Six years ago in late August, Rich Levad, Rob Sparks, Jason Beason and Ken Behrens hiked through spruce fir forest to a spot just above timberline where a Black Swift nest clung to a wet, rocky outcrop. The outing was part of Rocky Mountain Bird Observatory’s effort to collect baseline data on this little-known species. When no swifts were seen that evening, the scientists wondered if they had already started migrating – and where did they go?
The last bird that breeds in the U.S. and Canada with an unknown winter destination has finally given up its secret. After years of research – and with some luck – three Colorado researchers have learned that Black Swifts travel more than 4,000 miles to spend the winter in Brazil.
Rocky Mountain Bird Observatory will sponsor the Barr Lake Christmas Bird Count (CBC) on January 2, one of 48 CBC circles being surveyed in Colorado during the holiday season. The count is open to birders of all skill levels. Last year in the Barr Lake circle, 21 volunteers counted 27,446 birds of 63 species.
