The main trend of the fall migration is southeastwards, mainly 

 west and south of Hudson Bay, but perhaps across it also, to the 

 Atlantic coast, mostly north of New En^^land. In favorable weather 

 the flight is over the ocean from Nova Scotia to South America over, 

 or to the eastward of, Bermuda, and the Lesser Antilles. Mr. Clark 

 (1905) figures out that this is the course they would take, if they 

 flew with a beam wind, across the prevailing winds. Of theii" course 

 after landing in British Guiana, he says : 



From this point their course is not accurately known ; but if we apply this 

 theory, they would follow down the northeastern tributaries of the Amazons 

 until they came within the influence of the southeast trades, which would carry 

 them southwest, over central Amazonia toward Peru and Boliva. Somewhat 

 northwest of the Matto Grosso region, the birds would come under the influence 

 of the easterly winds on the southern border of the trades, which would turn 

 them south, and gradually (as they became more northeasterly) southeast, 

 which would bring the plover into the prairie region of the Argentine. Here 

 the prevailing westerlies of the pampas region would be felt, and the birds 

 would, under their influence, continue down the eastern part of Patagonia 

 toward Tierra del Fuego. 



To add strength to his theory he says that there are specimens 

 in the British Museum from Mount Roraima and the Maroni River, 

 Surinam, and from Peru taken in September and October. 



Some birds on the fall migration wander as far north and east as 

 Baffin Island and northeastern Labrador. Lucien M. Turner refers 

 in his notes to several adults which he saw and two which he col- 

 lected, near the mouth of the Koksoak River, between July 24 and 

 August 19, 1882; and I have a specimen in my collection taken near 

 Hopedale, Labrador, a young bird. Hantzsch found this plover 

 breeding on Baffin Island. 



Edwin Beaupre (1917) writes: 



In September, 1906, a great flight of plover passed over the city of Kingston, 

 which is located on the extreme eastern end of Lake Ontario. The flight Avas 

 first noticed about 8 o'clock in the evening, and to one familiar with the soft, 

 sweet piping of the golden plover, there was no difiiculty whatever in recogniz- 

 ing the bird. A record of the flight showed that eight flocks passed over the city, 

 flying very low, at intervals of about 10 minutes. Toward midnight it was 

 impossible to enumerate the flocks, the flight being continuous. This must 

 have been the main migration for that year, and it continued until 4 o'clock 

 in the morning, covering eight hours. Allowing a speed of 25 miles an hour — a 

 conservative estimate — the distance between the leading flocks and the rear 

 guard must have been approximately 200 miles. What a sublime spectacle 

 this would have been had one the privilege of seeing it in the open light of day ! 

 The vanguard of this great aerial aggregation must have reached almost to 

 the Atlantic seaboard, while the rear flocks were trailing their wonderful 

 way over the eastern waters of Lake Ontario. They no doubt began their 

 ocean journey some miles south of the coast of Nova Scotia, but not far enough 

 to seriously affect their regular route to Argentina, in which country they 

 escape the hardship of a Canadian winter.
