Abstract
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.
