Smugglers cram cockatoos into plastic bottles to get them through customs

Smugglers crammed the Yellow-crested cockatoos into empty bottles so they could get through customs at Port of Tanjung Perak in Surabaya, Indonesia.

But Indonesian Police discovered the birds, which can be sold for as much as £650 each, and cut them free so they could receive medical attention.

The Yellow-crested cockatoo was listed as a critically endangered species by the International Union for the Conservation of Nature and Natural Resources in 2007.

The population is at a critical low due to deforestation and poaching and recent studies suggest there may be less than 7,000 individuals remaining.

More than 10,000 parrots, including Lories and Cockatoos, are caught from the wild in North Halmahera, Indonesia, each year to supply the domestic and the international illegal wildlife trade.

Around 40 per cent of birds die during the illegal smuggling process. 

So for every 1,000 parrots caught from the wild, 400 birds died in vain, during the poaching, transportation and trade, due to poor conditions and cruel handling.

Most parrots are prohibited from international commercial trade unless they are captive bred or permitted by the exporting country. 

Yellow-crested cockatoos also breed very slowly and lay eggs only once a year. They can produce only two eggs at a time.

Illegal trapping continues in many areas including Rawa Aopa Watumohai National Park, Buton and Kadatua Islands, but has reportedly been reduced significantly on Sumba.

Large-scale logging and conversion of forest to agriculture across its range has exacerbated the decline, and the use of pesticides is a further potential threat. 

The white birds can range in size from 12 inch to about 27inch in length and present a beautiful yellow crest.

They are found in wooded and cultivated areas of East Timor and Indonesia's islands of Sulawesi and the Lesser Sundas.
