“…This claim was based on a clear SW heading of a group of adults of that species in orientation tests performed at Burullus in the Nile Delta. The same was reported for a few individuals of different species tested at the Bahariya Oasis by Stêpniewski et al (2011). These were 9 of 59 individuals tested: three Yellow Wagtails, Motacilla flava, two Willow Warblers, Phylloscopus trochilus, two Rufous Bush Robins, Cercotrichas galactotes, one Garden Warbler, Sylvia borin, and one Collared Flycatcher, Ficedula albicollis.…”

The general migration pattern of passerines can be estimated using a variety of methods. A number of partial analyses based on ringing data, usually limited to a few species, have been published. A very few continent-scale presentations have been offered, as extremely long periods of ringing activity are necessary for passerines. This is especially true for areas where the recovery rate is very low, including vast areas of north-eastern and eastern Europe and the Middle East/Africa. Similarly, radar and moon-watching studies are of limited value for drawing migration patterns within wider areas. Radar studies require good coverage by the radar systems, while weather radar distribution density and the level of evaluation are very uneven. Modern logger and satellite tracking are more applicable to non-passerines, and as yet enable detailed study only of limited numbers of individuals, and not population studies. At the end of the 20th century, a very simple tool was introduced for field studies on the preferred headings of individual birds caught for ringing, i.e. the use of flat orientation cages. This method was introduced as a standard within the SEEN (SE European Bird Migration Network) in 1995. This study presents a preliminary large-scale evaluation of the data collected within this project. The database used contains more than 43,000 orientation tests performed at 45 ringing sites. The area covered stretches from the northern part of western Russia to southern Egypt and from Italy and Poland to Siberia and Armenia. Eight streams of migration are identified within this area, creating a fairly complicated pattern of avian movements.

“…One need to remember that the reverse headings (in northern sectors of the wind rose in autumn) shown in the graph have the same information value as the southern sector directions (e.g. Formella and Busse 2002, Zehtindjiev et al 2003, Stêpniewski et al 2011.…”

A new research project near Jericho in the Jordan Valley (Palestine) was launched on 10 September 2013, work continued until October 23rd 2013. Standard ornithological work and bird ringing work was conducted using mist nets situated in an oasis type habitat of Wadi Qelt surrounded by palm plantations. The field methods followed the SEEN (SE European Bird Migration Network) standards that include apart from ringing of captured birds, also several measurements (wing length, tail length, wing formula) and scores (fat load and body mass), as well as the studies on the directional preferences of migrants using round, flat orientation cages. Ornithological research was enhanced by parasitological studies analysing migratory birds (hosts) - helminths relations during migration period of the former. This was a part of complex studies covering the Middle East and north African ringing sites. Altogether 481 individuals of birds representing 59 species were ringed and about 50 were retrapped. The most interesting was relatively high share of Masked and Red-backed shrikes as well as good number of birds of local species as Dead Sea Sparrows and introduced Indian Silverbills.

Work begun in autumn 2013 at a research ringing site near Jericho in the Jordan Valley (Palestine) was continued in spring 2014 (8 March–18 April). Due to a flood, the area was much changed in relation to the autumn habitat distribution. Standard ornithological and ringing work was performed using mist nets. The methods used were in accordance with SEEN (SE European Bird Migration Network) standards, and apart from ringing included some measurements (wing length, tail length, wing formula) and scores (fat determination and body mass), as well as testing of the directional preferences of migrants. The ornithological work was expanded to include parasitological testing, taking into account migrant-helminth relations during migration. Altogether 508 birds from 44 species were ringed and inspected for external signs of infection by Collyriclum faba trematodes (subcutaneous cysts), and an additional 32 dead individuals were collected and dissected. Altogether 168 internal parasites were found. The most common migrants in spring were Lesser Whitethroat Sylvia curruca, Blackcap Sylvia atricapilla and Olivaceous Warbler Hippolais pallida, while the autumn dominants–Masked and Red-backed shrikes (Lanius nubicus and L. collurio) were scarce. In spring a good number of Dead Sea Sparrows Passer moabiticus were caught, but only two introduced Indian Silverbills Lonchura malabarica.
