7.27 percent, according to the latest census carried out in 2016. With this upsurge in the population, authorities are planning a possible transfer of some wild water buffaloes to the flood plains of Chitwan National Park where they have been extirpated around 1950's. If the proposed translocation happens, this will present a natural Predator-Prey scenario since wild water buffaloes in Koshi Tappu has been lacking their natural predators in the form of tiger, leopard and dhole for quite a long time. Birds Notable among the 485 bird species are watercock, Indian nightjar, dusky eagleowl, black-headed cuckooshrike, whitetailed stonechat, striated grassbird, large adjutant stork, Pallas’s fish eagle, common golden-eye, and gullbilled tern. Swamp francolin and rufous-vented grass babbler occur as well. In spring 2011, 17 Bengal floricans were recorded from nine different sites along a north-south stretch of the Koshi River. Seven were males and 10 were females. Only five individuals were recorded outside the reserve, two pairs north of Koshi Tappu, and one female seen twice near the Koshi Barrage area.
