Bangladesh Forest Department in cooperation with the Joint Forces rescued the birds from a house at Sen Gupta Road in Chandpur district on Friday.

The rescued birds include three large flamingos, one pelican, two white-necked storks, two painted storks, two storks, 11 common fowl, four emus and a lesser adjutant stork.

Of them, painted stork, pelican, lesser adjutant stork, white-necked stork and common fowl are enlisted as rare and endangered species of birds in Bangladesh, sources said.

Project Director of Dulahazara Safari Park Dr Tapan Kumar Dey said some poachers kept them in cages, which is a threat to the biodiversity of the country.

"Research works would be carried out at the Park to find out ways to reproduce the species," he added.

The prices of these birds would be around Tk 15 lakh in international market, he observed.

So far, a total of 148 animals and birds of different species, out of 186 the Department of Forest rescued from different parts of the country with the help of joint forces in the last two months, were released at the Park, he added.

On Wednesday last, two zebras and two wildebeests of rare species were released at the African Safari Encircles inside the park to enrich it.
