Nancy Cox of Rio Grande Bird Research provided a recap of the 2017-18 winter banding season at Sandia Crest House. Included is a link which provides the numbers and species mix over the years:
We had two returning Black Rosy-Finches (one male, one female) that were originally banded in the winter season 2010/2011. We had another 4 Blacks (three males and one female) return from January 2015. Those were our oldest returning birds but we also had two birds (Brown-capped and Gray-crowned interior both females) who were already adults when we first banded them in November 2015...

...We banded 159 total Rosy-Finches this season for a grand total of 3090 birds for the project. Blacks accounted for 67% this season and 50% for all seasons.
I went up on April 2 and saw only 10 Rosy-Finches. I have not seen any eBird checklists showing Rosy-Finches for the Crest since then. We did get a dusting of snow early today [APR 13] and it is very windy.
