Belted Kingfisher

The belted kingfisher is a rather large bird that is easy to spot — if you know where to look. While all kingfishers were once placed into the same family, recent research has separated them. It appears they aren’t all as closely related as their shared name implies.

3 Amazing Belted Kingfisher Facts

• Sexual dimorphism: Unlike most bird species, the female belted kingfishers have more colorful markings than the males.
• Excavators: Instead of nesting in trees, a pair of mated kingfishers will excavate a tunnel into a sandy bank at a slight uphill angle. They will nest at the end of this tunnel. They dig it uphill to create an air pocket should the tunnel flood.
• Territorial: In the mating season, these birds can become quite territorial. In some cases, they may even dive at humans.

Where to Find the Belted Kingfisher

The range of this species can be a bit confusing. Not all belted kingfishers migrate, but some of them do. There are areas where these birds stay year-round and others where they must migrate.

They will need to cross most bodies of water in North America. These waters can include the ocean, ponds, and lakes. They simply have to be close enough to fish.

Belted Kingfisher Nests

This species has a strange nesting behavior. They do not nest in trees like other birds. Instead, they dig tunnels into the side of a riverbank or sand bank. Both parents take part in this work. Once the tunnel is done, the female lays eggs, and the parents take turns incubating them.

Scientific Name

The belted kingfisher’s scientific name is Megaceryle alcyon. Originally, the bird’s scientific name was Alcedo alcyon. However, it was changed in 1848.

Megaceryle comes from the words “mega” and “ceryle,” an existing genus. The term “alcyon” means “kingfisher” in Latin.

Therefore, the genus Megaceryle is simply a genus for larger kingfishers. These birds appear throughout the world and contain four different species.

The belted kingfisher’s family is Alcedinidae, commonly referred to as the kingfisher family. As you’d probably guess, this family contains kingfishers of all shapes and sizes. In total, there are 19 genera and 114 species.

Size, Appearance, & Behavior

The belted kingfisher is rather large, though it technically falls into the “medium” category as far as birds are concerned. It measures between 11 and 14 inches with a wingspan of 19 to 23 inches. It can weigh anywhere from 4.0 to 6.3 ounces. Often, the females are slightly larger than the males.

This species has a long black bill that is used for catching fish. Its large head has a shaggy crest, common in many kingfisher species.

Furthermore, this species also exhibits reverse sexual dimorphism. In other words, the females are larger and more colorful than the males — the opposite of most species. Both genders have a blue head, a blue band around their breasts, and a white collar. The back of their wings and bodies range from dark grey to slate blue.

The females have another band across their upper belly that is described as orange or rust.

The juveniles are very similar to the adults. However, they all present as females until they reach sexual maturity. The red band is often mottled in juvenile males, while the band can be smaller in juvenile females.

Often, you can spot this bird perched at a high post or vantage point close to the water. It will watch for fish from these points before diving into the water to catch them. When not hunting, the bird often flies around and makes a rattling call.

Belted Kingfisher Migration and Timing

While some birds migrate on a particular schedule, the belted kingfisher doesn’t fall into this category. Instead, only some birds migrate, usually as the water begins to freeze. If the water never completely freezes, individual birds usually don’t migrate. Birds near the coast in northern areas may never migrate if the sea remains accessible.

Of course, when a bird migrates will depend on when the water freezes in that area. Where the birds go also varies, though they seem to return to about the same point yearly. However, this varies greatly, as some individuals seem to go far out to sea and end up on islands or even in Europe.

In southern areas, belted kingfishers sometimes migrate. However, this doesn’t occur every year, and we don’t know exactly what causes them to occasionally migrate.

Belted Kingfisher Diet

The belted kingfisher gets their food mostly by fishing. However, they don’t just eat fish. Instead, they have slightly opportunistic feeding behaviors and tend to eat whatever is available.

What does a belted kingfisher eat?

For the most part, these birds eat fish. They will wait from a high point near the water until they spot a fish they can catch. However, these birds also eat a variety of other prey items, such as amphibians, crustaceans, insects, reptiles, and small mammals. In this way, they are slightly opportunistic.

Typically, these birds will look for food by the water. Often, this means fish. However, if another animal proves to be an easy snack, they will take the opportunity.

Predators, Threats, and Conservation Status

Currently, the belted kingfisher falls into the least concern category. There doesn’t seem to be a major decrease in their population, which currently stands at around 1.8 million individuals.

While this may seem small, these birds are territorial. Therefore, there is a limit to how many birds the land can support. Plus, they may live by the water, which further decreases where they can live despite their large range.

What eats the belted kingfisher?

For the most part, belted kingfishers are only hunted by hawks. When chased by a hawk, these birds will dive into the water repeatedly until the hawk gives up. However, snakes and some mammals, such as cats, can also eat these birds.

Reproduction, Young, and Molting

After mating, a pair of belted kingfishers will dig a tunnel into the side of a bank. This tunnel is tilted slightly uphill and often quite long. While we don’t know exactly why they dig uphill, this provides an air bubble in case the tunnel floods. The chicks can stay within this air bubble and survive.

After the tunnel is done, the female lays five to eight eggs. The adults take turns sitting on the eggs and feeding the young. During this time, the birds can be extremely territorial. They will chase away predators and other birds. Sometimes, they may even chase people.

The incubation period is long, lasting between 22 and 24 days. Often, the nestling period is equally as long, at around 27 to 29 days. As the babies are fed, fish bones, scales, and other debris accumulate, which helps shelter the babies more.

Population

Currently, the belted kingfisher population remains steady at around 1.8 million birds. However, extensive and recent population studies have not occurred.
