#Empidonax minimus# (Baird and Baird), Least Flycatcher Oberholser (_op. cit._, 397) listed this species as an uncommon transient since he had only a few sight records at hand. Since field identification of all eastern empidonaces in fall is open to question, our recent data, based on collected material, are significant. Six specimens have been taken at University on dates ranging from September 15 to October 5, and five at Cameron between July 25 and October 17 inclusive (Lowery, _et al._). Another specimen in the collection is that of a bird taken by Burleigh at New Orleans on October 1, 1942. There is, as yet, no unquestionable spring record for Louisiana. #Pyrocephalus rubinus mexicanus# Sclater, Vermilion Flycatcher Oberholser (_op. cit._, 401) listed only one record for this species, a male observed by H. E. Wallace at University, on February 6, 1938, and shot the next day by me. Since 1938, however, it has been found regularly and frequently at numerous localities in southern Louisiana in winter. At Baton Rouge, for example, an adult male was noted almost daily between October 19, 1941, and January 7, 1942, at a small pond on the University campus. An immature male was seen there also on November 25, 1941, but not thereafter. In the following autumn another adult male appeared at the same place on October 23, and was observed regularly until January 15, 1943. Again, an adult male returned to the same area on November 10, 1943, and remained until the middle of January, 1944. W. C. Abbott informs me that for several years one or two individuals have spent the winter at a small willow-bordered pond at his home near Hopevilla, Iberville Parish. Like the individuals noted at Baton Rouge, Abbott's birds arrived in October or November and remained until the following January or February. H. B. Chase, Jr., noted two individuals at City Park Lake in New Orleans in the winter of 1944-45, and three at the same place in the winter of 1945-46. I have seen the species frequently in Cameron Parish, in southwestern Louisiana, where six specimens have been collected on dates ranging from November 4 to January 22. Atwood (Auk, 60, 1943: 453) has also recorded its presence near the Laccasine Refuge in Cameron Parish. An immature male was obtained at False River, near Lakeland, in Pointe Coupee Parish, on November 8, 1942 (Burdick). E. A. McIlhenny writes me that he has seen the species many times at Avery Island and recently he sent me a skin of an adult female which he collected there on October 25, 1945 (also _cf._ McIlhenny, Auk, 52, 1935: 187). From these data it is evident that the Vermilion Flycatcher is now a regular winter visitor to southern Louisiana. #Troglodytes troglodytes pullus# (Burleigh), Southern Winter Wren
