in migration were not as evident in 1969 as in 1968, but there appeared to 
be a broad peak between the last week in March and the middle of April, 
Numbers of Sytv'ia atvicccpitla and Sylvia ourvuoa were much higher in 1968 
than 1969, but Passer modbiticus was much more common in 1969. 
Some conspicuous differences show up when the Israel migration data 
are compared in gross fashion with the Egyptian data. Some species that 
are common on one route are rare or absent on the others while for other 
species there are significant seasonal differences in abundance. A 
few of these apparent differences may merely be due to differences in 
methods of capture or differences in local habitat at the capture site. 
Among these are probably the falcons, quail, and doves which were cap¬ 
tured in numbers in Egypt but were rare in the Israel samples. These 
species require special methods of capture and are favored by the 
Bedouins. The ground'dwelling Motaoilla flava and possibly Anthus 
oervinus^ on the other hand, probably avoided the Bedouin’s tree nets 
in Egypt but were captured easily in mistnets in Israel. 
Species that were common in Egypt at one or both seasons but were 
markedly less common or rare in Israel were: Cuoulus canorus^ Upupa 
epops^ Calandretla oinerea^ Lanius collurio^ Lanius minov^ Hippolais 
ioterina^ Sylvia oormunisj S. rueppelli^ S. cantillans^ Phylloscopus 
sibilatrix^ Fioedula alhioollis^ F. hypoleuoa^ Musoioapa striata^ 
Fhoeniourus phoeniouruSy Turdus merula^ T. philomelos^ Passer domestious 
(resident)^ and Oriolus oriolus. 
Species that were common in Israel at one or both seasons?but were
