Despite having a rich avifauna in Iran, limited number of studies have been conducted on lice fauna of wild birds in this region. This study was carried out to identify lice species of passerine birds in East of Iran. A total of 106 passerine birds of 37 species were captured. Their bodies were examined for lice infestation. Fifty two birds (49.05%) of 106 captured birds were infested. Overall 465 lice were collected from infested birds and 11 lice species were identified as follow: Brueelia chayanh on Common Myna (Acridotheres tristis), B.

Phylogeography of Finches and Sparrows
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.

In considering recently certain questions of ornithological nomenclature it became necessary to examine the works of Brisson and Linnaeus in con- siderable detail and this-examination finally led to a careful collation of Brisson's 'Ornithologia,' published in 1760, with the sixth, tenth, and twelfth editions of Linnaeus's 'Systema Naturae,' published respectively in 1748, 1758, and 1766. As every systematic ornithologist has had occasion to learn, Linnaeus's treatment of the class Aves was based on very imperfect knowledge of the suabject. As is well-known, this great systematist was primarily a botanist, secondarily a zoologist, and only incidentally a mammalogist and ornithol- ogist.

Checklist of the birds of New Zealand, Norfolk and Macquarie Islands, and the Ross Dependency, Antarctica. 4th edition. Wellington, Te Papa Press and Ornithological Society of New Zealand. Pages 275, 279 & 319-320. Order PASSERIFORMES: Passerine (Perching) Birds See Christidis & Boles (2008) for a review of recent studies relevant to the higher-level systematics of the passerine birds. Suborder PASSERES (or POLYMYODI): Oscines (Songbirds) The arrangement of songbirds in the 1970 Checklist (Checklist Committee 1970) was based on the premise that the species endemic to the Australasian region were derived directly from Eurasian groups and belonged in Old World families (e.g. Gerygone and Petroica in Muscicapidae). The 1990 Checklist (Checklist Committee 1990) followed the Australian lead in allocating various native songbirds to their own Australasian families (e.g. Gerygone to Acanthizidae, and Petroica to Eopsaltriidae), but the sequence was still based largely on the old Peters-Mayr arrangement. Since the late 1980s, when the 1990 Checklist was finalised, evidence from molecular biology, especially DNA studies, has shown that most of the Australian and New Zealand endemic songbirds are the product of a major Australasian radiation parallel to the radiation of songbirds in Eurasia and elsewhere. Many superficial morphological and ecological similarities between Australasian and Eurasian songbirds are the result of convergent evolution. Sibley & Ahlquist (1985, 1990) and Sibley et al. (1988) recognised a division of the songbirds into two groups which were called Corvida and Passerida (Sibley & Ahlquist 1990).

On the Advantages of Crossed Mandibles: an Experimental Approach
IBIS 130: 288-293 On the advantages of crossed mandibles: an experimental approach CRAIG W. BENKMAN* Department of Biological Sciences, State Uniwersity of New York at Albany, 1400 Washington Avenue, Albany, New York 12222, USA Accepted 20 November 1986 The importance of the crossed mandibles to crossbills for foraging on conifer cones was studied by removing most of the crossed portion of the mandibles of two Red Crossbills L. curuirortra. The foraging rate of these two bill-altered crossbills on the cones of three species of conifers was compared to their rates prior to bill alteration and to two controls. The mandible crossing proved essential for extracting seeds from closed cones. However, as cones open the bill crossing becomes less critical. The mandible crossing appears to be one of several adaptationsof crossbills that have extended the period during which conifer seeds can be exploited effectively. The functions of morphological structures can often be understood by detailed observations of organisms. However, a difficulty with ascribing a function to a structure by observation alone is that different observers often come to different conclusions. Experimental investigations of function are desirable but are often either difficult or trivial. For example, removing a bird’s leg would make perching or terrestrial locomotion impossible or awkward. In some cases, however, slight modification of structures may provide a means for studying a structure’s utility. One striking example of the difficulty of attributing a function to a structure by observation alone is the crossed mandibles of crossbills Loxia. There have been many opinions as to the function of the mandible crossing ranging from those suggesting no adaptive value to those suggesting a specific adaptive function.

Seed Handling Ability, Bill Structure, and the Cost of Specialization for Crossbills
SEED HANDLING ABILITY, BILL STRUCTURE, AND THE COST OF SPECIALIZATION FOR CROSSBILLS CRAIG W. BENKMAN • Departmentof BiologicalSciences, State University of New Yorkat Albany, 1400Washington Avenue, Albany, New York12222 USA AssT•cT.--Crossbills(Loxia) are specialized to extractand handle seeds from conifercones. I evaluatedthe ability of crossbillsto handlenonconifer seeds by comparingseed handling efficiencieswith other carduelinefinches. For all seedsizes, crossbills required seed encounter ratesor seedabundances 2-3 times greaterthan other speciesto meet their daily energy requirements.Consequently, crossbills may suffer high mortality during conifer cone failures. Crossbillsare inefficientat meetingtheir energydemands on nonconiferseeds because of their narrowmandibles, lowered horny palate,and large body size.The narrow mandibles enablecrossbills to efficientlyextract seeds from conifer cones and the loweredpalate enables them to handle small seedsrapidly. Crossbillshave evolvedlarger bills, and associated musculatureand bodymass, to providethe power necessaryto separatecone scales. Some of the increasein bodymass, however, may counterbalance the largebills to improvepredator evasion. Received27 October1987, accepted17 June1988.

Advances in the Study of Irruptive Migration
Advances in the study of irruptive migration Ian Newton1 Newton I. 2006. Advances in the study of irruptive migration. Ardea 94(3): 433–460. This paper discusses the movement patterns of two groups of birds which are generally regarded as irruptive migrants, namely (a) boreal finches and others that depend on fluctuating tree-fruit crops, and (b) owls and others that depend on cyclically fluctuating rodent popula- tions. Both groups specialise on food supplies which, in particular regions, fluctuate more than 100-fold from year to year. However, seed- crops in widely separated regions may fluctuate independently of one another, as may rodent populations, so that poor food supplies in one region may coincide with good supplies in another. If individuals are to have access to rich food supplies every year, they must often move hun- dreds or thousands of kilometres from one breeding area to another. In years of widespread food shortage (or high numbers relative to food supplies) extending over many thousands or millions of square kilome- tres, large numbers of individuals migrate to lower latitudes, as an ‘irruptive migration’. For these reasons, the distribution of the popula- tion, in both summer and winter, varies greatly from year to year. In irruptive migrants, in contrast to regular migrants, site fidelity is poor, and few individuals return to the same breeding areas in succes- sive years (apart from owls in the increase phase of the cycle). Moreover, ring recoveries and radio-tracking confirm that the same indi- viduals can breed in different years in areas separated by hundreds or thousands of kilometres.
