Fieldfare Diet and Size: Feeding Habits, Predators, and Measurements
Fieldfares are medium-sized thrushes, with a diet that changes with the seasons. This, along with their size, plays a key role in migration by allowing them to gather the energy needed to travel great distances.
In this article, we’ll learn about the Fieldfare’s feeding habits, their size and weight, and how these factors influence their ability to survive and migrate. Continue reading to learn more.

The Dietary Habits Of The Fieldfare
Let’s look at what Fieldfares eat throughout the year and what foods are important for their chicks.
What Does A Fieldfare Eat?
Fieldfares adjust their diet according to the seasons. In summer, they mainly eat invertebrates like snails, earthworms, and insects.
As winter approaches, their diet changes to plant-based foods, which include berries like juniper, hawthorn, rowan, as well as fallen fruits, and seeds.
What To Feed A Baby Fieldfare?
The diet of Fieldfare chicks is rich in invertebrates, particularly in their early life. Earthworms, snails, and various insects make up a large part of their diet, providing the necessary nutrition for growth.
As the young birds mature, the adult Fieldfares begin introducing more plant-based foods, including berries and fallen fruits. This shift helps the fledglings adjust to the foraging they will do after leaving the nest.
Breeding Habits Of Fieldfares
The breeding season for Fieldfares starts in March and runs through to June. For breeding, they favour habitats like woodland edges, open forests, and mixed woodlands, which provide nesting sites and open spaces for foraging.
These birds build their nests in trees or large shrubs, using materials like grass and twigs, and lining them with mud and fine grass for insulation.
A typical clutch consists of 5 to 7 eggs, which are blue-green with reddish or brown spots. The female incubates them for around 14 days. Once hatched, the chicks fledge in approximately 2 weeks, although they remain dependent on their parents for a few weeks more.
Do Fieldfares Mate For Life?
Unlike some other species, Fieldfares do not mate for life. They form new pairs each breeding season, and once the season is over, the bond ends.
When the next spring arrives, they may select different partners. This type of seasonal pairing, rather than long-term monogamy, is typical for Fieldfares.
The Size & Weight Of Fieldfares
Let’s look at the size and weight of Fieldfares, their typical weight, and how large they tend to be.
How Much Does A Fieldfare Weigh?
Between 80 and 130 grams is the typical weight of Fieldfares. This weight is essential for their long migrations, as it affects their energy levels and overall health.
How Big Is A Fieldfare?
Fieldfares are medium-sized thrushes, usually about 25 cm long. Their wingspan ranges from 39 to 42 cm, making them one of the larger birds in the thrush family.
These measurements mean that Fieldfares are a bit smaller than the Mistle Thrush but larger than many garden birds like the Blackbird.
Are Fieldfares Under Threat?
The IUCN currently lists Fieldfares as “Least Concern” because of their stable and large population, which is thought to range between 15 and 40 million individuals globally.
In the UK, however, they are classed as a Red List species under the Birds of Conservation Concern due to their limited numbers as breeders and regional declines, mainly caused by habitat loss.
What Eats A Fieldfare?
As medium-sized birds, Fieldfares face several natural predators. Birds of prey, such as Sparrowhawks and Goshawks, can capture adult Fieldfares.
Additionally, ground predators like cats and foxes pose a threat, particularly to birds that forage or rest on the ground. Their nests are also at risk, as Crows and Magpies can consume eggs and chicks.
To reduce these risks, Fieldfares often nest in small colonies. This strategy allows them to take advantage of collective vigilance and mobbing behaviour, helping them keep potential predators away.
Where Can I See Fieldfares In The UK?
The UK sees Fieldfares during the winter months, where they can be found in areas abundant in food and shelter. Bodenham Lake in Herefordshire is a prime location, famous for its historic orchards and fallen apples that bring large flocks of fieldfares in autumn and winter.
The Sturts Nature Reserves in Herefordshire, offering hedgerows and orchards filled with berries and fruit, provide another excellent environment. Common Hill in Fownhope, perched on a ridge with its old fruit trees, also makes a great site for observing these birds as they feed and socialise.
Near Hereford, Hampton Park Road Meadow stands out with a mix of mature and younger fruit trees, as well as mistletoe-covered branches that attract fieldfares during colder months.
Pool Ellocks in Goodrich, with its heritage orchard dating back to 1890, supplies cider apples and perry pears, making it another excellent place for fieldfare sightings.

Frequently Asked Questions
A Fieldfare bird’s diet varies with the seasons. In summer, they primarily consume invertebrates such as snails, earthworms, and insects, while in winter, their diet shifts to plant-based foods, including berries like juniper, hawthorn, rowan, fallen fruits, and seeds.
The main difference between a Mistle Thrush and a Fieldfare is size and appearance. Fieldfares are medium-sized thrushes that are a bit smaller than Mistle Thrushes but larger than many other garden birds like the Blackbird. Additionally, Fieldfares change partners each breeding season, whereas Mistle Thrushes may maintain longer-term pair bonds.
A Fieldfare is a medium-sized thrush, typically about 25 cm long with a wingspan ranging from 39 to 42 cm. They are considered one of the larger birds within the thrush family.
The status of Fieldfares is listed as “Least Concern” by the IUCN due to their stable and large global population. However, in the UK, they are classified as a Red List species under the Birds of Conservation Concern because of their limited numbers as breeders and regional declines, primarily caused by habitat loss.
