Carolina Wren,Thryothorus ludovicianus.
Common permanent resident. The population is affected by winter weather, with
decimations occurring during severe cold and expansions during mild winters. These
population trends are reflected in results from the Fayetteville Christmas Bird Count
where lows of single birds (1978, 1979) contrast with highs of 52 (1976) and 69
(1982).
Bewick's Wren,Thryomanes bewickii.
Fairly common migrant in small numbers, very uncommon summer resident; once a
permanent resident in the region. Spring migrants appear in March and
seem to linger into May; fall migrants are reported between late September
and early December. Black (1935) considered the species an irregular
summer resident at Winslow. Baerg (1951) considered it "locally common" in
summer at Fayetteville. There have been no reports on the Fayetteville
Christmas Bird Count since the early 1970's. During the 1984 and 1985
breeding seasons, the bird was found near Rogers in a country yard full
of junk cars and deteriorating sheds. A special effort to find these birds
in 1986 resulted in reports of adults with young on Mt. Sequoyah in
Fayetteville and at Bob Kidd Lake. There were also at least five other
locations with singing birds in Washington and Benton Counties. It
appears Bewick's Wren still occurs in summer in the region in a few
scattered places. Young fledged from a nest in a gourd between
Springdale and Rogers on June 19, 1988.
