A new species of warbler (Parulidae) from Puerto Rico
C. B. Kepler, K.C. Parkes
1972, The Auk (89) 1-18
The West Indies are among the best known of the world's tropical regions, and our knowledge of the distribution of indigenous land birds in the Greater Antilles has been thought to be nearly complete (Bond, 1956). The last new species from the Antilles were described in 1927, the results...
Copulation by California condors
S.R. Wilbur, J.C. Borneman
1972, The Auk (89) 444-445
Koford (Res. Rept. No. 3, Natl. Audubon Soc., 1953) observed sexual display among California Condors (Gymnogyps californianus) on more than 30 occasions, yet only once did he see what he thought was copulation.

Effect of Hygromycin-B on pigeons (Columba livia) with and without Trichomonas gallinae
R. M. Kocan
1972, Avian Diseases (16) 714-717
Hygromycin-B was administered in varied quantities to pigeons harboring nonvirulent Trichomonas gallinae and to pigeons free of T. gallinae. Both groups responded identically with large yellow caseous lesions in the upper digestive tract which superficially resembled canker (trichomoniasis). No mycotic association with the lesions could be established in...
Ethyl Mercury p-Toluene Sulfonanilide: Lethal and Reproductive Effects on Pheasants
J. W. Spann, R.G. Heath, J.F. Kreitzer, L. N. Locke
1972, Science (175) 328-331
Ethyl mercury p-toluene sulfonanilide (active ingredient of Ceresan M) at a dietary concentration of 30 parts per million (12.5 parts of mercury per million) was lethal to adult ring-necked pheasants. Egg production and survival of third-week embryos were sharply reduced when breeders were maintained on feed containing 10...
