the \ear round, and as charmingly in January as in the month of roses and 

 home. They are somewhat exclusive, as you will find but one pair in a 

 place. They have four or five young at a brood; in some cases. I think, 

 thev remain mated through the winter. 



In descriptions of the bird no one seems to have noticed the bronzed 

 head and neck of both sexes in spring. The whole head is beautifully 

 bronzed from pink and purplish reflections. 



Has any one seen a Dipper perching? I was surprised one day, while 

 walking along the river, to see an Ouzel fly up from the water into a bush 

 where he hopped around .quite as unconcernedly as any orthodox percher. 



7. Regulus calendula. Licht. Ruby-crowned Kinglet. — Very 

 abundant from April to October; breeds from 7,500 feet to 10,500 feet. 

 A nest, which I took July 5, was placed in the uppermost branches of a 

 spruce — about 30 feet from the ground — in one of those dark masses 

 where the cones grow thickest, and where it would be impossible to see 

 your hat. were it there. The nest was very loosely placed among the outer 

 twigs, being partially pensile, and was composed of bits of fine bark ex- 

 ternally, and within of silk-weed shreds, moss, spider's silk, and feathers; 

 all matted together in a compact manner, and lined with wool. It con- 

 tained four young and an addled egg, the latter measuring .014 X .012 

 mm. ; white. 



Following is a description of the nestling plumage. Top of head dark, 

 almost blackish. Back and rump a light tint of olive-green. Beneath a 

 dirty rusty white, darkest on fore-breast. Lores lighter than rest of head. 

 Primaries and secondaries black, edged on inner margin with white: this 

 white is Only on basal half of second primary, but gradually extends 

 until it reaches the tip on the last secondary. Outer edge of second prima- 

 ry white. On the basal third of third primary, the yellow edging of the 

 outer margins of the wing feathers begins and. slightly widening, rapidly 

 extends so as to conspicuously color the secondaries and tertials. The 

 outer webs of the latter have quite a wide whitish band which is edged 

 with greenish-yellow. Greater wing-coverts with a terminal band of dirtv 

 white. Tail feathers black; outer pair completely so. rest with greenish- 

 yellow margin. Tarsi marbled light and dark. Toes, above flesh color, 

 below yellow. Bill dark above, below flesh colored, pink at base. Meas- 

 urements of one example: — Length. .oSS: extent. .162: wing, .052: tar- 

 sus. .02 : tail. .027 mm. 



8. Regulus satrapa. Licht. Golden-crested Kinglet. — Rare; 

 a single bird found in September, 1S79. 



9. Lophophanes inornatus. Bd. Plain Titmouse. — Not uncom- 

 mon in September, and doubtless breeds. 



10. Parus atricapillus septentrionalis. Allen. Long-tailed Chick- 

 adee. ■ — A very common resident; breeds. 



11. Parus montanus. Gamb. Mountain Chickadee. — Fully as 

 abundant as the foregoing; ranges from the Park to the summits of the 

 loftiest peaks. The only difference I have noticed between this bird and 

 it> congeners is that cktck-a-dee-dee i-- uttered in a sharper, more wiry 

 tone: the young (?) birds frequently utter a sharp, disagreeable squeak.
