The Cornell Laboratory of Ornithology provided an excellent description of this secretive wetland sparrow, “A richly colored sparrow with a saffron-yellow eyebrow and whisker marks framing a grayish cheek. The interior-breeding form of Nelson’s Sparrow, this yellow color continues strongly onto the throat, breast, and sides, with streaking on the breast and flanks.”
Steve Theissen from Stoughton is one of Wisconsin’s best in locating fall migrating Nelson’s sparrows. This sparrow is difficult to find in migration. In addition to knowing the identification you also have to know their fall migration habitat.
Steve wrote on October 9th that, “Jim Otto had mentioned large numbers of pine siskins in the prairies at Goose Pond. I walked some of Browne Prairie and was treated to a few large flocks of siskins. As usual, I headed for sparrow habitat. I was trying to see a probable Nelson’s sparrow, which flew, and I happened to check out a song sparrow. In the same bush there were two Nelson’s. Besides these two, I’d say there were three more small sparrows in the area. There were lots of savannah, song and swamp sparrows. This area would have a lot easier viewing, early, with low winds. Quite windy, today.”
Other birders reporting Nelson’s sparrows were Deb Turski (2 on Oct. 10th), Cicero Stewart (2 on Oct. 11), Aaron Holschbach (4 on Oct. 18th), Logan Carlton (1 on Oct. 18), and Tim Fenske (1 on Oct. 21). Nelson’s sparrows were on the 1978 Goose Pond Bird List. While Steve’s Nelson’s sparrow observations were the first ever reported at Goose Pond on eBird.
There were other sparrow species found in the same area. On October 10th, Mike McDowell found one LeConte’s sparrow, a first eBird entry for Goose Pond. Also reported on eBird were 44 savannah sparrows (high count for Goose Pond), 18 song sparrows, and 38 swamp sparrows reported by Aaron Holschbach. Mike also found two Lincoln’s sparrows and Dennis Casper also reported two on October 20th. All the sparrows were feasting on seeds in this diverse habitat.
