Bird's Nestling
A combination of characteristics and actions helps baby birds keep dry in the nest during rain:
1. Nesting Material: Many bird species construct nests from materials that are both insulating and waterproofing. Grass, feathers, leaves, and even spider silk are examples of these materials. The nest structure itself aids in water shedding and keeping the interior somewhat dry.
2. Nest Design: The shape and design of the nest can aid in the diversion of rainwater away from the inside. Many bird nests feature a domed or cupped design to keep water from accumulating inside.
3. Parental Care: Adult birds are extremely important in safeguarding their nestlings from rain. They may shelter the chicks from rainfall and deflect water away from the nest with their bodies. Parent birds have oil glands that let them to preen and coat their feathers in waterproof oils. These oils keep water from penetrating their feathers and transferring on to the chicks.
4. Feather Development: As newborn birds mature, their feathers begin to form. Feathers provide insulation and aid in water shedding, keeping the chicks dry. Water can be repelled by even partially formed feathers.
5. Huddling: Nestlings may snuggle close in the nest in some situations, which helps to generate a warmer and drier microclimate. The chicks' combined body heat can help to decrease moisture buildup inside the nest.
6. Nesting Location: Some bird species build their nests in protected areas, such as under overhanging branches or in tree cavities. This natural cover provides additional rain protection.
While these processes serve to shelter fledgling birds from rain to some extent, severe or continuous rain can still be a challenge. In such instances, the ability of the parents to offer warmth and safety becomes even more important. If you stumble across a nest with baby birds during rainy weather, it's better to observe from a distance and avoid disturbing the nest, as the parents are most likely caring for their young.
