Diet
Most of the evening grosbeak's diet is made up of seeds and fruits, but it also eats insects. It prefers the seeds of maple, spruce, pine, fir, and balsam trees.
The evening grosbeak is a common visitor to bird feeders and is especially fond of sunflower seeds. Life CycleThe female evening grosbeak lays 3-4 eggs in a nest of pine needles, roots, and twigs, and lined with grass, lichen, and moss. The nest is built by the female and is usually placed high in a tree. The female incubates the eggs for 12-14 days. The male brings the female food while she incubates the eggs. Both the male and the female feed the chicks. The chicks fledge when they are around two weeks old, but their parents continue to feed them for a few weeks. Male and female pairs may have two broods a year. BehaviorThe evening grosbeak feeds in noisy flocks. It is a nomadic bird, if the food supply is low in an area, it will move in search of a better location. Some eastern populations migrate south in the winter. Other populations may migrate from high altitudes to lower altitudes. |
