Herons are a species of large water birds with long S-shaped necks and long, skinny legs, in the family Ardeidae. There are many types of Heron, including the Great Blue, the Great White, the Little Blue, and the Goliath Heron.
However, some of the birds in the Ardeidae family are known as bitterns or egrets, so there is no biological distinction between these two water-dwelling birds.
Egrets are actually just a type of Heron, though there are a few visual and measurable differences between these two birds.
Comparing Egrets vs Herons
In general, egrets are smaller, paler birds, with darker legs and sometimes darker beaks. There are several sizes of both these birds, but the easiest comparison of the birds can be made between the Great Egret and the Great Blue Heron.
Great egrets tend to be a little smaller than the white-phase great blue heron, but one of the key differences to look for when telling apart these two species is that great regrets have dark legs, and the herons have much lighter color legs. Herons may also have a slightly heavier beak, although, that detail an be overlooked.

The 5 Key Differences Between Herons and Egrets
Herons vs Egrets: Head and face
An Egret typically has a very sharp black or yellow bill, designed for catching fish. During breeding the Great Egret gets green patches around its eyes. Herons have very similar beaks, though they are larger and typically always yellowish-orange. They usually have plumes on their faces.
Herons vs Egrets: Wings
Herons have broad, round wings which are quite large compared to their bodies. Egrets have much smaller wings, though they are still rounded and somewhat broad.
Herons vs Egrets: Coloring and Plumage
Herons are mostly blue and gray, though some species are white, and their legs and beaks are usually pale. Egrets are usually white, with black legs and sometimes black bills.
Egrets only have plumes on their back during mating season. Herons have plumes on their heads, faces, and chests year round, giving them a somewhat furry appearance.
Herons vs Egrets: Size (Height & Weight)
One average, Herons are somewhat taller than Egrets, particularly when they both have their necks extended. They are also heavier. Larger types of herons reach about twice the weight of the largest Egrets.
Herons vs Egrets: Legs
Herons tend to have legs that are yellow to orange, while egrets usually have solid black legs.
Bonus: Which Birds are the Tallest in the World?
Both herons and egrets have long, slender legs that give them a “leg-up” in terms of height. While they both rank among the tallest birds around, there are some birds that outmatch them when it comes to height and weight combined. Let’s take a look at the top 5 largest birds in the world.
Ostrich
The ostrich takes the number one spot as the largest bird on the planet. It stands at an average of 9 feet tall and weighs from 220-350 pounds. These towering flightless birds are native to Africa.
Emu
The emu, native to Australia, resembles the ostrich as a close second in height and weight, as well as being flightless. Its height ranges from 5-6.5 feet, while it weighs in from 80-130 pounds on average.
Cassowary
Standing from 5.8 to 6.6 feet tall and weighing 110-130 pounds, the cassowary is another flightless bird that ranks high in the “largest” category. It hails from New Guinea and surrounding islands.
Rhea
The rhea is a South American bird that’s related to the ostrich. While not as tall and large as its cousin, the rhea can grow from 5-6 feet tall and weigh from 66-88 pounds.
Kori Bustard
One of the heaviest birds capable of flight in the world is the African Kori bustard, which averages 5 feet in height and 40 pounds in weight.
