Journal 166 R.E. Johnson 1969 March 17 Fallon, Nevada to Baker, Nevada They had all left. Again unlike the observations of others Mike found the birds were 25% atrata at both Bacchus & Saltair in '67. Several years ago he took some temperature body data of Rosy Finches at the roosts at Bacchus at 8PM & 4AM. He had several quite low Tb's including one around 31° C. This correlates well with my data from the barn in South Park in Colorado. He loaned me this data. We also examined his data on fat scoring (he used 6 classes of fat) as related to snow cover & air temperature. The correlation with snow cover was best but not clear enough to be sure at all. It might take several winters to resolve the matter & there is little chance he can do school and it now that he's out of money working full time at the Fish Hatchery near Baker. He had a letter from Belle indicating that the latter had found an albino rosy finch this winter. Mike had collected a couple atrata - tephroctis hybrids near Saltair [or Bacchus?] & Behle was suggesting they write up these observations for a note.
