, looks like the apiaries have moved to 5 gallon plastic containers (I call these "pickle barrels") https://www.champlainvalleyhoney.com/55-lb-Pail-of-Raw-Naturally-Crystallized-Honey_p_57.html [champlainvalleyhoney.com]
