counting the occasional visitants. It is also sur- 

 prising to find that two of the Argentine owls are 

 well-known British species the Barn Owl and the 

 wide-ranging Short-eared OwL Of the six species 

 I was acquainted with five, and will describe the 

 two I knew most intimately, the Short-eared and

 occasionally saw in Buenos Ayres city, but always at

 Patagonia* 



The Short-eared Owl is found throughout the 

 Argentine country, where it is commonly called 

 Lechuzon (Big Owl) in the vernacular. Like the 

 Barn-Owl it has an exceedingly wide range. It is

 inhabits Asia and Africa, many of the Pacific Islands, 

 and both Americas, from Canada down to the Straits 

 of Magellan, Such a very wide distribution would

 than most Owls, and differs structurally from other 

 members of its order in having a much smaller head,

 I am sure is a great mistake, for it seems to me to be 

 the strongest flier amongst Owls, and very migratory 

 in its habits, or, at any rate, very much given to 

 wandering. Probably its very extensive distribution 

 is due in some measure to a greater adaptability than
