19. Junco hyemalis (Linn). — Slate-COLORED Junco. One 

 adult male and one immature male, February 26 and Marcb 

 25. Taken from mixed flocks of j uncos. 



20. Junco meamsi Ridgway. — Pink - sided Junco. Two 

 adult males, February 26 and March 13. Taken mixed in with 

 the other forms of Junco on the side of the mountain. 



21. Junco annectens Baird. — Ridgway Junco. One male 

 adult, March 8. Ridgway (Birds of North and Middle Amer- 

 ica, pt. I) calls this "species" a hybrid, Junco caniceps x Junco 

 meamsi. It was taken from a flock and its identity not noticed 

 till later. The flanks are very strongly tinged with pink, and 

 there is a little brownish wash on the tertials and greater 

 wing coverts. The measurements taken from the skin are as 

 follows : 



Length. Wing. Tail. Culmen. Tarsus.

22. Junco caniceps (Woodh.) — Gray-headed Junco. Seven 

 adult males, February 23; March 2, three; March 4, twor 

 March 11. One adult female, March 11. In the field this bird 

 could not be separated from Junco dorsalis, and in fact it was 

 almost impossible to name any of the species of Junco present 

 here, unless they were in the hand. When I first came these 

 birds were found only in the shelter of the low pines, but as 

 the migration began they became common everywhere. 



23. Junco dorsalis (Henry). — Red-backed JuNCO. Nine 

 adult males, February 23, March 2 ; March 8 ; March 11 ; March 

 19, two; March 21, three. One adult female, March 11. This 

 species, together with Junco caniceps, formed the bulk of the 

 j uncos seen. The two species were mixed together, and ex- 

 amples of the others were also found in the same flocks, so 

 that identification without the gun was impossible. When I 

 first arrived there were only a few present, and I found them 

 roosting in the low pines on the side of the mountain. After 

 the first week in March they became more common, and were 

 scattered in small flocks all up and down the mountainside, 

 and, as they became more numerous, also spread to favorable 

 situations on the level. When disturbed on the mountain, they 

 flew up into the trees with the usual junco call-notes, and 

 moved rapidly along up the slopes. They usually came back 

 after a few minutes, seeking a lower level. On cold, windy 

 days, they fed in the shelter of numerous deadfalls, from which 

 it was almost impossible to flush them. Junco dorsalis gave a
