Most Common Bird
1. Hooded Crow
The hooded Crow is often mistaken for the carrion crow (Corvus corone) and has even been regarded as the same species; indeed, these two species may breed to create a hybrid. The hooded Crow is commonly found in woodlands, farmlands, and suburban areas. They can usually be seen in pairs or small groups, looking to find decaying meat, grain, and other protein.
2. Great Tit
Great Tit is a small and plump bird, with a thick black line running through its bright yellow face. It is a common sight in gardens, woodlands, and parks. It is often seen foraging for food in an acrobatic way. Well known for its intelligence, it has been observed using tools, solving problems, and even counting up to five. 
3. Mallard
The mallard is the most abundant duck species in the world, and the ancestor of all domestic ducks. Only the female can produce the distinctive "quack" sound. When the female lays eggs, the male abandons its mate, while the protective mother stays with the ducklings for a long time. This migratory species inhabits shallow waters and it's one of the most popular game birds.
4. Common Chaffinch
The common Chaffinch has a varied diet, mainly feeding on seeds and berries, but also eating insects, allowing it to thrive in different habitats. The Common Chaffinch is also known for its melodic song, with the males being particularly vocal during the breeding season. Their songs can often be heard in the spring and early summer.
5. Eurasian Magpie
The eurasian Magpie is a striking and intelligent bird known for its black and white plumage and long tail. It is highly adaptable, found in a variety of habitats, and known for its intelligence, similar to that of great apes. It is omnivorous, eating both insects and fruits, and it has a reputation for being mischievous and thieving.
6. Eurasian Blackbird
Unafraid of humans, the dark-winged eurasian Blackbird has gained a great deal of cultural significance, mentioned in popular nursery rhymes and songs across the world. Elegant and with an appealing song, they can be aggressive when they are in their breeding period.
7. Common Buzzard
The common Buzzard is a medium-sized bird of prey found in many parts of the world. It inhabits a variety of habitats such as forests, grasslands, and mountains. It is an opportunistic hunter, preying on mammals, birds, reptiles, and insects. They also scavenge on carrion. They are often seen soaring on thermal currents, perching on high vantage points, and performing acrobatic maneuvers during courtship.
8. Grey Heron
The grey Heron is a very common species to come across in marine, brackish, and freshwater ecosystems; these habitats must have at least four months of warm weather or else these birds will migrate for new breeding grounds. The grey Heron hunts by wading through shallow waters looking for fish and various invertebrates; their natural diet helps control some aquatic species populations.
9. Mute Swan
The most common inhabitant of urban lakes and one of the heaviest of all flying birds, the mute Swan got its name by being less noisy than other swan species. Although stunningly beautiful and graceful, it is also quite aggressive and territorial. The national bird of Denmark, the mute Swan is famously portrayed in Hans Christian Andersen's fairytale "Ugly Duckling" and Tchaikovsky's ballet "Swan Lake".
10. European Robin
The european Robin is an aggressive bird that is commonly found throughout farmlands, woodlands, and suburban communities. These birds are mainly helpful insectivores for gardeners, but will also eat various seeds and fruits. The european Robin is used on British Christmas cards to represent postmen from the Victorian era who used to wear red waistcoats while delivering holiday cards.
11. House Sparrow
Just as its name implies, the little house Sparrow socializes with humans more than any other bird species. Able to adapt and thrive in almost any habitat, excluding the extremes such as deserts and mountain peaks, this species was once restricted only to North Africa and Eurasia but now is found across the globe. Unfortunately, this opportunistic eater is not completely harmless—it can cause considerable damage to crops.
12. European Starling
The european Starling, a large, hardy songbird, is one of the most commonly seen bird species in North America. Originally from Europe, this species was brought to the U.S. in the 1890s by enthusiasts of William Shakespeare, who had the unique goal of bringing over every single species of bird that was mentioned in Shakespeare's collective works. Unfortunately, the european Starling, being an adaptable, generalist species, spread invasively across the continent, hurting many native species' populations in the process.
13. Eurasian Blue Tit
The eurasian Blue Tit is a small songbird, very common in urban areas such as parks. This songbird has a wide range of calls and songs, but it's also known for its agility and acrobatic skills - it can hang upside down, reaching food that's not accessible to less-skilled birds. When the bird has young, it spends around 17 hours per day in the search of food for the offspring. It's a frequent visitor of bird feeders.
14. Great Cormorant
The great Cormorant is a charismatic bird known for its diving abilities and fishing prowess. It has a glossy black plumage, a long neck, and a hooked beak. It is strong swimmers and divers, capable of reaching depths up to 30 feet to catch fish. It has a unique habit of spreading their wings in the sun to dry them after fishing, helping to maintain their waterproof feathers.
15. Yellow-legged Gull
Yellow-legged Gull is a large seagull that can be found along coastal regions of the Mediterranean Sea and the Atlantic Ocean. It has a distinctive yellow coloration on its legs and beak, giving it its name. It is an opportunistic feeder, and known to be very territorial. Some populations of Yellow-legged Gulls are migratory, traveling long distances to breed during the summer months.
16. Rock Pigeon
The rock Pigeon is a wild ancestor of all domestic and feral pigeons, inhabiting coasts, cliffs, and caves. Pairs nest in rock crevices, often mating for life. They are known for their ability to fly very long distances to return to their homes, navigating using the sun's position and the earth's magnetic fields. Thanks to this ability, pigeons were used as messengers, particularly during World Wars I and II.
17. European Goldfinch
Prized for its brilliantly colored plumage and pleasant, musical song, the european Goldfinch has been often held in captivity, until this activity became illegal in the 1970s. Native to Europe, the species has been introduced to Australia and New Zealand. It's a very sociable bird that likes to feed on seeds and often visits feeders.
18. Common Wood Pigeon
Although primarily found in woods, the common Wood Pigeon is a large and bulky pigeon that is often seen in towns and cities. Those who inhabit urban areas are quite tame, approachable, and comfortable around humans. This pigeon is a popular game bird, particularly during its migration journeys. Its distinctive call can be heard year-round, particularly at dawn. This ground-dwelling bird gathers in large flocks that feed together.
19. Barn Swallow
A familiar sight in rural and semi-open areas, the small barn Swallow can often be spotted by its distinctly graceful flight as it travels low over fields. Seemingly unbothered by having human neighbors, they nest unafraid in barns, garages, beneath bridges or wharves. Interestingly enough, they have come to prefer these locations so much that you are unlikely to spot a nest in a place that is not a human-made structure.
20. Common Chiffchaff
The common Chiffchaff is a small warbler known for its distinctive "chiff-chaff" call. It can be found in woodlands, gardens, and parks throughout Europe and Asia. It feeds on small insects, spiders and other invertebrates, which it catches by gleaning from leaves and branches.
