Woodpeckers and other wildlife are known to store food that they plan to eat later. Caching behavior can be observed year-round, but it is during autumn and winter when I notice an increase in the frequency of this activity.
On the south side of Chicago, I walked across snow-covered sand on an icy lakeshore. The ice that had formed where water met beach lowly creaked as water moved underneath it. The winter day was cold, but, thankfully, there was a lack of wind whose harshness would have only been magnified by traveling across Lake Michigan.
