15 Birds That Build Mud Nests

Birds that build mud nests

Birds that build mud nests have always fascinated both nature lovers and birdwatchers. Using materials like mud, grass, and leaves, these birds craft nests that are not only functional but also works of art in their own right.

Whether it’s the agile Common House Martin or the stunning Black-billed Magpie, each of these birds showcases a unique blend of architectural skill and adaptability.

The world of these amazing birds will be explored in this article. You’ll learn about where they live, how they build their nests, and some cool facts along the way. So, let’s get started and learn more about these mud-loving birds!

15 Birds That Build Mud Nests

1. Hamerkops

Scientific Name:Scopus umbretta
Conservation Status:Least Concern
Length:18.5–22 in (48–55 cm)
Weight:14.6–15.1 oz (415–430 g)
Wingspan:35.4–37 in (90–94 cm)
Lifespan:Up to 20 years

The Hamerkops is a wading bird known for building big mud nests. Found in places like Africa and Madagascar, they love to be near water, like lakes and rivers.

What makes Hamerkops particularly fascinating is their nesting behavior. They use sticks and mud to build huge dome-shaped nests. These aren’t just any nests; at up to 6.5 feet wide, they’re some of the biggest bird nests in Africa!

But that’s not all. These birds have a head that looks a bit like a hammer, which is how they got their name. So, if you ever see a bird with a hammer-shaped head near water, you might just be looking at a Hamerkop.

2. Apostlebird

Weight:3.8–4.5 oz (110–130 g)
Wingspan:12.5–14.1 in (32–36 cm)
Lifespan:Up to 25 years

Native to Australia, the Apostlebird is a notable mud nest-building bird and is sometimes called a grey jumper for their hopping gait.

These medium-sized dark gray birds are known for their unique social behavior, often seen in groups of 12, which is how they got their name from the biblical Twelve Apostles.

These birds love places with trees and are often found in woodlands or on farms. They are ground feeders, primarily munching on insects and seeds.

One of the most intriguing aspects of this bird is its nest-building habit. Using mud and grass, they build sturdy nests high up on the horizontal branches of large trees, providing a safe haven for their young.

The Cliff Swallow is a North American bird known for its social nature and mud-nest-building habit. These birds are often spotted in large colonies, with some sites even hosting thousands of nests.

During one of my field studies in Mexico, I observed a colony of Cliff Swallows up close. Their synchronized flight patterns were amazing to watch.

Nestled under a rocky overhang, they skillfully crafted their mud nests, showcasing nature’s architectural genius. Each nest is meticulously built with mud pellets and covered with grass and feathers for extra warmth.

They are most at home in wide-open areas, especially those close to cliffs, river bluffs, and lakes. Interestingly, they’ve also adapted to human-made structures, building their nests under roofs, bridges, and overpasses.

Apart from their nesting habits, Cliff Swallows are easily recognizable by their white foreheads and dark brownish plumage with hints of red.

Another bird that builds nests out of mud is the Purple Martin, which is also regarded as the largest swallow in North America.

These birds, like other birds with purple feathers, are famous for their glossy, purplish-blue plumage. They are also known for their aerial acrobatics as they skillfully catch flying insects in midair.

In terms of habitat, Purple Martins prefer open areas near wetlands, swamps, and wet meadows. They often build their nests in dead trees, cliff edges, tree hollows, or even in birdhouses in people’s yards.

Moreover, they are communal birds and can often be seen nesting together in colonies.

Their unique nesting behavior, combined with their captivating appearance, makes the Purple Martin a popular subject among bird watchers and researchers alike.

The Common House Martin is not just a master at building mud nests but also adept at being a migratory bird. These birds travel far and wide, spending the colder months in warmer climates and flying back home in time for nesting season.

They build their nests on the outside of buildings, usually beneath the roof eaves, using mud they collect from ponds and streams.

These places not only offer protection but also make it easier for these birds to access their nests during their frequent in-and-out trips. Moreover, they usually choose to nest in colonies, creating a tight-knit community of nests.

Apart from their nesting habits, Common House Martins are also known for their swift flight and aerial acrobatics. They dart and weave through the air with amazing precision, performing complex maneuvers.
