Spatial Behaviour and Density of Three Species of Long-Distance Migrants Wintering in a Disturbed and Non-Disturbed Woodland in Northern Ghana
Bird Conservation International (2018) 28:59–72. © BirdLife International, 2017 doi:10.1017/S0959270917000132 Spatial behaviour and density of three species of long-distance migrants wintering in a disturbed and non-disturbed woodland in northern Ghana MIKKEL WILLEMOES, ANDERS P. TØTTRUP, MATHILDE LERCHE-JØRGENSEN, ERIK MANDRUP JACOBSEN, ANDREW HART REEVE and KASPER THORUP Summary Changes in land-use and climate are threatening migratory animals worldwide. In birds, declines have been widely documented in long-distance migrants. However, reasons remain poorly under- stood due to a lack of basic information regarding migratory birds’ ecology in their non-breeding areas and the effects of current environmental pressures there. We studied bird densities, spatial and territorial behaviour and habitat preference in two different habitat types in northern Ghana, West Africa. We study three common Eurasian-African songbirds (Willow Warbler Phylloscopus trochilus, Melodious Warbler Hippolais polyglotta and Pied Flycatcher Ficedula hypoleuca) in a forested site, heavily disturbed by agricultural activities, and a forest reserve with no agriculture. The three species differed in non-breeding spatial strategies, with Willow Warblers having larger home ranges and being non-territorial. Home ranges (kernel density) of the three species were on average 1.5–4 times larger in the disturbed site than in the undisturbed site. Much of the birds’ tree species selection was explained by their preference for tall trees, but all species favoured trees of the genus Acacia. The overall larger home ranges in the disturbed site were presumably caused by the lower density of tall trees. Density of Pied Flycatchers was 24% lower in disturbed habitat (not significantly different from undisturbed) but Willow Warbler density in the disturbed habi- tat was more than 2.5 times the density in undisturbed. -

The Study of Bird Migration Across the Western Sahara; a Contribution with Sound Luring
The study of bird migration across the Western Sahara; a contribution with sound luring Marc Herremans Royal Museum for Central Africa, Leuvensesteenweg 17, 3080 Tervuren, Belgium; e-mail: [email protected] Report of field research in Mauritania during spring and autumn 2003 in association with the Sahara project of the Swiss Ornithological Institute (Vogelwarte Sempach). Abstract During spring and autumn migration 2003, the Swiss Ornithological Institute set up a concerted project in Mauritania to study bird migration across the Sahara (see www.vogelwarte.ch/sahara/). I participated with a side project using artificial induction of landfall with sound luring in an attempt to overcome the potential problem of low sample sizes for random trapping of natural landfall. A comparison with sound lured samples was also expected to provide more insights into the motivation of birds to stop or fly. In total, 9.467 migrants of 55 species were ringed, 590 birds recaptured locally and 49 ringed in Europe were recovered. Sound luring was more effective in autumn, when samples became, however, heavily dominated by Reed Warblers (Acrocephalus scirpaceus) and Garden Warblers (Sylvia borin). In autumn, adults migrated ahead of juveniles, and in Reed and Garden Warblers, most adults travelled over the interior of the Sahara, while juveniles were concentrated along the coast; no such effect was seen in species that avoided the interior (Nightingale Luscinia megarhynchos, Grasshopper Warbler Locustella naevia). Local recapture rates were low (6%), particularly inland in autumn (1%), where many more birds (12%) made longer stopovers in spring. In autumn, there were many more birds in poor condition along the coast than inland; birds in poor condition had much higher recapture rates, and birds in good condition (fat score >3, muscle score=3) rarely made a stopover. -

The Relationship Between Wing Area and Raggedness During Molt in the Willow Warbler and Other Passerines
J. Field Ornithol., 69(1):103-108 THE RELATIONSHIP BETWEEN WING AREA AND RAGGEDNESS DURING MOLT IN THE WILLOW WARBI.ER AND OTHER PASSERINES ANDERS HEDENSTROM Department of Animal Ecology Lund University,Ecology Building S-223 62 Lund, Sweden Abstract.--Molt involvesincreased metabolic cost due to the energy required to synthesize new feathers and increasedcost of thermoregulation becausethe insulation capacityis re- duced. Flight cost is also increasedbecause wing span and wing area are reduced when remigesare missingor growing. However,data on the reduction of wing area during molt (necessaryfor calculatingaerodynamic performance) is lacking.I showhow standardmolt scores(converted into a raggednessscore) can be used to estimate the reduction of wing area due to molt in Willow Warblers (Phylloscopustrochilus) and selectedother passerines. Maximum wing area reduction associatedwith maximum raggednessscore of the birds ex- amined wasapproximately 10%. Wing loadingwill thereforebecome increased during molt and flight performance will be reduced in similar waysas during migratory fattening.

Identification of Arabian Warbler
Identification of Arabian Warbler Hadoram Shirihai Illustrated by Alan Harris he Arabian Warbler Sylvia leucomelaena was originally placed in the Tgenus Parisoma. Meinertzhagen (1949), Williamson (1960) and others placed it in the genus Sylvia owing to its morphological similarities to this genus. Afik (1984) was convinced that this was incorrect, however, as its biological characteristics and nesting range differed from other Sylvia species. In the British Museum (Natural History), Tring, I compared the genera Parisoma and Sylvia. I believe that the Arabian Warbler represents a link between these two genera. Morphologically it resembles Parisoma in wing shape, tail-to-wing ratio, and tail pattern; the bill shape, however, is more similar to that of Orphean Warbler S. hortensis. The Arabian Warbler occurs on both sides of the Red Sea—in Arabia, Somalia and Sudan—between the genus Parisoma in Africa and the genus Sylvia in the Palearctic. In the 1960s, it was found to breed in the Arava Valley, Israel (Zahavi & Dudai 1974; Inbar 1977); this is the northernmost limit of its world range. The population in Israel is resident, making only short-distance movements. Three subspecies have been described: S. 1. blanfordi in Sudan, S. I. leucomelaena in Arabia and S. I. somaliensis in Somalia. A comparison between specimens from Israel and those in the British Museum shows the Israeli birds to differ both in plumage and, to a lesser extent, in size from these three races. They are most similar to the Arabian S. I. leucomelaena, but may be isolated from that race and thus may require recognition as a separate subspecies, S. -
