Some authors have argued that human preferences for “beautiful“ birds may skew the selection of species used to promote conservation programs. This evokes questions about the importance of color, shape, and other appearance traits of bird in affecting human preferences for birds. The aim of this study was to assess the traits affecting human preferences towards all non-passerine and five passerine bird families (n = 102), and to see whether such preferences correspond within a family or are species-specific. Using an Internet survey, we asked 200 human respondents to evaluate pictures of bird species, with two randomly chosen from each family, according to their attractiveness. The respondents were mainly from the Czech and Slovak Republics, but 67 came from other countries (the majority of which were English-speaking). An additional 100 respondents, exclusively from the Czech and Slovak Republics, evaluated the same pictures converted to silhouettes, to test the effect of shape versus color. We included various factors such as morphometric traits (i.e., measurements of body segments and the area the bird silhouette filled in the picture), body weight of the species, and colors, lightness, and saturation of the pictures in the statistical analyses, to help explain any variation in human preferences. We found that human preferences were significantly affected by bird morphology; however, the colors blue and yellow, as well as the overall lightness, were significant as well. The preferences for species belonging to the same family were positively correlated, possibly due to similarity in the body shape of related species. We suggest that finding the traits that determine human preferences toward birds may help conservationists promote a conservation program based on the selection of the correct, scientifically determined, flagship species.Yes, birds are beautiful to look at, but the beauty of birds is not confined to the visual aspects of shape and color alone, because birds also fill the air with music. They seem to offer us their song simply to entertain us, and they ask for nothing in return. Like a garden bursting with colorful flowers, the fantastic colors and songs of birds seem frivolous and out of place in a world full of harsh realities. It seems as though they were put on earth expressly to make life more beautiful. They were not, of course. Their color and song serve biological ends in the process of natural selection, but that does not prevent us from enjoying such sights and sounds. We can listen in on their free concerts and derive pleasure and serenity from the experience. We can also be amused when a few species of birds even mimic our own speech.
Another characteristic of birds that we humans respond to is the fact that they build nests. They seem so industrious and we watch with wonder as each type of bird builds its own species-specific nest, ranging from a simple assemblage of twigs to an intricately woven masterpiece of craftmanship. "Nest" is such a cozy word. Birds build their cozy nests, care for their young, and raise their families, all in the course of a single spring or summer. We admire their patience and devotion and attentive care to their offspring. We observe and marvel at a parent bird's countless trips to and from the nest to diligently feed the helpless chicks. Birds provide us with fine role models for parenting.
Yes, birds are homebodies during the nesting season, but they also migrate. Birds are free to come and go and many cover vast distances each year, as they travel between their summer and their winter homes. They are social creatures, moving in flocks and creating great spectacles as they fly. A glimpse of a V-shaped flock of geese passing overhead thrills us and stirs something in us. We admire their strength and endurance in carrying out such grueling journeys year after year. We envy them, too, for they are free to go beyond mere political boundaries and to cross entire continents. We up north are sorry to see them part each autumn and we are heartened to see them return each spring. The return of such birds as the swallows signals the return of spring, with its promise of birth and renewal.
Each spring we are able to welcome them back into our midsts, for nearly everywhere that humans live, birds live also. Birds cover the earth. There is such a diversity of bird species to fill each ecological niche on earth and to contribute to its balance by doing such things as eating insects and dispersing plant seeds. There are the ducks and moorhens of rural ponds. There are birds who live in the forests. There are birds in the mountains and birds in the deserts. The forbidding oceans have their hardy puffins and pelicans. Even frozen, icy places have their own birds, the lovable penguins.
Birds adapt to so many different habitats and situations, including human environments. The often ignored pigeon is a beautiful bird. (I have cared for and been grateful to have known many individual pigeons over the years.) As a species, they have managed to adapt to modern cityscapes, substituting cliff-like building ledges and bridge girders for their ancestral cliffs of rock. Other bird species may be less tolerant of such disturbances and avoid the prying eyes of humans.
Wherever they choose to live, birds remain symbols of untamed nature, surviving despite man's interference with their habitats. They remain proud and free to the present day. They are also a living link to the mysterious and fascinating history of life on our planet, as birds are the surviving heirs to the dinosaurs. One look at unfeathered baby birds, with their oversized beaks and feet, and it is easy to see the dinosaur in them.
