“…Of those nest box aggregations, the majority (92%) of observations occurred in high versus 8% low nest boxes. Our results suggest that at times, squirrels are communal during winter months, as was previously documented (Merritt et al, 2001;Dolan and Carter, 1977;Wells-Gosling and Heany, 1984). These researchers observed that during times of food scarcity or cold temperatures, as in winter months, squirrels become communal and form social groups to assist with thermoregulation.…”

Artificial habitat enhancements are important forest structural components that can increase the survival of squirrels (Sciuridae) and thus warrant study. Investigations of squirrel nest box usage can provide useful demographic and community information such as occupancy rates, litter size, habitat preference, species richness and abundance estimates. This artificial nest box study investigated the nesting patterns of squirrels from late winter through early fall 2011 in managed forest stands in Clinton County, New York. Squirrels are sensitive to forest disturbance, hence we compared sites of varying silvicultural activity (e.g., managed for production of timber or maple syrup versus an undisturbed reference stand). A total of 48 nest boxes were constructed and monitored across three separate sites (e.g., reference, logged, and sugaring). Prior research suggested that occupancy may be a function of nest box height (~3.5m and ~5m) and site-specific tree cavity/snags/drey abundance, thus height preference and alternative nesting options were monitored in the survey and analyzed to report detection probability and occupancy estimates in Program Presence. Visual confirmation of northern flying squirrels (Glaucomys sabrinus Shaw) was made in 81%, 44%, and 13% of the nest boxes in the reference, logged, and sugar site, respectively. Approximately 79% of the nest boxes showed evidence of wildlife visitation (e.g., scat, crushed seeds, or nesting material). Additionally, 87% of the high boxes (5m) versus 71% of the low boxes (3.5m) were utilized, and 17% of all occupancies contained multiple individuals. This survey provides additional multi-season occupancy data for an elusive mammal species under managed habitat regimes. We recommend that management plans include a wildlife habitat component that maintains snag trees and live cavity-trees in forest stands. When appropriate, stand management plans could also include installing habitat enhancement structures such as artificial nest boxes for squirrels.

“…Most specimens were found dead in nest boxes, or were accidentally killed during livetrapping procedures in a long-term study conducted by three of the authors. Specimens were identified as northern flying squirrels by their larger relative size and by their gray underbelly pelage (Dolan and Carter, 1977;Wells-Gosling and Heaney, 1984). Identification of all northern flying squirrels, and a sample of the southern flying squirrels, were confirmed with genetic analyses (Garroway et al, 2009).…”

“…The northern flying squirrel is considered a state-endangered species in Pennsylvania, and a subspecies of the northern flying squirrel (G. s. coloratus) is federally endangered in the southern Appalachians. The southern flying squirrel (Glaucomys volans), in contrast, commonly occurs in all wooded habitats and has an eastern distribution south of the Great Lakes that extends up the east coast into southernmost Quebec (Dolan and Carter, 1977). In the midwestern and eastern United States, both species occur marginally sympatrically at a number of locations (Portage County, Wisconsin, Pauli et al, 2004;Ontario, Canada, Garroway et al, 2009), particularly in the Appalachians (North Carolina, Weigl, 2007;Pennsylvania, Mahan et al, 1999).…”

ABSTRACT:There is growing evidence that populations of the northern flying squirrel (Glaucomys sabrinus) are declining in the eastern United States, perhaps due to competition with the southern flying squirrel (Glaucomys volans). Potential causes include parasite-mediated or apparent competition from the shared intestinal nematode, Strongyloides robustus, which has been shown to detrimentally affect the northern flying squirrel but not the southern flying squirrel. To investigate this hypothesis, we conducted a preliminary study on the parasite community of both flying squirrel species from sites in Pennsylvania where the two species occur sympatrically and where G. sabrinus is now considered endangered at the state level. We compared these parasite communities with those from northern flying squirrels from northern New York where the southern flying squirrel is absent. We found eight species of gastrointestinal parasites (Pterygodermatites peromysci, Lemuricola sciuri, Syphacia thompsoni, Syphacia spp., Capillaria spp., Citellinema bifurcatum, Strogyloides robustus, and an unidentifiable cestode species) in both species of flying squirrels examined for our study. The parasite-mediated competition hypothesis was partially supported. For example, in Pennsylvania, S. robustus was overdispersed in southern flying squirrels, such that a small proportion of the hosts carried a large proportion of the worm population. In addition, we found S. robustus to be present in northern flying squirrels when the species were sympatric, but not where southern flying squirrels were absent in New York. However, there was no association between S. robustus and the body condition of flying squirrels. We detected a potential parasite community interaction, as S. robustus abundance was positively associated with P. peromysci.

“…La ardilla voladora (Glaucomys volans) es un animal de hábitos nocturnos, capaz de planear decenas de metros entre los árboles (Dolan & Carter 1977, Ceballos & Manzano 2005. En México se conoce poco sobre la biología de la especie (Ceballos & Manzano 2005, Diersing 1980), lo cual es grave considerando que está catalogada como amenazada según la NOM-059-ECOL-2001 (SEMARNAT 2002) y a nivel internacional con vulnerabilidad especial (Baillie & Groombridge 1996).…”

“…Se ha reportado su presencia en 10 estados del país, en todos ellos, los registros son aislados y están referidos a unas 40 localidades (Ceballos & Manzano 2005). La distribución de la especie en México es disyunta y dispersa (Dolan & Carter 1977) y se considera que ha desaparecido de varias localidades en las que previamente se había registrado. La declinación de sus poblaciones se atribuye a la falta de árboles apropiados para anidar, mismos que han sido sujetos a deforestación (Manzano 1993).…”
