74 IOWA ACADEMY OF SCIENCE Vol. XXV, 1918 



while up the Big Sioux valley, came across a Groshawk which 

 had been sliot a few days before by the farmer because it had 

 been killing chickens. The following specimens were sent to 

 Mr. Anderson for mounting: 



No. 3010. A beautiful male from Wynot, Nebraska, Febni 

 ary 7, 1918. 



A spoiled specimen from Laurel, Nebraska, ]\Iarch 22, 1918. 

 No. 3094. A female from Page, Nebraska, March 27, 1918. • 



11. Red-tailed Hawk. Buteo horeaJis. This species was 

 seen during the months of September, October, December, Jan- 

 uary, and February; and it has been seen during the winter 

 months in other years. 



12. Harlan's Hawk. Buteo harlani. On March 29, 1918, 

 Mr. A. J. Anderson collected a male hawk of this species, which 

 is probably simply a melanistic phase of Buteo horealis. This 

 specimen was taken between Salix and Sergeant BlufiP, and is 

 now in Mr. Anderson's collection. 



13. Rough-legged Hawk. Archihuteo lagopns sancti-johan- 

 nis. This species is very easily identified while in flight because 

 of the dark band across the belly, and the dark patch covering 

 the under primary coverts of each wing; these marks are con- 

 spicuous at a considerable distance. Four field records and four 

 specimens were obtained, as follows: On October 28, 1917, one 

 individual was seen flying over Crystal Lake, Nebraska, by A. F. 

 Allen and myself; on November 4 another was noted near Stone 

 Park by Mr. Allen ; and on November 5 two were seen at Bad- 

 ger Lake by Messrs. Anderson, Ludcke and Stephens. The fol- 

 lowing specimens were received by Mr. Anderson for mounting: 

 on October 30, 1917, a male and a female from Sheldon, Iowa; on 

 November 29 a male which had been shot in Bacon Hollow, Sioux 

 City ; and on December 1 a female which had been sent in from 

 Ute, Iowa. Mr. Anderson has mounted only seven other spec- 

 imens of this species since 1900. 



14. Ferruginous Rough-legged Hawk. Archihuteo ferrugi- 

 neus. Mr. Anderson mounted one on September 17, 1917, which 

 had been shot at Brown's Lake (Woodbury county), Iowa. He 

 also mounted another one on October 11, 1917, which had been 

 sent to him from Warsaw, Nebraska.
