Is meadowlark habitat segregation within sympatry behaviorally mediated?
The Eastern Meadowlark (Sturnella magna) and Western Meadowlark (Sturnella neglecta) are morphologically and ecologically similar species that co-occur within a recently expanded zone of secondary contact. Although spatial patterns of sympatric meadowlark populations have been previously compared, …

Behavioural, mensural, and ecological correlates of polygyny in the eastern meadowlark (Sturnella magna)
… and attributes of the territory of male Eastern Meadowlarks (Sturnella magna) in order to determine whether there was a correlation between any of the attributes investigated and the number of females attracted by a male. Seventeen males, nine of which were polygynous and eight monogamous, were …

Strategic Concessions: Negotiating Human Land Use to Serve the Habitat Needs of the Eastern Meadowlark
… satisfies habitat requirements for the Eastern Meadowlark. Through analysis of storm water volumes, building code setbacks regarding waterways, habitat requirements of the Eastern Meadowlark and land volume manipulation, a solution to many obstacles facing community and species has been posited …

A myological and osteological comparison of the pelvic appendage of the male and female western meadowlark
<p>Sexual dimorphism has been noted to exist in many genera of birds, but it is not until recently that papers have appeared which deal with the actual extent of sexual dimorphism and its possible adaptive significance. The papers of Rand (1952), Sibley (1957), Amadon (1959), and Selander (1966) …

The Effects of natural Gas Development on Density, Reproductive Success and Nest Survival of Grassland Songbirds in South-Western Saskatchewan
… Horned Lark (Eremophila alpestris) and Western Meadowlark (Sturnella neglecta). I quantified and compared aspects of their breeding biology with published data in other parts of their range. Reproductive rates were typical of those found elsewhere. Time-specific variables (age and date) were …

Modeling Detection and Density Using Distance Sampling for Three Priority Grassland Bird Species in Texas - Northern Bobwhite (Colinus virginianus), Eastern Meadowlark (Sturnella magna), and Painted Bunting (Passerina ciris)
… Northern Bobwhite (Colinus virginianus), Eastern Meadowlark (Sturnella magna), and Painted Bunting (Passerina ciris). Due to this, accurate density and abundance estimates are critical for management of these species. This 5-year study identified covariates that influence detection, availability …

Passerine Use of Grasslands Managed With Two Grazing Regimes on the Missouri Coteau in North Dakota
… Savannah sparrow, grasshopper sparrow, western meadowlark, bobolink, and Baird's sparrow all have been previously cited as being negatively affected from grazing. These grassland birds were grouped into a grazing sensitive guild, which had a higher mean relative abundance on rotational grazing …

Nesting Success of Grassland Birds in Fragmented and Unfragmented Landscapes of North Central South Dakota
… longspur (Calcarius ornotus ); western meadowlark (Sturnella neglecta); grasshopper sparrow (Ammodramus savannarum); savannah sparrow (Passerculus sandwichensis); ringnecked pheasant (Phasianus colchicus); and dabbling ducks (Anas spp.). Response to landscape and patch variables varied …

Using Occupancy Models to Predict Grassland Bird Distributions in Southeastern Alberta
… Vesper Sparrow (Pooecetes gramineus), Western Meadowlark (Sturnella neglecta), and Willet (Tringa semipalmata). Models that best explained detectability typically included both date and time of day of the survey. The amount of grassland on the landscape was a broadly useful measure in …

Grassland bird associations in a managed agricultural matrix
… but other abundant species included Eastern Meadowlark, Indigo Bunting, Mourning Dove, and Northern Bobwhite. Bird diversity was greater in blocks than buffers, and diverse filter strips had the greatest bird densities. I found and monitored large samples of Dickcissel (n = 733) and …

EFFECTS OF SCALE AND HABITAT MANAGEMENT ON GRASSLAND BIRD RESPONSE IN CONSERVATION RESERVE PROGRAM FIELDS IN NORTHWEST ILLINOIS
… sparrow (Ammodramus henslowii), eastern meadowlark (Sturnella magna), field sparrow (Spizella pusilla), and northern bobwhites (Colinus virginianus), due to the release of tall forbs within the seed bank after spraying brome dominated fields. Dramatic vegetation responses in sprayed brome …
