HABITS OF THE HERRING GULL—-STRONG. 509 
17. It is a common practice of these birds to rinse in water food 
of uncerta‘n palatableness or when it is dirty. 
18. Some evidence was obtained concerning the use of nerves of 
general sensation in testing food. 
19. A positive reaction is shown to air currents. In a severe 
storm gulls leave the ground and indulge in flight maneuvers. 
20. The herring gull is sensitive to extremes in temperature. In 
very cold weather the feet are kept protected by the plumage a large 
portion of the time. 
21. There is a large amount of bathing, especially in hot weather. 
In very cold weather no water seems to be required beyond that 
present in the food obtained.
