This bird may be looked for during the period between the 

 first of April and November. It is included in our list, because 

 of a specimen which was shot from the government pier at 

 Chicago in April, 1903. In September, 1892, I obtained several 

 specimens from a flock of between 700 and 1,000 of these birds 

 at Meredosia, Illinois. Mr. Bowers, of the United States Fish 

 Commission, and myself approached within 150 yards of the 

 flock and it was comparatively easy to count them. In June, 

 1895, Mr. Blackwelder and myself obtained a fine pair from a 

 flock of fourteen at Meredosia. Mr. Nelson says: "At present 

 ( 1876) an exceedingly rare visitant during the migrations. For- 

 merly they were regular and rather common migrants." 



The White Pelican frequents temperate North America, being 

 quite abundant in the interior and along the Gulf coast. While 

 its known nesting localities are at least as far north as the state 

 of Minnesota, there are indications that it also breeds along the 

 Gulf coast from Florida to Texas.
