Salientian Breeding Dates in Oklahoma 



ARTHUR N. BRAGG 



DURINCt approximately thirteen years, records of the breeding activ- 

 ity among the SaHentia each year about Norman, Cleveland County, 

 have been kept and other data of the same sort from other regions 

 of the state have been recorded at every opportunity. These have now accu- 

 mulated to such an extent for several species that an analysis can be made of 

 the range in the breeding periods characteristically used, and these can be 

 related to the breeding patterns as outlined earlier (Bragg, 1944-45, 1946). 



Of the twenty-eight forms known in Oklahoma, seventeen have been 

 observed more than ten times. These are recorded in Table I. In the construc- 

 tion of this table the numbers of breeding congresses observed are given by 

 half months, January through September. No records occur during October 

 through December. In handling the dates, days 1-15 were considered the first 

 half month, 16-30 or 31, the second half month. Years were disregarded as of 

 no consequence to the purpose of the table. Table II gives the observed sea- 

 sonal range for these same species. All are records of clear-cut breeding con- 

 gresses in Oklahoma except a very few observed just over state lines in ad-
