Evening Grosbeak - Female
Evening Grosbeaks are generally monogamous, although when there is an unusually plentiful food supply, polygamy can occur. In most cases, pairs form before the birds arrive on the breeding grounds. Nests are typically located high up in trees, on horizontal branches well out from the trunk or in vertical forks. The female builds the nest, which is a loose saucer of roots and twigs lined with fine grass, moss, rootlets, needles, and lichen.
