Predator and Competitor Management Plan for Monomoy National Wildlife Refuge
Appendix 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. -

99 PRIMARY MOULT, BODY MASS AND MOULT MIGRATION OF LITTLE TERN STERNAALBIFRONS IN NE ITALY GIUSEPPE CHERUBINI, LORENZO SERRA & NICOLA BACCETTI Cherubini G., L. Serra & N. Baccetti 1996. Primary moult, body mass and moult migration of Little Tern Sterna albifrons in NE Italy. Ardea 84: 99 114. Large post-breeding gatherings of Little Terns Sterna albifrons are regu larly observed in the Lagoon of Venice, Italy. Here, during five consecutive \ 1/ trapping seasons, 2956 birds were examined and ringed. Their breeding area, as indicated by 163 direct recoveries (mainly juveniles, ringed as chicks), spans over a broad sector of the Adriatic coasts, with colonies lo cated up to 133 km far. During their stay at the study area, adults undergo an almost complete moult. Two partial primary moult cycles can be ob \ served, the first of them being suspended when 2-4 outermost long primar ies have not yet been shed. Pre-migratory body mass build-up, enough for a ~/ flight longer than 1000 km, takes place during the very last days before de parture to the winter quarters, in most cases when the moult has reached a I suspended stage. Active primary moult and body mass increase do overlap in late moulting birds (after 27 August), indicating that the two processes are compatible, in case of time shortage. Post-breeding movements to the Lagoon of Venice seem to fit most requisites of moult migration.

Terns Nesting in Boston Harbor: the Importance of Artificial Sites
Terns Nesting in Boston Harbor: The Importance of Artificial Sites Jeremy J. Hatch Terns are familiar coastal birds in Massachusetts, nesting widely, but they are most numerous from Plymouth southwards. Their numbers have fluctuated over the years, and the history of the four principal species was compiled by Nisbet (1973 and in press). Two of these have nested in Boston Harbor: the Common Tern (Sterna hirundo) and the Least Tern (S. albifrons). In the late nineteenth century, the numbers of all terns declined profoundly throughout the Northeast because of intensive shooting of adults for the millinery trade (Doughty 1975), reaching their nadir in the 1890s (Nisbet 1973). Subsequently, numbers rebounded and reached a peak in the 1930s, declined again to the mid-1970s, then increased into the 1990s under vigilant protection (Blodget and Livingston 1996). In contrast, the first terns to nest in Boston Harbor in the twentieth century were not reported until 1968, and there are no records from the 1930s, when the numbers peaked statewide. For much of their subsequent existence the Common Terns have depended upon a sequence of artificial sites. This unusual history is the subject of this article. For successful breeding, terns require both an abimdant food supply and nesting sites safe from predators. Islands in estuaries can be ideal in both respects, and it is likely that terns were numerous in Boston Harbor in early times. There is no direct evidence for — or against — this surmise, but one of the former islands now lying beneath Logan Airport was called Bird Island (Fig. 1) and, like others similarly named, may well have been the site of a tern colony in colonial times. -

Common Birds of the Estero Bay Area
Common Birds of the Estero Bay Area Jeremy Beaulieu Lisa Andreano Michael Walgren Introduction The following is a guide to the common birds of the Estero Bay Area. Brief descriptions are provided as well as active months and status listings. Photos are primarily courtesy of Greg Smith. Species are arranged by family according to the Sibley Guide to Birds (2000). Gaviidae Red-throated Loon Gavia stellata Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: A small loon seldom seen far from salt water. In the non-breeding season they have a grey face and red throat. They have a long slender dark bill and white speckling on their dark back. Information: These birds are winter residents to the Central Coast. Wintering Red- throated Loons can gather in large numbers in Morro Bay if food is abundant. They are common on salt water of all depths but frequently forage in shallow bays and estuaries rather than far out at sea. Because their legs are located so far back, loons have difficulty walking on land and are rarely found far from water. Most loons must paddle furiously across the surface of the water before becoming airborne, but these small loons can practically spring directly into the air from land, a useful ability on its artic tundra breeding grounds. Pacific Loon Gavia pacifica Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: The Pacific Loon has a shorter neck than the Red-throated Loon. The bill is very straight and the head is very smoothly rounded. -

Common Tern Sterna Hirundo
Common Tern Sterna hirundo Dick Young CURRENT STATUS: In Pennsylvania, the common tern is endangered and protected under the Game and Wildlife Code. In the northeastern United States, the U.S. Fish and Wildlife Service lists the common tern as a migratory bird of conservation concern in the lower Great Lakes region. Nationally, they are not listed as an endangered/threatened species. All migratory birds are protected under the federal Migratory Bird Treaty Act of 1918. POPULATION TREND: Common terns (Sterna hirundo) have not nested successfully in Pennsyl- vania for many years; however the potential for nesting still exists. The only location with suitable nest- ing habitat is their historic nest site at Presque Isle State Park in Erie County. They once nested in abun- dance on Gull Point at the east end of the park, where more than 100 pairs were recorded in the early 1930s. Frequent disturbances by recreational beach-goers led to abandonment of the site. In 1985, the common tern was determined to be “extirpated,” or absent as a nesting species, in the Pennsylvania Bio- logical Survey’s Species of Special Concern in Pennsylvania. In 1999 the species was upgraded to “endangered” after a nesting pair was found in the newly protected Gull Point Natural Area at Presque Isle. The vulnerable eggs were destroyed before hatching, however. More recently, there were unsuc- cessful nesting attempts in 2012 and 2014. Despite these disappointments, common terns are fairly common to abundant migrants along Lake Erie, offering hope that breeding birds will stay to nest once again in Pennsylvania. -
