THE GREAT WAXWING INVASION OF 1 92 1 201 



flocks of finches, etc., for at least several days at Christmas 

 time — four or five were shot, but I did not examine crops in 

 these days, and it's no more than an idea that I have now, 

 that they must have been feeding, like their companions, on 

 refuse corn, etc." 



While this is no doubt true of a minority of the birds, 

 the evidence of the 192 1 immigration seems to indicate that, 

 as food became scarce, the majority moved onwards and 

 ultimately southwards. 



Regarding the mode of feeding, Mr Douglas Hunter 

 writes : " I watched for a long time another solitary bird 

 in a garden in the western suburbs of Arbroath. It was 

 feeding upon some rose-hips and showed no signs of fear. 

 I noticed that it swallowed the small hips whole. The large 

 ones it took in right into its beak, and caused them to 

 revolve, peeling them as they did so. Only the seeds were 

 eaten, the rind falling to the ground. Sometimes the bird 

 fed on the ground, sitting in the snow."

No man has had better opportunities for studying the mental 

 capacity of animals in confinement than the Director of the magnificent 

 New York Zoological Park ; but animals in confinement often behave in 

 'different fashion from their wild fellows, and the author has wisely 

 broadened his observation by many excursions to the haunts of wild 

 creatures in different parts of the world. The greater part of his 

 volume consists in recording outstanding instances of intelligence and 

 reasoning power as shown in the natural habits or acquired ways of a 

 large number of animals, for he sets great store, as a test of intelligence, 

 on the ability of an animal to undergo training by man. Here the 

 interesting fact is brought to light that, as with man, animals of the 

 same species may vary to an extraordinary degree in brain capacity. 



On the whole, however, the Chimpanzee must be regarded as the
