Rocky Mountain Bird Observatory, 2005 Executive Summary Birds can be excellent indicators of environmental quality and change. In addition, they are one of the most highly visible valued components of our native wildlife. Monitoring birds provides data needed not only to effectively manage bird populations, but also to understand the effects of human activities on the ecosystem and to gauge their sustainability. Because bird communities reflect an integration of a broad array of ecosystem conditions, monitoring entire bird communities at the habitat level offers a cost-effective means for monitoring biological integrity at a variety of scales. In 2004, Rocky Mountain Bird Observatory (RMBO), in conjunction with its funding partner, the Black Hills National Forest (BHNF), implemented the fourth year of Monitoring the Birds of the Black Hills (MBBH), as delineated by Panjabi et al. (2001). RMBO has designed this program to provide statistically rigorous long-term trend data for populations of most diurnal, regularly breeding bird species in the Black Hills, including some U.S. Forest Service Region 2 Sensitive Species and BHNF Management Indicator Species (MIS). In the short term, this program provides information needed to effectively manage and conserve bird populations in the Black Hills, including the spatial distribution, abundance, and relationship to important habitat characteristics for each species. This cooperative project supports the BHNF’s efforts to comply with requirements set forth in the National Forest Management Act and other statutes and regulations. It also contributes to RMBO’s broader landscape-scale breeding bird monitoring program, which currently includes 11 states in the Rocky Mountains and Great Plains regions. As in 2003, RMBO surveyed 5 of the 10 habitats targeted under the monitoring plan, maintaining a level of effort consistent with funding. RMBO staff conducted 140 point transect surveys (2,036 point counts) in five habitats within the Black Hills (aspen, burn area, late-successional ponderosa pine, mixed-grass prairie, and pine-juniper shrubland). RMBO did not survey four habitats covered in 2002 (ponderosa pine-north, ponderosa pine-south, montane riparian, white spruce) or the foothill riparian habitat that was last surveyed in 2002. New survey sites were added and others were dropped in aspen, late-successional pine, mixed-grass prairie, and pine-juniper shrubland. RMBO staff recorded a total of 111 breeding bird species on point transects in the five habitats, many of which were observed on only a few occasions. The habitat-stratified point transect data provided good results (CV of ≤ 50% in at least one habitat) on 47 bird species, including two BHNF Management Indicator Species (MIS) and two Region 2 Sensitive Species, and fair results (CV of 51-100% in at least one habitat) on two additional species. The 47 species should be effectively monitored under the current program in at least one of the five habitats surveyed this year, although some of these may be better monitored in other habitats not surveyed this year. Four additional species, including one BHNF MIS and one BHNF (proposed)

Here in North America, birds that live on or near the ground. The sparrows are divided into 13 genera, which also cryptic blend of gray, white, black, and brown includes the towhees (genus Pipilo), longspurs hues which comprise a typical sparrow’s color (genus Calcarius), juncos (genus Junco), and pattern is the result of tens of thousands of Lark Bunting (genus Calamospiza) – all of sparrow generations living in grassland and which are technically sparrows. Emberizidae is brushland habitats. The triangular or cone- a large family, containing well over 300 species shaped bills inherent to most all sparrow species are perfectly adapted for a life of granivory – of crushing and husking seeds. “Of Louisiana’s 33 recorded sparrows, Sparrows possess well-developed claws on their toes, the evolutionary result of so much time spent on the ground, scratching for seeds only seven species breed here...” through leaf litter and other duff.

    U.S. Fish & Wildlife Service Plum Tree Island National Wildlife Refuge Draft Comprehensive Conservation Plan and Environmental Assessment January 2017 Front cover: Salt marsh Jeff Brewer/USACE This blue goose, designed by J.N. “Ding” Darling, has become the symbol of the National Wildlife Refuge System. The U.S. Fish and Wildlife Service (Service) is the principal Federal agency responsible for conserving, protecting, and enhancing fish, wildlife, plants, and their habitats for the continuing benefit of the American people. The Service manages the National Wildlife Refuge System comprised of over 150 million acres including over 560 national wildlife refuges and thousands of waterfowl production areas. The Service also operates 70 national fish hatcheries and over 80 ecological services field stations. The agency enforces Federal wildlife laws, manages migratory bird populations, restores nationally significant fisheries, conserves and restores wildlife habitat such as wetlands, administers the Endangered Species Act, and helps foreign governments with their conservation efforts. It also oversees the Federal Assistance Program which distributes hundreds of millions of dollars in excise taxes on fishing and hunting equipment to state wildlife agencies. Comprehensive Conservation Plans (CCPs) provide long-term guidance for management decisions on a refuge and set forth goals, objectives, and strategies needed to accomplish refuge purposes. CCPs also identify the Service’s best estimate of future needs. These plans detail program levels that are sometimes substantially above current budget allocations and, as such, are primarily for Service strategic planning and program prioritization purposes. CCPs do not constitute a commitment for staffing increases, operational and maintenance increases, or funding for future land acquisition.

    EFFECTS OF MANAGEMENT PRACTICES ON GRASSLAND BIRDS: VESPER SPARROW Grasslands Ecosystem Initiative Northern Prairie Wildlife Research Center U.S. Geological Survey Jamestown, North Dakota 58401 This report is one in a series of literature syntheses on North American grassland birds. The need for these reports was identified by the Prairie Pothole Joint Venture (PPJV), a part of the North American Waterfowl Management Plan. The PPJV recently adopted a new goal, to stabilize or increase populations of declining grassland- and wetland-associated wildlife species in the Prairie Pothole Region. To further that objective, it is essential to understand the habitat needs of birds other than waterfowl, and how management practices affect their habitats. The focus of these reports is on management of breeding habitat, particularly in the northern Great Plains. Suggested citation: Dechant, J. A., M. F. Dinkins, D. H. Johnson, L. D. Igl, C. M.

  • Structure of Lark Sparrow Song in California Edward R
    STRUCTURE OF LARK SPARROW SONG IN CALIFORNIA EDWARD R. PANDOLFINO, 1328 49th Street, Sacramento, California 95819; [email protected] RICHARD W. HEDLEY, Department of Biological Sciences, University of Alberta, 116 St. & 85 Ave., Edmonton, Alberta T6G 2R3, Canada ABSTRACT: We studied the song of the Lark Sparrow (Chondestes gramma- cus) in recordings of 15 individuals from a variety of locations in California. Lark Sparrow song is delivered as variable sequences structured in a hierarchy of four levels: elements, syllables, strophes, and themes. At the simplest level, elements can be distinguished by their appearance on a spectrogram. Birds vary the number of repetitions of each element to produce a syllable and string together several syllables to produce a strophe (mean 5.9 syllables per strophe). Strophes are delivered at an average rate of 5.4 per minute. Strophes can be further classified as belonging to one of a few themes in a male’s repertoire, where strophes in different themes are composed of almost entirely distinct elements and syllables. In <6% of strophes did we find elements from one theme mixed with elements from a different theme. Each individual sang one to three themes. The size of the repertoire of strophes is large but we could not quantify it because within a continuous bout of singing any particular sequence of syllables was repeated in only 5% of strophes. Each theme comprised roughly 20–40 distinct syllables. Thus an individual singing three themes could have a repertoire of 60–120 syllables. The number of unique elements per theme ranged from 11 in birds revealing just one theme up to 39 in birds revealing three themes, but longer recordings may have yielded more elements per bird.
