In addition to it being Friday the Thirteenth, its National Peanut Day, a this national holiday that blue jays would probably like to celebrate everyday, as you might surmise from the photos atop this entry (and directly below) featuring a tenacious fledging trying to grab the what was left in my wreath-style peanut feeder before I replenished it.
Re National Peanut Day, a web-page for nationalday.com states facts about peanuts, reminding their readers,"this legume is not a nut. They grow underground like potatoes. Since they are an edible seed that forms in a pod, they belong to the family Leguminosae with peas and beans."
I dare say jays don't care what family the peanut belongs too as long as they are available in my rooftop garden; as evidenced by the next series of photos taken in bygone years.
While jays do linger in my garden to nosh on a peanut, they often carry it off to the branches within the Ailanthus Trees growing in my courtyard as seen in the next picture.
Other birds enjoy noshing on peanuts in my garden too!
These include Common Grackles ...
