Notes on the Subaqueous Habits of the Water Ouzel, 



** During the years 1849 and 1850, having nearly daily occasion to frequent 

 that pari of the river Dodder which passes through the romantic mountain glens of 

 Glenismael and Castlekelly, the great abundance there of the water ouzel, or, as the 

 peasantry there call it, kingfisher, induced me to study its habits somewhat particularly. 

 I have repeatedly seen them rise to the surface to obtain air, which they do exactly 

 like a grebe, merely raising the tip of the bill out of the water. The bird has several 

 modes of diving. When seeking food it generally goes down, like most divers, head 

 foremost, in an oblique direction, or else walks deliberately in from the shallow edge 

 of the pool, the head bent down and the knees (tarsal articulation) crouched. When 

 seeking refuge, however, it sometimes sinks like a stone, exactly as the great northern 

 diver {Colymbus glacialis) has been observed to do, — that is, gradually, without any 

 apparent exertion, sometimes in the midst of its most rapid flight dropping down 

 suddenly into the water like a plummet. Its course is indifferently with or across the 

 stream, rarely against it. It often remains under water totally submerged fur fifty 

 seconds and upwards, and during that time will proceed from 10 to 20 yards : when it 

 comes out the water may be seen running rapidly ofl' its plumage. It swims with 

 great rapidity, and appears to rejoice in the water, as its true element, hardly ever 

 alighting directly on a rock, but even after its longest flight splashing slap into the 

 water, at the base of the stone selected as a resting-place, and then scrambling to the 

 summit of this. In its motions in the water it more closely resembles the jackass 

 penguin than any other aciuatic bird I have had an opportunity of studying: like that
