mon. There are only a few summer records and none for 

 winter. 



ACCIPITER COOPERI (Bonaparte). Cooper's Hawk. 



Common migrant and summer resident; occasional winter resident. 



This harmful species arrives during the first few days in 

 March and is present until late October. There is but one win- 

 ter record (January 20, 1917) and no specimens have been 

 taken during midwinter, though Bush says that it is present 

 throughout the entire year. 



The nest is found in timbered places, usually in a fork about 

 thirty feet high, and a full clutch is four or five eggs. Four 

 sets in the Tindall oological collection, two of four and two of 

 five eggs, were taken near Independence between the 1st and 

 29th of May. 



This hawk may be looked for about the Swope Park region 

 and in the country west of Dodson, as well as in the timbered 

 bottoms of the Missouri River country. 



ASTUR ATRICAPILLUS ATRICAPILLUS (Wilson). Goshawk. 

 Very rare and irregular winter visitant. 



At infrequent intervals this northern hawk is known to in- 

 vade this part of the country during the late fall and winter. 

 The winter of 1916-1917 witnessed such an invasion. Over 

 fifty specimens were sent in to the University Museum at Law- 

 rence during the winter, most of which had been taken in the 

 neighborhood. One was killed near Dodson and another seen 

 on December 5, 1916. 



Three specimens in the Dankers collection were taken Feb- 

 ruary 17, 1902, November 2, 1906, and December 1, 1906, re- 

 spectively. 



Goshawks may be looked for here only during the most se- 

 vere winters. 



BUTEO BOREALIS BOREALis (Gmelin). Red-tailed Hawk. 

 Common resident. 



Red-tailed Hawks are present in numbers throughout the 

 winter; they become more numerous late in February and the 

 bulk of the migrants are here around the 12th of March. By 

 the last week in March the local birds are nesting. Sixteen 

 sets of eggs collected by Tindall of from one to three eggs each
