44. Whitehead's Nuthatch, Sitta canadensis whiteheadi Sharpe 

 [P. Z. S., 1884, p. 233, 414]. This very interesting isolated 

 form was discovered by Whitehead in 1883. In the following 

 year he found 9 nests, some of which however were in- 

 accessible, being from 70 to loo ft. from the ground in trees 

 in the last stage of decay. The locality was kept secret by the 

 discoverer, but in 1896 Dr. A. Koenig obtained 5 specimens 

 in the Vizzavona forests, and subsequently A. D. Sapsworth 

 found the bird common in autumn at one spot in another
