122 THE SCOTTISH NATURALIST 



The Northern Chiffchaff, Phylloscopus collybita abietinus. 

 A Chiffchaff recorded from Noss Head on 22 nd August probably 

 belonged to this sub-species. 



The Willow-warbler, Phylloscopus trochilus trochilus. The 

 early records come from Melrose on i8th April, Kilmacolm on 19th, 

 Corsemalzie next day, Summerston on the 21st, Killermont on the 

 22nd, Darvel on the 23rd, and Little Ross and Isle of May on 24th 

 April. After this arrivals are reported from all over Scotland up to 

 25th May, the chief influx taking place between 30th April and 8th 

 'May. 



Return movement is reported from the Isle of May on 7th 

 August, and from that time till mid-September there are a good 

 many notes of southward movement, evidently referring chiefly to 

 the departure of our home-bred birds. A Willow-warbler at Noss 

 Head on 27th August was probably a passage migrant from the 

 Continent. Last seen Balgay on 14th September, Largo on 17th, 

 Cullen on 19th, and Corsemalzie and Broughty Ferry on 20th 

 September. 



The Wood-warbler, Phylloscopus sibilatrix sibilatrix. Arrivals 

 are recorded from Tarholm near Ayr on 2nd IMay, Darvel and Corse- 

 malzie on 7th, and Cullen on 17th May. Single birds are noted at 

 Balgay (Forfar) on 28th July and 18th August. 



The Grasshopper-warbler, Locustella ncevia n<zvia. Is re- 

 ported from Beith on nth May, Kilmacolm on 17th, Fossil Marsh 

 on 20th, and near Mount Stuart (Bute) on 22nd May. 



The Sedge-warbler, Acrocephalus schmwbcenus. Very early 

 records of this species come from Summerston on 22nd, 24th, and 

 25th April, the only previous instance of such early arrival in Clyde 

 being in 1893. Sedge- warblers are reported at Corsemalzie on 6th 

 May, Beith on 8th, Darvel on loth, Kilmacolm and Invergowrie 

 on 1 2th May, and arrivals at breeding sites are noted up to 29th 

 May. 



By 24th July return movement had begun, and many notes come 

 from our southern stations, evidently of the departure of our breeding 

 birds, up to the end of August. Last seen Broughty Ferry on 30th 

 August, Fossil Marsh "over thirty on passage" on 8th September, 

 and Corsemalzie, three on the moors, on nth September. 



The Garden-warbler, Sylvia boriti. The records of arrival 

 are rather late in 1918. On 7th May a Garden-warbler visited the 

 Isle of May, and records come from Tarholm (Ayr) next day, Darvel 

 on the 9th, Melrose on 13th, Beith and Rouken Glen on the 14th
