172 Journal R.E.Johnson 1969 March 20 Boulder & Nederland & vicinity to Denver, Colorado might that the presence of Starlings may prevent the presence of Rosy Finches. This lady said both that the Starlings had been here about a wk & that she hadn't seen Rosy Finches in about a week. I had wondered about this sort of mutual exclusion as I drove back from Colorado on my last trip where it seemed I never found rosy finches at dumps, where there were Starlings. or rancbes However I only saw Rosy Finches at 2 or 3 dumps & there were other bird species involved also, so that I felt I lacked enough data to draw any conclusion or even form Kathy's hypothesis. It's beginning to look more likely now. Next I visited site #3 at about noon. There were no birds present then but Mrs. Snarely said that they occur off & on all day & that all she has to do is pour more food out & the birds would show up. She then put food out & within 10 minutes there were 50 birds there. The birds came & went but it was clear that most groups were 8 or 10 to 1 of tephrocotis over littoralis. In the last group there were several brownies. She is anxious to help me catch some birds & will get up at 5:30am to let me in & help set up traps &/or nets for that purpose! Her husband is the local minister (Presbyterian). She said the birds first arrive in mid-January. They also have Pygmy Nuthatches (I saw 3), Stellers Jays, Clark's Nuthatchers, Mt'n Chickadees & occasional WB. Nuthatches. Next I drove south to Rollinsville & W. to Tolland & East
