How do you take care of a newly hatched swallow?

To care for a newly hatched swallow, provide a warm and safe environment, as they are highly vulnerable. Feed them a diet of high-protein insects, such as mealworms or specialized bird formula, using a small syringe or tweezers. Ensure they are hydrated by offering water droplets on their beak. It's also crucial to minimize handling to reduce stress and to consult a wildlife rehabilitator for guidance.
