THE BIRDS OF FLOYD COUNTY, IOWA. 255 
are doing moderately well, but are killed to such an extent 
that their number cannot increase. 
Several pairs of the Hungarian Partridge, Perdix perdix, 
were placed in the same preserve, but seem to have died out. 
230. Passer domesticus (Linn.) House or English Spar- 
row. The most abundant bird of the region, particularly 
about towns. It is less common in the country, particularly 
in the open fields and woodlands. 
HYPOTHETICAL LIST. 
On this list are placed species that I do not feel justified 
in including in the first part of this section. Mr Gabrielson 
is of the opinion that the Brant (List No. 32) should be placed 
here, but I hardly agree on this point. 
1. Florida caerulea caerulea (Linn.) Little Blue Heron. 
I have several times seen birds that I identified as belonging 
to this species, but do not regard the identification as unques- 
tionable. My most reliable record was secured north of 
Charles City, June 12, 1917. 
2. Dryobates villosus villosus (Linn.) Northern Hairy 
Woodpecker. Mr. Brown and I have various sight records for 
this species, and Mrs. Tuttle reports it from Osage. Positive 
identifications are lacking. 
3. Sturnus vulgaris (Linn.) Starling. Mr. Brown and 
I have at various times seen ‘birds which we felt certain of 
as Starlings, but secured no specimens. The most reliable of 
my dates are: April 25, 1914; July 24, 1914; May 3, 1915. 
Mr Gabrielson considers these records as positive errors, 
Dr. Bailey accepted them as hypothetical, and Miss Sherman 
accepts them. In a letter to me she expressed the opinion 
that the species had been introduced into the Mississippi 
Valley from the east. She mentioned a record for Rockford, 
Illinois, by Mr. Paul B. Riis. 
4. Nuttalornis borealis (Swains.) Olive-sided Flycatcher. 
There is little doubt that this species is found in Floyd County, 
but pending the solution of our Flycatcher problem, it is 
listed here. 
5. Kmpidonax flaviventris Baird. Yellow-bellied Fly-
