A tribute to the kingfishers of KELÁ_EKE Kingfisher Forest

Belted kingfishers are the only species of kingfisher found in Canada. Living at the interface between land and water, these iconic blue birds symbolize the interconnectedness of all ecosystems surrounding the Salish Sea.

Near the top of the cutbank that slopes down to the shoreline of KELÁ_EKE Kingfisher Forest are several excavated holes burrowed into the bank. These burrows can extend anywhere from 1.5 – 4.5 m into vertical, unvegetated bluffs, sandbanks, or road cuts like the one shown in the photo below. Their engineer is a member of a unique, diverse and colourful family of birds: the kingfishers. Part of a larger and even more diverse order that includes birds like kookaburras, bee-eaters, and rollers, kingfishers and their relatives reach their greatest species diversity in Australia and southeast Asia. Of 87 species of kingfisher worldwide, only six are found in the western hemisphere, and only one—the belted kingfisher (Megaceryle alcyon)—is found in Canada.

Belted kingfisher: A natural history

Some kingfisher species are terrestrial, living in forests or savannahs and feeding on insects, amphibians, reptiles, young birds, and small mammals. Our familiar belted kingfisher, in comparison, is part of the subfamily of “fishing kingfishers” (Subfamily Alcedininae), which inhabit streams, ponds, lakes, and marine shores and feed mostly on fish, amphibians, and aquatic invertebrates. Belted kingfishers are migratory through most of their range in Canada, because they rely on open water for foraging; in contrast, on the mild south coast of British Columbia, we are fortunate to enjoy kingfishers and their distinctive rattling calls along our shores—including the shoreline at KELÁ_EKE Kingfisher Forest—year-round.

The bright ornamental plumage displayed by both male and female belted kingfishers is a trademark characteristic of this avian family. Females appear more ornamented than males because they display a chestnut breast band in addition to the bright blue back, head, and neck band common to both sexes; however, spectral analysis has shown that both the blue and white feathers of male kingfishers are actually brighter than females (i.e. they reflect more light). The prominent bill of the kingfisher has slightly serrated edges (called “tomial serrations”) to assist them in gripping slippery fish. Such interesting birds would not be complete without also having interesting feet: referred to as “syndactyl”, the forward-facing toes of kingfishers and their relatives are fused. For kingfishers, this may allow the feet to function as a “shovel” to push earth out of the burrow during excavation, although most of burrow excavation is accomplished using the long and robust bill.

Kingfisher pairs defend territories varying in size depending on habitat, but territories typically extend 1-5 km along a shoreline. Both sexes excavate the nest burrow and incubate the clutch of 5-7 eggs. Hatchling kingfishers are altricial, meaning they are blind and naked. This development pattern is common in songbirds, but is rare in other bird families. As with songbirds, development of kingfisher young is rapid and young leave the nest after around 24 days. These fledged young must then learn to fish; parents assist with this process by bashing small fish against a tree limb or rock to slightly stun them, then dropping them back into the water for the young birds to retrieve. After mastering these impaired prey, young kingfishers move on to hunting fully mobile fish, amphibians, and invertebrates, finally achieving independence 1-2 weeks after fledging.

Although belted kingfishers are widespread, their numbers have been declining across Canada and in British Columbia. Among the possible reasons for these declines are reduced habitat quality and/or abundance (wetland, pond, and stream disturbance and loss); fewer available nest sites; environmental contaminants; and human disturbance. Human-built landscapes such as roadcuts and gravel pits provide nesting habitat that is otherwise limited to high, vertical earthen banks along streams and shores, and degradation of these natural nesting substrates due to increased flooding, erosion, grazing in riparian areas, and other human disturbances may contribute to population declines.

Due to their reliance on fish and other aquatic prey, belted kingfishers are important ecological monitors of contamination in aquatic systems, because they bioaccumulate environmental contaminants like mercury in their tissues. Effects of mercury on plumage colour and some measures of reproduction like brood sex ratios have been reported, and while other physiological effects have not been well documented, impacts of environmental contaminants on health, survival, and reproduction in kingfishers are likely significant.

As top predators in aquatic food webs, birds like belted kingfishers (not unlike wolves in terrestrial and coastal systems in North America) have disproportionate effects on abundance, foraging behaviour, habitat use, and growth rates of species at lower trophic levels. Kingfishers also serve as primary burrow excavators in riparian systems, with other species such as bank and rough-winged swallows using their burrows for nesting in subsequent years.

In KELÁ_EKE Kingfisher Forest, belted kingfishers forage along the marine shoreline as well as in the freshwater aquatic habitat of Gardom Pond, and their nest burrows line the cutbank near the shore. More than any other single species, kingfishers knit all the diverse habitats on this land together through their life cycle, holding forest, ocean, and wetland on their brilliant blue wings.

How you can help

KELÁ_EKE Kingfisher Forest exists at the interface between land and sea. It provides ideal habitat for belted kingfishers and myriad other bird, amphibian, and other wildlife species. The Pender Islands Conservancy and Raincoast Conservation Foundation need your help to reach our financial target of $2.1 million. Your support will aid in the permanent protection of this collection of forest, wetland, and foreshore habitats. You can track our progress and learn more about our land protection work by visiting our campaign page.
