  • Patterns of Co-Occurrence in Woodpeckers and Nocturnal Cavity-Nesting Owls Within an Idaho Forest
    VOLUME 13, ISSUE 1, ARTICLE 18 Scholer, M. N., M. Leu, and J. R. Belthoff. 2018. Patterns of co-occurrence in woodpeckers and nocturnal cavity-nesting owls within an Idaho forest. Avian Conservation and Ecology 13(1):18. https://doi.org/10.5751/ACE-01209-130118 Copyright © 2018 by the author(s). Published here under license by the Resilience Alliance. Research Paper Patterns of co-occurrence in woodpeckers and nocturnal cavity- nesting owls within an Idaho forest Micah N. Scholer 1, Matthias Leu 2 and James R. Belthoff 1 1Department of Biological Sciences and Raptor Research Center, Boise State University, Boise, Idaho, USA, 2Biology Department, College of William and Mary, Williamsburg, Virginia, USA ABSTRACT. Few studies have examined the patterns of co-occurrence between diurnal birds such as woodpeckers and nocturnal birds such as owls, which they may facilitate. Flammulated Owls (Psiloscops flammeolus) and Northern Saw-whet Owls (Aegolius acadicus) are nocturnal, secondary cavity-nesting birds that inhabit forests. For nesting and roosting, both species require natural cavities or, more commonly, those that woodpeckers create. Using day and nighttime broadcast surveys (n = 150 locations) in the Rocky Mountain biogeographic region of Idaho, USA, we surveyed for owls and woodpeckers to assess patterns of co-occurrence and evaluated the hypothesis that forest owls and woodpeckers co-occurred more frequently than expected by chance because of the facilitative nature of their biological interaction. We also examined co-occurrence patterns between owl species to understand their possible competitive interactions. Finally, to assess whether co-occurrence patterns arose because of species interactions or selection of similar habitat types, we used canonical correspondence analysis (CCA) to examine habitat associations within this cavity-nesting bird community.

  • Coyote Reservoir & Harvey Bear..…
    Coyote Reservoir & Harvey Bear..…. February 24, south Santa Clara County Quick Overview – Watching the weather reports we all saw the storm coming, but a group of adventurous souls arrived with all their rain gear and ready to go regardless of the elements, and what a day we had! Once east of Gilroy and traveling through the country roads we realized that soaking wet birds create unique ID challenges. With characteristic feathers in disarray and the wet plumages now appearing much darker we had to leave some questionable birds off our list. We had wanted to walk some of the trails that make up the new Harvey Bear Ranch Park, but the rain had us doing most of our birding from the cars which was easy along Coyote Reservoir Road as it parallels the lake. It also makes it easy when no one else is in the park. We could stop anywhere we wanted and we were not in anyone’s way – a birder’s dream come true! Watching Violet Green Swallows by the hundreds reminded us all that spring is near. And at one stop we got four woodpecker species. Ending our day watching Bald Eagles grasp fish at the surface of the water was worth our getting all wet! And I’ll not soon forget our close encounter with the dam’s Rufous Crowned Sparrow. Since we started our day at the south entrance of the park we ended Rufous Crowned Sparrow our day at the north entrance. It was here we listened to above and hard working Western Meadowlarks and watched a Say’s Phoebe.

  • Bears in Oklahoma
    April 2010 Bears in Oklahoma Our speaker for the April 19 meeting of the Oklahoma City Audubon Society will be Jeremy Dixon, wildlife biologist at the Wichita Mountains Wildlife Refuge. His presentation is titled “The Strange But True History of Bears in Oklahoma.” For many years Jeremy was a biologist in Florida where he studied the interactions between black bears and humans. His master’s research was on the Conservation Genetics of the Florida Black Bear. Jeremy moved to Lawton in 2009 to experience life out here in the middle of the continent. Our grass prairie and ancient granite mountains are a new living environment for him. However, the black bears are coming back across Oklahoma from the east presenting birders an experience with a new and large predator to which we are unaccustomed. With an education from Jeremy, hopefully we can learn how to watch the birds while not feeding the bears ourselves. Come out for bear-hugging good time at bird club and bring a friend. County Birding: Kingfisher Jimmy Woodard On March 11, the group of 7 birders entered Kingfisher County in the far southeast corner. We located several small lakes with waterfowl: Canada Geese, Gadwall, Mallard, Green- Winged Teal and Ruddy Duck. We also found an adult Bald Eagle, the first of two found during the trip. Driving the back roads, we observed Great Horned Owl, Phoebe, King- fisher, and a bunch of sparrows – Harris, White Crowned, Song, Savannah, & Lincoln’s. We visited fields along the Cimarron River southeast of Dover. Carla Brueggen & her hus- band lease fields in this area.

  • Migration Chronology of Waterfowl in the Southern High Plains of Texas
    Migration Chronology of Waterfowl in the Southern High Plains of Texas LAURA BAAR1,2, RAYMOND S. MATLACK1,3, WILLIAM P. JOHNSON4 AND RAYMOND B. BARRON1 1Department of Life, Earth and Environmental Sciences, West Texas A&M University, Box 60808, Canyon, TX 79016-0001 2Current address: Texas Parks and Wildlife Department, P.O.Box 226, Karnack, TX 75661 3Corresponding author; Internet: [email protected] 4Texas Parks and Wildlife Department, P.O. Box 659, Canyon, TX 79015 Abstract.—Migration chronology was quantified for 15 waterfowl species on 58 playa wetlands in the Southern High Plains of Texas from February 2004 through April 2006. Abundance of each species was estimated on playas once every two weeks during the nonbreeding season (16 August to 30 April); presence of ice was also recorded. Dabbling ducks were most common (N = 250,668) and most tended to exhibit either a bimodal migration pattern (lower abundance in winter than during fall and spring passage) or a unimodal pattern (one defined peak). Abun- dance of the most common dabbling ducks was skewed toward late winter and spring. Most species of diving ducks (N = 15,128) tended to exhibit irregular migration patterns. Canada Geese (both Branta canadensis and B. hutchinsii, N = 15,347) had an abundance pattern that gradually increased, peaking in midwinter, and then decreased, which is typical for a terminal wintering area. Ice was most common on playas during the first half of December, which coincided with the lowest winter abundance in dabbling ducks. Data from this study will support management ef- forts focused on playa wetlands, including the development of population goals and habitat objectives that span the entire non-breeding season.

  • Nocturnal Survey Guidelines Owls, Nighthawks and Whip-Poor-Wills Present Atlas Surveyors with Several Challenges
    Nocturnal Survey Guidelines Owls, nighthawks and Whip-poor-wills present atlas surveyors with several challenges. Although many Minnesota species, including thrushes and marsh birds, may vocalize at sunset, pre-dawn, or even at night, most can be detected during early morning and daytime surveys. The surveyor’s chances of detecting most owls, however, as well as the common nighthawk and whip-poor-will, will be considerably enhanced by adding nocturnal surveys. Owls Minnesota’s 11 owl species are a mix of permanent, non-migratory residents (Eastern Screech Owl, Great Horned Owl and Barred Owl); summer residents (Long-eared Owl, Short-eared Owl, and Saw-whet Owl) and three species whose summer populations probably include both permanent residents and migratory invaders (Boreal Owl, Northern Hawk Owl and Great Gray Owl). The Burrowing Owl is an extremely rare summer resident in the western grassland region and the Barn Owl has been an erratic species whose status as a permanent resident or migratory invader is unknown. Three of these species tend to be more diurnal and the chances of seeing them during the day are relatively good. They include two open habitat species, the Short-eared Owl and Burrowing Owl, and one forest species, the Northern Hawk Owl. Like marsh hawks, Short- eared Owls can often be seen flying low over wet grasslands and marshes hunting for prey during the morning and early evening hours. The Burrowing Owl, a very rare nesting species in the state, is prominent as it stands as a sentinel atop its nesting burrow, just inches above the surrounding grassland.

  • Utilization of Hydrilla Verticillata by Wintering Waterfowl on the Tidal Potomac River
    UTILIZATION OF HYDRILLA VERTICILLATA BY WINTERING WATERFOWL ON THE TIDAL POTOMAC RIVER by Jeffrey A. Browning Advisor: Dr. Albert Manville Presented to the Faculty of the Graduate School of Johns Hopkins University In Partial Fulfillment of the Requirements For the Degree of Master of Science Johns Hopkins University May 2008 ABSTRACT Submersed aquatic vegetation (SAV) communities in the tidal Potomac River were decimated during the 20th century by multiple environmental and anthropogenic factors. With the major declines of SAV communities, waterfowl populations have declined greatly as well (Hindman 1989). Hydrilla verticillata, an introduced submersed aquatic plant, was first discovered in the tidal Potomac River in 1982 (Steward et al. 1984). One hundred nine waterfowl were collected from the tidal Potomac River and its tributaries during the 2007-2008 Virginian and Maryland waterfowl hunting seasons. The esophagi and gizzards were dissected and analyzed to determine the utilization of H. verticillata by wintering waterfowl. Only 2 duck species, Mallard (Anas platyrhynchos) and Lesser Scaup (Aythya affinis), consumed small amounts of H. verticillata, 2.52% and 0.20% aggregate percentage of esophageal content, respectively. An inverse relationship between H. verticillata and gastropod consumption was observed as the season progressed. i ACKNOWLEDGMENTS I would like to thank Dr. Albert Manville for his guidance and input during this research. Dr. Manville helped me reach decisions and get past certain obstacles. I would also like to thank Dr. Matthew Perry and Mr. Peter Osenton at the USGS Patuxent Wildlife Research Center for advice and consultation during the design of this study and analysis of the data.
