Park rangers in Indonesia said last week that they had photographed the nearly extinct Sumatran Ground-cuckoo (Carpococcyx viridis) for the first time in a protected area in North Sumatra. The sighting was about 300 kilometers (186 miles) north of the bird’s known range.

A camera trap in Batang Gadis National Park recorded the ground-cuckoo twice in one morning last November.

Based on the recorded images, park officials and experts from Conservation International (CI), identified the sighted bird as the Sumatran ground cuckoo, which is listed as Critically Endangered by the IUCN.

 

“This is the first time the Sumatran Ground-cuckoo was recorded in the national park,” Paul van Nimwegen, biodiversity conservation specialist at CI, wrote in an email.

Van Nimwegen pointed out that the images showed the bird “foraging và sunning on the forest floor.”

Endemic to lớn Sumatra, the bird — whose feathers are green và brown — was considered extinct until one was spotted in 1997 in Bukit Barisan Selatan National Park, which is located about 1,200 kilometers (745 miles) south of Batang Gadis National Park.

A few unconfirmed sightings of the bird, whose declining population is estimated at 50-249 mature individuals, have been reported since 2007, according to lớn the IUCN.

“Its discovery in Batang Gadis National Park indicates that there is a previously unknown population of this bird occurring in the area,” van Nimwegen said. “This is incredibly significant. The national park might be one of its last refuges,” he added.

The park’s management agency và CI have yet lớn carry out field research to obtain more information. Van Nimwegen noted that it was “very difficult khổng lồ obtain physical evidence” as there were only eight known specimens of the species.

The cuckoo lives in the foothills & in lower montane forests. It feeds on reptiles & small mammals, according lớn the IUCN.

Inaugurated as a national park in 2004, Batang Gadis covers about 70,000 hectares (270 square miles) of land with an altitude ranging between 300 lớn 2,145 meters above sea level. The park is also known lớn house the densest population of tapirs in Southeast Asia.
