The Ralli, rails or Rallidae comes as largely some of the cosmopolitan types of medium and small sized birds. Within this family, there is a show of huge diversity while the family is also comprised of coots, gallinules and crakes. Lots of species of the Ralli have been in association with natural wetlands, as much as it is found in most land habitats, except in very dry deserts, alpine areas slight above on the snow line and Polar Regions. Except in Antarctica, Ralli members are found basically on every continent. From island species large in numbers, the list of Rallidae is very huge. Some of the more common habitats include dense forests and marshy areas, where the rails are largely ford of vegetation that is densely intense. Ecology and Behavior The Rallidae members are generally omnivorous. There are so many species ready to feed on invertebrates, seedlings and fruits. A couple of species are largely vegetarians, primarily. The kinds of calls they make are largely loud and varied, where some are squeaky or like whistles. This is because within dense vegetations or even after sundown it is not easy to see the other species while other calls are just territorial markers. Reproduction The breeding trait of these species is unknown and poorly understood. There is a widespread thought that most of them are monogamous, as much as polyandry and polygyny has been reportedly ascertained. The eggs are usually 5-10. There are cases where there are even 15 eggs that have been reported. Ralli and Humans In most Ralli-humans associations, the case has been the largely abundant rails being hunted for food, as well as their eggs. Also, the Gallinule and Common Moorhen has been considered as pest. Flight The Rallidae wings of all rails are round and quite short. For the flight of those Ralli that can fly, as much as it might not be very powerful, it can be sustained for a longer period while these species are known to undertake yearly migrations. Since their flight is rather weak, it has however meant that they are sometimes thrown off their course and are considered as common vagrants, a trait that led them to end up colonizing most of the oceanic islands that seem isolated. In addition, these birds are known to prefer running than flying, more so when they are within denser habitat. Others are even without flight mostly during the moult period in their growth. Also, some Ralli commonly found in many islands have no flight since there is usually no predatory menace and the flight ability is usually eliminated. Menace and conservation Since most of the Ralli species have very limited flight ability, so many islands Ralli species hardly cope with the introduced species. They have become extinction in some islands in the Pacific Ocean after the encroachment of people in such islands as Micronesia, Polynesia, Melanesia, where about 750 to 1800 bird species became extinct, half of which were Ralli. But some conservation efforts have made sure some of the species are still available.
