8 THE ZOOLOGIST. 



Corn-Crakes excepted. None of the species appeared in large 

 numbers. 



Following the order of season, regardless of the particular 

 year, I now record the observation made by Mr. Glanville 

 (Principal Lightkeeper). On Sept. 12th, 1911 (the same day of 

 the month that the last-mentioned Eobin appeared in 1912), he 

 saw a Eobin on the Eock at 7.40 a.m., in company with a Wren, 

 a Goldcrest, a Whinchat, some Wheatears, and Sedge-Warblers. 

 It was the second day of my first visit to the Eock, and, being 

 inexperienced, I thought it would be probably an easy matter to 

 secure these specimens if I hunted them up later on. But I 

 found out my mistake, for, on coming out two hours later when 

 I had finished writing my journal notes, the Eobin, the Wren, 

 and the Goldcrest were nowhere to be seen. I have since 

 learned that birds may in some instances alight on the Eock for 

 a few minutes, and it is a good rule to go out and look for them 

 the moment one hears of their presence. The Sedge-Warblers 

 and Wheatears, however, remained on, and I collected specimens 

 of each. Later in the day I saw a Pied Wagtail, and in the 

 evening collected a specimen of the Blue-headed Wagtail* and 

 of the Spotted Flycatcher. On this occasion the Eobin was 

 migrating in company with several species. All these birds no 

 doubt tarried to seek shelter on the rock, for the morning set in 

 very wet, and the wind, at first blowing a moderate breeze, rose 

 later in the day to a fresh, and still later to a strong, breeze. 

 The sky also remained very overcast and gloomy-looking, and 

 rain fell all day long. 



Two days later — here again according to season and not 

 to year, i.e. on Sept. 14th, 1912 — 1 observed a Eobin on the 

 Eock at 9.30 a.m. It was tame, rather fatigued, and easily 

 collected. This morning Meadow-Pipits and Swallows flew past 

 the Eock ; several Pipits alighted, also two Grey Wagtails and a 

 Pied Wagtail. In addition three other Grey Wagtails passed 

 over the Eock. The morning was fine, bright, and fairly 

 calm, the wind an hour before noon falling off to a flat calm. 

 The prevalent wind during the day was west. On the night of 

 the same date, at 8.2 o'clock, I saw a bird whose plump build 

 and quiet flight, as it drew near the lantern, suggested tome that
