260 Natural History of the 



An Osprey was afterwards seen on several occasions, when 

 ascending the Rouge, wheeling about high in the air, and a large 

 nest probably of this bird, was seen on a dead pine on the shore 

 of Trembling Lake. The numerous lakes full of large trout must 

 afford this species abundance of food. 



3. Falco sparverius, Linn. (American Sparrow Hawk). — One 

 of this pretty species was observed by me at Sixteen Island Lake. 

 When camped on Hamilton's Farm on the Rouge in August, 

 they were very numerous, generally pitching on the burnt pine- 

 trees round the clearing. They were mostly birds of the season. 

 The stomach of an old male I shot on the 28th August, was filled 

 with Grasshoppers, Black Field-Crickets and Coleoptera, all broken 

 up into small fragments. The last seen by me was on the 7th 

 October. 



4. Astur palumbarius, Linn. (Goshawk). — Several of this large 

 hawk were observed round the clearings of Hamilton's Farm, at 

 the end of August and beginning of September. 



5. A. fuscus, Gmel. (Sharp-shinned Hawk). — One specimen 

 was seen near Gate Lake in the 6th Range of Wentworth, May 

 16th ; none were observed again till we reached the large farm 

 where the two last species occurred. This was also very numerous 

 there at the end of August, delighting to pitch on the dead pines 

 which thickly stud some parts of the clearings. 



6. Circus cyaneus, Linn. (Marsh Harrier). — An immature bird 

 of this species was frequently seen at the end of August and in 

 September, about the clearing just mentioned, which being 

 the only one for 25 miles on either side, offers great attractions 

 for most of the hawks which delight in open places, their usual 

 prey generally inhabiting such situations. 



7. Syrnium nebulosum, Linn. (Barred Owl). — On the 5th Sep- 

 tember I observed one of this Owl in the woods not far from 

 Trembling Lake, in the township of Grandison. 



8. Otus brachyotus, Linn. (Short-eared Owl). — I saw a speci- 

 men which had just been shot on the 9th October near the house 

 on Hamilton's Farm. I was informed that this species is not 

 uncommon there in the fields after harvest. 



9. Bubo Virginianus, Gmel. (Great Horned Owl). — Numerous 

 throughout the district and frequently seen. 



10. Chordciles Virginianus, Briss. (Night Hawk). — A single 

 individual was observed by me flying about after dusk on the 21st 

 and 26th August, at Hamilton's Farm.
