Question: Of the birds recorded during November, which species lays the largest eggs? Passage 1:Ice hockey, referred to as simply "hockey", is Canada's most prevalent winter sport, its most popular spectator sport, and its most successful sport in international competition. Lacrosse, a sport with Indigenous origins, is Canada's oldest sport. Canadian football is Canada's second most popular spectator sport, being the most popular in the prairie provinces. The Canadian Football League's annual championship, the Grey Cup, is one of the country's largest annual sports events. While other sports have a larger spectator base, Association football, known in Canada as soccer in both English and French, has the most registered players of any team sport in Canada. Professional teams exist in many cities in Canada. Statistics Canada reports that the top ten sports that Canadians participate in are golf, ice hockey, swimming, soccer, basketball, baseball, volleyball, skiing (downhill and alpine), cycling and tennis.
 Passage 2:This extended training period meant that he had accumulated 138 flying hours in his pilot's logbook before he finally joined No. 66 Squadron RFC in Italy on 10 March 1918. He was assigned to "C" Flight, flying a Sopwith Camel single seat fighter, and became the preferred wingman of fellow Canadian ace Billy Barker. Birks' first aerial victory came on 18 March, when he destroyed a Rumpler reconnaissance aircraft over Pravisdomini, killing an Austro-Hungarian pilot named Shneeberger. Six days later, he set another reconnaissance aircraft on fire, killing the crew of Poelzi and Suski. His third victory would not come until 2 May, when he wounded Leutnant K. Kosiuski and drove him into a crash landing that destroyed his Albatros D.V. Two days later, Birks shot down and killed ace Oberleutnant Karl Patzelt, as well as F. Frisch. In addition to killing both Austro-Hungarian pilots, he destroyed both their Albatros D.Vs; they were credited as "captured" because they fell within Italian lines. The new ace shot down another D.V in flames a week later, on 11 May. He destroyed two Berg fighters in five minutes on a morning patrol on 19 May. The following day, he destroyed another. On 24 May, while flying with Barker, Birks was credited with shooting down Hungarian ace József Kiss of Flik 55J; Birks thus became a double ace. On 9 June Birks set another Albatros D.V on fire in mid-air. On the 21st, he capped his list of triumphs by destroying another D.V over Motta. Most unusually for a British pilot, he had no "soft" victories, such as "driven down out of control".
 Passage 3:The wintering migrant birds which flock to the sanctuary were recorded at different periods during the winter months. The early arrivals in October were gadwall (Aythya ferina), northern pintail (Anas acuta), northern shoveller (Anas clypeata), common teal (Anas crecca), common pochard (Aythya ferina), and common coot (Fulica atra). The birds recorded during November were mallard (Anas platyrhynchos), spot-billed duck (Anas poecilorhyncha), and knob-billed duck (Sarkidiornis melanotos). The departure of the birds from the sanctuary was also noted in different months, towards the end of the winter season. The summer birds recorded were the lesser whistling duck (Dendrocygna javanica) and the cotton teal (Nettapus coromandelianus).
