Migration Phenology of Jack Snipe Lymnocryptes Minimus at an Irish Coastal Wetland
Migration phenology of Jack Snipe Lymnocryptes minimus at an Irish coastal wetland Tom Cooney 42 All Saint’s Road, Raheny, Dublin D05 C627 Corresponding author: [email protected] Keywords: Ireland, Jack Snipe, Lymnocryptes minimus , migration phenology Migration times of Jack Snipe Lymnocryptes minimus were monitored at North Bull Island in Dublin Bay during 2011/2012 to 2016/2017. Average arrival times in autumn centred on 2 October and average departure times in spring on 23 April. Although these results were site and habitat specific, they were similar to recent migration data for Ireland. While the time series examined for Ireland and Britain were of different lengths, migration times were extraordinarily similar. The average autumn arrival date for Ireland as a whole was 16 September while that for Britain was 23 September, and departure times in spring for Ireland centred on 30 April, one day later than in Britain. The close agreement suggests that migration times across both islands possibly occur synchronously. Other recently generated data for Ireland provides tantalising evidence that passage migration may take place and that Jack Snipe could be more frequent in upland areas than previously suspected. In both instances greater clarity will only be possible through increased observer effort and higher detection rates of this enigmatic species. Introduction Britain, but not in Ireland (Smiddy 2002).

The First Record of Spotted Redshank Tringa Erythropus for South America
COTINGA 9 The first record of Spotted Redshank Tringa erythropus for South America David Fisher Se describe el registro del primer Tringa erythropus para América del Sur, en las lagunas Bon Accord, Tobago, el 13 febrero 1983. El registro ha sido recientemente aceptado por el Comité de Rarezas de Trinidad & Tobago. Se discute este registro a la luz de otras apariciones en USA, Barbados y aquellos de otras aves del Paleártico Occidental en Trinidad & Tobago. On the morning of 13 February 1983, while lead ing a combined Sunbird/Wings birdwatching tour to Trinidad and Tobago, I found a Spotted Redshank Tringa erythropus at the Bon Accord lagoons in south-west Tobago. It was associating with a small group of Willets Catoptrophorus semipalmatus, Greater Yellowlegs Tringa melanoleuca and Lesser Yellowlegs T. flavipes. Features which immediately made the bird stand out from the other waders present were its Figure 1.

The Birds of Wimbledon Common and Putney Heath 2015
The Birds of Wimbledon Common and Putney Heath 2015 Male Wheatear on the log pile 1 The Birds of Wimbledon Common and Putney Heath 2015 The Birds of Wimbledon Common and Putney Heath 2015 espite coverage on the Common being rather poor again this year, a total of 96 species were D recorded, four more than in 2014. Of these, 45 bred or probably bred, with no doubt the highlight of the year being the successful breeding of a pair of Skylarks on the Plain, the first to do so since 2007. Much credit for this achievement must go to Wildlife & Conservation Officer, Peter Haldane, and his staff, who have persevered over the years to create a suitable and safe habitat for this Red-listed bird. Credit is also due to Chief Executive, Simon Lee, for his valuable cooperation, and indeed to the vast majority of the visiting public, many of whom have displayed a keen interest in the well-being of these iconic birds. Signage on the Plain this year was extended to the two uncut sections during the autumn and winter months, thus affording our migrants and winter-visiting birds a sanctuary in which to feed and shelter safely. Another outstanding high note this year was the Snow Bunting found on the Large Mound in January, a first for the Common since records began in 1974; and yet another first for the Common came in the form of three Whooper Swans at Rushmere in December. There was also a surprising influx of Lesser Spotted Woodpeckers during the spring, a bird that in the previous few years had become an extremely scarce visitor. -
Seriously Sage-Grouse
United States Department of Agriculture Natural Seriously Resources Conservation Service Farm Service Sage-Grouse Agency April 2011 Helping People Help the Land Seriously Sage-Grouse How Science Heard About Sage-Grouse Meriwether Lewis first observed sage-grouse at the mouth of the Marias River on June 6, 1805. The bird was new to science then and plentiful throughout the western part of what is now the United States. Journals from the Lewis and Clark expedition record sage-grouse encounters from the mouth of the Marias River, up the Missouri River to Camp Fortunate, along the trail to Lemhi Pass, along the Salmon River, down the Clearwater River, then to the confluence of the Walla Walla River with the Columbia. Since its first recorded sighting more than 200 years ago, the sage-grouse has experienced a large decline in population. Find the way through this maze and you will see the route Lewis and Clark took from the mouth of the Marias River in Montana to the Pacific Coast in Oregon. Hint: sage-grouse are pictured on the map at the places where the explorers recorded sightings. MONTANA Mar ias R . WASHINGTON M i s s o u ri R e . Cl arw a R. te ia W r olumb R.

Cranial Pneumatization Patterns and Bursa of Fabricius in North American Shorebirds
CRANIAL PNEUMATIZATION PATTERNS AND BURSA OF FABRICIUS IN NORTH AMERICAN SHOREBIRDS RAYIUOND MCNEIL AND JEAN BURTON study of age criteria in some species of North American shorebirds A brought us to consider two of the best known techniques of age deter- mination in birds, the size of the bursa of Fabricius and the degrees and pat- terns of skull pneumatization. The only attempt, known to us, to correlate bursa of Fabricius and gonadal development with the ossification of the skull is that of Davis (1947). The bursa of Fabricius is a lympho-epithelial organ lying dorsally above the cloaca. At least in some species it has an opening in the cloaca. It reaches its maximum size at 4-6 months and then begins involution (Davis, 1947). By cloaca1 examination of the bursal pouch, it is possible to distinguish juvenile from adult individuals of some taxa of birds especially Anseriformes and Galliformes (Gower, 1939; Hochbaum, 1942; Linduska, 1943; Kirkpatrick, 1944). Unfortunately, in shorebird species, the bursa of Fabricius has no cloaca1 opening and thus cannot be used as an age criterion of living birds. The pneumatization of the skull has been used as a criterion for estimating the age of birds by C. L. Brehm as far back as 1822 (Niethammer, 1968)) but it was not generally used until the turn of the century (Serventy et al., 1967). Miller (1946) describes the skull ossification process as follows: “The skull of a passerine bird when it leaves the nest is made of a single layer of bone in the area overlaying the brain; at least, the covering appears single when viewed mac- roscopically. -
Common Ravens, Corvus Corax, Preferentially Associate with Grey Wolves, Canis Lupus, As a Foraging Strategy in Winter
ANIMAL BEHAVIOUR, 2002, 64, 283–290 doi:10.1006/anbe.2002.3047, available online at http://www.idealibrary.com on Common ravens, Corvus corax, preferentially associate with grey wolves, Canis lupus, as a foraging strategy in winter DANIEL STAHLER*†, BERND HEINRICH* & DOUGLAS SMITH† *Department of Biology, University of Vermont †Yellowstone Center for Resources, Yellowstone National Park (Received 28 February 2001; initial acceptance 16 May 2001; final acceptance 22 January 2002; MS. number: A9007R) One foraging strategy that scavengers can employ to discover unpredictable food sources is to associate directly with predators who inadvertently provide food. The common raven, a well known feeding generalist, is also a prominent scavenger of wolves’ kills and is found to be in close association with this predator. We tested the hypothesis that ravens preferentially associate with wolves in winter as a kleptoparasitic foraging strategy. The presence, absence and behaviour of ravens was documented during winter observations of wolves, coyotes, Canis latrans, and elk, Cervus elaphus, as well as the landscape in the absence of these three species. Ravens were found to be in close association with wolves when they were travelling, resting and hunting prey. In comparison, ravens showed no significant association with coyotes, elk or areas on the landscape in the absence of wolves. We also compared ravens’ discovery success of wolf-killed and nonwolf-killed carcasses and their behavioural response upon discovery. Ravens found all wolf kills almost immediately and remained at the carcass to feed alongside wolves after the death of the prey. In contrast, ravens were less successful discovering experimentally placed carcasses in the same study region, and did not land or feed despite the availability of fresh, exposed meat. -

E-mail: [email protected] We analysed 324 recoveries from 2,817 Russian Woodcocks ringed as adult or yearling in two areas in Russia (Moscow and St Petersburg). We suspected that birds belonging to these two areas may experience different hunting pressure or climatic conditions, and thus exhibit different demographic parameters. To test this hypothesis, we analysed spatial and temporal distribution of recoveries, and performed a ringing-recovery analysis to estimate possible survival differences between these two areas. We used methods developed by Brownie et al. in 1985. We found differences in temporal variations of the age ratio between the two ringing areas. -

VOL. LU JULY No. 7 1959 BRITISH BIRDS WADER MIGRATION IN NORTH AMERICA AND ITS RELATION TO TRANSATLANTIC CROSSINGS By I. C. T. NISBET IT IS NOW generally accepted that the American waders which occur each autumn in western Europe have crossed the Atlantic unaided, in many (if not most) cases without stopping on the way. Yet we are far from being able to answer all the questions which are posed by these remarkable long-distance flights. Why, for example, do some species cross the Atlantic much more frequently than others? Why are a few birds recorded each year, and not many more, or many less? What factors determine the dates on which they cross? Why are most of the occurrences in the autumn? Why, despite the great advantage given to them by the prevail ing winds, are American waders only a little more numerous in Europe than European waders in North America? To dismiss the birds as "accidental vagrants", or to relate their occurrence to weather patterns, as have been attempted in the past, may answer some of these questions, but render the others still more acute. One fruitful approach to these problems is to compare the frequency of the various species in Europe with their abundance, migratory behaviour and ecology in North America. If the likelihood of occurrence in Europe should prove to be correlated with some particular type of migration pattern in North America this would offer an important clue as to the causes of trans atlantic vagrancy. In this paper some aspects of wader migration in North America will be discussed from this viewpoint.
