Challenges and Threats to Nesting
Natural Predators and Threats
Nesting is a risky time for birds, especially because they cannot simply move their nest or eggs when danger strikes. The following threats are common causes of nest failures in both wild and developed environments:
- Predation by other birds, mammals, reptiles, and humans
- Extreme weather events like strong winds and hail
- Wildfires
- Trampling by livestock and other large animals
- Flooding
- Removal and destruction by humans during tree felling, etc.
Human Intervention
The use of pesticides like DDT had devastating impacts on nesting birds in the mid-1900s, and its use is still permitted in parts of the world affected by malaria.
Disturbance caused by recreational activities like motorsports and even hiking can also deter nesting birds, so it's important to remain sensitive to nesting birds and limit our disturbance in their natural environments.

The Purpose Behind Nesting
Nesting: Beyond a Shelter
A bird’s nest provides a few essential functions. Firstly, the nest provides a safe surface where the eggs can remain together without rolling away, falling and breaking, or being covered in water. Nests may also provide an insulating effect to keep the eggs’ temperature stable during incubation.
Nests help to camouflage eggs, and chicks, and incubate adults to keep them safe from predators. They are often carefully built from soft materials to provide a nurturing environment for the growing chicks and a comfortable and sheltered space for the adult.

Diversity in Nesting Habits
Varying Architectures
The classic bird’s nest is somewhat cup or bowl-shaped, with a rounded profile when viewed from above or below. This shape prevents the eggs and young chicks from falling from the nest while providing a platform where the adult birds can incubate in safety.
However, nests come in a surprising array of shapes and sizes. Many ground-nesting birds scrape away at the soil or sand to create a slight depression, which they may or may not line with other materials.
While most nests are somewhat 2-dimensional, many birds build ball-shaped nests, complete with walls and a roof. These nests may be positioned on a surface or hang suspended below some kind of anchor point. The entrance to these nests may be from below or the side and some even have false openings to fool predators.

Nesting Material Choices
Birds use various natural and man-made materials to build their nests. Some species will use just about anything they can find, while others source specific materials and use them during particular phases of construction.
Plant matter, like twigs, forms the basis of most birds’ nests, but you might spot any of the following materials in a nest, depending on the species that built it.
Plant materials
Animal materials
- Animal hair
- Feathers
- Spider webs
- Sea shells
- Bird saliva
Inorganic and artificial materials
- Mud/clay
- Plastic
- Thread
- Paper
Nesting Habits
Have you ever pondered on whether the egg or the chicken came first? Well, perhaps it was the nest.
A bird’s egg is a fragile life form. If incubated correctly, it takes anything from a few days to a few months to hatch. After hatching, some baby birds leave the nest on their first day, while others may spend many weeks before taking their first tentative flights. For most species, this process requires the shelter and protection of the nest.
While they may all have the same basic function, not all nests are created equally. Some are little more than a few scratches in the dirt, while others are highly complex and masterfully built structures. This guide uncovers the fascinating world of bird nests. Read along to learn more about their purpose, construction, and why it’s so important to protect nesting birds.
