74. Sykes*s Warbler. Hypolais rama (Sykes). 



Not mentioned by Shelley. 



Of rare occurrence in autumn. 



Like the above but slightly browner above and with a 

 smaller bill, a longer first and a shorter second primary. 



75. Icterine Warbler. Hypolais icterina (Vieillot). 



Phyllopneuste hippolais. Shelley, p. 103. 

 Occurs during the autumn migration and probably also in 



spring. 



Length 5 inches. Upper parts olivaceous brown washed 

 with grey; under parts pale lemon yellow; bill broad at base. 

 Sexes similar. 



76. Reed Warbler. Acrocephalus streperus (Vieillot). 



Calamoherjie arundinacea. Shelley, p. 94. 



Common on passage in spring and autumn. A few remain 

 throughout the winter. 



Length about 5| inches. Upper parts rufous brown; under 

 parts sulphur and rufous buff. The female is very slightly 

 smaller than the male. 



77. Marsh Warbler. Acrocephalus palustris (Bechstein). 



Calamoherpe palustris. Shelley, p. 91. 



Not uncommon during both migrations. 



Differs from the reed warbler in being less rufous. The 

 arrangement of the flight feathers is also different, but these 

 points are difficult, if not impossible, to detect unless the bird 

 is in the hand. The legs and feet are yellow and not lead colour 

 as in the reed warbler. 



When on the wing it appears less rufous and yellower than 

 the reed warbler, young birds of the year appearing to be almost 

 sulphur coloured. 



78. Great Reed Warbler. Acrocephalus arundinaceus (Linnaeus). 



Acrocephalus turdoides. Shelley, p. 96. 



A few pass through during both migrations. 



Nearly allied to the following species, but bill stouter and 

 plumage less hair-like. The female is very slightly smaller than 

 the male.
