The Generic Distinction of Pied Woodpeckers
THE GENERIC DISTINCTION OF PIED WOODPECKERS M. RALPH BROWNING, 170 JacksonCreek Drive, Jacksonville,Oregon 97530 ABSTRACT: The ten speciesof New World four-toedwoodpeckers (scalaris, nuttallii, pubescens, villosus, stricklandi, arizonae, borealis, albolarvatus, lignarius,and m ixtusand the two borealthree-toed species (arcticus and tridactylus), currentlycombined in the genusPicoides, differ, in additionto the numberof toes,in modificationsof the skull,ribs, the belly of the pubo-ischio-femoralismuscle, head plumage,and behavior. I recommendthat the genericname Dryobates be reinstituted for the New World four-toedwoodpeckers. There are three generalmorphological groups of pied woodpeckers,a groupof nine four-toedspecies of the New World, a groupof 22 four-toed speciesof the Old World, and a groupof two three-toedspecies straddling bothregions. ! referto thesegroups of piedwoodpeckers beyond as the New World,Old World,and three-toedgroups. The three-toedspecies have long beenin the genusPicoides Lac•p•de, 1799, but the four-toedgroups have been combinedat the genericlevel in differentways. All four-toedpied woodpeckerswere long includedin the genusDryobates Boie, 1826, later changed to Dendrocopos Koch, 1816 an earlier name (Voous 1947, A.O.U. 1947, Peters 1948). Despite the differencein number of toes, Dendrocoposwas combined with Picoidesbecause of generalsimilarities in anatomy (Delacour 1951, Short 1971a), plumage and behavior (Short 1974a), and vocalizations(Winkler and Short 1978). The A.O.U (1976) followedthis mergerof the genera.On the basisof skeletalcharacters Rea (1983) was skepticalof the merger,but he did not providedetails. On the otherhand, Ouellet(1977), concludingthat the two generadiffer in external morphologyand some behaviors and vocalizations, separated the Old World four-toedwoodpeckers in Dendrocoposand three-toedand New World four-toedwoodpeckers in Picoides.The A.O.U. -
(Dendrocopos Syriacus) and Middle Spotted Woodpecker (Dendrocoptes Medius) Around Yasouj City in Southwestern Iran
Archive of SID Iranian Journal of Animal Biosystematics (IJAB) Vol.15, No.1, 99-105, 2019 ISSN: 1735-434X (print); 2423-4222 (online) DOI: 10.22067/ijab.v15i1.81230 Comparison of nest holes between Syrian Woodpecker (Dendrocopos syriacus) and Middle Spotted Woodpecker (Dendrocoptes medius) around Yasouj city in Southwestern Iran Mohamadian, F., Shafaeipour, A.* and Fathinia, B. Department of Biology, Faculty of Science, Yasouj University, Yasouj, Iran (Received: 10 May 2019; Accepted: 9 October 2019) In this study, the nest-cavity characteristics of Middle Spotted and Syrian Woodpeckers as well as tree characteristics (i.e. tree diameter at breast height and hole measurements) chosen by each species were analyzed. Our results show that vertical entrance diameter, chamber vertical depth, chamber horizontal depth, area of entrance and cavity volume were significantly different between Syrian Woodpecker and Middle Spotted Woodpecker (P < 0.05). The average tree diameter at breast height and nest height between the two species was not significantly different (P > 0.05). For both species, the tree diameter at breast height and nest height did not significantly correlate. The directions of nests’ entrances were different in the two species, not showing a preferentially selected direction. These two species chose different habitats with different tree coverings, which can reduce the competition between the two species over selecting a tree for hole excavation. Key words: competition, dimensions, nest-cavity, primary hole nesters. INTRODUCTION Woodpeckers (Picidae) are considered as important excavator species by providing cavities and holes to many other hole-nesting species (Cockle et al., 2011). An important part of habitat selection in bird species is where to choose a suitable nest-site (Hilden, 1965; Stauffer & Best, 1982; Cody, 1985). -

Our flight in from the UK was delayed so no time for any real birding on this first day of our “Chilled Birding Tour”. Our local guide Tijan and our ground crew met us at the airport. We piled into Tijan’s well used minibus as Little Swifts and Yellow-billed Kites flew above us. A short drive took us to our lovely small boutique hotel complete with pool and lovely private gardens, we were going to enjoy staying here. Having settled in we all met up for a pre-dinner drink in the warmth of an African evening. The food was delicious, and we chatted excitedly about the birds that lay ahead on this nine- day trip to The Gambia, the first time in West Africa for all our guests. At first light we were exploring the gardens of the hotel and enjoying the warmth after leaving the chilly UK behind. Both Red-eyed and Laughing Doves were easy to see and a flash of colour announced the arrival of our first Beautiful Sunbird, this tiny gem certainly lived up to its name! A bird flew in landing in a fig tree and again our jaws dropped, a Yellow-crowned Gonolek what a beauty! Shocking red below, black above with a daffodil yellow crown, we were loving Gambian birds already. -

Anatomical Evidence for Phylogenetic Relationships Among Woodpeckers
ANATOMICAL EVIDENCE FOR PHYLOGENETIC RELATIONSHIPS AMONG WOODPECKERS WILLIAM R. GOODGE ALT•tOUCr•the functionalanatomy of woodpeckershas long been a subjectof interest,their internal anatomyhas not been usedextensively for determiningprobable phylogeneticrelationships within the family. In part this is probablydue to the reluctanceto use highly adaptivefea- tures in phylogeneticstudies becauseof the likelihood of convergent evolution. Bock (1967) and othershave pointedout that adaptivehess in itself doesnot rule out taxonomicusefulness, and that the highly adaptivefeatures will probablybe the oneshaving conspicuous anatomical modifications,and Bock emphasizesthe need for detailedstudies of func- tion beforeusing featuresin studiesof phylogeny.Although valuable, functionalconclusions are often basedon inferencesnot backed up by experimentaldata. As any similaritybetween species is possiblydue to functionalconvergence, I believewhat is neededmost is detailedstudy of a numberof featuresin order to distinguishbetween similarities re- sultingfrom convergenceand thosebased on phylogenticrelationship. Simplestructures are not necessarilymore primitive and morphological trendsare reversible,as Mayr (1955) has pointedout. Individual varia- tion may occur and various investigatorsmay interpret structuresdif- ferently. Despite these limitations,speculation concerning phylogeny will continuein the future,and I believethat it shouldbe basedon more, rather than fewer anatomical studies.

Systematic and Taxonomic Issues Concerning Some East African Bird Species, Notably Those Where Treatment Varies Between Authors
Scopus 34: 1–23, January 2015 Systematic and taxonomic issues concerning some East African bird species, notably those where treatment varies between authors Donald A. Turner and David J. Pearson Summary The taxonomy of various East African bird species is discussed. Fourteen of the non- passerines and forty-eight of the passerines listed in Britton (1980) are considered, with reference to treatments by various subsequent authors. Twenty-three species splits are recommended from the treatment in Britton (op. cit.), and one lump, the inclusion of Jackson’s Hornbill Tockus jacksoni as a race of T. deckeni. Introduction With a revision of Britton (1980) now nearing completion, this is the first of two pa- pers highlighting the complexities that surround some East African bird species. All appear in Britton in one form or another, but since that landmark publication our knowledge of East African birds has increased considerably, and with the advances in DNA sequencing, our understanding of avian systematics and taxonomy is con- tinually moving forward. A tidal wave of phylogenetic studies in the last decade has revolutionized our understanding of the higher-level relationships of birds. Taxa pre- viously regarded as quite distantly related have been brought together in new clas- sifications and some major groups have been split asunder (Knox 2014). As a result we are seeing the familiar order of families and species in field guides and checklists plunged into turmoil. The speed at which molecular papers are being published continues at an unprec- edented rate. We must remember, however, that while many molecular results may indicate a relationship, they do not necessarily prove one. -

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]. -
