Salt exploitation has cre- ated a geometrical artificial landscape in which we investigated factors influencing spatial distribution and breeding success of this species using a Geographical Information System. We compared data for four sites in these salt-pans, for three zones in the most densely populated site, and for 2500 m2 grid cells defined for this same site. This study showed the influence of (1) the level of salt exploitation activity, (2) the density of bank intersections, (3) the extent of area covered by Suaeda vera bushes and (4) the structural heterogeneity. The continued management of these salt-pans enhanced bird breeding success. Thus, traditional salt exploitation contributes directly to the conservation of bluethroat, considered as an endangered species in Europe. # 2002 Elsevier Science Ltd. All rights reserved.

Newsletter No 31
P O Box 93, Wakkerstroom 2480 Cell Number 0822556778 E-Mail: [email protected] NEWSLETTER NUMBER 31– FEBRUARY 2015 Phragmites australis is a Perennial Grass that grows in the wetlands of the temperate and tropical regions of the world on all continents except Antarctica. It is thought to have originated from Phyrgia in Asia Minor. In Europe it is rarely invasive, it is even used as an ornamental plant, but everywhere else can be a major problem. It does have its uses; thatching, making arrows, youngsters eat it and it can be dried and ground into a fine powder that, when moistened, can be toasted like marsh mallows. In Egypt it is used for making a flute-like musical instrument, maybe that‟s why another name here in South Africa is Fluitjiesriet. Its most important use is for bioremediation where excess nutrients and pollutants are removed from dirty water and sewage pond waste water by bacterial action on the Phragmites roots and leaf litter. The downside is that it is highly invasive WoF operatives hard at work plant that crowds-out other wetland plant species reducing overall plant, animal and bird diversity. It can spread at the rate of 5m per year from horizontal runners, rhizomes up to 10m long that produce a new shoot every 300mm. It is allelopathic i.e. it releases toxins from its roots that stop the growth of other plants. It out-competes native plants for nutrients, water and sunlight. The outcome – a 3m plus tall, handsome plant that forms a deceptively beautiful monoculture! Phragmites is difficult to control and impossible to eradicate entirely. -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

Thailand Highlights 14Th to 26Th November 2019 (13 Days)
Thailand Highlights 14th to 26th November 2019 (13 days) Trip Report Siamese Fireback by Forrest Rowland Trip report compiled by Tour Leader: Forrest Rowland Trip Report – RBL Thailand - Highlights 2019 2 Tour Summary Thailand has been known as a top tourist destination for quite some time. Foreigners and Ex-pats flock there for the beautiful scenery, great infrastructure, and delicious cuisine among other cultural aspects. For birders, it has recently caught up to big names like Borneo and Malaysia, in terms of respect for the avian delights it holds for visitors. Our twelve-day Highlights Tour to Thailand set out to sample a bit of the best of every major habitat type in the country, with a slight focus on the lush montane forests that hold most of the country’s specialty bird species. The tour began in Bangkok, a bustling metropolis of winding narrow roads, flyovers, towering apartment buildings, and seemingly endless people. Despite the density and throng of humanity, many of the participants on the tour were able to enjoy a Crested Goshawk flight by Forrest Rowland lovely day’s visit to the Grand Palace and historic center of Bangkok, including a fun boat ride passing by several temples. A few early arrivals also had time to bird some of the urban park settings, even picking up a species or two we did not see on the Main Tour. For most, the tour began in earnest on November 15th, with our day tour of the salt pans, mudflats, wetlands, and mangroves of the famed Pak Thale Shore bird Project, and Laem Phak Bia mangroves. -
Territoriality As a Paternity Guard in the European Robin, Erithacus Rubecula
ANIMAL BEHAVIOUR, 2000, 60, 165–173 doi:10.1006/anbe.2000.1442, available online at http://www.idealibrary.com on ARTICLES Territoriality as a paternity guard in the European robin, Erithacus rubecula JOE TOBIAS & NAT SEDDON Department of Zoology, University of Cambridge (Received 29 June 1999; initial acceptance 29 July 1999; final acceptance 18 March 2000; MS. number: 6273) To investigate the relative importance of paternity defences in the European robin we used behavioural observations, simulated intrusions and temporary male removal experiments. Given that paired males did not increase their mate attendance, copulation rate or territory size during the female’s fertile period, the most frequently quoted paternity assurance strategies in birds were absent. However, males with fertile females sang and patrolled their territories more regularly, suggesting that territorial motivation and vigilance were elevated when the risk of cuckoldry was greatest. In addition, there was a significant effect of breeding period on response to simulated intrusions: residents approached and attacked freeze-dried mounts more readily in the fertile period. During 90-min removals of the pair male in the fertile period, neighbours trespassed more frequently relative to prefertile and fertile period controls and appeared to seek copulations with unattended females. When replaced on their territories, males immediately increased both song rate and patrolling rate in comparison with controls. We propose that male robins sing to signal their presence, and increase their territorial vigilance and aggression in the fertile period to protect paternity. 2000 The Association for the Study of Animal Behaviour Despite the apparent social monogamy of the majority of Thryothorus nigricapillus: Levin 1996). -
Rejection Behavior by Common Cuckoo Hosts Towards Artificial Brood Parasite Eggs

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.

The most complex songs contain as many as five or six different trills and single notes. The song of the Siberian Blue Robin most closely resembles that of the Indian Blue Robin L. brunnea. The individual repertoires of Siberian Blue Robin, Common Nightingale L. megarhynchos and Thrush Nightingale L. luscinia contain groups of mutually associ- ated song types that are sung usually one after another. The Siberian Blue Robin and the Common Nightingale perform them in a varying sequence, while Thrush Nightin- gale predominantly uses a fixed sequence of song types.

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.

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. -
Taxonomic Status of Blackthroat Calliope Obscura and Firethroat C
FORKTAIL 29 (2013): 94–99 Taxonomic status of Blackthroat Calliope obscura and Firethroat C. pectardens PER ALSTRÖM, GANG SONG, RUIYING ZHANG, XUEBIN GAO, PAUL I. HOLT, URBAN OLSSON & FUMIN LEI The Chinese endemic breeders Blackthroat Calliope obscura and Firethroat C. pectardens are two of the world’s rarest and least known ‘chats’ (Muscicapidae). They have been considered colour morphs of the same species (Firethroat, by priority), although they are nowadays usually treated as separate species. The taxonomic status of these two taxa is here investigated based on analyses of mitochondrial and nuclear DNA, vocalisations and reassessed distributions. Phylogenetic analysis confirms that they are sisters. Their genetic divergence (cytochrome b 6.4%, GTR+Γ+I corrected) is comparable to several other species pairs of ‘chats’. Discriminant function analysis of songs correctly classified 88% of the recordings. The breeding ranges appear to be mainly parapatric. Based on congruent differences in morphology, songs and molecular markers, it is concluded that Blackthroat and Firethroat are appropriately treated as separate species. INTRODUCTION and songs, and the distributions of the two species are reviewed. It is concluded that Blackthroat and Firethroat are best treated as The Blackthroat Calliope obscura and Firethroat C. pectardens are separate species. two of the world’s rarest and least known ‘chats’.
