High Counts: About 10 Greater White- fronted Geese were in Nels Three-Quarters Pasture in April 2011 (Ryan Cumbow pers. comm.). Remarks: In Central SD, Greater White- fronted Geese (Figure 15) are most often found mixed with large flocks of Canada or Snow Geese.

One or two Greater White-fronted Geese were heard with Canada Geese flying over Prairie Hills North Pasture on 10 February 2015 (DNS, Ryan Cumbow). SNOW GOOSE (Chen caerulescens) Status: Abundant but irregular spring and fall migrant, casual summer and winter visitor. Distribution: Snow Geese use cropland and large wetlands. Remarks: Snow Goose migration peaks in April and again from late September to early November. A lingering spring bird was near Dry Hole Chester Pasture on 1 May 2014 (DNS, Ryan Cumbow). A “blue” Snow Goose was observed several times in the SW portion of the checklist area (for example at Booth Dam) in June 2010 or 2011 (Ryan Cumbow pers. comm.).

  • Tyrannus Tyrannus) and Western (Tyrannus
    1 A COMPARISON OF INTER- AND INTRASPECIFIC AGGRESSION IN SYMPATRIC POPULATIONS OF EASTERN (TYRANNUS TYRANNUS) AND WESTERN (TYRANNUS VERTICALIS) KINGBIRDS By EDWIN HARRIS1 1Beloit College, Department of Biology, Beloit, WI 53511 Running head: HARRIS: KINGBIRD AGGRESSION 2 Abstract Tyrant flycatchers (Family Tyrannidae) are known for their aggression and intense nest defense. Predation pressure, risk of paternity loss to extrapair fertilizations, and interspecific competition have all been proposed as explanations for these traits. In this study, intensity of intra- and interspecific aggression were compared between Eastern (Tyrannus tyrannus) and Western (Tyrannus verticalis) kingbirds at a site in Western Montana. Due to differing nest site preferences between the species, interspecific aggression was expected to be limited, as microhabitat divergence may alleviate competitive pressure. Conspecific, heterospecific kingbird, and Western meadowlark (Sturnella neglecta) calls were presented, and Eastern and Western kingbird responses were recorded. Eastern kingbirds exhibited the highest frequency of aggressive behaviors in response to conspecific calls, followed by Western kingbird calls. Western kingbirds responded with higher frequency of aggressive behaviors to kingbirds regardless of species. Given the greater abundance of Eastern kingbirds at this site, these results may indicate that competition from Eastern kingbirds is a greater perceived threat to both species than competition from Western kingbirds. Key Words: Eastern kingbird;

  • Riparian Research and Management: Past, Present, Future
    Chapter 11. Terrestrial Vertebrates of Mesquite Bosques in Southwestern North America R. Roy Johnson, Elaine E. Johnson, and Steven W. Carothers Introduction The major emphasis of this chapter is to address the species richness and popula- tion densities of land vertebrates in riparian mesquite bosques (woodlands). We find no single publication that lists vertebrates—amphibians, reptiles, birds, and mammals—of riparian mesquites of the Southwest lowlands. These vertebrates are listed for a few river valleys, such as the Santa Cruz River (Webb et al. 2014) and San Pedro River (Stromberg and Tellman 2009), but not for the Southwest as a whole. This chapter pres- ents a summary of the vertebrate fauna of mesquite bosques. Our lists of vertebrates of bosques and/or associated cottonwood-willow forests and riparian deciduous woodlands have been constructed from literature, historic records and specimens, and our first-hand knowledge. Mesquite Bottomlands as Wildlife Habitat A large number of the vertebrate species occurring as obligate and facultative riparian species in cottonwood-willow gallery forests also occur in mesquite bosques. These species inhabit riparian mesquites not only along streams but also along dry watercourses (tables 12–15). An amphibian or reptile species may often occur in cotton- wood-willow or mixed deciduous forests, in mesquite bosques, or in upland ecosystems. A mammal species—except larger mammals and bats—may also often occur in one of these three watershed zones. Although an avian species may use one of those three zones, several species occur in all three zones. Some birds, especially larger species, roost and nest at distances from riparian ecosystems but spend parts of the day flying over and/or foraging in bosques and adjacent zones.

  • Bird Species Protected by the Migratory Bird Treaty
    BIRDS PROTECTED BY THE MIGRATORY BIRD TREATY ACT Species Protected by Each Migratory Bird Convention The United States has entered into four international migratory bird conventions (with Canada, Mexico, Japan, and Russia). Each of these conventions provides protection to a select group of species. The Canadian convention identifies protected groups by Family or species group names (for example, Anatidae, Rallidae, loons, warblers, and so forth). The Mexican convention identifies protected groups by Family names. The Japanese and Russian conventions identify protected species in Appendices to the conventions. The following list identifies those species protected by each of the conventions. Column headings: C = Canadian M = Mexican J = Japanese R = Russian Symbols: O = Family (or Subfamily) listed in convention (Canada and Mexico only) s = occurs regularly in both countries (Canada and Mexico only); + = occurs regularly in the U.S. but not Canada or Mexico (Canada and Mexico only); ? = status in U.S. is uncertain, and eligibility for continued protection is under review (Mexico only) X = listed in Appendix to convention (Japan and Russia only); o = belongs to same Family as species listed in Appendix to convention and occurs regularly in the U.S. (Russia only) English Name C M J R GAVIIDAE (Loons) O O Red-throated Loon s s X X Arctic Loon s + X X Pacific (=Arctic) Loon s X Common Loon s s o Yellow-billed Loon s s X X PODICIPEDIDAE (Grebes) O O Least Grebe + s o Pied-billed Grebe s s o Horned Grebe s s X X Red-necked Grebe s + X X Eared
