The belted kingfisher (Megaceryle alcyon) is a medium-sized bird found across North America. With their top-heavy bodies, blue-gray plumage, and raspy calls, these ragged-crested kingfishers are a familiar sight around waterways large and small. But are belted kingfishers endangered? Let’s take a closer look at the status of this iconic bird.
Belted Kingfisher Overview
Belted kingfishers are stocky, short-tailed birds measuring 28-35 cm (11-14 in) in length with a wingspan around 58 cm (23 in). Their ragged crest slopes down to meet a heavy bill, perfect for spearing fish. The male has a single blue-gray band across his white chest, while the female sports a rusty band across her belly.
These kingfishers inhabit areas near calm or slow-moving water across much of North America. They require overhanging branches, steep banks, exposed roots, or human-made structures for their nesting sites. Belted kingfishers feast on small fish, crustaceans, reptiles, amphibians, and insects. They capture prey by plunging headfirst into the water.
Belted Kingfisher Population
According to the North American Breeding Bird Survey, belted kingfishers are abundant and widespread across the continent. Their total population is estimated at 1.3 million individuals. Population trends appear stable with no significant increases or decreases from 1966 to 2015. The species ranks 13 out of 84 kingfisher species worldwide in terms of population, making it one of the most common kingfishers on Earth.
In 1966, the estimated population of belted kingfishers in North America was about 1.5 million. By 2015, the population was estimated to be around 1.3 million. While there has been a slight decline over the past 50 years, the species remains common and the population change is not statistically significant.

Across their range, belted kingfishers inhabit a diversity of aquatic habitats from inland rivers and lakes to estuaries and coastlines. Their ability to thrive in both salty and freshwater ecosystems makes them highly adaptable. As long as their habitat provides adequate food sources and nesting sites, belted kingfishers are likely to persist.
Threats and Conservation Status
While still widespread, belted kingfishers face some threats from human activity. Development near waterways can degrade or destroy their nesting and foraging habitats. Poor water quality from pollution, runoff, and dams can reduce their prey populations. Disturbance from recreational activities may also displace them from quality habitats.
However, belted kingfishers are protected in the U.S. under the Migratory Bird Treaty Act. They have an extensive range and large overall numbers, so the IUCN Red List categorizes them as a species of Least Concern. Their adaptation to human-altered habitats and ability to utilize both saltwater and freshwater areas contributes to their relatively secure status.

While not considered endangered or threatened at this time, it is still important to protect and monitor belted kingfisher populations. Maintaining water quality standards, preserving shoreline vegetation, and restricting disturbances in key habitats can help ensure these birds thrive for generations to come.
Efforts to Protect Belted Kingfishers
Several conservation efforts are underway across North America to protect and manage belted kingfisher populations:
- Habitat protection and restoration along migratory routes and wintering grounds in the southeastern U.S.
- Monitoring of aquatic toxicants that could impact kingfisher prey sources
- Public education programs to reduce nest disturbances
- Citizen science initiatives to track populations and distribution
- Enforcement of regulations prohibiting hunting and nest destruction
While belted kingfishers still face localized habitat loss and disturbance, expanded conservation measures focused on water quality, fisheries, and shoreline management provide hope for the future of these remarkable birds. Their ability to adapt to human-altered environments points to a resilience that should enable belted kingfishers to thrive as long as we make responsible decisions about protecting our shared waterways.
Belted Kingfishers and Humans
Belted kingfishers have a mixed relationship with humans. On one hand, human alteration of habitats often benefits these kingfishers by opening up new nesting sites and fishing spots along man-made waterways, reservoirs, and canals. Their population remains robust in part due to adaptation to human landscapes.
On the other hand, human activity threatens belted kingfishers through shoreline development, degradation of water quality, and disturbance of nesting sites. Careful management of riparian zones is important to maintain viable kingfisher habitats for the future. Reduction of aquatic pollution and preserving natural lake/river shorelines can support healthy ecosystems for both kingfishers and humans.
Responsible birders and anglers should respect nesting kingfishers by minimizing noise and activity near occupied burrows or perch sites during critical spring breeding season. With care and stewardship, we can coexist with and even foster healthy belted kingfisher populations across North America.
Conclusion
In summary, belted kingfishers are still widespread and relatively common across North America. Their populations appear stable overall, though they face localized threats from human activity and habitat loss. While not currently considered endangered, active conservation efforts are needed to monitor and protect kingfisher populations and aquatic ecosystems for the future.
With abundant food sources and suitable nesting sites in both natural and man-made habitats, belted kingfishers demonstrate resilience despite human alterations to the landscape. Their adaptability provides hope that kingfishers can continue thriving alongside responsible development and recreational activities across their range. Protecting water quality, preserving shoreline vegetation, and minimizing disturbances in key habitats will go a long way towards ensuring belted kingfishers remain a iconic sight along North America’s waterways.
