The Types of Swift

Swift coming from families apopidae, spread almost all over the world, apopidae family consists of two groups. The first group is a Swift tail genus (Chaetura genus), group of cave swiftlets (genus colacalia) and black Swift of North America (genus cypseloides).The second group is the genus apus.
Two species which well-known in the business world is Collocalia Fuciphaga Collocalia Maxima. Collocalia Fuciphaga are found in Sumatra, Java, Borneo and also in some islands in Nusa southeast, while the Maxima Colocalia numerous in Borneo and Sumatra.Both species nest distinguished experts into some kind of group or race, so Collocalia Fuchiphaga located in Java and Kalimantan not necessarily come from the same race.

 Edible nest Swiflet ( Collocalia Fuchipaga) has another name that is German Swiflet; Brown- Rumped Swiflet;Areo dramus fuchiphagus. Edible nest Swiflet has many race: 

• C.f Fuchiphaga is spread in Java, Kangean Island and Belitung.
• C.f Perplexa is spread in Maratua Island (East Kalimantan).
• C.f Dammermani is spread in Flores.
• C.f Micans is spread in Sumba, Sewu anf Timor. 
• C.f Vestita is spread in Kalimantan and Sumatran 
• C.f inexpectata is spread in Andamar Island and Nicobar.

Black Nest Swiflet (Collocalia Maxima) has another name that is Low's Swiflet, Robinson's Swiflet,Indo Malayan wiflet, Aerodramus Maximus. Black Nest Swiflet has many race too that is:

• C.m Maxima is spread in Sumatran and Nias Island.
• C.m Lowi is spread in west Kalimantan, Labuan island, West Java, palawan.
• C.m Tichelmani is spread in the southeastern kalimantan.

the classification of swift is:                            

Superoder  : Apomorphae                 

Order         : Apodiformes 

Family        : Apodidae

Sub Family : Apodenae

Tribes         : Collacaliini

Genera        : Collacalia

Species       : Collacaliafuciphaga

Swift have a close kinship with the Kolibri . Both groups of birds are included in the same ordo that is apodiformes. All kinds of swift  have a similar body shape, but the shape can be identification from it's body size. If the size of it's head and body about 16 centimeters and the style fly is circle suspected species Hydrochaous gigas. Species Collocalia esculenta, Aedramus Fuciphagus, aerodramus vanikorensis, Aerodramus Brevirostris and aerodramus Maximus, has same shape and the style fly with Hydrochaous gigas , the size of it's body is smaller than Hydrochaous gigas.

Sapi Swift (Collocalia esculenta) is often referred to as white-bellied swiflet meaning white-bellied swallow.This bird is also commonly called as "sriti". Her size is only 10 centimeters wide wingspan reaches 21 centimeters. Upper body is greenish black, the lower part of his dark gray. The belly is whitish special features to white-bellied swiflet. This makes the nest of white-bellied swifletbonded with a little saliva, this nest edible but contains a lot of grass need to be cleaned before processing. White-bellied swiflet makes the nest in a rather light near the mouth of the cave, a rock crevice or nook corner of the building. White-bellied swiflet spread Himalayan region, Asia, Papua New Guinea, and Australia.

 White-bellied Swiflet

The nest of   White-bellied Swiflet

Aerodramus Vanicorensis sometimes called moss-nest swiflet has a small size. The feather darker colour and tail parts are not so deep. This bird has a habit of flying with rigid wing movement. typically in the form of high-pitched voice "tsyir" usual buzzing sound close to the breeding.

Swift an Unique Animal

The swift is one of unique animals, because it looks for food and breed in the air. The swift has the structure of strong chest muscles, that enables it to fly for 40 hours without stopping. The ability to fly can reach 150 km/hour with wings like the crescent. It is a small bird with a forked tail. It has long and pointed wings. Its wings are 12 centimeter long but when they strech it can reach 25 centimeter long. It legs are just for creeping and adhering on the cave walls or cliffs, because they are very small and weak, it can't walk or jump.

The way how a swift makes its nest is also very unique. A pair of swift, male and female take turn to spread their saliva to the cave walls or the roof of the house where it wants to make its nest. this nest contains protein and minerals such as calcium, iron phosphorus, calium and natrium. In a day they can only make a nest. It takes 30 or 40 days to finish it. In the day season it takes 80 days. The shape of the nest is like a bowl  splitted into two. It lays 2 eggs and it breeds 3 to 4 times a fear cach time when the swift breeds it will thicken its nest to make it stronger. It feeds on insects which fly around the rice fields plantations and marshes, etc.
