Naturally occurring infections of Plasmodium relictum and H aemoproteus sacharovi in pigeons of Central Iowa have recently been reported (Becker, Hollander and Pattillo, 1956). In that survey, involving pigeons of all ages, both microscopic examination of stained blood films and isodiagnosis were employed, but the examination of blood films stained in Giemsa was the sole procedure relied upon in the 1956 survey. The birds concerned were young, ranging in age from two to eight weeks. All belonged to the Central Iowa colony to which reference was made in the previous paper. A total of 114 blood films was examined, distributed by dates as follows: June 29, 32; July 21, 23; September 8, 33; September 18, 26. There were a few duplications among the birds examined on September 8 and September 18. The average ages (in weeks) of the squabs on the four dates were as follows: June 29, 4.7; July 21, 3.7; September 8, 3.6; September 18, 4.4. There were, in addition, two other young squabs which will be discussed later.
