nolia, Chestnut-sided, and Blaekburnian Warblers, and the Wilson's 

 Thrush. About a week later, a much heavier 'wave' follows, 

 bringing the first Olive-baeked Thrushes, many Catbirds, Black- 

 throated Green and Tennessee Warblers, and transient Indigo 

 Buntings in large numbers. The Kingbird is not often seen after 

 this period of migration. Apparently the only winter visitor to 

 arrive with this 'wave' is the House Wren. But while the passage 

 of transients continues unabated for several weeks yet, the coming 

 of a considerable number of winter visitors is not delayed much 

 longer. Savanna and Swamp Sparrows and the Phoebe arrive 

 very early in October, if not before. White-throated Sparrows, 

 Myrtle Warblers, Winter Wrens, and both Ruby-crowned and 

 Golden-crowned Kinglets should be expected at New Orleans 

 almost if not quite by October 15. The presence of these species, 

 however, may not be obvious until the occurrence of considerably 

 fresher weather about October 20. The American Pipit arrives 

 within a few days later. The Red-eyed Vireo and Wood Thrush 

 are now seen for the last time. Of transient warblers, the Black- 

 and-white, the Bay-breasted, the Blaekburnian, and the Chestnut- 

 sided, are seldom seen later than October 15, while the Worm-eating 

 and Yellow Warblers always depart by that date. But important 

 waves of the Black-throated Green Warblers may occur after 

 October 20, while the Parula, Tennessee, Magnolia, and Hooded 

 Warblers, and the Redstart remain until November 1 or later, 

 which is also the time of departure of the Yellow-billed Cuckoo, 

 Nighthawk, Chimney Swift, Ruby-throated Hummingbird, and 

 Wood Pewee. 



After the last transients have left there are but few winter visitors 

 to arrive. The Robin, however, is a species of which little is seen 

 until about the middle of November, and Rusty Blackbirds scarce- 

 ly arrive earlier than that. The Goldfinch, however, has generally 

 come to southern Louisiana by November 15, and the Orange- 

 crowned Warbler by November 20. W T ith White-throated Spar- 

 rows arrived in their full numbers, and with the first decidedly 

 cold weather commonly occurring about this date, the status of 

 winter bird life is practically complete, though Robins, Black- 

 birds, and occasionally a few other species show continued increase 

 until after Christmas.
