 Subfamily Falconinae. Falcons. 



FALCO MEXICANUS Schlegel. Prairie Falcon. 



Accidental visitant. 



The only record of the local occurrence of this falcon is the 

 specimen taken by Bryant in 1887. It may occasionally strag- 

 gle into the county during its migratory wanderings but there 

 is no further positive evidence of this. 



FALCO PEREGRINUS ANATUM Bonaparte. Duck Hawk. 



Uncommon migrant. 



-in 



This pirate among birds was a former summer resident in 

 this vicinity and is known to have nested along the river bluffs. 



It has not been often observed of late years, the only avail- 

 able dates being March 29, 1904, May 3, 1908 (specimen), Sep- 

 tember 18, 1914. 



FALCO COLUMBARIUS COLUMBARIUS Linn. Pigeon Hawk. 

 Uncommon migrant. 



There are but ten available authentic records of the local oc- 

 currence of this falcon; not enough to show the migration ex- 

 tremes. 



It may be looked for about timbered and open country dur- 

 ing April and October. It is of only casual occurrence and does 

 not winter here. 



[FALCO COLUMBARIUS RICHARDSONI Ridgway. Richardson's 



Pigeon Hawk.] 

 Probably a rare migrant. 



Though no specimens have been taken, this subspecies is no 

 doubt of local occurrence during migration as it has been re- 

 ported several times from surrounding territory. It is not 

 easily distinguishable in the field from the Pigeon Hawk and 

 specimens will have to be taken to establish its presence here. 



FALCO SPARVERIUS SPARVERIUS Linn. 



CERCHNEIS SPARVERIA SPARVERIA (Linn.). Proposed April 1917. 



Sparrow Hawk. 

 Very common resident. 



This is our commonest and most beautiful hawk and is found
