Zimmer, John T. Instinctive Feeding Habits of Young Herons. 

 (Ibid., p. 94.) — Young herons invariably speared fish placed in a pan of 

 water on the first thrust and as invariably missed those placed on the floor. 

 The refraction of light passing through the water is suggested as the reason, 

 the birds being accustomed to take their food from shallow water aim their 

 thrusts accordingly. 



Oberholser, H. C. Aristonetta a Good Genus. (Ibid., p. 98.) — In 

 the opinion of the author this name should be revived for the Canvasback.

 the North American Tree Sparrow. (Ibid., p. 98.) Fringilla canadensis 

 Bodd. has been cited as an earlier name for this bird but it proves to be 

 based on the young of some other species, possibly the White-throated 

 Sparrow.
