The species was not met with again until we reached the Taku 

 River. At this point during September, marsh hawks were seen 

 daity hunting over the meadows bordering the river. These 

 meadows were thickly populated with meadow-mice (Microtus 

 (Irionniondi), which seemed easy prey, for I frequently saw 

 the hawks drop down in the grass, to arise at once grasping a 

 mouse. The stomach of one of the birds secured contained several 

 meadow-mice (Microtus) and one jumping mouse (Zapus). 

 They resented the appearance of any other birds of prey upon 

 their hunting grounds, and I repeatedly saw them attack bald 

 eagles, as well as a short-eared owl and a rough-legged hawk. 

 Two marsh hawks were preserved, both males in first winter 

 plumage (nos. 9772, 9773). 



Accipiter velox (Wilson). Sharp-shinned Hawk. 



Seen at various points during the spring and summer, 

 though rare everywhere. On Kupreanof Island, on April 23, 

 Hasselborg found a nest, finished but empty, with one of the old 

 birds near by. On Kuiu Island a sharp-shinned hawk was seen 

 pursuing some sandpipers. Single birds were observed at the 

 following points: Prince of Wales Island (Calder Baj'), Coro- 

 nation Island, Heceta Island, Dall Island, Duke Island, Chick- 

 amin River, Revillagigedo Island (Portage Cove), ]\Iitkof 

 Island. At Thomas Bay during the latter part of August they 

 became fairly common, as the immature birds began to appear, 

 moving southward. Several were seen at Port Snettisham, and 

 on the Taku River the species was quite abundant. 



They were frequently observed in pursuit of small birds, 

 and several of those secured had the remains of sparrows or 

 juncos in their stomachs, but one (no. 9776) had eaten two 

 shrews. 



Six specimens were secured, as follows : adult male, ^litkof 

 Island (no. 9774), adult female, Taku River (no. 9778), imma- 

 ture female. Port Snettisham (no. 9776), immature male, Thomas 

 Bay (no. 9775), and an immature male and female, Taku River 

 (nos. 9777, 9779). The two adults are extremely dark colored, 

 as compared with summer specimens from California, Nevada 

 and Illinois. The male bird (no. 9774, Mitkof Island, August
