Twite The Twite (Linaria flavirostris) is a small brown passerine bird in the finch family Fringillidae. It is similar in size and shape to a Linnet, at 13 to 13.5 centimetres (5.1 to 5.3 in) long. It lacks the red head patch and breast shown by the Linnet and the Redpolls. It is brown streaked with black above and a pink rump. The underparts are buff to whitish, streaked with brown. The conical bill is yellow in winter and grey in summer. The call is a distinctive twit, from which its name derives and the song contains fast trills and twitters. Twites can form large flocks outside the breeding season, sometimes mixed with other finches on coasts and salt marshes. They feed mainly on seeds. The Twite breeds in northern Europe and across central Asia. Treeless moorland is favoured for breeding. It builds its nest in a bush, laying 5–6 light blue eggs. It is partially resident, but many birds migrate further south, or move to the coasts. It has declined sharply in parts of its range, notably Ireland. In the UK, the Twite is the subject of several research projects in the Pennines, the Scottish Highlands and the North Wales and Lancashire coastlines. Records show that the birds to the east of the Pennine hills move to the Southeast coast in winter and those to the west winter between Lancashire and the Hebrides. The Welsh population winters almost exclusively in Flintshire. In 1758 the Swedish naturalist Carl Linnaeus included the Twite in the 10th edition of his Systema Naturae under the binomial name Fringilla flavirostris. The genus name linaria is the Latin for a linen-weaver, from linum, "flax" and flavirostris means yellow-billed. The Twite and the closely related Linnets were at one time placed in the genus Carduelis but were moved to a separate genus Linaria based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences. There are 10 recognised subspecies. Photograph by G. Sparshott.

In: Animal Genetics ISBN: 978-1-60741-844-3 Editor: Leopold J. Rechi © 2009 Nova Science Publishers, Inc. Chapter 1 PHYLOGEOGRAPHY OF FINCHES AND SPARROWS Antonio Arnaiz-Villena*, Pablo Gomez-Prieto and Valentin Ruiz-del-Valle Department of Immunology, University Complutense, The Madrid Regional Blood Center, Madrid, Spain. ABSTRACT Fringillidae finches form a subfamily of songbirds (Passeriformes), which are presently distributed around the world. This subfamily includes canaries, goldfinches, greenfinches, rosefinches, and grosbeaks, among others. Molecular phylogenies obtained with mitochondrial DNA sequences show that these groups of finches are put together, but with some polytomies that have apparently evolved or radiated in parallel. The time of appearance on Earth of all studied groups is suggested to start after Middle Miocene Epoch, around 10 million years ago. Greenfinches (genus Carduelis) may have originated at Eurasian desert margins coming from Rhodopechys obsoleta (dessert finch) or an extinct pale plumage ancestor; it later acquired green plumage suitable for the greenfinch ecological niche, i.e.: woods. Multicolored Eurasian goldfinch (Carduelis carduelis) has a genetic extant ancestor, the green-feathered Carduelis citrinella (citril finch); this was thought to be a canary on phonotypical bases, but it is now included within goldfinches by our molecular genetics phylograms. Speciation events between citril finch and Eurasian goldfinch are related with the Mediterranean Messinian salinity crisis (5 million years ago). Linurgus olivaceus (oriole finch) is presently thriving in Equatorial Africa and was included in a separate genus (Linurgus) by itself on phenotypical bases. Our phylograms demonstrate that it is and old canary. Proposed genus Acanthis does not exist. Twite and linnet form a separate radiation from redpolls.

Assessing Population Changes from Disparate Data Sources: the Decline of the Twite Carduelis Flavirostris in England
Bird Conservation International (2009) 19:401–416. ª BirdLife International, 2009 doi:10.1017/S0959270909990086 Assessing population changes from disparate data sources: the decline of the Twite Carduelis flavirostris in England ANDRE´ F. RAINE, ANDREW F. BROWN, TATSUYA AMANO and WILLIAM J. SUTHERLAND Summary Conservationists often find it difficult to assess long-term population change in a species when the only data available are from disparate sources. This is especially the case when a range of survey methodologies and reporting units have been utilised and the results have been published in the ‘grey’ literature. Although the production of a cohesive assessment of change may be a daunting task, in such circumstances, a sound assessment of change is often possible. We illustrate this by considering the decline of the Twite Carduelis flavirostris in England. Whilst there is evidence of decline, it is widely dispersed and the losses have yet to be formally documented. To assess longer-term change, we reviewed information available in county avi- faunas and historical accounts of the status of the species throughout its former English range. Twite now only breed regularly in six of their 12 historical range counties, and in all of these six, the birds have declined markedly in abundance. We collated and analysed data drawn from a diverse range of surveys and county bird reports to assess more recent change and assessed contemporary distribution and abundance during our own surveys of breeding colonies in the South Pennines, an area supporting the last known nesting colonies in England. Combined, the data clearly indicate that the range and numbers of breeding Twite have declined considerably since the 1970s.

Simplified-ORL-2019-5.1-Final.Pdf
The Ornithological Society of the Middle East, the Caucasus and Central Asia (OSME) The OSME Region List of Bird Taxa, Part F: Simplified OSME Region List (SORL) version 5.1 August 2019. (Aligns with ORL 5.1 July 2019) The simplified OSME list of preferred English & scientific names of all taxa recorded in the OSME region derives from the formal OSME Region List (ORL); see www.osme.org. It is not a taxonomic authority, but is intended to be a useful quick reference. It may be helpful in preparing informal checklists or writing articles on birds of the region. The taxonomic sequence & the scientific names in the SORL largely follow the International Ornithological Congress (IOC) List at www.worldbirdnames.org. We have departed from this source when new research has revealed new understanding or when we have decided that other English names are more appropriate for the OSME Region. The English names in the SORL include many informal names as denoted thus '…' in the ORL. The SORL uses subspecific names where useful; eg where diagnosable populations appear to be approaching species status or are species whose subspecies might be elevated to full species (indicated by round brackets in scientific names); for now, we remain neutral on the precise status - species or subspecies - of such taxa. Future research may amend or contradict our presentation of the SORL; such changes will be incorporated in succeeding SORL versions. This checklist was devised and prepared by AbdulRahman al Sirhan, Steve Preddy and Mike Blair on behalf of OSME Council. Please address any queries to [email protected].

A Preliminary Assessment of the Scope and Scale of Illegal Killing and Taking of Wild Birds in the Arabian Peninsula, Iran and Iraq
A preliminary assessment of the scope and scale of illegal killing and taking of wild birds in the Arabian peninsula, Iran and Iraq ANNE-LAURE BROCHET, SHARIF JBOUR, ROBERT D SHELDON, RICHARD PORTER, VICTORIA R JONES, WAHEED AL FAZARI, OMAR AL SAGHIER, SAEED ALKHUZAI, LAITH ALI AL-OBEIDI, RICHARD ANGWIN, KORSH ARARAT, MIKE POPE, MOHAMMED Y SHOBRAK, MAÏA S WILLSON, SADEGH SADEGHI ZADEGAN & STUART H M BUTCHART Summary: High levels of illegal killing and taking of wild birds were recently reported for eastern Mediterranean countries, and anecdotal information from other countries of the Middle East suggests this may be a significant conservation issue for the whole region. We quantified the approximate scale and scope of this threat in the Arabian peninsula, Iran and Iraq, using a diverse range of data sources and incorporating expert knowledge. We estimate that at least 1.7–4.6 million (best esti- mate: 3.2 million) birds of at least 413 species may be killed or taken illegally each year in this region, many of them on migration. This is likely to be an underestimate as data were unavailable for parts of the region. The highest estimated country total, of 1.7 million birds, was for Saudi Arabia despite data being available only for the northern part of the country. Several species of global conservation concern were illegally killed or taken, including Marbled Teal Marmaronetta angustirostris, Common Pochard Aythya ferina and European Turtle-dove Streptopelia turtur (all classified by BirdLife International as Vulnerable on the global IUCN Red List). Of greater concern, Sociable Lapwing Vanellus gregarius (Critically Endangered) was also reported to be known or likely to be killed illegally each year in high numbers relative to its small population size.

Diversity and Endemism in Tidal-Marsh Vertebrates
Studies in Avian Biology No. 32:32-53 DIVERSITY AND ENDEMISM IN TIDAL-MARSH VERTEBRATES RUSSELL GREENBERG AND JESúS E. MALDONADO Abstract. Tidal marshes are distributed patcliily, predominantly along the mid- to high-latitude coasts of the major continents. The greatest extensions of non-arctic tidal marshes are found along the Atlantic and Gulf coasts of North America, but local concentrations can be found in Great Britain, northern Europe, northern Japan, northern China, and northern Korea, Argentina-Uruguay-Brazil, Australia, and New Zealand. We tallied the number of terrestrial vertebrate species that regularly occupy tidal marshes in each of these regions, as well as species or subspecies that are largely restricted to tidal marshes. In each of the major coastal areas we found 8-21 species of breeding birds and 13-25 species of terrestrial mammals. The diversity of tidal-marsh birds and mammals is highly inter-correlated, as is the diversity of species restricted to saltmarshes. These values are, in turn, correlated with tidal-marsh area along a coastline. We estimate approximately seven species of turtles occur in brackish or saltmarshes worldwide, but only one species is endemic and it is found in eastern North America. A large number of frogs and snakes occur opportunistically in tidal marshes, primarily in southeastern United States, particularly Florida. Three endemic snake taxa are restricted to tidal marshes of eastern North America as well. Overall, only in North America were we able to find documentation for multiple taxa of terrestrial vertebrates associated with tidal marshes. These include one species of mammal and two species of birds, one species of snake, and one species of turtle.
