Start birdwatching. Bird watching is a practical subfield of ornithology, which studies birds. Birds are typically observed through binoculars or a spotting scope from a distance to identify their species, age, and sex. Digiscoping is the term for using a digital camera to take notes. Additionally, birds can only be recognized by their song or other vocalizations. The identification of a bird through its remnants, such as nests, feathers, and pellets, is typically the domain of specialists.

This is how you start birdwatching.

Birdwatchers require experience in bird identification as well as extensive knowledge of bird biology. One can learn the basics by reading one of the many books on bird identification, listening to bird call recordings, and taking guided tours with seasoned birdwatchers. Associations for nature conservation typically organize these. Additionally, ecotourism businesses provide birding excursions led by knowledgeable ornithologists and landscape photographers.

You can find plenty of bird watching information on this scientific birdwatching site where they explain information about birdwatching in the United States. The learning of identification traits is further aided by compilations of birds that are presented in pictures and sound for PCs and DVD players. In recent years, bird watching as a hobby has grown in popularity. It is also known as “birding” or “bird watching.” Men and women are both out and about watching birds. Some meticulously maintain lists of the various bird species they have seen or heard, known as species lists. Others enjoy watching birds for entertainment. [2] In recent years, book authors have reported on their bird watching experiences in both biologically accurate and emotionally gratifying ways.

Birding data collection is also known as mapping, population assessment, or monitoring when it is done for scientific or conservation reasons. There are numerous ways for amateur observers to get involved in this.

Twitching, also known as spotting, is the active form of birdwatching.

Phoebe Snetsinger was the most successful twitcher in the world, recording 8400 different bird species between 1965 and the time of her death in 1999, earning her a spot in the Guinness Book of World Records. With roughly 9600 bird species, Jonathan Hornbuckle (1943-2018) holds the record as of 2017.

Bird watching photography

Photography has always been a part of bird watching, but until the use of digital cameras in conjunction with portable telescopes gave rise to the technique known as digiscoping, which has facilitated the expansion of this hobby to many more people, it was relegated to the background due to the cost of good cameras and lenses. One of the joys of nature photography is being able to feel the same way a hunter feels while looking for his prey, with the difference being that the photographer “captures” a moment in a bird’s life rather than killing it.

The sense of sight of birds is generally very well developed. At a distance of several meters, birds can detect insects the size of millimeters. The small rabbit in the grass, which hops several tens of meters below the birds of prey, is hit unerringly. And this despite the fact that the target object had to be aimed at in mid-flight. Compared to mammals, birds have an above-average sense of sight. By the way, this is in contrast to the sense of smell, where mammals are ahead.

The sense of sight is essential for survival
Birds register their food primarily with their sense of sight. They detect small prey such as hares or field hamsters from a great distance. But even the tiniest insects and even their eggs do not remain hidden from the hungry bird’s eye. For themselves or their young, birds of prey, songbirds and co. spot their prey.

But birds do not only depend on their good eyes to find food. Especially in the case of birds, which often become prey themselves, the eyes play an important role in the fight for survival. Because only those who recognize their enemies quickly can flee in time.
Nocturnal birds, such as owls and screech owls, have excellent night vision. Many insectivorous birds, such as swallows and swifts, have the ability to see insects in rapid flight and scoop them up. To us, this is an incredible feat. Tits are more of the gatherers. Nevertheless, these birds also have a keen sense of sight. For example, they spot tiny insect eggs hidden in small branch crevices, which they feed on.

Birds’ eyes are larger relative to body size than those of mammals. Depending on the ecology, bird eyes have numerous special adaptations. For example, the anatomy of birds enhances their vision:

What’s the head bob for?
Back and forth, back and forth. When walking, the head of many birds appears to be in constant motion. But in fact, the opposite is true. While the body continues to move forward, the head remains still for a moment. Thus, in this moment of stillness, the eyes can better detect moving objects in their environment.

The 360° all-round view
Bird species that are primarily prey for predators have their eyes on the side of their head. This allows them to see in almost any direction and locate their enemies more quickly. However, because the fields of view of each eye almost do not overlap, their ability to see spatially is significantly limited.

Mobility in the neck
Unlike prey such as pigeons or chickens, which benefit from 360° vision, owls have their eyes side by side at the front of their heads. Their spatial vision is very strong. To ensure that they can also see in any direction without difficulty, they have the ability to rotate their head 270°. For example, they can look to the right even though they have their necks turned to the left.

Binoculars in the eye
Birds of prey that need to track down their prey over very long distances (e.g., vultures or hawks) have “built-in binoculars” in their eye. Part of their field of vision magnifies objects, and the anatomy of the feathers above the eyes forms a sunshade – which is why birds of prey often appear to look “fierce.”

Birds have a different view of the world than we humans do. Thanks to Swedish researchers, we now know how they see and what advantage this gives them in finding their way through the dense and confusing leafy forest.

Animals see with completely different eyes than we do. This is due, among other things, to the different color perception. The decisive factor is the number of so-called cones in the retina.

Most mammals, such as dogs and cats, have two cones. They see the colors green and blue. Humans and some monkeys have three cones for red, green and blue. Insects, reptiles, amphibians, fish and birds have four cones. So they see everything a little more “colorful” – for example, in the yellow or ultraviolet range of light.
