buildings on February 29th. As migrants arrived on March 10th 

 I think it survived. My first seen dates range from the date given 

 to April 11th. The dove usually nests in groves about farm houses, 

 but I once found a nest on the ground in a clover field. From the 

 latter part of July until the doves depart on their fall migration 

 in late October they select common roosting places, one of which 

 happens to be our orchard. Toward sunset the doves visit some 

 place to drink and then fly to the roosting place from all direc- 

 tions until between five and six hundred are roosting there. They 

 depart again just as it becomes light in the morning, spending the 

 day far away in pastures and grain fields. During the month of 

 August they may be commonly found about salt troughs for cat- 

 tle, seeming to eat the salt. In late October the numbers coming 

 to the roost gradually become fewer, until none come in on whist- 

 ling wings at sunset. 



Turkey Vulture (Cathartes aura sevtentrionalis) . Mr. Lee re- 

 ported that vultures used to be very common. The last nest he 

 saw was in 1875, and the last bird about 1910. Mrs. E. B. Hayden 

 said that vultures or buzzards were common along the Coon river. 

 Mr. Joe Abernathy reported two seen near Sac City in the spring 

 of 1915. 



Swallow-tailed Kite (Elanoides forficatus) . A specimen taken in 

 Ida county, which adjoins Sac on the west, is in the Smith collec- 

 tion. Mr. Lee reported the swallow-tail kite as rare, with the last 

 one seen in 1908. Mr. Tiberghien also reported it as rare. 



Marsh Hawk (Circus Jmdsonius). Specimen in the Smith collec- 

 tion. This species is a tolerably common breeder in suitable 

 sloughs. I know of three sloughs within a few miles of Wall lake, 

 where it breeds regularly. It does not nest in the " Goosepond," 

 probably owing to the fluctuating water level. I think it occasion- 

 ally winters, as I have seen it on Christmas day and early in Feb- 

 ruary. First dates of arrival, other than February, are from March 

 29th to April 20th. 



Sharp-shinned Hawk (Accipiter velox). Specimen in the Smith 

 collection. A rare spring and fall migrant, with more observed in 

 the spring than in the fall. I know of no breeding records, al- 

 though they may nest in the timber along the Coon river. 



Cooper Hawk {Accipiter cooperi). A rare spring and fall mi- 

 grant. I have seen about five individuals all told. It may nest in 

 the timber along the Coon river. 



Red-tailed Hawk (Buteo borealis lorealis). A rare spring mi- 

 grant in the vicinity of Wall lake, but some years a common fall 

 migrant in the month of October. My first seen dates in spring are 

 March 3rd and 6th. I have no record of its nesting. 



Western Red-tailed Hawk {Buteo borealis caJurus). A rare fall
