BIRDS AS LIVING CREATURES..

God creates many living things that made every each of them have their own benefits in balancing the biomes. Biomes is a large area with similar flora, fauna, and microorganisms. Most of us are familiar with the tropical rainforests, tundra in the arctic regions, and the evergreen trees in the coniferous forests. Each of these large communities contain species that are adapted to its varying conditions of water, heat, and soil.

Biomes here can also refer to the word of the Nature which is not only consists of beautiful things, but it also offers an abundance of fascinating, exciting, intresting and very great new discoveries of the creatures evolution that waiting for us to discover the amazing thing about them. For instance, BIRDS in our discussion reveal many beatiful and unique things about them as we going deeper and deeper to know them.

When we talk about birds, there are a lot of species that we can found and doing research about them. Other than species, we may know how these BIRDS has been evolved and how they survive through out the times until they become modern birds that may adapt to the nowadays condition..

Their features, unique characteristics and many more make them one of the great creatures that God had given life to and fulfill the perfectness of this beautiful world...

BIODIVERSITY AND EVOLUTION SIMPOSIUM

Symposium is one of the mini project that BIOLOGY students should familiar with because this project is include in the lecturers evaluation mark on how do we perform in managing and presenting information we have in the topic specialized.

This symposium had been done on Monday, April 5th at Bangunan Canselori.

EGGS AND HATCHING

TYPES OF EGGS

While most eggs are oval and have a camouflage pattern, there are variations. Eggs laid out of sight in dark holes, for example, are white. Gamebirds and owls lay spherical eggs, while wading birds lay pear-shaped eggs. Aerial species such as Swifts have narrow bodies so they lay longitudinal eggs. The pear shape of the Guillemot’s egg prevents it from rolling of the narrow cliff ledge it is laid on.

THE HATCING PROCESS

Chicks call to each other and to their parents from within the egg, helping to co-ordinate their hatching. They use a tiny “egg tooth” on the bill tip to break the shell and then struggle until they push the two ends apart.

BUILDING A NEST

A bird’s life, behavior and appearance revolve around finding a mate and producing eggs in order to ensure the survival of its genes. The nest is a safe place to lay those eggs, incubate them, and raise the resulting brood, so individuals will spend time locating and building the perfect nest for their situation. Birds use nests to protect eggs and nestlings from predators and adverse weather. To minimize predation, birds may use or build nests that are inaccessible, hidden, or camouflaged. Nests may also help keep eggs and nestlings warm.

Types of nests:

Scrape nests are simple depressions in the ground (sometimes with a few stones added) or in the leaf litter. Such nests are used by some penguins, shorebirds, gulls, terns, nighthawks, vultures (e.g., Black Vulture nest below), and other species.

Burrow nests are very effective at protecting eggs and young from predators & maintaining an appropriate microclimate for eggs & young. Some birds, like Bank Swallows and Belted Kingfishers (pictured below), usually construct their own burrows, while others, such as Burrowing Owls, may use burrows contracted by other species.

Cavity nests (e.g., in trees or cacti) are used by numerous passerines, woodpeckers, owls, parrots, and some waterfowl. Some birds, such as woodpeckers (like the Gila Woodpecker below), construct their own cavity nests and are referred to as primary cavity nesters. Species that use natural cavities or cavities constructed by primary cavity nesters are called secondary cavity nesters.

Platform nests are relatively flat nests that may be located on the ground, in a tree, or on the tops of rooted vegetation or or debris in shallow water (like the Western Grebe nest below).

Cupped Nests are, of course, cup-shaped. Such nests may be constructed of various materials and in a variety of locations.
