Abstract Habitat and landscape features that influence the rate of interpatch movement and colonization may determine the likelihood that a species will persist in fragmented landscapes. We simulated patch extinction by removing Carolina Chickadees (Poecile carolinensis) from woodland fragments in an Ohio agricultural landscape in January 2002. We then monitored the woodlands to determine their dates of reoccupation and subsequent use for breeding by the birds. All woodlots were eventually reoccupied, regardless of size or degree of isolation, but woodlots in less-forested landscapes connected to other woodland by habitat corridors were reoccupied sooner than unconnected woodlots. Reoccupation was more likely to occur during periods of mild wind chill. Following reoccupation, individual Carolina Chickadees were more often temporarily absent from smaller woodlots, which suggests that they may have used woodlots that insufficiently met foraging or breeding requirements. Carolina Chickadees were more likely to remain to breed in larger woodlots. Results indicate that habitat connectivity may affect the tendency of this species to move through a fragmented landscape. Habitat corridors may be important management tools for maintaining movement of animals between patches.

AbstractWe tested the “peak-demand” and “reallocation” hypotheses of seasonal energy expenditure which predict, respectively, that energy expenditure is greatest during the breeding season or varies little seasonally. We tested these predictions by utilizing the doubly labeled water technique to estimate energy expenditure and water flux of Carolina Chickadees (Poecile carolinensis) in both the breeding and nonbreeding seasons. Similar to Weathers et al. (1999), we did not find support for either of these hypotheses, finding instead that energy expenditure was greater during the nonbreeding season. The fact that our study site was at the northern edge of the species' range, where winters are severe, may have influenced this result. Comparisons with other parid studies were equivocal because body size was an important factor in explaining seasonal energetics, and only the larger species have been examined during the breeding season.
