PETER PYLE  [Peter B. Pyle]
Peter Pyle is of a slightly younger generation than all the rest of our 'top 40' selection, and he would become increasingly important in California birding circles in the 1990s. [He only looks 'older' in the photo because it is a recent 2002 shot]. Indeed, a quick glance at a selected list of his publications (below) shows just how much effort and energy Peter expended on important questions of bird identification, biology, and ecology after the close of our period of review in 1989. However, Peter was an active field biologist working for Point Reyes Bird Observatory on S.E. Farallon I. from 1980 on, and he would become the premier biologist there in due course (working not only on birds but pinnipeds and Great White Sharks). He was selected for our 'top 40' because of the publication of his very important book in the late 1980s (Pyle et al. 1981): his first banding guide to North American passerines. It revolutionized the bird-banding world, making accessible a plethora of in-hand criteria. These details would also prove to be of great use in the field identification of birds. From its publication, North America had an in-hand guide equal to those available in Europe. Over the course of time, with additional experience and extensive museum research, Peter would replace this first guide with a tome twice as thick: Pyle (1997b). But that is after the end of our period of review.

Peter grew up in a birding family. His family, Robert L. Pyle, is an internationally known bird observer. Bob Pyle served as a Regional Editor for Audubon Field Notes in southern California before our period began in 1965, and continued as AFN/AB editor for Hawaii after moving there in 1966. Bob Pyle became one of the premier field observers in Hawaii, and Peter grew up there under his dad's tutelage. Peter's expertise extends not only to Hawaiian birds, but to the landbirds of Micronesia and the seabirds throughout the Pacific. Since joining PRBO, he has not only been the biologist on the Farallones, but has conducted numerous seabird surveys throughout the Pacific.

Significant bird records: numerous vagrants on S.E. Farallon I. were found by Peter; the most important in our period were
  • Dusky Warbler  27 Sep 1980  S.E. Farallon I., S.F. first CA record [co-finder]
  • Ruby-throated Hummingbird  21 Aug 1985  S.E. Farallon I., S.F. 2nd CA record [co-bander]
  • Yellow-bellied Flycatcher  3 Sep 1986  S.E. Farallon I., S.F. 3rd CA record
  • Veery  26 Sep 1985  S.E. Farallon I., S.F. 5th CA record
  • Yellow-bellied Flycatcher  8 Sep 1989  S.E. Farallon I., S.F. 5th CA record
  • Black-billed Cuckoo  18 Oct 1985  S.E. Farallon I., S.F. 7th CA record
  • Gray-cheeked Thrush  26 Sep 1986  S.E. Farallon I., S.F. 8th CA record
  • LeConte's Sparrow  11 Sep 1986  S.E. Farallon I., S.F. 9th CA record
Peter would be involved in many important records after 1989, including Stejneger's Petrel  (14 Nov 1990, 2nd CA record), and a host of rarities from the Farallone Islands.
