Right now Blue Jays are looking for seeds and nuts they can cache to help them survive over the winter. They store food in locations up to four kilometers away from their source. In one study Jays were seen making up to 1000 trips per day to gather food and hide it in a safe spot. They are in search of high energy, high protein foods that include peanuts in the shell, sunflower seeds, acorns, and other nuts. One Blue Jay was observed packing over 100 sunflower seeds into its gullet during just one visit to a feeder. Jays are known to shake peanuts in the shell at bird feeders to see if they are full or empty so they don't waste time and energy carrying an empty shell to store. For a bit of fun, here is a link to an online Blue Jay jigsaw puzzle -
