In the usual fashion, the failure with the Common Kingfisher 

 has been very great. The other Kingfishers, in proportion to 

 their size, show poor maximum and average durations, and these 

 birds must be regarded as of relatively low viability. Although 

 there are no cseca, the hind-gut is relatively long and capacious. 

 Mr. Gurney cites, from the Rotterdam Gardens, an instance of a 

 Laughing Kingfisher having lived for 11 years. Our highest 

 regard is 7 years. In the period in question these birds have 

 been kept in the Western Aviary, with heated interior but access 

 to open air.
