Oh, never a brute in the forest,
And never a snake in the fen,
Or ravening bird, starvation stirred,
Has hunted its prey like men.
For hunger, and fear, and passion
Alone drive beasts to slay,
But wonderful man, the crown of the plan,
Tortures, and kills, for play.

He goes well fed from his table;
He kisses his child and wife;
Then he haunts a wood, till he orphans a brood,
Or robs a deer of its life.
He aims at a speck in the azure;
Winged love, that has flown at a call;
It reels down to die, and he lets it lie;
His pleasure was seeing it fall.

Savage-Rumbaugh's work with bonobo apes, which can understand spoken language and learn tasks by watching, forces the audience to rethink how much of what a species can do is determined by biology -- and how much by cultural exposure.

One of India's main tiger parks - Panna National Park - has admitted it no longer has any tigers.

The park, in the central state of Madhya Pradesh, was part of the country's efforts to save the famous Royal Bengal Tiger from extinction.

State Minister of Forests Rajendra Shukla said that the reserve, which three years ago had 24 tigers, no longer had any.

A special census was conducted in the park by a premier wildlife institute, after the forest authorities reported no sightings of the animals for a long time.

This is the second tiger reserve in India, after Sariska in Rajasthan, where numbers have dwindled to zero.
