When the weather is cold and snowy most bird activity is minimal. We did, however, spot a male and female Pine Grosbeak (Pinicola enucleator) eating high up in a cottonwood tree. These birds are usually seen in large flocks, but only two were seen in the tree. They eat mainly seeds, buds and fruit, but will also eat the occasional insect. Pine Grosbeaks will nest in June in an open cup (similar to an American Robin) and will lay 3-4 pale blue eggs with darker dots and markings.
