Age-Related Differences in Ruddy Turnstone Foraging and Aggressive Behavior
AGE-RELATED DIFFERENCES IN RUDDY TURNSTONE FORAGING AND AGGRESSIVE BEHAVIOR SARAH GROVES ABSTRACT.--Theforaging behavior of fall migrant Ruddy Turnstoneswas studiedon the Mas- sachusettscoast on 2 different substrates,barnacle-covered rocks and sand and weed-litteredflats. Foragingrates differedsignificantly between the 2 substrates.On eachsubstrate the foragingand successrates of adults and juveniles differed significantly while the frequenciesof successwere similarfor both age-classes.The observeddifferences in foragingrates of adultsand juvenilesmay be due to the degreeof refinementof foragingtechniques. Experience in searchingfor and handling prey may be a primary factor accountingfor thesedifferences, and foragingperformance probably improves with age and experience.Alternatively, the differencesmay be due to the presenceof inefficient juveniles that do not survive to adulthood. Both adultsand juveniles in the tall-depressedposture were dominant in aggressiveinteractions much morefrequently than birds in the tall-levelposture. In mixedflocks of foragingadult and juvenile turnstones,the four possibletypes of aggressiveinteractions occurred nonrandomly. Adult over juvenile interactionsoccurred more frequently than expected,and juvenile over adult interac- tions were never seen.A tentative explanationof this phenomenonmay be that juveniles misinter- pret or respondambivalently to messagesconveyed behaviorally by adultsand thusbecome espe- cially vulnerableto aggressionby adults.The transiencyof migrantsmade it unfeasibleto evaluate -

S A T R ER G S RO CHOOLS P Red Knot (Calidris canutus) Description The Red Knot is a chunky, medium sized shorebird that measures about 10 inches from bill to tail. When in its breeding plumage, the edges of its head and the underside of its neck and belly are orangish. The bird’s upper body is streaked a dark brown. It has a brownish gray tail and yellow green legs and feet. In the winter, the Red Knot carries a plain, grayish plumage that has very few distinctive features. Call Its call is a low, two-note whistle that sometimes includes a churring “knot” sound that is what inspired its name. -

Although free-flying ducks and geese have been extensively monitored for APMV, limited information is available for species in the order Charadriiforrnes. From 2000 to 2005 we tested cloacal swabs from 9,128 shorebirds and gulls (33 species, five families) captured in 10 states within the USA and in three countries in the Caribbean and South America. Avian paramyxoviruses were isolated from 60 (0.7%) samples by inoculation of embryonating chicken eggs; isolates only included APMV-1 and APMV-2. -
Bird Observations in Siriuspasset, North Greenland, 2016 and 2017
Bird observations in Siriuspasset, North Greenland, 2016 and 2017 WON YOUNG LEE (Med et dansk resumé: Fugleobservationer i Siriuspasset, Nordgrønland, 2016 og ’17) Abstract During the summer seasons of 2016 and 2017, bird observations were recorded near Siriuspasset in Nansen Land, North Greenland. Breeding birds were surveyed in a 9 km2 area. Wader populations were dense compared to other sites in North and Northeast Greenland, and Red Phalarope Phalaropus fulicarius and Lapland Longspur Calca- rius lapponicus were found to breed far north of their previously known distributions in Greenland.

Wader Population Censuses in the Arctic: Getting the Timing Right HANS MELTOFTE1
ARCTIC VOL. 54, NO. 4 (DECEMBER 2001) P. 367– 376 Wader Population Censuses in the Arctic: Getting the Timing Right HANS MELTOFTE1 (Received 12 May 2000; accepted in revised form 3 January 2001) ABSTRACT. There is increasing evidence that breeding wader censuses often have significantly underestimated densities in the Arctic and other areas. This evidence includes the recording of many more red knots Calidris canutus in the West Palearctic and African wintering areas than can be accounted for on the Arctic breeding grounds. The main causes of underestimated breeding numbers are that many species behave very inconspicuously during incubation, when most censuses have been performed, and that censuses taken later, during the chick-rearing period, record only successful breeding attempts. Records of four seasons at Zackenberg in central Northeast Greenland suggest that in the Arctic, the best population density data are obtained by mapping pairs and territorial individuals during the pair formation, territory establishment, and egg-laying periods, that is, when all birds are present and easiest to record. Revised summer population estimates for Old World wintering Nearctic waders are 20–200% higher than previous estimates. Key words: behaviour, breeding phenology, census methodologies, eastern Canadian Arctic, Northeast Greenland, population densities, population sizes, shorebirds, waders, Zackenberg RÉSUMÉ. On a de plus en plus de preuves que les recensements d’échassiers nicheurs ont souvent largement sous-estimé les densités dans l’Arctique et dans d’autres régions. Ces preuves comprennent le fait que l’on recense beaucoup plus de bécasseaux maubèches Calidris canatus dans les aires d’hivernage du paléarctique occidental et d’Afrique que l’on ne peut en compter sur les lieux de reproduction dans l’Arctique. -
Ruddy Turnstone Arenaria Interpres [M,W]
Appendix A: Birds Ruddy Turnstone Arenaria interpres [M,W] Federal Listing N/A State Listing N/A Global Rank G5 State Rank SNR Regional Status Very High Photo by Pamela Hunt Justification (Reason for Concern in NH) Populations of several migratory shorebirds are in steep decline (Andres 2009, Winn et al. 2013). Based largely on these declines, several species were proposed as RSGCN for the Northeast, and those that occur regularly in NH are included in the 2015 NH Wildlife Action Plan. Distribution Ruddy Turnstones breed across the arctic from Alaska to Siberia, and have an extensive wintering range along south temperate and tropical coastlines worldwide (Nettleship 2000). In New Hampshire the species is relatively uncommon, and limited to the immediate coast and Isles of Shoals. Most occur during migration in August and September, with lesser numbers in May. There are also a few winter records, but the species is quite rare between November and April. Habitat During the non‐breeding season, turnstones forage primarily on rocky shorelines, although they will occasionally use beaches and mudflats. NH Wildlife Action Plan Habitats ● Coastal Islands ● Estuarine ● Dunes Distribution Map New Hampshire Wildlife Action Plan Appendix A Birds-50 Appendix A: Birds Current Species and Habitat Condition in New Hampshire Populations of many long‐distance migrant shorebirds are believed to be in steep decline, and for this reason several species are considered priorities for future conservation. Although data for Ruddy Turnstone is somewhat equivocal, most recent assessments suggest its populations in North America are stable or increasing (Morrison et al. 1994, Morrison et al. -
