Mitchell SD 2017 Christmas Bird Count Results

About the Audubon CBC

For over 100 years, the Audubon Christmas Bird Count (CBC) uses volunteers to track bird populations by holding local counts across North and South America. The Mitchell Count, one of about 2,500, involved volunteers of all birding levels to count birds in the field and at their feeders.

About the Mitchell CBC

The Mitchell CBC was reinitiated in 2013 after a 46 year hiatus. This was our fifth consecutive year to hold the count.  The count occurred on December 26 with 17 field observers and 4 feeder watchers.  All birds were counted within the count circle. The circle is centered in Mitchell and is 15 miles in diameter.

The Audubon map of the count circle can be found at https://arcg.is/0mDr0W.


Count Summary

After unseasonably mild temperatures, the days preceding the count had below zero temperatures that froze all water. On the day of the count we had clear skies and little wind. Day time temperatures started at -13 F and only rose to 2 F.  There was 4 inches of snow on the ground. There was no open water. A total of 23 people participated. We had 7 groups of people who birded in the field but only 4 groups that watched their feeders.  Some of our regular participants were out of town for the holidays.

We had a total of 5,552 birds counted composed of 44 species and 3 subspecies for the count. There were 2 count week species. The most abundantly seen bird was the red-winged blackbird.

One new species was added to the count, a white-winged crossbill.  It was seen at a feeder, proving the fact that feeder watchers are vital to a successful count.

We had high counts for rock pigeons, house finch, and common redpolls as well as Oregon dark-eyed junco.

Our best birds were the greater prairie-chicken, yellow-rumped warbler, and of course white-winged crossbill.

Some species that are normally seen but missed include mallard, mourning dove, brown creeper, golden-crowned kinglet, snow bunting, western meadowlark, and common grackle.

I’ve composed two tables.  One has counts for this year and the other displays data from all count years.

I think it’s interesting to compare this year to previous years. Zero denotes count week species.
