Parus hudsonicus Forst. Hudsonian Chickadee 



1. Natal Down. No specimen seen. 



2. Juvenal Plumage acquired by a complete postnatal moult. 



Above, brownish mouse- gray, the pileimi pinkish drab-gray. Wings and tail dull 

 slate-gray whitish edged, the coverts edged with pale wood-brown. Below, 

 including suborbital region and auriculars dingy white and washed on the sides 

 and crissum with pale cinnamon, the chin and throat dull black. Bill and 

 feet dusky pinkish bufif, becoming slate-black. 



3. First Winter Plumage acquired by a partial postjuvenal 

 moult, beginning early in August in eastern Canada, which in- 

 volves the body plumage and wing coverts, but not the rest of 

 the wings nor the tail, young and old becoming practically in- 

 distinguishable. 



Similar to previous plumage, the pileum darker and the back browner, contrasting 

 but slightly with the cap ; the flanks, sides and crissum rich Mars-brown ; the 

 black on the throat deeper and the white of the sides of the head and lower 

 parts clearer. 



4. First Nuptial Plumage acquired by wear, the flanks, 

 sides and crissum becoming cinnamon through fading, the back 

 grayer and the cap paler. The plumage becomes ragged by 

 the end of the breeding season, due no doubt to the species living 

 among spruces and suffering by abrasion from the harsh foliage. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult in August. Practically indistinguishable from 

 first winter dress. 



6. Adult Nuptial Plumage acquired by wear as in the 

 young bird. 



Female. — The sexes are alike and the moults correspond. 



SYLVIID^ 



The Kinglets have an annual moult, the young males of 

 both species assuming the colored crown patches at the postju- 

 venal moult. Polioptila ccendea has a semi annual moult. 



Regulus satrapa Licht. Golden-crowned Kinglet 

 1. Natal Down. No specimen seen.
