western meadowlark distribution

Minneapolis: University of Minnesota Press. Nevertheless, when he examined 66 other BBS routes in the state where Western Meadowlarks had been reported, similar declines were noted statewide. Of particular interest in Minnesota, where the ranges of the Eastern and Western Meadowlark overlap, are differences in habitat use by the two species. “Birding by Hindsight: A Second Look at Second Looks (Part Two).” Loon 82: 138–142. Western Meadowlark (Sturnella neglecta)., North American Bird Conservation Initiative, U.S. Committee. Janssen, Robert B. Years ago, Longley (1955) provided examples of several sites in Minnesota where he found both species, each occupying slightly different habitats. North American Breeding Distribution and Relative Abundance: A decidedly western species, the Western Meadowlark’s breeding range extends across the western two-thirds of the United States and southern Canada, ranging as far east as southern Ontario and Michigan. Western Meadowlark Facts. The North American Breeding Bird Survey, Results and Analysis 1966–2015. “Area Requirements of Grassland Birds: A Regional Perspective.” Auk 118: 24–34. On CRP lands in Minnesota, breeding densities averaged 2.8 meadowlarks per 40 ha (Hanowski 1995). Not only was it abundant throughout the western grasslands, but its breeding range extended east “into the open woodlands quite to the Wisconsin line, avoiding only the heavier forests.” Confirmed nesting records (nests with eggs or young unable to fly) were available from 8 counties stretching from Lyon and Pipestone in the southwest, north to Grant and Otter Tail in west-central Minnesota, and further north to Polk County in the far northwest. The oldest recorded Western Meadowlark was at least 6 years, 6 months old when it was found in Colorado. Further east, in the bluff lands of Winona and Wabasha Counties, he found Western Meadowlarks occupying fields on the flat, open hilltops while Eastern Meadowlarks occupied the more mesic valleys closer to the surrounding deciduous woodlands. Hertzel and Janssen (1998) would later add three more counties to the list. “Area Sensitivity in North American Grassland Birds: Patterns and Processes.” Auk 126: 233–244. Lee, Liling. Breeding distribution and relative abundance of the Western Meadowlark in North America based on the federal Breeding Bird Survey from 2011 to 2015 (Sauer et al. Several years earlier, it was estimated that 0.5% of the North American population occurred in Minnesota (Partners in Flight Science Committee 2013). Minnesota Ornithologists’ Union Occasional Papers, no 2. Several years later, Janssen (1987) described it as rare to absent in Lake and Cook Counties and casual to rare in the north-central region of the state. Although their songs and call notes are nearly always distinguishable, features of their plumage and morphology are challenging if not impossible to separate from one another. Minnesota Prairie Conservation Plan. Unfortunately, in the long term, the impact of warming temperatures on the northern Great Plains is a concern because many species, including the Western Meadowlark, are considered vulnerable to drier conditions and extreme weather events. The breeding habitats of western meadowlarks are grasslands, prairies, pastures, and abandoned fields, all of which may be found across western and central North America, as far south as northern Mexico. Sometimes, however, its territories are not confined to a single tract (Johnson and Igl 2001). There may be more than one … 2006. To the east, confirmed nesting reports were available from Faribault and Martin Counties in the south, north to Morrison County. Aggressive interagency initiatives, such as the Minnesota Prairie Initiative (Minnesota Prairie Plan Working Group 2011), are important efforts to increase the number of grassland acres that are protected and restored throughout western Minnesota. Still broadly distributed across the western United States, the meadowlark’s population decline is one of the principal factors that led to the assignment of a Continental Concern Score of 10/20 (Rosenberg et al. 2016. The Western Meadowlark is the state bird of six states: Kansas, Montana, Nebraska, North Dakota, Oregon, and Wyoming. The results show that the species is encountered in moderate breeding densities along the western tier of counties from Rock and Nobles in the far southwest to Kittson and Roseau in the far northwest. Evidence that the species displays area-sensitivity is mixed. Identification of this species, especially by sight alone, is difficult because it is nearly identical to the Eastern Meadowlark. "height": 425 Summary statistics for the Western Meadowlark observations by breeding status category for all blocks and priority blocks (each 5 km x 5 km) surveyed during the Minnesota Breeding Bird Atlas (2009-2013). 1999. During the MNBBA, participants tallied a total of 1,385 Western Meadowlark records from 17.4% (830/4,774) of the surveyed atlas blocks and 22.6% (528/2,337) of the priority blocks (Figures 2 and 3; Table 1).
