Cattle Egret Diet and Size: Feeding Habits, Predators, and Measurements
Cattle Egrets (Bubulcus ibis) are distinctive birds, slightly smaller than their close relatives the Little Egret. They have yellow beaks and yellow or grey legs, buff plumage (which is particularly prominent during the breeding season) and predominantly white feathers.
Males and females look very similar with males being slightly larger than females. These heron-like birds are accomplished night flyers and in areas where they migrate, they often fly at night.
In this article, we’ll take a close look at the dietary habits, breeding habits, size and weight of these fascinating birds. As well as their conservation status and what predators they face. Keep reading to find out more.

The Dietary Habits Of The Cattle Egret
Cattle Egrets have a varied diet mainly consisting of small animals and insects. They are often seen around livestock like sheep or cattle (from where they get their name) eating the insects and vertebrates stirred up by the hooves of the livestock.
The birds swoop in to catch the insects, making it easier to find food without expending too much energy. This behaviour is beneficial not just for the egrets but also for the livestock, as the birds help reduce the number of biting insects.
What Does A Cattle Egret Eat?
Cattle Egrets’ diet is mainly made up from insects including grasshoppers, crickets, beetles, flies, dragonflies, moths and other flying insects.
They also eat small amphibians like frogs, reptiles including lizards and snakes and even small mammals like mice and voles. If they’re foraging near water, they will also eat fish.
Cattle Egrets are opportunistic and adapt their diet based on availability. For example, they will feed on earthworms, spiders, and other small creatures when insect populations are low.
What To Feed A Baby Cattle Egret?
Parents feed their chicks primarily by regurgitating partially digested food. This usually consists of the same insects and small animals the adults eat.
They tend to feed their chicks nutrient rich insects like grasshoppers and crickets which are easy for the chicks to digest. As the chicks grow, they will start to be fed slightly larger prey including small frogs and lizards and even small mammals.
Breeding Habits Of Cattle Egrets
Cattle Egrets have fascinating breeding habits including distinct courtship rituals to attract mates. During the breeding season, Cattle Egrets develop bright orange-buff plumage on their head, chest, and back, along with pinkish legs and a reddish beak. This breeding plumage is more vibrant and prominent in males.
Males will perform a behaviour known as “bill clappering,” where they rapidly open and close their beak, making a distinctive sound. This is often accompanied by bowing movements to display their breeding plumage.
They will also offer the female twigs as part of the courtship display in an effort to demonstrate their ability to provide adequate nesting materials. Males will also perform short aerial displays around the nesting site, often flying with exaggerated wing beats to draw attention to themselves.
Do Cattle Egrets Mate For Life?
Although Cattle Egrets don’t mate for life, they are seasonally monogamous. Which means they form a pair bond that will last until the chicks are raised.
The Size & Weight Of Cattle Egrets
Male and female Cattle Egrets tend to be around the same size with the males being ever so slightly larger. However, the difference is not so great that it can be used to differentiate between the sexes in the field.
How Much Does A Cattle Egret Weigh?
The average weight of an adult Cattle Egret is somewhere in the region of 300 to 400 grams. Males tend to be slightly heavier than females.
The weight of Cattle Egrets can vary at different times of the year and is very much dependent on food availability.
How Big Is A Cattle Egret?
The average length of an adult Cattle Egret is around 45 to 50 centimetres with a wingspan of between 82 to 95 centimetres. These dimensions make the Cattle Egret slightly smaller than their close relative the Little Egret.
Are Cattle Egrets Under Threat?
Cattle Egrets are currently classified as Least Concern on the International Union for Conservation of Nature (IUCN) Red List. This means they are not considered to be at significant risk of extinction at this present time.
Their populations are generally stable or even increasing in many parts of the world due to their adaptability to a wide range of habitats, including agricultural and urban environments.
Having said that, although Cattle Egrets are not currently under serious threat, they do face certain challenges like; habitat loss due to wetland drainage, agricultural expansion and urban development, pesticides and other agricultural chemicals can cause poisoning and loss of food sources.
What Eats A Cattle Egret?
Cattle Egrets have a range of natural predators, especially targeting their eggs, chicks, and sometimes adults, these include; Large raptors like eagles and owls that will take adult Cattle Egrets as will foxes, raccoons and cats both domestic and wild.
Whilst chicks and eggs are under threat from snakes, large lizards, birds of prey (like eagles, hawks and owls), Crows and Ravens, rats, foxes, raccoons and other large mammals like weasels and stoats.
In some parts of the world, Cattle Egrets are hunted for food or sport, though this is not widespread enough to cause significant population declines.
In general terms, Cattle Egrets are a conservation success story, demonstrating resilience in the face of environmental changes and expanding their range globally.
Where Can I See Cattle Egrets In The UK?
Cattle Egrets have become an increasingly common sight in the UK, particularly in recent years due to their expanding range. The best places to spot Cattle Egrets in the UK include;
- Somerset Levels and Moors (Southwest England)
- Ham Wall RSPB Reserve and Shapwick Heath National Nature Reserve (Southwest England)
- Dorset (South Coast)
- South Devon
- East Anglia (Norfolk and Suffolk)
- Newport Wetlands Reserve and the Gwent Levels (South Wales)
While Cattle Egrets can be seen year-round, they are more commonly spotted in the UK during the autumn and winter months (from late summer into early spring), often joining flocks of other egret species like Little Egrets.
They are more likely to be seen in wet meadows, marshes, and grazing fields, especially following heavy rainfall when the ground is softer, making it easier for them to forage.
True to their name, Cattle Egrets are often found around grazing cattle, sheep, and horses, where they feed on insects stirred up by the animals.

Frequently Asked Questions
Yes, there are Cattle Egrets in the UK. They are to be found in close proximity to livestock (cattle, sheep and horses) where they feed on insects exposed in the ground by the hooves of the grazing livestock.
You can find Cattle Egrets in places like the Somerset Levels, Dorset, South Devon, East Anglia, and the Severn Estuary.
The role of the Cattle Egret is to remove ticks and fleas from the livestock they live amongst. Cattle Egrets also benefit from the exposure of insects as the livestock move the soil with their hooves.
Cattle Egrets mainly eat insects, such as grasshoppers, crickets, and beetles, but they also feed on small animals like frogs and lizards.
They are called Cattle Egrets because they are often seen following cattle and other large animals to catch insects stirred up by their movement.
