“…These syndromes rely on a suite of phenotypic traits that co-evolve to determine the behavioural types of individuals. Such syndromes have been extensively studied in the context of migration because migration implies selection on morphological characters for long distance movements (Van Noordwijk et al, 2006) resulting in different characteristics between migrant and resident individuals (Sandberg and Moore, 1996;Lõhmus et al, 2003;Marchetti and Zehtindjiev, 2009). For example, Leisler and Winkler showed that migrant birds are generally smaller and have shorter tails and longer wings than non-migrant individuals (Leisler and Winkler, 2003).…”

SUMMARYFlight direction is a major component of an animal's migratory success. However, few studies have focused on variation in flight direction both between and within individuals, which is likely to be correlated with other traits implied in migration processes. We report patterns of intra-and inter-individual variation in flight direction in the large white butterfly Pieris brassicae. The presence of inter-individual variation in flight direction for individuals tested in the same conditions suggests that this trait is inherited in P. brassicae and we propose that a rapid loss of migratory skills may exist in the absence of selection for migration. The magnitude of intra-individual variation was negatively correlated to two surrogates of the potential for migration: mobility and wing length. Highly mobile and longed-winged individuals within the same family were found to fly in similar directions, whereas less mobile and short-winged individuals displayed divergent flight direction compared with the average direction of their kin. There was also a negative correlation between the variance to the mean flight direction of a family and its average mobility, but no correlation with wing length. We discuss these issues in terms of the evolution of traits potentially implied in both migration and dispersal in P. brassicae.

“…Although they have been rarely studied in this respect, migratory birds do show personality traits (Battley 2006, Marchetti andZehtindjiev 2009). Because there is still very little known about the ecological consequences of personality traits in the context of migration, our prediction is derived from the numerous studies conducted in other contexts (see above).…”

“…By comparing the variation in body mass between different ecological sectors, they were able to show when and where migrants accumulated their migratory fuel reserves during migration. Marchetti and Zehtindjiev (2009) studied the migratory orientation of Sedge Warblers (Acrocephalus schoenobaenus) in relation to feeding and exploratory behaviour. They performed the orientation tests with Emlen funnels, which showed much variation, partially due to birds' personalities.…”

This is an overview of ornithological studies carried out in Egypt since the beginning of XX JD century till the present time made on the basis of several more or less general publications. Geographical location and climate descriptions give the background information about the area. The literature overview stresses especially problems connected with the migration of passerines, but wider avifaunistic background is discussed as well. Special attention is paid to the passerines' strategy of migration through the Mediterranean Sea and Sahara Desert, its direction and timing, as well as to the factors affecting passerines migration and bird ringing in Egypt. In conclusion, it is stressed that the studies on bird migration were done sporadically, from time to time and from one place to another, and there is a dramatic lack of permanent ringing / bird migration study field stations, despite the fact that some suitable and promising localities have been found, in which the studies have been carried out since 2001 by the SE European Bird Migration Network in cooperation with some protected areas managements.
