“…Mouse predation was also linked to low tree densities, low litter accumulations, and high shrub densities, corresponding to habitat used by mice in artificial-nest and population studies (Leimgruber et al 1994;Carey and Johnson 1995). In contrast to results from other studies (Drickamer 1990;, we found that mice did not visit nests in areas with large amounts of woody debris (Table 1), which provide nesting and protective cover, foraging sites, and travel lanes (Wolff and Hurlbutt 1982;Carey and Johnson 1995).…”

Vegetation characteristics are commonly invoked to explain differential nesting success, but few studies have identified how habitat attributes may be associated with specific predator groups responsible for nest losses. We measured vegetation characteristics at artificial songbird nests deployed on and above the ground in mixedwood forest in west-central Alberta, to discriminate characteristics of successful nests from those of nests destroyed by mice and voles, squirrels, and birds. Successful nests, and those depredated by mice and voles, tended to be on the ground and were well concealed by dense shrubs. Squirrels and birds usually raided aboveground nests at sites with few shrubs and high tree densities. These results suggest that nest visibility is a major factor influencing risk of predation, but the relative importance of concealment varies according to the types of predators and their behavior. The characteristics of nests from which eggs were removed, leaving no egg remains to identify predators, closely resembled those of nests visited by squirrels and birds. Our findings have implications for how individual songbird species cope with selection pressures imposed by nest predators associated with vegetation characteristics of birds' nest patches and, ultimately, how predators may shape the structure of avian communities.Résumé : Les caractéristiques de la végétation sont souvent évoquées pour expliquer les fluctuations du succès de la nidification, mais peu d'études ont tenté de déterminer comment les attributs d'un habitat peuvent être associés à des groupes spécifiques de prédateurs responsables des pertes au nid. Nous avons mesuré les caractéistiques de la végétation près de nids artificiels de passereaux installés sur le sol et au-dessus du sol dans une forêt mixte du centreouest de l'Alberta, afin de déterminer lesquelles de ces caractéistiques sont reliées aux nids réussis par opposition aux nids détruits par les souris et campagnols, les écureuils et les oiseaux. Les nids réussis et ceux pillés par les souris et campagnols sont des nids au sol, bien camouflés par des buissons denses. Les écureuils et les oiseaux pillent généralement les nids au-dessus du sol à des sites où il y a peu de végétation et où les arbres sont denses. Ces résultats semblent indiquer que la visibilité du nid est un facteur très important de risque de prédation, mais l'importance relative du camouflage varie selon le type de prédateur et selon son comportement. Les caractéistiques des nids pillés où il n'est resté aucun débris permettant d'identifier le prédateur ressemblaient fortement à celles des nids pillés par les écureuils et les oiseaux. Nos résultats soulèvent le problème de l'adaptation des passereaux aux pressions de sélection qui sont créées par les prédateurs de nids et qui sont associées aux caractéristiques de la végétation dans l'entourage des nids et, ultimement, nous amènent à nous demander comment les prédateurs peuvent influencer la structure des communautés d'oiseaux.[Traduit par la Rédaction] Rangen et...

“…Communal nesting of opposite sexes has been demonstrated for P. leucopus during the nonbreeding season (Nicholson 1941;Wolff and Hurlbutt 1982;Madison et al 1984), but communal nesting during breeding seasons is rare (Madison 1977;Mineau and Madison 1977; but see Wolff and Hurlbutt 1982). Although we have no direct evidence that the male P. californicus was actually caring for the young, the presence of the male in the nest while the lactating female was absent strongly suggests that the male was caring for the young at least some of the time.…”

Home ranges, social organization, and nest co-occupancy of Peromyscus californicus were studied using radiotelemetry at the Hastings Natural History Reservation, California. Mated pairs were ascertained by the transfer of fluorescent pigments from lactating females to putative fathers. Mated pairs had largely overlapping home ranges that were not statistically distinguishable, whereas adjacent adults had mostly exclusive, statistically distinguishable home ranges. There was no difference in the mean home range of males and females, but mated females tended to have smaller ranges than their mate. Home range size was extremely variable (range: 150-3788m 2) and averaged 1161 m 2 across all individuals. Male home range size was inversely correlated with population density, suggestive of a social influence on home range. Putative fathers spent comparable amounts of time to females in the nest -presumably caring for the young -which supports previous laboratory reports of paternal care in this species. All data collected in this study are consistent with previous suggestions that P. californicus live in semi-permanent family groups and are monogamous.

“…It is difficult to explain the effect of thinning in our study because of the differential habitat use exhibited by species in this genus. The deermouse, Peromyscus maniculatus nubiterae, and white-footed mouse, Peromyscus leucopus novaborancensis are sympatric in forest habitats of Appalachia (Wilson, 1945;Klein, 1960;Wolff and Hurlbutt, 1982;Barry et al, 1984;Buckner and Shure, 1985) and occur in a wide range of habitat types. Both species have been captured and have shown microhabitat separation in the study area (Violet, 1973;Bardwell, 1979).…”
