Coastal Wetlands Species Fact Sheet TEXAS PARKS AND WILDLIFE Whooping Crane Grus americana TPWD PHOTO Whooping cranes are one of the rarest bird species in North America. Although they breed in Canada during the summer months, whooping cranes migrate to Texas’ coastal plains near Rockport for the winter months. COASTAL WETLANDS Whooping Crane Grus americana APPEARANCE BEHAVIOR Height: 5 feet (1.5 m) Whooping cranes begin their fall migration south to Texas in Wingspan: 7.5 feet (2.3 m) mid-September and begin the spring migration north to Canada in late March or early April.

PEOPLE Life span: 10 to 15 years The name “raccoon” came from an Algonquian Indian word arakun, which means “he scratches with his hands.” During the 1700s, American colonists dropped the “a” in arakun, and the name became raccoon. Wild raccoons accustomed to being fed by well-intentioned people will generally loose their natural fear of humans and seek to move closer to their food source–your house. Once raccoons take up residence in an attic or outbuildings they can become very destructive and difficult to remove. Malnutrition, diseases like rabies, and predation by humans, coyotes and bobcats take their toll, but raccoon populations are not in decline in most areas of Texas.

  • Roseate Spoonbill Breeding in Camden County: a First State Nesting Record for Georgia
    vol. 76 • 3 – 4 THE ORIOLE 65 ROSEATE SPOONBILL BREEDING IN CAMDEN COUNTY: A FIRST STATE NESTING RECORD FOR GEORGIA Timothy Keyes One Conservation Way Brunswick, GA 31520 [email protected] Chris Depkin One Conservation Way Brunswick, GA 31520 [email protected] Jessica Aldridge 6222 Charlie Smith Sr. Hwy St. Marys, GA 31558 [email protected] Introduction We report the northernmost breeding record of Roseate Spoonbill (Platalea ajaja) on the Atlantic Coast of the U.S. Nesting activity has been suspected in Georgia for at least 5 years, but was first confirmed in June 2011 at a large wading bird colony in St. Marys, Camden County, Georgia. Prior to this record, the furthest northern breeding record for Roseate Spoonbill was in St. Augustine, St. John’s County, Florida, approximately 100 km to the south. This record for Georgia continues a trend of northward expansion of Roseate Spoonbill post-breeding dispersal and breeding ranges. Prior to the plume-hunting era of the mid to late 1800s, the eastern population of Roseate Spoonbill was more abundant and widespread than it is today (Dumas 2000), breeding across much of south Florida. Direct persecution and collateral disturbance by egret plume hunters led to a significant range contraction between 1850 and the 1890s (Allen 1942), limiting the eastern population of Roseate Spoonbills to a few sites in Florida Bay by the 1940s. A low of 15 nesting pairs were documented in 1936 (Powell et al. 1989). By the late 1960s, Roseate Spoonbills began to expand out of Florida Bay, slowly reclaiming some of the territory they had lost.

  • Business Plan for the Conservation of the American Oystercatcher
    Business Plan for the Conservation of the American Oystercatcher A 10-Year Plan to Secure a Coastal Keystone Species American Oystercatcher Working Group National Fish and Wildlife Foundation October 26, 2008 i WHAT IS A BUSINESS PLAN? A business plan serves two broad, primary functions. First, it provides specific information to those (e.g., prospective investors) not familiar with the proposed or existing business, including its goals and the management strategy and financial and other resources necessary to attain those goals. For outside individuals, it is imperative that the business plan offer a clear rationale for why the goals represent a good investment and why the strategy for achieving those goals is the best one possible. Second, a business plan provides internal guidance to those who are active in the operation of the business, allowing all individuals to understand where the business is headed and the means by which it will get there. The plan helps keep the business from drifting away from its goals and key actions through careful articulation of a strategy. In the context of the National Fish and Wildlife Foundation’s conservation efforts, business plans represent the strategies necessary to meet the goals of Keystone and other initiatives. At its core, each business plan emphasizes the type(s) and magnitude of the impacts (benefits) that will be realized through the initiative, the monetary costs involved, and the potential obstacles (risks) to achieving those gains. Readers of the business plan must be able to see the strength of the relationship between the activities identified within the strategy and the anticipated outcomes.

  • IDENTIFYING HYBRID OYSTERCATCHERS in SOUTHERN CALIFORNIA WALTER WEHTJE, 2286 Barbara Drive, Camarillo, California 93012; [email protected]
    FEATURED PHOTO IDENTIFYING HYBRID OYSTERCATCHERS IN SOUTHERN CALIFORNIA WALTER WEHTJE, 2286 Barbara Drive, Camarillo, California 93012; [email protected] The photo featured on the back cover of this issue was taken on 26 May 2005 on the south side of San Nicolas Island, Ventura County, California. Its subject appears to be a rather dark American Oystercatcher (Haematopus palliatus). A large shorebird of sandy beaches, tidal mudflats and rocky shores, along the Pacific coast this species ranges from central Chile to central Baja California. In central Baja California it is replaced by the Black Oystercatcher (H. bachmani), a bird of rocky shorelines that ranges north to the Aleutian Islands. For a 300-mile stretch along the Baja California peninsula the two species interbreed, forming a stable hybrid zone (Jehl 1985). Any pied oystercatcher observed north of the international border had probably wandered north from Baja California and has to be examined closely. Of the 35 documented sightings of “American” Oystercatchers in southern California, 11 have proved to be of hybrids (Cole and McCaskie 2004). So what constitutes a “good” American Oystercatcher? Jehl posed this question more than 20 years ago. Using techniques developed for studying hybrid popula- tions devised by Charles Sibley and his students (e.g., Sibley and Short 1959), Jehl established a hybrid index for black and pied oystercatchers. Specifically, he scored the uppertail coverts, tail, chest, undertail coverts, thighs, greater secondary coverts, extent of white wing stripe, underwing coverts, and axillaries from 0 (black, as in H. bachmani) to 4 (white, as in H. palliatus). The character score for the belly ranged from 0 to 6.

The Black Oystercatcher Haematopus bachmani , a monotypic species, is one of the less studied members of the genus. The global population of roughly 10,000 individuals is scattered unevenly along the North American Pacific Ocean coast from the Aleutian Islands to Baja California, with the vast majority (about 80%) in Alaska and British Columbia. Favouring rocky shorelines in areas of high tidal variation, they forage exclusively on intertidal macroinvertebrates (e.g. limpets and mussels). Because they are completely dependent on marine shorelines, the Black Oystercatcher is considered a sensitive indicator of the health of the rocky intertidal community. Breeding oystercatchers are highly territorial, and nesting densities are generally low; however, during the winter months they tend to aggregate in groups of tens to hundreds.

  • The Role of Coastal Engineering in American Oystercatcher Conservation April 2016
    THE ROLE OF COASTAL ENGINEERING IN AMERICAN OYSTERCATCHER CONSERVATION APRIL 2016 Chris Farrell Marianne Korosy Julie Wraithmell Audubon Florida Our mission is to conserve and restore natural ecosystems, focusing on birds, other wildlife, and their habitats for the benefit of humanity and the earth’s biological diversity. The production of this paper was supported by a grant from the National Fish and Wildlife Foundation. The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the opinions or policies of the U.S. Government or the National Fish and Wildlife Foundation. Mention of trade names or commercial products does not constitute their endorsement by the U.S. Government or the National Fish and Wildlife Foundation. The Role of Coastal Engineering in American Oystercatcher Conservation Executive Summary Humans have engineered the coasts for centuries, trying to create stability for the built environment in a system that is inherently dynamic. Continued coastal development and sea level rise are increasing the demand for engineered coastlines. Simultaneously, restoration dollars made available by the Deepwater Horizon settlements in the Gulf of Mexico will likely fuel a boom of such projects—from oyster reefs to armoring. These projects are often designed to achieve one particular goal such as coastal protection, oyster restoration, or erosion control, yet often have unintended impacts that jeopardize declining populations of coastal wildlife. With advanced planning and consideration, coastal engineering projects can be designed to minimize impacts and in some cases provide benefits to these species. This report summarizes the impacts of coastal engineering on the American Oystercatcher and provides recommendations for permit applicants, project engineers, and regulatory reviewers to improve future projects for the benefit of these imperiled shorebirds.
