From the foregoing- notes the following conclusions are 

 suggested relative to the two species of Vulture in this 

 vicinity. 



Catliarista iirubu occurs in greater numbers. 



It is found more frequently associated and is more varia- 

 ble in occurrence. 



It flies more direct to a feeding place and usually drops 

 the feet and legs sometime before alighting. 



It is the less numerous species close to the gulf shore. 



Cathartes aura septentrionalis not as numerous in the 

 springtime as in the fall and winter. 



The two species do not usually associate intimately while 

 feeding. 



Both species may be attracted from long distances when 

 food continues to be abundant; 142 Black Vultures and 163 

 Turkey Vultures were counted on one and the same day. 



During a term of three years there were 75 days when no 

 Black Vultures were seen and but 21 days when no Turkey 

 Vultures were observed, and for the same period during 25 

 months the daily maximum reached or exceeded twenty in 

 the case of C. uruhu, and for but six months with C. a. sep- 

 tentrionalis. 



Extremes of variation in the enumeration show 375 Black 

 Vultures and 86 Turkey Vultures counted during March, 

 1917, and in August, 1916, the numbers were 61 Black Vul- 

 tures and 62 Turkey Vultures.
