You don't need any kit to enjoy the birds in your garden, however if you would like to make more of a hobby of it it's very easy to do. Those where the song is partly inherited, but the bird tunes it in by copying others. In this case the slight differences between the calls of different birds may be used by partners for identification.

Describe the sound you are hearing, either out loud to someone else or in your head. Does it stay at one pitch or go up and down? Is it loud or quiet? Fast or slow? Repetitive or varied? Does it remind you of another sound? Birds have wings. The wings develop differently in different species. The only known groups of birds without wings are the extinct moa and the elephant birds. Wings evolved from the forelimbs of birds. They give birds the ability to fly. Over time, many groups of birds evolved with smaller wings. These include ratites, penguins and many island species of birds. The digestive and respiratory systems of birds are also adapted for flight. Some bird species in aquatic environments have evolved as good swimmers. This is seen in seabirds and some waterbirds. Now you can draw in some feather details using a combination of more small, wavy lines and straight ones. Senter P. 2006.

ISBN 978-0-300-12539-9 Palaeontologists have found some exceptional places ( lagerstätten) where fossils of early birds are found. The preservation is so good that on the best examples impressions of their feathers can be seen, and sometimes even the remains of meals they have eaten. From these remains we know that birds evolved from small carnivorous dinosaurs ( theropods) in the Jurassic period. [41] They radiated into a huge variety in the Lower Cretaceous. At the same time, their direct competitors, the pterosaurs, dwindled in numbers and variety, and became extinct at the end of the Mesozoic. Lysaght A.M. 1975.

There are billions of bird lovers in the world, and they love to immortalize their favorite feathered friends in photos, sculptures, paintings and of course drawings. Many fossils of early birds and small dinosaurs have been discovered in the Liaoning Province of Northeast China. These include Anchiornis huxlei, from about 160 mya. [45] The fossils show that most small theropod dinosaurs had feathers. These deposits have preserved them so well that the impressions of their feathers can be clearly seen. This leads us to think that feathers evolved first as heat insulation and only later for flight. The origin of birds lies in these small feathered dinosaurs. You could also incorporate some lovely art mediums like watercolors for a softer look or acrylic paints for a more vibrant look. We can’t wait to see what you choose for your beautiful bird drawing! Do this to take your bird drawing to the next levelAlthough birds are warm-blooded creatures like mammals, they do not give birth to live young. They lay eggs as reptiles do, but the shell of a bird's egg is hard. The baby bird grows inside the egg, and after a few weeks hatches (breaks out of the egg). Most birds are social animals, at least part of the time. They communicate to each other using sounds and displays.
