Nancy and Steve Cox of the Rio Grand Research banding team provided this report which includes advice about parking--
On February 3, 2019 we newly banded 33 Rosy-Finches. Twenty-eight were Blacks and five Brown-capped. We recaptured seven Blacks and 3 Brown-capped including a Brown-capped female that was first banded in January 2017. We have now banded 170 Rosy-Finches this season with 85% being Blacks.
The number of Rosies seen today was estimated to be around 135 birds. There are about 100 Blacks, 26 Brown-capped with a few Gray-crowned mixed in.
The upper parking lot is still not plowed and many people are getting stuck. It is advisable to park in the lower parking lot.
