 Sialia macroptera Baird 



in Stansbury, Exploration and survey of the valley of the Great Salt 

 Lake of Utah, Appendix C, Birds, p. 314, 1852. 

 =Sialia currucoides (Bechstein). See Hellmayr, Catalogue of birds of 



the Americas 7: 482, 1934. 

 3706. Adult male. Salt Lake City, Salt Lake County, Utah. Mar. 18 

 {fide original description) or 21 {fide the oldest label, written by Baird) , 

 1850. Collected by Howard Stansbury. Exploration and Survey of 

 the Great Salt Lake of Utah (1849-1850) . 

 The oldest label carried by this skin, with data in Baird's hand, gives the 

 collection date as Mar. 21, "1851," but in the original description it was 

 stated to be Mar. 18, 1850. Since Stansbury 's party was no longer in the 

 field in 1851, it is obvious that the date on the label is, at least in part, 

 erroneous.
