Recording a new species of Eurasian Spoonbill in Dong Nai Culture and Nature Reserve

One of the biggest issues facing us right now is climate change. Its effects on animals both in their residence and food source. As a result, migratory species is not an exception. In recent times, we recorded a new species of Eurasian Spoonbill at Sub-zone No.116 in Dong Nai Culture and Nature Reserve.


Eurasian Spoonbill

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

This is a Palearctic species, breeding from the United Kingdom and Spain in the west through to Japan, and also in North Africa. In Europe, only The Netherlands, Spain, Austria, Hungary and Greece have sizeable populations.

According to some scientists, in 2005 in Vietnam, they also appeared in Tien Hai district, Thai Binh province and Bien Hoa City, Dong Nai province. However, it has been recorded only in Xuan Thuy district, Nam Dinh province.Eurasian spoonbills show a preference for extensive shallow, wetlands with muddy, clay or fine sandy beds. They may inhabit any type of marsh, river, lake, flooded area and mangrove swamp, whether fresh, brackish or saline, but especially those with islands for nesting or dense emergent vegetation (e.g. reedbeds) and scattered trees or srubs (especially willow Salix spp., oak Quercus spp. or poplar Populus spp.). 

 

 

In the world, this species is protected by law in many countries such as China, Taiwan, North Korea, South Korea and Japan. Their breeding area in North Korea was designed to establish seabird conservation area.

             The emergence of Eurasian Spoonbill were added to the list of rare bird at Dong Nai Culture and Nature Reserve. It proves that Tri An Lake belongs to the routes of East Asia and Australia (Wetlands International, 2002) and is a very important area for the migratory birds.

            It shows that the natural resource conservation in the reserve performed well. It can attract more scientists and students visiting and studying about birdlife in the furture.
