Nguyen Duc Anh, deputy head of the provincial Forest Protection Department, said on April 17 that the birds, locally known as co nhan and listed in Vietnam’s Red Data Book, have been seen in large numbers, possibly in the thousands, in Binh Kien and Tuy Hoa wards.
The species, Asian openbill stork, is found across South and Southeast Asia and is considered rare in Vietnam.
Preliminary surveys show the birds forage in rice fields during the day and roost at night in trees and shrubland around Chop Chai Mountain and nearby areas.
Following reports that some individuals have attempted to trap the birds, authorities have stepped up patrols and urged local governments and forest rangers to strengthen protection at feeding and roosting sites.
Public awareness campaigns are also being intensified to discourage hunting and encourage residents to report violations such as trapping or illegal trade.
Officials said inspections would continue in key areas to prevent poaching and ensure the flock’s safety.
