Ratu, a Sumatran  rhinoceros, is pregnant. This is newsworthy because Sumatran rhinos are endangered and births in captivity are incredibly rare. Ratu’s mate, Andalas, was the third Sumatran rhino born in captivity in 112 years. If all goes well, Ratu’s baby will be the fourth.

Sumatran rhinos are the most endangered of all rhinoceros species. Their numbers have decreased due to habitat loss and human poaching.

The maleo is an endangered bird found only on the island of Sulawesi, in Indonesia. The maleo is about the size of a chicken, but it lays eggs up to five times as large as chicken eggs. The bird has yellow facial skin, a red-orange beak, a black ‘helmet’, and a black back and pink stomach.

Recently, the conservation of this strange bird has been helped by the purchase and protection of a stretch of beach used for breeding. The maleo buries its eggs in the warm sand of the beach to incubate. The eggs are then abandoned. Upon hatching, the chicks are able to fly and live on their own.

The stretch of beach was purchased for approximately $12,500. Funds were donated by the Lis Hudson Memorial Fund and the company Quvat Management. The 36 acre beach is now owned by Pelestari Alam Liar dan Satwa, known as PALS, a local conservation group.
