    Grosbeaks are birds characterized by solid and thick beaks useful when grinding seeds and nuts. Being part of the Passerellidae family, there are different types of grosbeaks in North America, and here they are with details on their performances and behaviors. 

    In this article, readers will be able to learn in detail about ten grosbeak species in the United States, including their scientific names, habitat, migration, appearance, external characteristics of the beak/feathers, feeding behavior, nesting, mating, breeding period, eggs, and young birds' descriptions.

    Evening Grosbeak 

    Evening Grosbeak



    Scientific name:
    Coccothraustes vespertinus

    Habitat: Their origin or habitat is coniferous forests, mixed woods, and urban settings. The meal is sought in areas with many fruiting trees and shrubs.

    Migration: These birds are partly migratory and partly resident. Young birds attain the status of migration after one year. While the latter penetrate their breeding grounds, some of their populations move southward depending on food availability.

    Appearance: The Evening Grosbeak-sized bird is beautifully built with a thick, stocky frame and a thicker beak. Males are bright yellow and have black wings and a black crown, while females are less colorful and have yellowish-brown plumage color with black wings.

    Beak: Its beak is big and made conical to break seeds, which are its main diet.

    Feathers: It mainly covers areas with bright yellow plumage complemented by black and white wings or from head to tail.

    Feeding Habits: The Evening Grosbeaks naturally feed on seeds, mostly from coniferous trees, fruits, and berries. That's why they are reported to feed in groups called foraging flocks.

    Nesting: These birds make bowl-shaped nests in trees, which may be about 10 to 30 feet from the ground, using soft materials such as twigs, grasses, and plant fiber.

    Mating Behaviors: The males do serialization and feed the female's eggs. During the breeding period, they are known to be monogamous.

    Breeding Season: It breeds between May and July, although some months may begin from early June.

    What does its egg-like: Their eggs are, thus, pale blue to greenish and marked with some darker spotting.
