												  Bird Studies OverviewChapter 7. Bird Studies Overview teigerwald Lake National Wildlife Refuge provides a variety of habitats for many species of birds. Thousands of breeding birds rely on the resources of the refuge to Srest, eat, and raise their young. In addition, the refuge supports wetlands that are vital to the survival of migratory birds. The activities that follow offer an excellent opportunity for students to learn about and to observe the different species of birds — their behaviors and adaptations to the habitats on the refuge. Background The actively managed refuge wetlands and grasslands, when combined with the natural floodplain vegetative communities, provide habitat that supports over 200 species of birds. Hundreds of thousands of birds migrate along the lower Columbia River every year. The refuge hosts thousands of migratory birds that fly thousands of miles from their breeding grounds in Arctic Canada and Alaska to their wintering grounds in Baja California or South America, a route known as the Pacific Flyway. The few remaining areas of wetland habitat along the lower Columbia River are vital to the flyway. Some birds spend their winter on refuge wetlands, returning north to nest; some nest here but migrate to milder climates in the south for the winter; and some do not migrate at all but remain in the area as permanent residents. Several of the songbirds found in the summer spend our winters in Central and South America, migrating thousands of miles annually between their summer and winter habitats. Birds using the refuge are specifically adapted to the type of food they eat and the type of habitat they occupy (open water, freshwater wetland, field, riparian woodland, or upland woodland).

They are intelligent, wary and adapt well to or overpower. Crows also feed on the carcasses of winter – human activity. As with most other wildlife species, crows and road-killed animals. are considered to have “good” points and “bad” ones— value judgements made strictly by humans. They are found Crows have extremely keen senses of sight and hearing. in all 50 states and parts of Canada and Mexico. They are wary and usually post sentries while they feed.

												  Hungary & TransylvaniaAlthough we had many exciting birds, the ‘Bird of the trip’ was Wallcreeper in 2015. (János Oláh) HUNGARY & TRANSYLVANIA 14 – 23 MAY 2015 LEADER: JÁNOS OLÁH Central and Eastern Europe has a great variety of bird species including lots of special ones but at the same time also offers a fantastic variety of different habitats and scenery as well as the long and exciting history of the area. Birdquest has operated tours to Hungary since 1991, being one of the few pioneers to enter the eastern block. The tour itinerary has been changed a few times but nowadays the combination of Hungary and Transylvania seems to be a settled and well established one and offers an amazing list of European birds. This tour is a very good introduction to birders visiting Europe for the first time but also offers some difficult-to-see birds for those who birded the continent before. We had several tour highlights on this recent tour but certainly the displaying Great Bustards, a majestic pair of Eastern Imperial Eagle, the mighty Saker, the handsome Red-footed Falcon, a hunting Peregrine, the shy Capercaillie, the elusive Little Crake and Corncrake, the enigmatic Ural Owl, the declining White-backed Woodpecker, the skulking River and Barred Warblers, a rare Sombre Tit, which was a write-in, the fluty Red-breasted and Collared Flycatchers and the stunning Wallcreeper will be long remembered. We recorded a total of 214 species on this short tour, which is a respectable tally for Europe. Amongst these we had 18 species of raptors, 6 species of owls, 9 species of woodpeckers and 15 species of warblers seen! Our mammal highlight was undoubtedly the superb views of Carpathian Brown Bears of which we saw ten on a single afternoon! 1 BirdQuest Tour Report: Hungary & Transylvania 2015 www.birdquest-tours.com We also had a nice overview of the different habitats of a Carpathian transect from the Great Hungarian Plain through the deciduous woodlands of the Carpathian foothills to the higher conifer-covered mountains.

												  Species Almanac • Nature Activities AtThe deeriNature Almanac What is the i in deeriNature? Is it information, internet? How about identification. When you go out on the Deer Isle preserves, what species are you almost certain to encounter? Which ones might you wish to identify? Then how do you organize your experience so that learning about the nearly overwhelming richness of nature becomes wonderfully satisfying? A century ago every farmer, medicine woman, and indeed any educated man or woman felt that they should have a solid knowledge of the plants around them. The Fairbanks Museum in St. Johnsbury, Vermont has maintained a Flower Table with labeled specimens since 1905. The Deer Isle-Stonington Historical Society has an antique herbarium collection made by Ada Southworth, a Dunham’s point rusticator. Today there are lovely field guides galore but the equivalent of a local list can come to you now by digital download. Here is an almanac, a list of likely plant and animal species (and something about rocks too) for our Deer Isle preserves, arranged according to season and habitat. Enjoy this free e-Book on your desktop, tablet or smartphone. Take this e-book with you on the trails and consult the Point of Interest signs. If you have a smartphone and adequate coverage, at some preserves a QR code will tell you more at the Points of Interest. After each category on the lists you will find suggestions for books to consult or acquire. You will have to read the on line reviews for apps as that field is developing too rapidly for any other approach.

												  Predator and Competitor Management Plan for Monomoy National Wildlife RefugeAppendix J /USFWS Malcolm Grant 2011 Fencing exclosure to protect shorebirds from predators Predator and Competitor Management Plan for Monomoy National Wildlife Refuge Background and Introduction Background and Introduction Throughout North America, the presence of a single mammalian predator (e.g., coyote, skunk, and raccoon) or avian predator (e.g., great horned owl, black-crowned night-heron) at a nesting site can result in adult bird mortality, decrease or prevent reproductive success of nesting birds, or cause birds to abandon a nesting site entirely (Butchko and Small 1992, Kress and Hall 2004, Hall and Kress 2008, Nisbet and Welton 1984, USDA 2011). Depredation events and competition with other species for nesting space in one year can also limit the distribution and abundance of breeding birds in following years (USDA 2011, Nisbet 1975). Predator and competitor management on Monomoy refuge is essential to promoting and protecting rare and endangered beach nesting birds at this site, and has been incorporated into annual management plans for several decades. In 2000, the Service extended the Monomoy National Wildlife Refuge Nesting Season Operating Procedure, Monitoring Protocols, and Competitor/Predator Management Plan, 1998-2000, which was expiring, with the intent to revise and update the plan as part of the CCP process. This appendix fulfills that intent. As presented in chapter 3, all proposed alternatives include an active and adaptive predator and competitor management program, but our preferred alternative is most inclusive and will provide the greatest level of protection and benefit for all species of conservation concern. The option to discontinue the management program was considered but eliminated due to the affirmative responsibility the Service has to protect federally listed threatened and endangered species and migratory birds.
