Birds of Kansas Streamside Forests Nature’s Winged Legacy Birds that inhabit forests in eastern Kansas include: Eastern Kansas hosts a variety of bird life. Much of it Hairy Woodpecker can be found along the forested waterways that connect the Pileated Woodpecker tallgrass prairie, crop fields, and towns. More than 100 bird Broad-winged Hawk species use the streamside forests and other woodlands in Red-shouldered Hawk Riley County alone. Birds depend on these riparian forests for nesting and raising young, as stopover habitat during Barred Owl migration, or a winter haven. Wood Duck Wood Thrush Landowners and managers play an important Yellow-throated Vireo role in conserving nature’s winged legacy. This Scarlet Tanager publication describes features of streamside forests that are important to particular species of Red-eyed Vireo birds.

The following information is provided Eastern Whip-poor-will to help landowners determine how well their streamside forests benefit birds and to find support for habitat Forest Age and Condition restoration and improvement projects. Mature forests with full-size, seed- and fruit-producing trees are important to some species, usually for adequate Forest Size and Continuity food supply, nesting sites, and cover. Species associated with Birds may prefer or require forest tracts of 50 acres mature forests: or more. Large-bodied forest birds such as the Red- Wood Duck shouldered Hawk and Pileated Woodpecker need a Red-shouldered Hawk large territory for foraging. Song birds such as the Red- eyed Vireo, Ovenbird, and Kentucky Warbler need the Barred Owl protection of the inner forest. For the Wood Duck, Eastern Hairy Woodpecker Whip-poor-will, and Barred Owl, continuous stretches of Pileated Woodpecker woodland may be more important than forest patch size.

These cavities provide nesting sites, not only particularly when breeding and nesting: for the woodpeckers, but also for many other birds known Chuck-will’s-widow as secondary cavity nesters. Eastern Bluebirds are secondary Eastern Whip-poor-will cavity nesters of fields and woodland edges. Osprey and Great Blue Heron Bald Eagle use tall, dead trees as hunting perches. Black-crowned Night-heron Turkey Vulture Bald Eagle Cooper’s Hawk 2 Red-shouldered Hawk White-eyed Vireo, and Bewick’s Wren, require low, dense Yellow-throated Vireo vegetation for nesting and protection from natural enemies.
