From: Land cover and NDVI are important predictors in habitat selection along migration for the Golden-crowned Sparrow, a temperate-zone migrating songbird

Fig. 4

The relative selection strength (RSS) results for habitat selection along spring migration in 2019–2020 for Golden-crowned Sparrows wintering in northern California. A The RSS for sites depending on the daily maximum temperature (Max Temperature), B The RSS for NDVI, and C the RSS for needleleaf forest habitat at different NDVI values. In panel B, the black line shows the RSS for NDVI in the absence of the habitat types in the model (needleleaf forest and shrubland). The green line shows RSS for NDVI when needleleaf forest is present. Panel C shows the selection strength for needleleaf forest when other habitat types in the model are absent (shrubland) and at minimum, mean, and maximum NDVI values to demonstrate the interaction of needleleaf forest and NDVI. These graphs compare the likelihood of selecting a site compared to another site set at the mean value of the variable (or for panel C, to absence of the habitat type). The logarithmic value of the RSS is zero when the two locations being compared are identical (i.e. RSS = 1); therefore, the dashed line represents “no selection” as it intersects with the mean value (or zero for panel C)
