Ftaiii. Picidae. 



86. Picus canus occipitalis Vig. — This species was one of the most comnion 

 Woodpeckers met vvith in the dry forests in Northern Siarn. It is a very noisy bird 

 and its penetrating cry often rings through the woods. They seem to live in small 

 parties of aboiit 4 to 5 birds and I never observed them singly or in pairs either 

 at Den Chai, Meh Lera or Vang Nun, places were they were very abundant.

87. Picus chlorolophus chlorolophus Vieill. — The dry forests in Siara are 

 of coiirse splendid liunting grounds for different kinds of Woodpeckers. This small 

 yellow-naped Woodpecker was fairly common in the forests surronnding both Pak 

 Pan and Den Chai as well as round Non Luum and Sakerat, extending to the East 

 into Cochin China and Tonkin.

88. Gecinus nigrigenis Hume. — This form inhabits Siam and during my 

 journey I observed it several times, especjally in the dry forests of Northern Siam 

 for iiistance at Den Chai and in the valley of the Meh Yome river. Unlike Picus 

 canus occipitalis Vig. this species was always seen singly or in pairs, but never in 

 flocks. Like other Woodpeckers it is very noisy and its call resembles that of our 

 common Picus viridis L. 



A female shot near Pak Pan on the I7th of February measures as follows: 

 Length =315 mm., Wing = 151 mm., Tail = 122 mm., Culmen = 31 mm. 



89. Gecinus erythropygius Elliot. — I only succeeded in getting one single 

 specimen of this rare Woodpecker whose real distribution is confined to Cochin China 

 and the French Laos countries.
