Downy Woodpecker, Dryobates pubescens. This is the smallest of our wood- 

 peckers and is a common resident. The male has a scarlet band on the nape, 

 which is absent in the female. It much resembles the downy woodpecker in appear- 

 ance, but is a quieter bird and much smaller in size. It is one of the most useful 

 of the family, destroying large numbers of wood-boring larvae and caterpillars, 

 even feeding on larvae of the codling moth. 



Hairy woodpecker. 



Hairy Woodpecker, Dryobates villosus. — This is another common woodpecker 

 much like the downy in appearance, but is a noisy, restless bird conspicuous by its 

 loud calls and flights from tree to tree. It is also a resident and a valuable de- 

 stroyer of forest insect pests. 



Three-Toed Woodpecker, Picoides arcticus, P. americanus. These wood- 

 peckers are valuable birds, but are rare. The Arctic three-toed woodpecker may 

 be recognized by its shining black back and, in the m^le, an orange crown patch. 

 The American three-toed is somewhat similar, but the back is barred with black 

 and white.
