"Peter Paul Kellogg, 76, cofounder of the Laboratory of Ornithology at Cornell University, died Friday at Rosewood General Hospital, Houston, Tex., after a long illness.
  Recognized as an eminent recorder of bird songs, Professor Kellogg retired from Cornell in 1966, but returned the last three summers to participate in field courses in ornithology.
  Mr. Kellogg recently was working with graduate students at Rosewood Hospital in research to develop colored X-ray techniques.
  He was also on the hospital's board of directors.
  He was assistant director of the Laboratory of Ornithology, a life member of its administrative board, and a director of the Cornell Library of Natural Sounds, one of the largest libraries of its kind in the world.
  Mr. Kellogg received a bachelor's degree from Cornell in 1929. From 1929 to 1938, while working on his doctorate, he was an instructor in the State College of Agriculture.
  Upon receiving the degree, he was appointed assistant professor of ornithology, and in 1953 was named professor of ornithology and biological acoustics.
  During World War II, he was director of the Western Electric Radar School.
Mr. Kellogg was also on the editorial board of "The BioAcoustics Bulletin," a quarterly published by the Laboratory of Ornithology.
  In this field, he worked on the spectrographic analyses of bird sounds, anatomical studies of the vocal apparatus of birds, and bird navigation."
