A survey of the bird-parasitizing louse flies (Omithomyini) in Israel was canied out between 1990 and 1993. Specimens belonging to 13 species were examined. Seven species were previously known from Israel (lcosta ardeae (Macquart), I. meda (Maa), I. minor (Bigot), Ornithoica turdi Olivier, Ornithomya chloropus (Bergroth), Ornithophila metallica (Schiner), and Pseudolynchia canariensis (Macquart)), and six species are recorded as new to the Israeli fauna (Crataerina pallida Olivier, from swifts (Apus apus); Icosta zumpti Maa, from a buzzard (Buteo buteo); Ornithomya avicularia L., from a blackbird (Turdus merula) Ornithomya biloba Dufour, from swallows (Hirundo rustica) and sand martins (Riparia riparia) Ornithomya gigantea n. sp. (described here), from a blackcap (Sylvia atricapilla); and Ornithophila gestroi Rondani, from lesser kestrels (Falco naumanni)). Louse flies were found on 26 species of birds, 24 of which constitute new host records for Israel.

that breeding failure and mate loss (divorce or death) favored breeding dispersion, both in males and females of Black Kites ( Milvus migrans ).

The day-to-day variation in the quantity of prey eaten depends upon the average number of prey eaten (the law of large numbers).

pairs are raising fewer young, and residents leave areas at higher rates if the number and quality of other pairs’ nestlings there are low (Doligez et al., 2002 ). Lesser kestrels ( Falco naumanni ) use the reproductive success of other breeders to select breeding sites over successive breeding seasons
