Discusalon 
From these data it would appear that waterfowl abundance in New Tork at 
the end of the 1949 breeding season waa, in general, about double that of 1948. 
Cf the four principal especies, the mallard showed the greatest, and the wood 
duck the least, degree of increase, The black duck continues to be by far the 
most important hreeding species in this State. 
In conaidering the figures, it should be noted that they were recordad 
by the seme pilot and ohserver, using the asme technique, and following the 
eame flight route during both years.
