Some of the most common birds of the world that aren’t easy to spot have yellow eyes.
Multiple species of owls have yellow eyes. Their nocturnal hunting habits and secretive lives make them difficult to spot.
While some types of birds with yellow eyes are easy to spot since they can live in urban areas, many live outside urban areas in savannahs, mixed woodlands, coniferous woodlands, coastal areas, or on remote islands of the world.
Eagles also come with yellow eyes across multiple species. These birds are also difficult to spot, especially since many only look for prey in rivers or open seas.
Some species of ducks also have yellow eyes of different nuances. Diving ducks that are ready to go deep into the water for fish often come with yellow eyes either throughout the year or in the breeding period.
Yellow eyes don’t prove a bird species has better vision. It can be an adaptation but many species only truly have yellow eyes once they reach adulthood.
Bird iris colors can change over time. Juveniles are rarely born with bright eyes and only get yellow irises once they’re ready to move out on their own.
The following species of birds are known for having different shades of yellow eyes and may even be spotted in different regions around the world.
1. Hooded Merganser
Hooded Mergansers (Lophodytes cucullatus) are common North American ducks with yellow eyes.
There’s a clear difference to which Hooded Mergansers have yellow eyes as only males have them.
The young male duck initially has pale eyes which become yellow as it reaches its breeding age. Females have dark brown eyes and even have different plumage.
Yellow nuances are only seen in the eyes of males and not in their plumage. In turn, females have a yellow beak while males have a black beak.
Males also turn black and white on the back and wings going into the breeding season.
Distribution – Western Canada, Southern Canada, Eastern United States, Western United States
2. Great-tailed Grackle
Yellow eyes are the only bright section on the dark-looking Great-tailed Grackle (Quiscalus mexicanus).
Birds of the species are sexually dimorphic, with considerable differences between males and females.
While both males and females have yellow eyes, males have a black color with blue-purple metallic undertones.
Some areas such as the head are black and purple while its wings and belly are black with blue nuances.
Females are mostly brown. They show various shades of brown but also have yellow eyes.
Juveniles of the species don’t have yellow eyes.
Distribution – Central and Southern United States, Mexico, Guatemala, Costa Rica, Panama, Venezuela, Ecuador
3. Ring-necked Duck
Much of the Ring-necked Duck’s (Aythya collaris) appearance changes going into the breeding season.
Males are the ones with the yellow eyes, but only in the breeding period. Their eyes are orange-yellow before brightening up to vivid yellow in the breeding period.
Females have dark brown eyes but have different traits such as the capacity to make noises.
Males aren’t named after their bright eyes but after the cinnamon-brown neckband spotted in the breeding season.
A black neck base color means this neckband might not be easily spotted.
Distribution – Northern Canada, Eastern Canada, Central Canada, United States, Mexico, Cuba, Panama
4. Lesser Scaup
A migratory species of diving ducks in North America, Lesser Scaups (Aythya affinis) are differentiated by their appearance when it comes to males and females.
The male has bright yellow eyes while female ducks have bright brown eyes.
Males are also brighter while females are dominated by brown plumage.
Lesser Scaups are also known for their bright blue bills only seen on males. This is what inspires their name Little Bluebills, despite reaching sizes of up to 19 inches.
These diving ducks live in some of the coolest areas of North America, including Alaska. They migrate to California or The Gulf of Mexico to overwinter.
Distribution – United States, Canada, Mexico
5. Common Goldeneye
Golden yellow eyes inspire the name of these ducks (Bucephala clangula).
Both males and females show bright yellow eyes which are contrasted by a dark head but which has different colors from males to females.
Male Common Goldeneyes have a dark head with a dark green sheen. This dark head is in stark contrast with their yellow eyes and white patches on the face.
Yellow-eyed females have a brown head but they have a yellow-orange feed.
Plumage differences are further seen between the sexes. Males are black and white while females are mostly gray and white.
Boreal forests are the ideal habitats for these otherwise aggressive ducks,
Distribution – Canada, United States, Russia, China
6. Cattle Egret
A species of the tropics and subtropics, Cattle Egrets (Bubulcus ibis) are named after they tend to rest on cattle.
These types of birds change their appearance going into the breeding season.
Yellow eyes are specific to the species. The yellow nuance becomes orange or orange-red in the breeding season.
Its plumage also changes from white to white and orange as the breeding period begins soon after these birds return from their overwintering sights (in the case of migrating populations).
These types of birds are found on all continents. They show a year-round presence in South America, Africa, and Southern Asia.
Distribution – North America, Central America, South America, Western Europe, Africa, Southeast Asia, Australia
A North American Species, Redheads (Aythya americana) are named after the vivid color of the male ducks.

Snowy Owls (Bubo scandiacus) are the only types of owls to be mostly white, as a result of their Northern Arctic habitats.
These types of owls also have bright yellow eyes, a characteristic which has some exceptions such as hybrids with orange eyes.
These types of predators have white and black plumage and are found across North America, Northern Europe, and Northern Asia.
A short breeding season means these birds might even migrate soon to breed. They tend to seek out new breeding locations as Snowy Owls aren’t tied to their native areas for breeding.

Growing up to a size of 7.9 inches, the small own uses old holes and cavities as its nests. It can repurpose woodpeckers nesting sites as its nests.
The 3 subspecies of Whiskered Screech-Owls always build their nests on trees, at a considerable height above the ground.
Cavities are their nests and they place small clusters of eggs here. They also hide and look for prey from these old tree cavities.

Yellow eyes are specific to Ospreys (Pandion haliaetus), a species of hawks found around the world.
This species is mostly found around rivers and water sources. It is even nicknamed The River Hawk as it rarely ventures away from water.
Its diet is the main reason for its presence next to rivers as Ospreys feed on fish.
Raptors or birds of prey are generally good at catching small prey. However, Ospreys are also very good at spreading out their habitat for food.
These birds are known as very good divers. While they don’t catch fish every time they dive, they still manage to have a very high success diving rate catching at least 1 fish for every 5 dives.
They represent one of the most common predatory birds in the world.
Manmade structures are some of the best places to find these birds. They tend to build nests on high vantage points such as on buildings, poles, or towers.
