AND OTHER BIRDS 41

 at any rate there never seemed to be in the sky 

 at one period, more than a few score. 



The vast numbers we had been led to expect 

 were disappointingly absent. The influx, too, 

 of such birds as did appear varied in numbers 

 from night to night. Each evening, too, the 

 hours of arrival differed, on one occasion none 

 arriving until half -past eight. 



Our experience of the spring and early sum-

 easily credible what I afterwards heard, that 

 the birding season of 1912 was the worst ever

The paucity of occupied burrows may have, 

 in part, accounted for our inability to discover 

 a sitting bird, or the deplorable weather may

 entire breed. We failed, at any rate, to obtain

 selected partners. 



The Kuaka came in from the ocean later than 

 during October, and not as before in such vast 

 numbers for so brief a period of time. In all
