Vol. XXXll Rockwell and Wetmore, Birds of Golden, Colorado. 315 



rather a surprise to find this bird here so near Denver, and whUe they were 

 not common, we saw frequent signs of their presence and occasionally 

 came across the birds themselves. Their favorite food was the kmnikmnick 

 berry which grew in abundance on Lookout Mountain, and all the grouse 

 observed were seen there. We fouhd feathers scattered about their dust 

 baths in sunny places and noted their tracks in the snow leading through 

 the forest growth. They were wilder here than they are back m the moun- 

 tains, and when flushed went off with a clucking note. On September 19, 

 we found a flock of seven in a weed-grown field and one was taken while 

 the others, all nearly grown young, flew into some pmes. The one taken 

 on that date stiU retains the juvenile plumage about the head and traces 

 of it persist along the median breast line. The band on the tail is also 

 darker than in the adult. 



8 Zenaidura macroura marginella. Western Mourning Dove. 

 - Common everywhere, from Clear Creek to the top of Lookout Mountain, 

 the first arrival being noted April 25. The first nests were found at about 

 7500 feet, on May 23, when two were examined. One of these nests was 

 built on a large flat rock on the very edge of a great precipice. The nest 

 was buflt entirely of pine needles, was shaded by a dwarfed cedar and 

 contained two eggs, one being a runt egg which measured only .76 X .bl 

 inches Two weeks earher we found nests on the plams. This species 

 continued common about Golden until the third week of August when 

 most of them disappeared. At this time they became more abundant m 

 the vicinity of Morrison and were perhaps attracted there from the sur- 

 rounding country by the grain fields which were being cut. Three taken 

 in Turkey Creek Canon August 29, had eaten sunflower seeds and another 

 smaU black seed which we did not recognize. The larger part of the birds 

 were gone by the middle of September, though one was noted on Clear 

 Creek November 16. , 



9 Cathartes aura septentrionalis. Turkey Vulture.- Noted

September 26. _. ^ , . •, 



10 Accipiter velox. Sharp-shinned Hawk.- First noted on Api 



14, and seen from then until the middle of May. The first bird of the fall 

 was seen in Chimney Gulch, September 19, when one dashed into a flock

 common for a month after that, more being seen along Clear Creek than in 



the foothills. „ • „
