Owl is a large nocturnal bird. It has a round and flat face with hooked beaks, static eyes, and large ears. Its neck is flexible and can turn over 180 degrees on both sides. This allows the bird to look around and backward even with its fixed eyes. The bird cannot see color but its visual clarity is sharp. Its ears are asymmetrical but acute in discerning sounds from different dimensions. Owl is commonly seen standing in upright position. Its plumage is soft and heavy. The color varies for different species, from grey to brown to reddish brown. The plumage mostly have markings on them, camouflaging the owl amidst dense foliage. The fossils of owls are dated back to over 65.5 million years. At present, there are about 250 species in the Owl family.

Their plumage is either brown or grey with white streaks. The feather on their belly is usually white. The birds have a long and stiff tail. An interesting fact about Sparrows is that they have a bone in their tongue. As these are perching birds, they have clawed feet with three forward-pointing and one backward-pointing toe. Sparrows are songbirds that make chirping sounds. There are over 140 species of these birds in the world. They are generally classified as Old World species and New World species. Sparrows are mentioned in mythology and the Bible. Their earliest fossils, found in caves in Israel, are dated back to over 100,000 years.

Where are Owl and Sparrow found?

Owls live in diverse habitats such as forests, mountains, plains, and deserts. The Snowy Owl lives in the frigid regions of North Pole. Species like Great Horned Owl and Barred Owl can be found in cities. Owls can be found in all countries of the world except Antarctica.

Sparrows prefer thick forests, open fields, agricultural farms, and fringes of forests. However, a large population of Sparrows also live in the parks, gardens, and buildings of cities. The Old World species of Sparrows originally belong to Asia, Africa, and Europe. The New World species have been introduced in North America, South America, Australia, and New Zealand.

Where do Owl and Sparrow nest?

Owls do not build nests. They use holes in trees, quiet places in barns and buildings, caves, natural cavities in river banks, and nests of other birds to lay their eggs.

In the nesting season, the female develops additional feathers, called brood patch, on her belly to provide warmth during incubation. The eggs hatch 32 days after incubation. The young ones fledge when they are six to eight weeks old.

Sparrows build their nests in holes and cavities of small trees, in shrubs, and buildings. They prefer their nests to be closer to the ground. The nests generally look spherical and measure eight to 10 inches in diameter. The female and male partners construct the nest using straw, twigs, roots, leaves, grass, paper, thread, wool, and feather. The eggs are completely white, or bluish white, or greenish white with brown spots. Both partners incubate the eggs. The eggs hatch in 10-14 days. The young ones that are fed by both parents fledge in about two weeks.

In Europe, the Scops Owls migrates to the tip of the Sahara Desert. The Short-Eared Owl is another migratory Owl from India that travels long distances, sometimes even crossing oceans.

Not all Sparrows are migratory. The ones from Canada, North America, northern parts of Europe, and east Asia migrate during winters. The House Sparrows typically do not migrate as they do not encounter harsh weather or scarcity of food in any time of the year. Among the migratory species, American Tree Sparrow migrates from North America and Canada to the USA, while the Savannah Sparrow travels from Alaska to the USA.
