South Florida Wading Bird Report 2008 SOUTH FLORIDA WADING BIRD REPORT Volume 14 Mark I. Cook and Mac Kobza, Editors November 2008 IN MEMORY The contributors and editors of the South Florida Wading Bird Report dedicate this year’s issue to the memory of Damion Marx, Phil Heidemann and Gareth Akerman, three young ecologists who tragically lost their lives on March 13, 2008 while conducting an aerial survey of wading birds around Lake Okeechobee. Damion, Phil and Gareth were research students and professionals in the lab of Dale Gawlik at Florida Atlantic University, Boca Raton. Damion was close to finishing his PhD dissertation on the influence of patch structure on wading bird foraging patterns, Phil was an M.S. candidate developing a landscape suitability index for Wood Stork and White Ibis in Damion Marx southwestern Florida, and Gareth was looking to gain additional experience in conservation biology after recently completing his Masters dissertation on the role of riparian buffers in forest bird conservation at Dalhousie University, Canada. There is no question that all had a sense of adventure, a desire to improve our world and fervor for understanding and protecting nature. All were devoted to advancing wading bird conservation and Everglades restoration. They risked and lost their lives in the backwaters of south Florida, doing what they loved and what they passionately believed would benefit the ecosystems of south Florida. They will be sorely missed by their colleagues, but neither they nor their important research will be forgotten. Further words from their mentor and good friend, Dale Gawlik, can be found at the link below.

  • 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.

  • Great Egret Ardea Alba
    Great Egret Ardea alba Joe Kosack/PGC Photo CURRENT STATUS: In Pennsylvania, the great egret is listed state endangered and protected under the Game and Wildlife Code. Nationally, they are not listed as an endangered/threatened species. All migra- tory birds are protected under the federal Migratory Bird Treaty Act of 1918. POPULATION TREND: The Pennsylvania Game Commission counts active great egret (Ardea alba) nests in every known colony in the state every year to track changes in population size. Since 2009, only two nesting locations have been active in Pennsylvania: Kiwanis Lake, York County (fewer than 10 pairs) and the Susquehanna River’s Wade Island, Dauphin County (fewer than 200 pairs). Both sites are Penn- sylvania Audubon Important Bird Areas. Great egrets abandoned other colonies along the lower Susque- hanna River in Lancaster County in 1988 and along the Delaware River in Philadelphia County in 1991. Wade Island has been surveyed annually since 1985. The egret population there has slowly increased since 1985, with a high count of 197 nests in 2009. The 10-year average count from 2005 to 2014 was 159 nests. First listed as a state threatened species in 1990, the great egret was downgraded to endan- gered in 1999. IDENTIFYING CHARACTERISTICS: Great egrets are almost the size of a great blue heron (Ardea herodias), but white rather than gray-blue. From bill to tail tip, adults are about 40 inches long. The wingspan is 55 inches. The plumage is white, bill yellowish, and legs and feet black. Commonly confused species include cattle egret (Bubulus ibis), snowy egret (Egretta thula), and juvenile little blue herons (Egretta caerulea); however these species are smaller and do not nest regularly in the state.

  • Indiana Division of Fish & Wildlife's Animal Information Series: Paddlefish
    Indiana Division of Fish & Wildlife’s Animal Information Series Paddlefish (Polyodon spathula) Do they have any other names? Paddlefish are also called spoonbill, spoonbill cat, shovelnose cat, and boneless cat. Why are they called paddlefish? They are called paddlefish because of their paddle-like nose. Polyodon is Greek for “many tooth” in reference to the numerous long gill rakers and spathula is Latin for “spatula” or “blade.” What do they look like? Paddlefish are shark-like fish with long, paddle-shaped snouts. They have large mouths, without teeth, that are located far back on the underside of the head. Paddlefish have many gill rakers (filaments used to filter food from the water) that are long and slender. The eyes are small and just above the front edge of the mouth. The rear margin of the gill cover is long and pointed into a fleshy flap. The tail is deeply lobed with the upper lobe longer than the lower lobe. The skin is without scales and the skeleton is made of cartilage. Paddlefish are bluish-gray to black on the upper parts and light gray to white on the belly. Photo Credit: Duane Raver, USFWS Where do they live in Indiana? Paddlefish are rare to occasional in Indiana and they live in large rivers. What kind of habitat do they need? A paddlefish needs very specific habitat conditions to meet its needs. During most of its life it lives in quiet or slow-flowing waters rich in the microscopic life (zooplankton) on which it feeds. However, it must have access to a large, free-flowing river with gravel bars that flood frequently during its spawning season.

  • Guidance for Time of Year Restrictions on Colonial Water Birds and Wading Birds
    Guidance for time of year restrictions on colonial water birds and wading birds Abatement Plan Because time of year restrictions likely cannot be avoided and the project area is within areas known to be occupied by nesting shorebirds, we recommend that a bird abatement plan be developed in coordination with the Service and the LDWF. The abatement plan should include a monitoring plan including pre-construction and construction monitoring, anticipated abatement procedures, a report outline of daily monitoring and abatement activities, and include a post- construction report. Brown pelican (For use when only pelicans are present; for all nesting shorebird species, see “Colonial Nesting Waterbirds” further below in this document) The proposed project may affect nesting habitat for the brown pelican (Pelecanus occidentalis), which was officially removed from the List of Endangered and Threatened Species on December 17, 2009. Brown pelicans nest in Louisiana from April 1 through September 15. Nesting periods vary considerably among Louisiana’s brown pelican colonies, so it is possible that this breeding window could be altered based upon the dynamics of the individual colony. The Louisiana Department of Wildlife and Fisheries’ Coastal and Nongame Resources Division (225/765-2811) should be contacted to obtain the most current information about the nesting chronology of individual brown pelican colonies. Brown pelicans are known to nest on barrier islands and other coastal islands in St. Bernard, Plaquemines, Jefferson, Lafourche, and Terrebonne Parishes. Current nesting locations include Raccoon Point on Isles Dernieres, Queen Bess Island, Plover Island (Baptiste Collette), Wine Island, Rabbit Island in Calcasieu Lake (Cameron Parish), and islands in the Chandeleur chain.

  • Developing a Research Network on Glossy Ibis, a Neglected Cosmopolitan Species
    Developing a research network on Glossy ibis, a neglected cosmopolitan species Álvaro Arenas Patiño © 2014 The Project in a nutshell The Glossy ibis (Plegadis falcinellus) is the only cosmopolitan species of the Threskiornithidae family (ibis and spoonbills) and among the most widely distributed bird species in the world ([1] see map at the bottom of the document). Nonetheless, no knowledge exists on the intraspecific phylogeny and very little is known about the (meta)populations dynamics. We aim to fill this gap by setting up a research network and by implementing modern analytical tools (e.g. molecular and statistical) we nowadays dispose of. Some puzzling aspects of Glossy ibis abundance and distribution Little is known about the movement ecology of this species especially when focusing on a large spatial scale. In most ornithology books the Glossy ibis is described as migratory with nomadic elements [2] with populations at tropics being more sedentary than others. However, references are rarely provided and, to the best of our knowledge, only a few data have been ever collected on the Glossy ibis dispersal behavior. According to historical records, breeding was very rare in W Europe while common in North Africa and S Spain before the 20th century when it became almost absent in all these regions [3–5]. In 1996 seven pairs settled at Doñana, a wetland area in SW Spain, from where the species begun an astonishing population increase reaching about 8,000 pairs in current times [6,7]. Since then, the Glossy ibis has started to colonize other areas in W Europe and the Mediterranean Basin from where it had been absent for decades or even had never been recorded as a breeder species.
