VOL. xm.] THE BIRDS OF BARDSEY ISLAND. 73 



to be described. On these days the passage lasted from 

 early morning to lo or ii a.m. On the i6th, 17th and i8th 

 the movement was of far greater intensity, especially on the 

 16th and 17th, when it was practically continuous, in small 

 parties from early morning to noon. On all three days White 

 Wagtails predominated. On the i6th, and to a lesser extent 

 on the 17th, two distinct routes were being pursued at once. 

 We found that the two best observing places for these birds 

 were the west bay, where there is a small area of dry sand, 

 frequently used by them as a halting and feeding place, and 

 the southern tip of the island, where a point could be found 

 commanding a view of the tip, the sea on each side, a good 

 view to the north and a long stretch of both east and west 

 coasts, and here, as also on the roofs of the lighthouse buildings 

 near by, the birds often halted also. The main Wagtail route 

 passed from north to south along the west coast. The birds 

 arrived either from the north (or the north-west, it is not 

 quite certain which) and could be seen when at the west bay 

 coming down low over the rocks from the north and passing 

 on with or without halting, either down the coast, or down the 

 centre of the island, to its southern tip, where they flew straight 

 out to sea directly south. Nearly all the small parties on the 

 other days followed this route, and only once did we see a 

 party flying across the cultivated area and they were going 

 in the same direction. 



The" other route, which we came to recognize as the Pipit 

 route, was only seen used by Wagtails at the southern tip 

 of the island. Here the birds came in, flying low over the 

 sea from the south-west (one party came in from the west on 

 the i6th) and after crossing the tip of the island, with or 

 without halting, they continued in the same direction which 

 took them directly up the east coast towards the southern 

 shoulder of the mountain, where they were lost to view. It 

 is probable, however, that from this point they followed 

 the same route taken by the Meadow- Pipits (17.7.'.), which 

 would bring them to the Welsh coast in the neighbourhood 

 of Hell's Mouth. 



The British Goldcrest {Regulus r. anglorum). 



Probably a regular double-passage migrant, but at present 

 there are only two spring records, viz. : April I4th/i5th 

 and 20th'2ist, 1912, of small numbers on each night. 

 Autumn passage from second week in September to the first 

 week in November. Occasionally in early December. Numbers 

 always small.
