I took this video right outside my house on Brickle Ave, about a week or so before spring break. Filmed here are robins (Turdus migratorius) collecting berries off the ground that had fallen from trees (the species of which I couldn't identify). The main ecological concept demonstrated here is the concept of non-symbiotic mutualism. The trees depend on organisms like birds and squirrels to spread their seeds for the means of increasing their fitness, and in return, the trees' helpers are rewarded with a nutritious, fruity snack (the berry). Another fundamental ecological processes demonstrated in this video is the detritus cycle. We're seeing first stage of the cycle, in which organic matter, such as the berries and leaves, are deposited on the forest floor. This organic matter will then be processed and decomposed by an array of micro-organisms called detritivores, eventually becoming incorporated into the soil.
