Further Extension of the Range of the Northern Pygmy Mouse, Baiomys taylori, in Southwestern Oklahoma

Rodents New to the Diet of the Western Burrowing Owl (Athene cunicularia hypugaea)

“…The northern limit of the range of the northern pygmy mouse was restricted to southern and southeastern Texas in the 1950s (Nowak, 1999), but since the 1980s, this species has extended its range into northern and western Texas, including the southern Panhandle (Choate et al, 1990), southern Oklahoma (Stangl et al, 1992;Stuart and Scott, 1992;McDonald et al, 2006), and New Mexico (Tumlison et al, 1993). New distributional records have been recorded also for the fulvous harvest mouse in northern Texas (Goetze et al, 1995;Smith et al, 1998) and western Oklahoma (Wallace and Stangl, 2003;Braun and Revelez, 2005;McDonald et al, 2006).…”

Comparative Diet Analysis of Barn Owl (Tyto Alba) and Long- Eared Owl (Asio Otus) in a Habitat Island in North-Central Texas

“…In particular, interactions between migratory and resident raptors in Texas, one of the main migratory routes of birds, have been scarcely studied. Likewise, little is known about the prey populations of vertebrate predators in northern Texas (Dalquest 1968;Schmidly & Bradley 2016) beyond their presence and the fact that they are changing in distribution (Hunsaker et al 1959;Hart 1972;Austin & Kitchens 1986;Cleveland 1986;Tumlison et al 1993;Green & Wilkins 2010), population dynamics (Wilkins 1995), and habitat relationships (Hanchey & Wilkins 1998). In this study, we examined the diet of two owl species, the barn owl (Tyto alba) and the long-eared owl (Asio otus), in a protected habitat island of vegetation in the Dallas-Fort Worth Metropolitan (DFW) area and compared their winter trophic ecology through remains found in pellets.…”
