76. Elanoides forficatus (Linn.) Swallow-tailed Kite. Mr. 
Webster tells me that this species was at one time tolerably 
common, but could furnish no further data. John R. Waller 
says that he has occasionally shot specimens. There is a single 
specimen, probably taken in the county, in the Miles collection. 
Considerably to my surprise C. H. Belanski and I identified 
a specimen of this bird at Hackberry Grove, in Cerro Gordo 
County, on May 28, 1916. 
77. Circus hudsonicus (Linn.) Marsh Hawk. The Marsh 
Hawk is a common summer resident in Floyd and adjoining 
counties. The relative abundance seems to vary rather 
markedly from year to year. Spring arrival in late March of 
early April, and departure takes place in late October and 
early November. Due to the habits of the species it is less 
noticed, and therefore less persecuted than others of the - 
hawks. 
78. Accipiter velox (Wils.) Sharp-shinned Hawk. A com- 
mon migrant and a less common summer resident. On May 
4, 1917, I located a nest of this species, with two eggs in 
Waller’s Woods, northeast of Charles City. In July of the 
following year young birds were observed in this same wood- 
land. 
79. Acctpiter cooperi (Bonap.) .~Cooper’s Hawk. This 
species is a common summer resident. Prior to 1916 I found 
no nests with eggs or young, but in 1916, 1917, 1918, and 1919 
occupied nests were located in various parts of the county 
and near Hackberry Grove. 
80. Accipiter atricapillus atricapillus (Wils.) Goshawk. 
A rather rare migrant and perhaps winter resident. Four 
individuals were seen in the northern part of Charles City 
on November 11, 1917, and there were several reports of the 
species in the third week of April, 1918. It is probable that 
all of these records applied to the same birds. I saw two in-’ 
dividuals on April 16. 
81. Buteo borealis borealis (Gmel. Red-tailed Hawk. A 
tolerably common summer resident, arriving in mid-March. 
Nests with eggs have been found in the second week of May,
