The Swift is a bird name that surely needs no explanation. Many taxonomists of avian specialty refer the convergence evolutionally of the Swift to the Swallow, in function and flight use. The vertical wing span and flying glide of the Swift operates to keep it airborne, settling for short perch maneuvers briefly. References to Swifts in antiquity and the Middle Ages present the bird as a very august survivor indeed. Here are some examples of the Swift species types found all over the world. Knowing some key characteristics of the Swift can make a bird enthusiast out of the most casual observer with a few facts.The Swift comes in many shapes and sizes. The Fork-Tailed Palm Swift likes a marshy open area or forest patch, notably in Peru or Venezuela. The Palm Swift with the forked tail builds an unclosed circular nest with feathers, vegetations, and its own saliva. Contrast this habit to the Asian Palm Swift, which builds its nest to the underside of a palm leaf. Some Swifts are larger in the body and have larger wingspans, others have differentiated builds and wing shapes to suit local native forest habitats.
The Palm Swift has a dark brown to black appearance with a slight glossy metallic green hue, which imitates the very insects it hunts। The call of the Palm Swift likewise makes a sound that might confuse insects until it’s too late. But if the locale is not Asian, then the bird is likely a Swift with a forked tail which nests inside the leaf. If the size is very small, the bird might be a Pygmy Swift.
Nests are big giveaways about what kind of bird you are looking at। The Swallow tailed Swift builds a tubular nest, out of vegetative matter but affixed to a stationary walls। This Swift is located in parts of Indonesia and India, as well as the Philippines. The Brown Backed Needle Tail Swift is a cliff nester and inhabits the rocky line of cliffs in its native shore land roosts. But the Needle Tail moniker suggests the aligned feathers of the tail stick together. This is one of several key differentiations from another type of Swift such as the fork tailed breed. Also, the Brown Backed Needle Tail Swift has a bulky middle torso that helps manage much more rapid flight patterns than a slighter bird.
