We developed predictive models of pup-rearing habitat (i.e., den and rendezvous sites) that could help guide future population monitoring efforts of Mexican wolves. Mexican wolves selected den sites at higher elevations in steeper and rougher terrain that was closer to permanent waterbodies but farther from rural roads, whereas selection of rendezvous sites was associated with higher elevations and proximity to waterbodies but varied with availability of green leaf biomass. Terrain features associated with physical protection and access to reliable water were most important in characterizing suitable pup-rearing habitat for Mexican wolves.

The American Woodcock Singing-Ground Survey (SGS) may not cover all available woodcock breeding range, particularly in more northern regions. Using SGS data collected in Canada between 2000 and 2019, we evaluated the relationship between 16 landscape covariates and male woodcock occurrence and abundance and we developed a predictive map to identify priority areas for SGS expansion in Canada. We found that male woodcock prefer moist areas with young, broadleaf forest intermixed with pasture and grassland clearings for display. We also identified sites north and west of the current SGS range for possible SGS expansion.

The isolated and endangered Columbian population of fishers (Pekania pennanti) is thought to be declining in central interior British Columbia (BC), Canada, yet still little is known about the distribution and abundance of the species in several regions. The density of fishers in the Chilcotin study area west of Williams Lake was among the highest ever reported for the province (21.3 ± 3.8 SE fishers/1,000 km²), whereas density in the Enterprise study area southeast of Williams Lake was among the lowest (8.9 ± 2.7 SE fishers/1,000 km²). Density estimates for both study areas, however, were orders of magnitude lower than those reported for eastern North America and the western United States and thus are at levels worthy of concern.
