    Veery Life History

    Habitat

    Habitat ForestsVeeries breed in dense, damp, mostly deciduous woodlands, often near rivers, streams, and swampy areas. Breeding habitat includes forests of oak, maple, cherry, aspen, birch, alder, spruce and fir, among other trees and shrubs. Veeries gravitate toward disturbed forests, where dense understory provides protected nest sites. During spring and fall migration, they favor forest edges and second-growth woodlands. Back to top

    Food

    Food InsectsVeeries eat mostly insects and other invertebrates during the breeding season; mostly fruit in late summer and fall. Prey include beetles, ants, wasps, caterpillars, grasshoppers, flies, bugs, and occasionally small frogs and salamanders. Fruits in the diet include juneberries, honeysuckle, strawberries, blackberries, wild cherries, sumac and dogwood fruits, blueberries, wild grapes, and elderberries. Back to top

    Nesting

    Nest Placement

    Nest GroundVeeries usually build their nests on or near the ground, rarely higher than 5 feet up. The nest may rest in a clump of grass or other soft vegetation, on a mossy hummock, under brush and debris, or against a fallen trunk or branch. Some nests are found on high, dry hillsides.

    Nest Description

    The female constructs the cup-shaped nest over a period of 6–10 days while her mate guards the territory. She begins by creating a platform of dead leaves, to which she adds grapevine bark, weed stems, and wet, decomposed leaves. She lines the nest with rootlets and other fine fibers, continually shifting her position as she presses the material down to shape the nest evenly. The finished nest has an outside diameter of about 3-6 inches and an outside height of about 3.5-5.5 inches; inside, it’s about 2-3 inches in diameter and 1- 2.5 inches deep.

    Behavior

    Behavior Ground ForagerVeeries forage mostly on the ground—moving in a rapid series of long hops; sometimes flipping over leaf litter with their bills to catch creatures hiding underneath. They also search through understory foliage, hunt from rock or log perches, and occasionally catch insects on the wing. They are strong, fast fliers that make quick trips between protected perches when necessary. Males arrive first on breeding grounds and begin defending territory against other males. They’re initially aggressive toward females as well, but after 3–4 days this transitions to courtship flights, culminating in bonding and mating. Rival males fight by raising their bills and snapping them forward, quivering a foot, freezing for a couple of seconds in an erect pose, and flicking wings and tail. Back to top

    Conservation

    Conservation Low ConcernThough still common in northern woods, Veeries have experienced slow, but significant declines over the last half-century. Overall, between 1966 and 2014, populations declined by 42%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 11 million, with 68% breeding in Canada and 32% breeding and migrating through the U.S. The species rates an 11 out of 20 on the Continental Concern Score. veery is not on the 2014 State of the Birds Watch List. Possible causes of their decline may include the extremely rapid transformation of South American forests (winter habitat) to agricultural land. Some of the bird’s northern woodland breeding habitats are also being destroyed or fragmented—a process that not only diminishes breeding opportunities but also increases nest parasitism by Brown-headed Cowbirds. Clearing of the dense understory that Veeries prefer—along with increased understory browsing by growing populations of white-tailed deer—may also be detrimental.Back to top
