paler than the average. None, however, are wholly white as in the 

 northern races. 



To the north this race extends through the mountains of Costa 

 Rica. A series from that country agrees in small size with the birds 

 of Panama. Skutch (Anim. Kingdom, 1956, p. 53) records this 

 southern hairy woodpecker as similar to Centurus rubicapilhis in its 

 family arrangements, which indicates that male and female share in 

 incubation during the day, with the male occupying the nest alone 

 during the night.
