Eastern Bluebirds also build nests in cavities, like old tree holes or birdhouses. They use grass and feathers to make a soft spot for their eggs. The parents work together too, bringing food to their young once they hatch.
These caring habits are important for the birds' success. When the parents share the work, the chicks grow faster and are more likely to survive. It's amazing to see how these birds and their blue eggs are part of a big cycle of life.
