Correction: Long-term winter food supplementation shows no significant impact on reproductive performance in Mountain Chickadees in the Sierra Nevada Mountains

This is a correction to: Benjamin R Sonnenberg and others, Long-term winter food supplementation shows no significant impact on reproductive performance in Mountain Chickadees in the Sierra Nevada Mountains, Ornithology, Volume 140, Issue 1, 12 January 2023, ukac051, https://doi.org/10.1093/ornithology/ukac051 In the originally published version of this manuscript, Table 1 was lacking details in the first section, ‘First egg date’. The Table should read: TABLE 1. Analysis of deviance table showing whether winter feeding influenced multiple breeding variables for mountain chickadees at high and low elevation sites. Models were run separately for each breeding variable and each elevation. Type II Wald chi-square (χ2) tests are reported for the parent access to feeders fixed effect in each model. Degrees of freedom for each χ2 value is 3. ∆R2 represents the change in the marginal R2 value when the parent access to feeders fixed effect was removed from the model. Full results for each model can be found in the Supplementary materials.
