BJRD VISION 17 



tailed tits visited me one winter. They had no 

 idea of being afraid of anything on the other side 

 of the window : possibly they could not see me. 

 I think the smaller birds have great difficulty in 

 seeing through a window. I could put my head 

 quite close to them without frightening them. 

 But they noticed the fear of the other birds, and 

 after some time some weeks followed their 

 example and flew away too. 



The robin seems to see further into a room 

 than any other bird (it sees me as I sit by the fire) , 

 but with that exception the rule seems to be that 

 the larger the bird the larger its head, that is - 

 the more easily it sees me through the window. 

 The cole tit seems to see further than the blue tit ; 

 but then, though its body is smaller, its head and 

 eye are, I think, rather larger. The blue tit does not 

 see far, and it usually refuses to be alarmed until it 

 really does see for itself the cause of the sudden 

 flight of the other birds. A very funny thing it is 

 to see a blue tit stand on end, as it were, and peer 

 over into the room on tiptoe, drawn out to its 

 thinnest and longest, and then, either not seeing me 

 or thinking that I am not dangerous, settle down 

 comfortably into a little round ball in the midst of 

 the crumbs, only too glad to get them all to itself. 

 Very greedy and very courageous is the blue tit ; 

 plebeian and ungraceful in manner, but of all birds
