  • The Mysteries of Bird Migration – Still Much to Be Learnt
    The mysteries of bird migration – still much to be learnt Franz Bairlein ABSTRACT Bird ringing has unveiled many mysteries of avian migrations, notably routes and destinations. However, there is still much to be explored by the use of ringing and other marking techniques. Satellite tracking, geolocation and global positioning systems are new tools, as well as particular chemical and molecular markers which appear to be very useful in the study of bird migration by delineating origin of birds and connectivity between breeding and non-breeding grounds. Understanding of bird migrations also gained much from captive studies about the internal mechanisms in the control of bird migration, but we still lack knowledge about external factors, such as food availability, weather, competitors, parasites or diseases.This paper summarises ongoing studies on Northern Wheatears Oenanthe oenanthe to illustrate the benefit of such an integrated approach. Future migration research must aim much more at comparative research and a more integrated approach at various spatial and temporal scales, and linking various sub-disciplines. It is also important to realise that migration is only one part of the life-cycle of a migrating species.Thus, linking migration and breeding is another future challenge, for both basic science and conservation of migratory birds. or centuries, the seasonal arrival and The study of bird migration by ringing departure of bird species to and from Our knowledge of bird migration improved Ftheir breeding grounds remained a dramatically with the development of bird mystery. Although these events were described ringing, first practised by the Danish school by early observers such as the wall and floor teacher Hans Christian Cornelius Mortensen in painters of ancient Egypt, Aristotle and the 1899 (Jespersen & Tåning 1950; Bairlein 2001).

  • Bird Flu Research at the Center for Tropical Research by John Pollinger, CTR Associate Director
    Center for Tropical Research October 2006 Bird Flu Research at the Center for Tropical Research by John Pollinger, CTR Associate Director Avian Influenza Virus – An Overview The UCLA Center for Tropical Research (CTR) is at the forefront of research and surveillance efforts on avian influenza virus (bird flu or avian flu) in wild birds. CTR has led avian influenza survey efforts on migratory landbirds in both North America and Central Africa since spring 2006. We have recently been funded by the National Institutes of Health (NIH) to conduct a large study in North, Central, and South America on the effects of bird migration and human habitat disturbance on the distribution and transmission of bird flu. These studies take advantage of our unique collaboration with the major bird banding station networks in the Americas, our extensive experience in avian field research in Central Africa, and UCLA’s unique resources and expertise in infectious diseases though the UCLA School of Public Health and its Department of Epidemiology. CTR has ongoing collaborations with four landbird monitoring networks: the Monitoring Avian Productivity and Survivorship (MAPS) network, the Monitoring Avian Winter Survival (MAWS) network, and the Monitoreo de Sobrevivencia Invernal - Monitoring Overwintering Survival (MoSI) network, all led by the Institute for Bird Populations (IBP), and the Landbird Migration Monitoring Network of the Americas (LaMMNA), led by the Redwood Sciences Laboratory (U.S. Forest Service). Bird flu has shot to the public’s consciousness with the recent outbreaks of a highly virulent subtype of avian influenza A virus (H5N1) that has recently occurred in Asia, Africa, and Europe.

  • AERC Wplist July 2015
    AERC Western Palearctic list, July 2015 About the list: 1) The limits of the Western Palearctic region follow for convenience the limits defined in the “Birds of the Western Palearctic” (BWP) series (Oxford University Press). 2) The AERC WP list follows the systematics of Voous (1973; 1977a; 1977b) modified by the changes listed in the AERC TAC systematic recommendations published online on the AERC web site. For species not in Voous (a few introduced or accidental species) the default systematics is the IOC world bird list. 3) Only species either admitted into an "official" national list (for countries with a national avifaunistic commission or national rarities committee) or whose occurrence in the WP has been published in detail (description or photo and circumstances allowing review of the evidence, usually in a journal) have been admitted on the list. Category D species have not been admitted. 4) The information in the "remarks" column is by no mean exhaustive. It is aimed at providing some supporting information for the species whose status on the WP list is less well known than average. This is obviously a subjective criterion.

  • Identification of Isabelline Wheatear, Desert Warbler and Three Phylloscopus Warblers Alan R
    Identification of Isabelline Wheatear, Desert Warbler and three Phylloscopus warblers Alan R. Kitson i, 3, o, ii2 & o: the British and Irish records totals of each of these five mainly Asiatic species he background to my observations in Mongolia was detailed earlier T(Kitson 1978). This paper covers five more species which have occurred or might occur as vagrants to western Europe. Isabelline Wheatear Oenanthe isabellina From mid April onwards, this wheatear breeds very commonly on the grassy steppes of Mongolia and half-heard snatches of its whistling, highly mimetic song were always causing me to look around, now for a wader, now for a tern. I became very familiar with it. Having compared my notes with the texts of modern field guides, I wish to emphasise several characters that seem to me to be incompletely appreciated, particularly in the all-important differentiation (to observers in Europe) of Isabelline from the pale morphs of the Greenland race of Wheatear 0. oenanthe leucorrhoa. First, it is important to recognise the differences in rump- and tail- pattern of wheatears. Fig. 1 shows these for five species. To my eyes, it is the tail-pattern and tail-shape of Isabelline which form the most immediate distinctions in the field from Wheatear. In that species, the tail-pattern is essentially an inverted black T abutting a white base; the a bed Fig. 1. Field appearance of tails of five wheatears Oenanthe.

These small, fragmented populations are fragile due to demographic and genetic factors, whereas immigration can enhance their long-term viability. Previously, we showed that high philopatry affected the local dynamics of three small and remnant subpopulations of Northern Wheatears in The Netherlands. Here, we show that these three populations together with an additional larger population in the European lowlands are highly genetically differentiated based on 22 microsatellite markers. In contrast, we found no evidence for differentiation using two mitochondrial DNA markers. An IMa2 analysis indicates that gene flow has occurred regularly among our sampled populations. As immigration of colour-ringed birds among our sampled populations is rare at best, our results suggest that the populations have recently become isolated from one another. Low dispersal rates in highly mobile birds may occur when suitable habitat becomes highly fragmented, and will accentuate stochastic demographic processes and inbreeding, both reducing population viability.
