Plover there. The neighboring marshes on the east side may 

 be the determining factor or the presence of the ponds that, 

 on the east side, wash the inner line of the shore dune in some 

 places, and are not separated from the beach by a belt of timber 

 as on the west. There are many indications, however, that 

 the preference is largely governed by the migrational routes 

 taken by these migrants in approaching and leaving the Point. 

 Just such a condition of affairs would be exhibited if the 

 waders on the fall migration approached the Point from the 

 east side and so along that shore and leaving at the extremity ; 

 reversing the route in spring. Such seems to be the course of 

 the Sharp-shinned Hawk flight and what data we have of the 

 distribution of waders on the north shore of Lake Erie seems 

 to substantiate the theory. Gulls and Tern show a less pro- 

 nounced preference for the same shore but perching birds, as 

 would be expected, are almost absent from it except at such 

 times as described by the residents during the latter part of 

 May, 1907, when, after prolonged interruption of migrations 

 by unseasonable weather, the sparsely sprinkled Cottonwoods 

 scattered along the eastern shore were alive with tanagers and 

 warblers. At other times we have found but such typical 

 species as Savanna Sparrow, Prairie Horned Larks, Palm 

 Warblers and a few White-crowned Sparrows, and late in the 

 'season, Snowflakes and Pipits. Practically the same con- 

 ditions prevailed during all our visits. 



The most interesting feature of the Point ornithological ly, 

 however, is the intrusion of Carolinian forms of life. This is 

 backed up and supported by the botany as noted by Mr. A. 

 B. Klugh, who says : 



'The floral aspect of Pelee is decidedly Carolinian as is 

 shown by the occurrence of the following plants : Sand Grass, 

 Triodia purpurea, Summer Grape, Vitis aestivalis, Wiry 

 Panic-grass, Panicum phUadelphicum, Swamp Rose-mallow, 

 Hibiscus moscheutos, Florida Milkweed, Accrates longifolia, 

 Button-wood, Platanus occidentalis, Black Walnut, Juglans 

 nigra, White-heart Hickory, Carya tomcntosa, Sassifras, 

 Sassifras officinalis, and Chestnut Oak, Q'uercus prinus." 



How far these conditions, peculiar for Canada, prevail in-
