WATCHING GULLS AND SKUAS 105 



the case, for they laid down what they pulled in 

 different places, and several times they attacked each 

 other and fought quite fiercely. With other birds, too, 

 I have noticed a kind of rivalry between the females 

 when collecting materials for the nest. Hen chaf- 

 finches seem particularly jealous of each other in this 

 respect. They pull the lichens from the trunks of 

 trees, fluttering up against them, and using both their 

 claws and beaks, and when thus engaged, or when

 who would fain be tender are annoyed and hampered 

 by a rejected suitor the villain of the piece. This

 the next occasion, which is immediately afterwards. 

 This goes on for some time, the envious bird becoming 

 more and more rancorous and more and more torn 

 between rage and discretion every time valour assaults 

 him. At last rage carries it, and, strange to say, 

 considering it as melodrama he, the villain, makes
