BIRDS OF CONCERN

The Birds of Concern in the Chicago Wilderness (CW) region is a list of species needing priority attention and management. This BOC list was developed using regional lists of species of concern in the Partners in Flight (PIF) Species Assessment Database (2020). The CW region is on the edge of two PIF Bird Conservation Regions, BCR 22 and 23. PIF priority levels from both BCRs were adjusted using population trends, distribution, threats, and breeding success data for the CW region. The migrants list was created by evaluating PIF scores in regions north of the CW area. A number of listed species not ranked by PIF are from other data sources including the Upper Mississippi River & Great Lakes Joint Venture's Habitat Strategies for Shorebirds, Waterfowl and Waterbirds, and endangered and threatened species from: IL, IN, WI, & MI. To request more information, please Contact BCN.

For additional details about the methods used to produce the list below, please read the full Review Process (coming soon).

			HIGHEST CONCERN. Priority Management Needed. Species having high regional threats, experiencing large population declines, and/or with highly regionally concentrated populations. Conservation action needed.
			HIGH CONCERN. Species experiencing moderate to strong declines, threats to breeding, and/or with moderately regionally concentrated populations. Management or other actions needed to stabilize/increase populations or reverse threats.
			MODERATE CONCERN. Require management and monitoring, especially for species with declines or threatened and endangered populations. Includes certain species more widespread outside of Chicagoland plus species using only limited/localized habitats.
			Rare or Recently Extirpated. A species not of regional importance in the Midwest, but threatened or endangered in at least one of the states in the Chicago Wilderness Region.
	Frequency		% of all BCN Survey points where the species was detected at least once. A gauge of how common or uncommon a species is in the CW region. The dots are a visual key to that relative abundance.
	Additional Statuses		State-E: State Endangered; State-T: State Threatened; State-SC: State Species of Concern; BCC: USFWS Breeding Bird of Concern; PIF-#: Adjusted Partners in Flight score of 14 or higher.
