male Purple Marriii, which was the earliest record for this species that I have 

 ever made and not withstaiidiiifi- that the weather turned very cold and there 

 came two snow storms after that, he remained ritjht alon^ ; March 29, White- 

 rnmped Shrike ; March :30, Fox Sparrow ; April 1, Field, Vesper and Chipping- 

 Spilrrows ; April 19, Whippoorwill ; April 32, Brownthrasher ; April 28, Scarlet 

 Tana^er. I give the above as a sample of the species that appt ared at aboiit the 

 usual time and became common in the usual time after arrival. This is only a 

 partial list of such species, but enough to illustrate the point. The following 

 species came straggling along : Towhee, first seen Apr. 6, which is very late 

 for this species ; did not become tolerably common until Apr. 14 and was not 

 present in its usiial numbers before the last of the mouth. Cowbird. first seen 

 Apr. S, about an average date, but they did not become fairly common until the 

 IfSth and wa; not T)resent in the usual numbers before the 24th inst. Red-eyed 

 Viero, first seen Apr. 28, straggled along until May 12 before it was fairly com- 

 mon, and is not present in its usual numbers yet, June 19. Golden Warbler, 

 first Apr. 28, tolerably common May 7 ; this species usually comes nearly in a 

 bulk. Black and White Warbler, first seen May 1 ; no more iintilMay 14, never 

 appeared common. Orchard Oriole, first Apr. 29, a single bird; was not com- 

 mon before May 10. Baltimore Oriole, one bird seen Apr. 28, no more for 

 several days ; did not arrive in tlie usual number imtil May ] 2 ; this species 

 usually arrives nearly in a bulk. Dickcissel, first, a single bird May 5, next a 

 single bird May 9, became common about a week later. Cliestniit-sided Warbler 

 was not seen until May 6, a late date, and was only fairly common three days 

 later, and the bulk of the species did not appear for some time after. Tennessee 

 Warbler did not make its appearance until May 10, a very late date for this 

 species, ])ut they all came at once and were present for ten days. Yillow Throat 

 was not seen until May 15, the latest date for the species I have ever recorded, 

 a7id then they did not become common before the 2()th. Yellow-billed Ciickeo, 

 was not seen before May 11, when a single bird was seen, biit no more until 

 May 20, and only a very few has been seen this season. Wood Pewee, first seen 

 May If), about ten days later than the average; they were common three days 

 later. Ruby-tliroated Hummingbird, first seen May 12, not much behind the 

 average, but with the exception of a few stragglers, the species was not present 

 until two weeks later when they became common. Heretofore I have always 

 found this species common at the time of the flowering of the wild Columbine, 

 bat this year the Oolumlnnes were m full bloom when the first arrived. Bell's 

 Vireo, one was seen May 10 and another May 14 which is all of this species that 

 I liave seen the present season. Heretofore this has always been a common 

 l)reeder here. Yellow-breasted Chat, first seen May 9 and a few mere May Hi. 

 Tliis bird also has failed to locate in tlieir usual haunts and up to the present 

 time [ have failed to find a single pair nesting, nor have I heard a bird for some 

 time. Kentuclcy Warbler has nested liere during the past few seasons, but this 

 year none have been seen or heard. This being about the northern limit of this 

 species, doubth^ssly it has not advanced this far the pr(>sent season. I tliink 

 the foregoing examples, although but a few, will serve to sh(n\' that the season 

 just past luid an uniisual ett'ect upon the movements of some species.
