38 Wood, Winter Birds in Wayne Co., Mich. [f^^^ 



part of each Sunday to field work during the two months under 

 consideration. The territory selected was a part of P. C. 120 and 

 321, City of Detroit, and P. C. 69G, Grosse Pointe Park; all being 

 in what was formerly the village of Fairview. The following refers 

 to the above locality unless otherwise specified. A star (*) indicates 

 positive identification. Messrs. Walter C. Wood, Bradshaw H. 

 Swales and Jeft'erson Butler very kindly furnished me with what 

 data they possessed and I take this opportunity to assure them of 

 my sincere appreciation. Mr. Swales's observations were made on 

 Grosse Isle, Monguagon Township. 



1. Circus hudsonius. Marsh Hawk. — A junior female appeared 

 December 13 and was last seen January 10. Two primary feathers of the 

 left wing were missing which enabled me to identify all seen on the various 

 dates as the one bird. Mr. W. C. Wood saw a female on Section 29, City 

 of Wyandotte, January 27. 



2. Accipiter cooperi. Cooper's Hawk. — A junior female was seen 

 January 1 and 3 ; probably the same bird both days. 



3. Buteo borealis. Red-tailed Hawk. — Mr. Swales writes: "During 

 December from one to three frequented the northerly part of the island 

 and were seen every time I went back to the woods. They were what 

 remained from the large numbers that passed through in October and 

 November." 



4. Buteo lineatus. Red-shouldered Hawk. — A junior male appeared 

 December 13 and was last seen January 10. December 20 it dropped into 

 a flock of Tree Sparrows but missed its intended victim. 



•5. Archibuteo lagopus sancti-johannis. American Rough-legged 

 Hawk. — December 16 a bird, in rather dark plumage, lit in a willow in 

 front of Mr. Swale's residence and was observed at close range. 



6. Haliaeetus leucocephalus. Bald Eagle. — Mr. Swales saw a junior 

 bird December 11 flying over the Detroit River. 



7. Falco sparverius. American Sparrow Hawk. — A male appeared 

 December 13 and was last seen January 3. Another male flew down the 

 main street of River Rouge Village, January 13, passing within ten yards of 



throughout the year, usually keeping well out in the lake. Redheads, however, 

 occasionally breed; the general belief being that an uninjured bird remains with a 

 cripple, but it seems more probable that many recover their power of flight and no 

 longer care to migrate. Four pairs of Redheads and two pairs of Lesser Scaups 

 nested near Mr. Krauss's lT,otel in 1908. This may be considered unusual when 

 compared with the Flats as a whole, and looks like enforced residence, but the facts 

 in this respect will remain unknown and imparts an uncertainty that destroys their 

 scientific value, in my opinion; and an equally confusing tendency is realized when we 

 attempt to fix the dates of arrival and departure by individual bird records and will 

 remain so until duck shooting is prohibited. These conditions also apply, in a 

 measure, to certain species along the water front of Wayne County.
