Birds, Berries and Germination
Some plants have evolved fruits with edible flesh that attract birds. When birds swallow the fruit, they also ingest the seeds. They transport the seeds to new spots for the plants to take root. Birds’ digestive systems grind away the hard outer coating of the seed, making it more likely to germinate. Seeds in a bird’s droppings are pre-packaged in nutrient-rich fertilizer.
