Louisiana Lowery (1974) noted less than two dozen "positive" identifica- 

 tions of Whistling Swans in Louisiana, and commented that these swans are rarer 

 than in the past. There was an influx in the winter of 1976-77; nine individ- 

 uals were reported at five localities (Hamilton 1977). Records extend from 

 15 November through mid-February (Lowery 1974). 



Texas Oberholser (1974) listed Whistling Swans as locally scarce to rare 

 in Texas, occurring between September and April; extremes are August and 3 May, 

 and there is a summer record for Dallas County. Prior to 1900, swans apparent- 

 ly were common throughout the state. They are now locally scarce to rare both 

 inland and along the coast (Oberholser 1974). Recent records are as follows:
