with similar habits recorded for little blue herons and egrets in the 

 East. 



An American coot, one of 18 marked on August 20, 1016. was shot 

 on December 5 about 75 miles south, near Lehi, Utah. As this species 

 is not hunted extensively in the West, nothing was heard from others. 



Though 10-4 young white-faced glossy ibises were banded in rook- 

 eries where they nested in company with snowy herons, return has 

 come from but 1 individual. This bird, marked July 3, 1916, and 

 found sick on the shores of Tulare Lake, Calif., on October 22, 1922, 

 indicates a migration movement from the Salt Lake Valley toward 

 the southwest. 



The snowy heron nests in colonies in the lower Bear River marshes, 

 and on July 3 and 1-1, 1916, 83 nestlings were marked with bands. In 

 March, 1917, a peon at Mexcaltitan, Territory of Tepic, Mexico, 

 brought a bit of aluminum to a Japanese labor contractor, saj'ing 

 that he had found it on the leg of a heron that he had killed and 

 eaten. The band had been preserved out of curiosity, as the peon 

 was unable to read, but chance had brought a return on one of the 

 snowy herons that was marked in L^tah the previous year. About 

 June 1, 1917, another snowy heron killed on the Papagaj^o Lagoon, 

 in Guerrero, Mexico (long. 99° 48' W., lat. 16° 48^ N.), was re- 

 ported through the State Department by the American consul at 

 Acapulco. A third record is of a snowy heron found on the San 

 Pedro Eiver, in northwestern Cochise County, Ariz., on April 13, 

 1919; and a fourth is furnished by a heron recovered at Escuinapa, 

 Sinaloa, Mexico, on January 20, 1923. 



These dates indicate that the breeding snowy herons of the Salt 

 Lake Valley winter on the west coast of Mexico. Their route north- 

 ward may follow the Colorado River, or birds may scatter in an in- 

 land flight that carries them more or less directly northward. In 

 Utah it was observed that though part of the snowy herons arrived 

 early, others continued to join the breeding colonies until late in 

 June, observations that coincide with the late date at which one from 

 this region was secured in Guerrero.
