grant in southeastern Dakota, but it is known to breed in Kansas, Mis- 
souri (Goss), and Texas. Mr. Nehrling states that it is resident, but 
not common, near Houston, in eastern Texas. It has been found in cen- 
tral Iowa, and even as far east as Illinois. 
356. Falco peregrinus anatum (Bonap.). [414.] Duck Hawk; Peregrine Falcon. 
This species occurs locally throughout the Mississippi Valley. It 
breeds more particularly in Manitoba and the northern half of the 
United States, but is known to breed also in Kansas, Mississippi, and 
Texas. In the fall of 1884 the last Duck Hawk was seen at Mount 
Carmel, Mo., November 12. 
In the spring of 1885 it was seen April 4 at Lake City, Minn., and 
April 25 at Mount Carmel, Mo. 
357. Falco columbarius Linn. [417.] Pigeon Hawk. 
Occurs over the whole of the Mississipi Valley, but is nowhere abun- 
dant; winters in the Southern States and southward; breeds in Brit- 
ish America. A few stragglers were found at San Angelo, Tex., in the 
winter of 1883-84, the last of which left February 1, being the first bird 
to migrate. Near Houston, in eastern Texas, it is common in fall and 
winter (Nehrling). At Heron Lake, Minn., the first was noted March 
27; and none were seen at Manhattan, Kans., until April 12. In the 
spring of 1885 the Pigeon Hawk was recorded from Ferry, Iowa, March 
30; Clinton, Wis., March 31; Delavan, Wis., April 11; and Ossowo, 
Manitoba, April 18. In the fall of 1885 the first at Emporia, Kans., 
was noted October 10. 
358. Falco richardsonii Ridgw. [418.] Richardson’s Merlin. 
Found principally on the Great Plains, and thence westward, but is 
most common just east of the Rocky mountains; south to Texas in 
winter; has occurred accidently in Michigan, and occasionally in Minne- 
sota. Professor Aughey recorded it as rather common, and breeding, in 
Nebraska. Dr. Agersborg saysitis a migrant in southeastern Dakota. 
Mr. Powell reports it from southeastern Nebraska. It probably breeds 
in western Kansas, where Colonel Goss saysit isnot uncommon. At 
Ellis, Kans., Dr. Watson noted the arrival of the first April 15, 1884. 
An accidental visitor has been recorded from Laporte City, lowa. 
359. Falco fusco-ccerulescens Vieill. [419.] Aplomado Falcon.

Rio Grande in Texas (Merrill). 
360. Falco sparverius Linn. [420.] Sparrow Hawk. 
Inhabits the whole of Manitoba and the Mississippi Valley, and breeds 
throughout its range; but in Indian Territory and eastern Texas it is 
apparently rare and local asa breeder. In Tom Green and Concho 
counties, Tex., it is an abundant resident (Lloyd), but the summer 
birds pass south in winter and their places are taken by northern birds,
