The authorities consulted in reference to the irruption of 

 1888 are numerous notes in the Naturalist, the Zoologist, 

 and the Field for 1888 and 1889. 



Subsequent to the 1888 invasion of this species, the 

 following occurrences are reported : 



On 24th May 1890 six were seen, coming in from the 

 eastward, by two boatmen while about half a mile at sea 

 off the Spurn light ; the birds passed within thirty yards, 

 and were afterwards seen to alight on the sandhills (Nat. 

 1890, p. 202). In May 1891, the late Col. Haworth-Booth 

 saw six on the cliff tops at Roulston ; a pair procured soon 

 afterwards was in his possession (op. cit. 1895, p. 327). On 

 I3th May 1899, a small flight at Easington was seen by Mr. 

 P. Loten (op. cit. 1899, p. 175), and the latest occurrence is 

 reported to me by Mr. T. Wellburn, keeper, of Millington, 

 East Yorks., who writes that, in the second week of February 

 1904, he observed a flock of eighteen, travelling northward ; 

 they passed him within a few yards, and, having seen many 

 in 1888, when he had five specimens through his hands, he 

 easily recognised them by their flight, long pointed wings 

 and tail feathers, and also by their call note. A neighbouring 

 keeper saw a small flock about the same time.
