Essentiall}' a coa.st bird, the Laughing Gull is probably only 

 an irregular or casual visitor to the Mississippi Valley. Accord- 

 ing to Professor Cooke a few pass up the Mississippi duiing the 

 summer as far as southern Illinois, while it was recorded by 

 Mr. Powell at Alden, Nebraska, in July, 1880. May not, how- 

 ever, Franklin's Gull (Z. fi-ankllnii) have been mistaken for it?
