WALKING WATERBIRDS unmistakable, elegant wader; no similar species in Chile SHOREBIRDS For ID purposes there are 3 basic types of shorebirds: 6 ‘unmistakable’ species (avocet, stilt, oystercatchers, sheathbill; pp. 89–91); 13 plovers (mainly visual feeders with stop- start feeding actions; pp. 92–98); and 22 sandpipers (mainly tactile feeders, probing and pick- ing as they walk along; pp. 99–109). Most favor open habitats, typically near water. Different species readily associate together, which can help with ID—compare size, shape, and behavior of an unfamiliar species with other species you know (see below); voice can also be useful. 2 1 5 3 3 3 4 4 7 6 6 Andean Avocet Recurvirostra andina 45–48cm N Andes.

Ecological Landscape Analysis of Clare Ecodistrict 730 40
Ecological Landscape Analysis of Clare Ecodistrict 730 40 © Crown Copyright, Province of Nova Scotia, 2014. Ecological Landscape Analysis, Ecodistrict 730: Clare Prepared by the Nova Scotia Department of Natural Resources Authors: Western Region DNR staff ISBN 978-1-55457-598-5 This report, one of 38 for the province, provides descriptions, maps, analysis, photos and resources of the Clare Ecodistrict that can help landowners and planners understand important characteristics of the landscape. The report details the main elements in the ecodistrict and, of particular interest to woodland owners, vegetation types within forest stands. Ecological Landscape Analysis (ELA) is a first step in developing an ecosystem approach to managing resource values at a landscape level. It supports planning by landowners wanting to understand how their land fits into the landscape ecosystem. Additional direction will be provided by a landscape planning guide, and internet-based inventory update system, both of which are currently under development. The ELAs were analyzed and written from 2005 – 2009. They provide baseline information for this period in a standardized framework of ecosystem mapping and data summary designed to support future data updates, forecasts and trends. This document includes Part 1 – Learning about what makes this ecodistrict distinctive – and Part 2 – How woodland owners can apply landscape concepts to their woodland. Part 3 – Greater detail for forest planners and analysts – will be available on request by contacting DNR officials -
Rejection Behavior by Common Cuckoo Hosts Towards Artificial Brood Parasite Eggs
REJECTION BEHAVIOR BY COMMON CUCKOO HOSTS TOWARDS ARTIFICIAL BROOD PARASITE EGGS ARNE MOKSNES, EIVIN ROSKAFT, AND ANDERS T. BRAA Departmentof Zoology,University of Trondheim,N-7055 Dragvoll,Norway ABSTRACT.--Westudied the rejectionbehavior shown by differentNorwegian cuckoo hosts towardsartificial CommonCuckoo (Cuculus canorus) eggs. The hostswith the largestbills were graspejectors, those with medium-sizedbills were mostlypuncture ejectors, while those with the smallestbills generally desertedtheir nestswhen parasitizedexperimentally with an artificial egg. There were a few exceptionsto this general rule. Becausethe Common Cuckooand Brown-headedCowbird (Molothrus ater) lay eggsthat aresimilar in shape,volume, and eggshellthickness, and they parasitizenests of similarly sizedhost species,we support the punctureresistance hypothesis proposed to explain the adaptivevalue (or evolution)of strengthin cowbirdeggs. The primary assumptionand predictionof this hypothesisare that somehosts have bills too small to graspparasitic eggs and thereforemust puncture-eject them,and that smallerhosts do notadopt ejection behavior because of the heavycost involved in puncture-ejectingthe thick-shelledparasitic egg. We comparedour resultswith thosefor North AmericanBrown-headed Cowbird hosts and we found a significantlyhigher propor- tion of rejectersamong CommonCuckoo hosts with graspindices (i.e. bill length x bill breadth)of <200 mm2. Cuckoo hosts ejected parasitic eggs rather than acceptthem as cowbird hostsdid. Amongthe CommonCuckoo hosts, the costof acceptinga parasiticegg probably alwaysexceeds that of rejectionbecause cuckoo nestlings typically eject all hosteggs or nestlingsshortly after they hatch.Received 25 February1990, accepted 23 October1990.

Wader Study 128(2): xxx–xxx. Hudsonian Whimbrel Numenius hudsonicus are rapidly declining and understanding Keywords their use of migratory staging sites is a top research priority. Nocturnal roosts are site fidelity an essential, yet often overlooked component of staging sites due to their apparent rarity, inaccessibility, and inconspicuousness. The coast of Georgia and stopover South Carolina is one of two known important staging areas for Atlantic coast staging area Whimbrel during spring migration. Within this critical staging area, we discovered the largest known Whimbrel nocturnal roost in the Western Hemisphere at population estimate Deveaux Bank, South Carolina. Surveys in 2019 and 2020 during peak spring management migration revealed that Deveaux Bank supports at least 19,485 roosting Whimbrel, conservation which represents approximately 49% of the estimated eastern population of Whimbrel and 24% of the entire North American population. -

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. -
HUDSONIAN WHIMBREL at FAIR ISLE by KENNETH WILLIAMSON and VALERIE M
HUDSONIAN WHIMBREL AT FAIR ISLE BY KENNETH WILLIAMSON and VALERIE M. THOM (Fair Isle Bird Observatory) WHILST bird-watching over an area of close-cropped grassland at the south end of Fair Isle on 27th May 1955 the writers, together with visitors to the Bird Observatory, disturbed a party of half-a- dozen Whimbrels (Numenius phmopus). As they flew off, V.M.T. remarked that one of the birds was without a white rump. During the remainder of the day, and on the 28th, we kept this party under observation, often at very close quarters from the cover of dry-stone dykes, and were able to satisfy ourselves that the odd bird was an example of the American race, the Hudson- ian Whimbrel (Numenius ph. hudsonicus)—called Hudsonian Curlew in the A.O.U. Checklist. The bird was distinctly smaller than its companions (some of the observers estimated from one-third to one-quarter smaller) and of slenderer build and sleeker appearance. The disparity in size was most obvious when the birds were in flight. The head- markings were similar to those of the European Whimbrel but were more pronounced, due to the paler colour of the cheeks and more complete eye-stripe. In flight, the bird offered a distinctive pattern of dark brown primaries contrasting with paler brown, buff-mottled secondaries and coverts, and a warmer brown mantle, rump and tail. The last, in fact, appeared in some lights to have a russet tinge. The bill was similar in length to the Whirnbrel's, blackish in colour, and strongly decurved over the distal half. -
New Caledonia, Fiji & Vanuatu
Field Guides Tour Report Part I: New Caledonia Sep 5, 2011 to Sep 15, 2011 Phil Gregory The revamped tour was a little later this year and it seemed to make some things a bit easier, note how well we did with the rare Crow Honeyeater, and Kagu was as ever a standout. One first-year bird was rewarded with a nice juicy scorpion that our guide found, and this really is a fabulous bird to see, another down on Harlan's famiy quest, too, as an added bonus to what is a quite unique bird. Cloven-feathered Dove was also truly memorable, and watching one give that strange, constipated hooting call was fantastic and this really is one of the world's best pigeons. Air Calin did their best to make life hard with a somewhat late flight to Lifou, and I have to say the contrast with the Aussie pilots in Vanuatu was remarkable -- these French guys must still be learning as they landed the ATR 42's so hard and had to brake so fiercely! Still, it all worked out and the day trip for the Ouvea Parakeet worked nicely, whilst the 2 endemic white-eyes on Lifou were got really early for once. Nice food, an interesting Kanak culture, with a trip to the amazing Renzo Piano-designed Tjibaou Cultural Center also feasible this The fantastic Kagu, star of the tour! (Photo by guide Phil year, and a relaxed pace make this a fun birding tour with some Gregory) terrific endemic birds as a bonus. My thanks to Karen at the Field Guides office for hard work on the complex logistics for this South Pacific tour, to the very helpful Armstrong at Arc en Ciel, Jean-Marc at Riviere Bleue, and to Harlan and Bart for helping me with my bags when I had a back problem. -

MORPHOLOGICAL and ECOLOGICAL EVOLUTION in OLD and NEW WORLD FLYCATCHERS a Dissertation Presented to the Faculty of the College O
MORPHOLOGICAL AND ECOLOGICAL EVOLUTION IN OLD AND NEW WORLD FLYCATCHERS A dissertation presented to the faculty of the College of Arts and Sciences of Ohio University In partial fulfillment of the requirements for the degree Doctor of Philosophy Clay E. Corbin August 2002 This dissertation entitled MORPHOLOGICAL AND ECOLOGICAL EVOLUTION IN OLD AND NEW WORLD FLYCATCHERS BY CLAY E. CORBIN has been approved for the Department of Biological Sciences and the College of Arts and Sciences by Donald B. Miles Associate Professor, Department of Biological Sciences Leslie A. Flemming Dean, College of Arts and Sciences CORBIN, C. E. Ph.D. August 2002. Biological Sciences. Morphological and Ecological Evolution in Old and New World Flycatchers (215pp.) Director of Dissertation: Donald B. Miles In both the Old and New Worlds, independent clades of sit-and-wait insectivorous birds have evolved. These independent radiations provide an excellent opportunity to test for convergent relationships between morphology and ecology at different ecological and phylogenetic levels. First, I test whether there is a significant adaptive relationship between ecology and morphology in North American and Southern African flycatcher communities. Second, using morphological traits and observations on foraging behavior, I test whether ecomorphological relationships are dependent upon locality. Third, using multivariate discrimination and cluster analysis on a morphological data set of five flycatcher clades, I address whether there is broad scale ecomorphological convergence among flycatcher clades and if morphology predicts a course measure of habitat preference. Finally, I test whether there is a common morphological axis of diversification and whether relative age of origin corresponds to the morphological variation exhibited by elaenia and tody-tyrant lineages.
