Late-seasonal Activity and Diet of the Evening Bat (Nycticeius humeralis) in Nebraska

Bats Along the Republican River and Its Tributaries in Southwestern Nebraska: Distribution, Abundance, and Reproduction

“…We captured 69 individuals, including 60 in Red Willow County and 9 in Hitchcock County. These captures represent a westward expansion in the geographic range of this species in the Great Plains ( its westernmost limits in Harlan County (Geluso et al 2008). Our study extends the distribution of evening bats 145 km from the previous westernmost locality in Harlan County.…”

“…The big brown bat commonly is observed in buildings, is a year-round resident, and occurs throughout Nebraska (Czaplewski et al 1979). Despite its abundance in former surveys across the state (Czaplewski et al 1979, Geluso et al 2004b, Benedict 2004 Geluso et al (2008); the triangle represents a recent record in Kansas (Phelps et al 2008); and closed circles represent new records presented in this study. The shaded region represents our proposed distribution of N. humeralis in Nebraska and Kansas.…”

“…By altering flow regimes with the construction of dams, the density of trees has increased in floodplains, in part because of lack of spring ice jams that once scoured woody vegetation along banks of rivers. In the Great Plains, woodland species of mammals generally associated with eastern deciduous forests, including evening bats and eastern pipistrelles (Perimyotis subflavus), have shifted distributions westward reflecting ecological changes to riverine habitats (e.g., Wilson and Choate 1996, Benedict et al 2000, Sparks and Choate 2000, Geluso 2004, Roehrs and Genoways 2004, Geluso et al 2008.…”

Westward Expansion of the Evening Bat (Nycticeius humeralis) in the United States, with Notes on the First Record from New Mexico

“…1). Numerous sites within the newly expanded distribution yielded multiple captures of volant young and reproductive females (Dowler et al 1999, Sparks and Choate 2000, Lane et al 2003, Geluso et al 2008, Serbousek and Geluso 2009, Johnson and Geluso 2017. We suspect that this species will continue to expand its distribution and increase in abundance through out the Great Plains.…”

Observations on the Distribution and Status of Selected Nebraska Mammals

“…We document here a twentieth county-Richardsonin extreme southeastern Nebraska to the places where evening bats are known, although Brack et al (2019) recorded the species from the county based on capture/release specimens. Evening bats are migratory in Nebraska, with the earliest arrival date reported being 30 April (Serbousek and Geluso 2009) and the latest date present being 6 October (Geluso et al 2008). The Nebraska populations consist solely of adult females and flying young of the year after 23 June (Serbousek and Geluso 2009).…”
