Participants were asked to estimate the abundance of wild foods in their postal code. Wild foods were: cones, berries, and seeds. Individuals could rate the abundance of each wild food  as heavy, moderate, or low. Only reports with estimates of wild food abundance were used to generate the maps.

Greater than 52% of all Pine Grosbeak reports came from areas where the berry crop abundance was either moderate or heavy.

The pie chart shows what Pine Grosbeaks were feeding on when not at bird feeders.
