almost obliterated on tail; in all respects typical caroUncnsis as 

 described by Coues, Ridgway, and Baird, Brewer and Ridgway. 

 A specimen of the Sycamore Warbler (another Southern form) 

 was taken by Mr. Berry the same day — probably carried north by 

 the same migration wave. 



Family SYLVIID^. Warblers, Kinglets, and Gnat- 

 catchers. 



This family comprises the Old World true Warblers, the King- 

 lets, of which two species are found in Iowa, and the Gnatcatch- 

 ers, of which we have one species. They are active, restless little 

 birds, and are almost strictly insectivorous. They are quite mel- 

 odious songsters, although the Kinglets rarely sing before they 

 reach their summer homes, and the Gnatcatcher's notes are rather 

 weak . 



Subfamily REGULIN^E. Kinglets. 



Genus Regulus Cuvier. 



343. (748). Regulus satrapa Licht. Golden-crowned Kinglet. 

 The Golden-crowned Kinglet is a common migrant in all parts 



of the state, rather common as a winter visitant in southern Iowa, 

 and irregularly and rarely found in winter in northern Iowa. I 

 shot a specimen at Forest City (Winnebago), December 31, 1891, 

 and Dr. C. C. Smith has observed it in February and April in Win- 

 neshiek. The species usually arrives from the south about April 

 ist and is common until the 15th, (recorded March 24-May 7 in 

 Scott county), and in fall is most abundant in October (recorded 

 September ig-December i in Scott county). The Golden-crowned 

 Kinglets are generally seen flitting about the terminal branches 

 of low trees, frequently in willows along water-courses, but they 

 are also common in larger timber. 



344. (749). Reo;ulHs calendula (\S\\\\\.). Ruby-crowned Kinglet. 

 The Ruby-crowned Kinglet is an abundant migrant in all parts 



of the state, being in general more common than the Golden- 

 crowned Kinglet, the bulk arriving later in the spring and earlier 

 in the fall. B. H. Wilson has noted the species from April 4 to 

 May 20 and from September 18 to October 26 (Scott). The spe- 

 cies is not very often observed in winter, the only record being 

 that of Dr. Trostler, who reports it as an irregular winter visitant
