Oenanthe hispanica (6.0). The three highest infestation rates (Table 8) 
for birds of which more than 50 were handled were Phoeri'Lcuvus phoenicurus 
(17.0), Anthus tvividlis (10.0), and Sylvia communis (6.0); other high 
rates of infestation were found in Passer domesticus (70.0), Falco 
tinnunoulus (30.0), Oenanthe oenanthe (18.0), and Falco navmanni (15.0).

In Egypt, in the spring of 1969 (Table 5), infested birds compris¬ 
ing 25 species yielded 271 ticks representing 5 species: Eyalorma 
marginatum'^'rufipes^ Amhlyorma variegatim^ A, nuttalli^ Ixodes euplecti^ 
and Argas (PersiOargas streptopelia. All bird species but 2 yielded 
Eyalomma marginatum rufipes. of these Anthus trivialis and Oenanthe 
oenanthe yielded two other species of ticks and Eippolais icterina 
and Luscinia megarhynchos each yielded one other species. The 34 high¬ 
est infestation loads were on Streptopelia turtur (5.3), Oenanthe 
oenanthe (4.2), Phylloscopus sihilatrix (3.5), and Carduelis chloris 
(3.0). The 3 highest infestation rates (Table 8) for birds of which 
more than 50 were handled were: Oenanthe oenanthe (14.0), Luscinia 
megarhynchos (12.0) and Oenanthe hispanica (8.0). Another high in¬ 
festation rate was found on Oenanthe isahellina (5.0). 
In Egypt, in the spring of 1970 (Table 6), 508 infested birds 
comprising 34 species yielded 1124 ticks representing 9 species: 
Eyalomma rn, rufipes^ Amhlyorma variegatum^ A. nuttalli^ A, lepidum^ 
Ripicephalus turanicus^ Ixodes euplecti^ J. arhoricola^ I. sp. nov, and 
Argas (Persiargas) streptopelia. All bird species but 2 yielded 
Eyalomma marginatum rufipes. Of these Anthus trivialis yielded 4 other 
species, Luscinia megarhynchos^ 2 other species, and Eirundo rustica 
and Jynx torquilla one other species each. The 4 highest infestation 
loads were on: Streptopelio. turtur (12.0), Turdus philomelos (7.0),
