Red-shouldered Hawk (Buteo lineatus)


Overview

Overview


Red-shouldered Hawk (Buteo lineatus), a bird listed as Threatened in Wisconsin. This species prefers larger stands of older-aged to mature bottomland hardwoods along riparian areas, deciduous swamps, and northern hardwoods or mixed deciduous – coniferous upland forests with wetland pockets or ephemeral ponds interspersed or located in close proximity. The recommended avoidance period is from March 15 to July 31 in southern Wisconsin, and April 1 to July 31 north of Highway 64. See the species guidance document for avoidance measures and management guidance from the Natural Heritage Conservation Program.

Native community (habitat) associations

The table below lists the natural communities that are associated with Red-shouldered Hawk. Only natural communities for which Red-shouldered Hawk is "significantly" (score=3) or "moderately" (score=2) associated are shown. Please see the Wildlife Action Plan to learn how this information was developed.

Ecological landscape associations

The table below lists the ecological landscape association scores for Red-shouldered Hawk. The scores correspond to the map (3=High, 2=Moderate, 1=Low, 0=None). For more information, please see the Wildlife Action Plan.

This map shows the probability of Red-shouldered Hawk occurring in each of Wisconsin's Ecological Landscapes.  Actual scores can be found in the table to the left.

Landscape-Community combinations of highest ecological priority*

Ecological priorities are the combinations of natural communities and ecological landscapes that provide Wisconsin's best opportunities to conserve important habitats for a given Species of Greatest Conservation Need. The 10 highest scoring combinations are considered ecological priorities and are listed below. More than 10 combinations are listed if multiple combinations tied for 10th place. For more information, please see the Wildlife Action Plan.


* Ecological priority score is a relative measure that is not meant for comparison between species. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.

Conservation actions

  • Designating Red-shoulder Hawk nesting territories is recommended where and when appropriate. Bryant (1986) recommends leaving an uncut buffer zone around traditional Red-shouldered Hawk nests to discourage Red-tailed Hawks.
  • Research is needed to evaluate how Red-shouldered Hawks respond to different management regimes.
  • This area-sensitive species benefits from maintenance of large blocks of relatively undisturbed, mature mixed riparian woods and mature upland deciduous woods (with a preference for bottomlands and wooded margins adjacent to marshes) where at least 70% or

Threats and issues

  • One of several raptors adversely affected by organohalogens.
  • Hydrological alterations due to dams may be a long-term detriment to the health of floodplain forests and thus be a threat to Red-shouldered Hawk habitat.
  • Loss and fragmentation of large blocks of forest, particularly riparian forests.
  • A reduction in forest canopy cover, or removal of nesting trees, can be detrimental to this species. Red-tailed Hawks can outcompete Red-shouldered Hawks in forests with parially open canopies.
  • Human use of forest roads and trails near nest sites during the breeding and nesting seasons may disturb Red-shouldered Hawks and cause them to abandon nests and possibly territories.
  • Invasive plants such as reed canary grass or buckthorn are a threat to the long-term health of the floodplain forest systems.
