High variability of migration strategies in a re-established Cygnus buccinator (Trumpeter Swan) population High variability of migration strategies in a re-established Cygnus buccinator (Trumpeter Swan) population
The Interior Population (IP) of Cygnus buccinator (Trumpeter Swan), formerly extirpated by market hunting, was re-established in eastern North America by releasing individuals from both migratory and non-migratory populations. Their current annual movement patterns are largely unknown. We deployed 113 GPS-GSM transmitters on IP C. buccinator in 6 U.S. states and 1 Canadian province...

Effects of insecticide spray drift on arthropod prey resources of birds in grasslands in Minnesota Effects of insecticide spray drift on arthropod prey resources of birds in grasslands in Minnesota
Soybean aphid (Aphis glycines) insecticides are used throughout the Upper Midwest and Great Plains regions of North America, including the farmland region of Minnesota, USA, to combat insect pests. These broad-spectrum, foliar spray insecticides have the potential to drift beyond target fields into nearby grassland cover where birds and other insectivores forage. Arthropods serve...

Bird-habitat associations and local-scale vegetation structure in lowland brushlands Bird-habitat associations and local-scale vegetation structure in lowland brushlands
Brushlands support a diverse suite of bird species, including species of conservation concern in the western Great Lakes region of central North America. Information on how to effectively manage lowland brushlands for birds and associations between breeding birds and local-scale vegetation structure and composition is lacking. We surveyed lowland brushlands from 2016–2018 in Minnesota...

Declining American Goshawk (Accipiter atricapillus) nest site habitat suitability in a timber production landscape: Effects of abiotic, biotic, and forest management factors Declining American Goshawk (Accipiter atricapillus) nest site habitat suitability in a timber production landscape: Effects of abiotic, biotic, and forest management factors
Conservation of the American Goshawk (Accipiter atricapillus; hereafter goshawk) has been contentious in relation to forest management. Higher quality goshawk nesting habitat is generally considered to consist of contiguous tracts of mature forest, due to goshawks' large home ranges, territoriality, and food requirements. The large trees of mature forest have the greatest economic value...

Marshbird response to herbicide control of cattail in northwestern Minnesota Marshbird response to herbicide control of cattail in northwestern Minnesota
Wetlands provide essential habitat for a wide variety of wildlife species. In the once wetland-rich Prairie Pothole Region and adjacent areas of central North America, many wetlands have been converted to agricultural production. Many remaining wetlands experience ecological change via the invasion and spread of non-native plant species, such as non-native narrowleaf (Typha angustifolia)...

Exposure to risk factors experienced during migration is not associated with recent Vermivora warbler population trends Exposure to risk factors experienced during migration is not associated with recent Vermivora warbler population trends
Context Understanding the factors limiting populations of animals is critical for effective conservation. Determining which factors limit populations of migratory species can be especially challenging because of their reliance on multiple, often geographically distant regions during their annual cycles.Objectives We investigated whether distribution-wide variation in recent breeding...
