Dotterel Diet and Size: Feeding Habits, Predators, and Measurements
Dotterels are migratory birds that travel over great distances each year. Their diet is crucial for supporting these long travels, and their size enables them to cover large areas without tiring easily.
In this article, we will look into their diet, feeding habits, predators, and how their size and weight affect their movement patterns. Keep reading to learn more.

The Dietary Habits Of The Dotterel
Let’s take a look at what a Dotterel eats and how they feed their chicks a diet that helps them grow.
What Does A Dotterel Eat?
The Dotterel feeds on insects like ants, beetles, and grasshoppers, hunting them with a distinct run-and-pause technique. It also eats other invertebrates such as worms, snails, and shellfish. These provide important nutrition, especially during the breeding season when the bird needs more energy for mating and raising its young.
What To Feed A Baby Dotterel?
Chicks of adult Dotterels are fed a variety of insects and small invertebrates. This includes moth and butterfly larvae, ants, crickets, grasshoppers, and spiders. They are also fed snails, worms, and sometimes plant-based items like leaves, flowers, seeds, and berries.
Breeding Habits Of Dotterels
Unlike most bird species, the female Dotterel is more colourful and larger than the male, taking on a dominant role during the breeding season. She performs courtship displays to attract males and may mate with multiple partners, laying several clutches of eggs to take full advantage of the short breeding seasons in their Arctic and alpine habitats.
The male assumes the main responsibility for incubating the eggs and looking after the chicks once they hatch. This includes guarding the female during egg formation to ensure paternity, then taking on most of the nurturing duties after the eggs are laid. This role reversal allows females to maximise their reproductive success by focusing on egg production and mating.
The breeding grounds of these birds are often found in cold, windswept areas like the Arctic tundra or mountain plateaus. These regions have flat, open terrain with minimal vegetation, often scattered with rocks and boulders.
Do Dotterels Mate For Life?
Dotterels do not mate for life. After laying their eggs, females typically leave the responsibility of incubation and raising the chicks to the males. In some cases, they may look for other mating opportunities. This behaviour, known as serial polyandry, where females may have multiple mates, shows that they do not form lifelong pair bonds.
The Size & Weight Of Dotterels
Let’s take a look at how much a Dotterel weighs and the measurements that define their shape and movement.
How Much Does A Dotterel Weigh?
Typically, a Dotterel weighs between 90 and 145 grams. This makes them relatively light, which is a usual trait for birds in the plover family, allowing them to be agile and travel with ease during their migrations.
How Big Is A Dotterel?
A medium-sized wader, the Dotterel usually measures between 20 and 22 centimetres in length. With a wingspan of 57 to 64 centimetres, it helps to navigate the high altitudes and long distances of its migratory path.
Are Dotterels Under Threat?
Globally, the Dotterel is listed as “Least Concern” by the International Union for Conservation of Nature (IUCN). In the UK, however, the species is classified as “Red” due to a sharp decline in numbers, especially in Scotland.
The breeding population of males has dropped significantly, putting the Dotterel high on the list of birds in need of urgent conservation efforts in the UK.
What Eats A Dotterel?
During the nesting season, birds like the Common Raven and Common Gull can become a danger to Dotterels, especially when they get too close to the nest or chicks. To protect their young, Dotterels use distraction techniques such as “tail-flagging.” This includes running away from the nest to catch the predator’s focus, then halting suddenly and adopting specific postures to mislead the predator about the nest’s or chicks’ actual location.
Where Can I See Dotterels In The UK?
Cairngorms National Park in Scotland is a key location for breeding Dotterels, with its vast montane habitats attracting the birds from April to October.
Migration is often witnessed at Pendle Hill in Lancashire, with dotterels particularly visible in late April and early May. Another great spot is Ilkley Moor near Bradford, where the birds are frequently seen around the Twelve Apostles stone circle during spring migration.
Beyond the Cairngorms, the Scottish Highlands also offer large areas where these birds can be observed, making them perfect for birdwatchers looking to see dotterels in the wild.

Frequently Asked Questions
The threats to the Dotterel include predation by birds like the Common Raven and Mew Gull, especially during the nesting season. Additionally, a significant decline in the breeding population, particularly of males in Scotland, has raised concerns about their survival.
