Mistle Thrush Diet and Size: Feeding Habits, Predators, and Measurements
Mistle Thrushes are fascinating birds recognised for their strong feeding habits and their significant role in their habitats. Their diet not only supports their growth but also contributes to seed dispersal.
In this article, we will look into their size, feeding behaviours, and the predators they encounter. Keep reading to learn more.

The Dietary Habits Of The Mistle Thrush
Let’s take a look at what Mistle Thrushes eat and how they feed their young during different stages of growth.
What Does A Mistle Thrush Eat?
The diet of Mistle Thrushes mainly consists of invertebrates, fruits, and berries. They typically consume slugs, worms, insects, and their larvae.
In the breeding season, they may catch larger prey like slowworms and occasionally young birds from other species to feed their chicks.
They particularly favour berries, such as mistletoe, holly, yew, and rowan. Mistle Thrushes exhibit strong territorial behaviour, fiercely defending trees filled with berries during winter to ensure a steady food supply.
What To Feed A Baby Mistle Thrush?
Adult Mistle Thrushes mainly provide their chicks with a diet rich in invertebrates. This includes worms, slugs, insects, and their larvae which supply the necessary nutrients that support the rapid growth and development of the chicks.
As the chicks mature, they also begin to eat fruits and berries, which adults commonly consume. The parents actively forage, and are often seen hopping on the ground or searching low foliage to collect food items for their nestlings.
Breeding Habits Of Mistle Thrushes
Raising two to three broods annually is common for Mistle Thrushes, usually starting the breeding season from February to May.
The female Mistle Thrush is solely responsible for nest building, which results in a sturdy, cup-shaped structure often found in the fork of a tree. The nest is made from a combination of twigs, roots, leaves, and grass, combined together with mud.
Clutches typically contain 3 to 5 eggs, pale blue colour and often marked with reddish-brown speckles. The incubation period lasts about 12 to 15 days, primarily carried out by the female. Once hatched, the chicks fledge roughly 14 to 16 days later.
Do Mistle Thrushes Mate For Life?
Mistle Thrushes don’t mate for life. Instead, they create seasonal monogamous bonds, which means they pair with a mate for the breeding season only.
During this time, they might successfully raise as many as three broods together. At the start of every breeding season, fresh pairings can form, indicating that these birds do not stay with the same partner for life.
The Size & Weight Of Mistle Thrushes
In this section, we’ll be looking at the size and weight of Mistle Thrushes, covering their weight range and overall body size.
How Much Does A Mistle Thrush Weigh?
The average weight of a Mistle Thrush is between 100 and 150 grams, making them one of the heaviest thrush species found in Europe.
How Big Is A Mistle Thrush?
The Mistle Thrush is one of the larger birds in the thrush family, known for its sturdy build. This species can grow to about 27 centimetres in length and has a wingspan that falls between 42 and 48 centimetres. This makes it one of the largest thrushes found not only in the UK but across Europe as well.
Are Mistle Thrushes Under Threat?
Currently, Mistle Thrushes are classified as “Least Concern” by the IUCN, indicating they are not currently seen as globally threatened thanks to their wide range and large population. However, they are facing declines in some regional populations. Changes in agricultural practices are thought to be impacting the habitats and food sources available.
For instance, in the UK, the Mistle Thrush is listed as “Red” under the Birds of Conservation Concern, reflecting its status as a species in urgent need of conservation due to marked population reductions in recent years.
What Eats A Mistle Thrush?
Mistle Thrushes face threats from various predators, including sparrowhawks, which are agile hunters capable of capturing these birds in mid-air.
Foxes also present a danger, as they often raid nests for eggs and young birds, particularly those built low to the ground. Additionally, domestic and feral cats are threats, especially in urban settings where they may hunt both fledglings and adult Mistle Thrushes.
Despite these dangers, Mistle Thrushes are very aggressive in guarding their nests, often confronting larger predators with a boldness that reveals their strong parental instincts.
Where Can I See Mistle Thrushes In The UK?
In the UK, Mistle Thrushes are commonly observed, thriving in numerous habitats such as rural areas, parks, woodlands, and gardens. They are particularly noticeable in places with an abundance of berry-laden trees and shrubs, which they actively defend during the winter season.
You can find these robust songbirds in open woodlands often foraging on the ground or singing from high perches. Areas with mixed and deciduous woods are especially favourable due to the rich undergrowth and berries that provide both food and nesting opportunities.
Hazeley Heath in Hartley Wintney (Hampshire) is an excellent spot for observing Mistle Thrushes, due to its rich heathland habitat that supports a wide variety of bird species.
