we have ever heard. It begins with a series of notes precisely like the 

 'song' of a common hen magnified about fifty- fold, and ends with an 

 indescribable combination of cackles and shrieks.

"We saw this bird on several occasions in Palawan, but always in 

 very high trees, and it was so extremely wild that we did not succeed in 

 securing any specimens from that island. In the Calamianes Islands 

 we found it both common and tame. On several occasions we saw it 

 feeding in low fruit trees within a few feet of the ground.

 of lower mandible; bare skin of head white. A female measures, 610 in 

 length; wing, 263; tail, 204; tarsus, 46; middle toe with claw, 58."
