Tlio Parus sibiricus, of Europe, is very similar in coloration and 

 characters to the P. hudi^oincus. The principal diifercnce is seen in 

 the cheeks, which in sihiriciis are pure white, this color extending 

 along the entire side of the neck, widening behind, and extending 

 round towards the back. In hudsonicus the checks behind the eyes 

 and sides of neck are ash gray, the white being confined to the region 

 below or near the eye. The smoky gray of the upper part of head 

 and neck in sibiricus is in a stronger contrast with the brighter 

 rufescent gray of the. back, and is separated from it by an obscure 

 concealed whitish dorsal half collar, represented in hudsonicus only 

 by a dull grayish shade in tho plumage.
