We are very happy to welcome to southern California, Peter Pyle. A
publication Peter has been well known for that every birder should own
in their library, "Identification Guide to North American Birds, Part
I and II". Join us as he gives his presentation:
Discovering and Conserving Bryan's Shearwater
In 2011 a new species of bird, Bryan's Shearwater (Puffinus bryani),
was described by Peter and colleagues at the Smithsonian Conservation
Biology Institute, based on a specimen collected in February 1963 on
Midway Atoll, Northwestern Hawaiian Islands. It had been misidentified
as a Little Shearwater (P. assimilis) but genetically appears closer
to the Newell's Shearwater (P. newelii) of the Southeastern Hawaiian
Islands. During the winters of 1990-1991 and 1991-1992, a second
Bryan's Shearwater was discovered calling in a rock crevice near the
northeast corner of Sand Island, Midway, and photographed, videotaped,
and audiotaped in December 1991. These two records likely represented
prospecting individuals, and the locations of source colonies of
Bryan's Shearwaters has until recently remained completely unknown.
During the 1970-2000s there have been several reports of Little
Shearwaters in the North Pacific that may or may not have represented
mis-identified Bryan's Shearwaters.
Peter will present a history of the discovery of this new species
along with updated information on its seasonality, breeding habitat
requirements, and vocalizations based on the 1963 and 1991 records,
will review potential at-sea records in the North Pacific, and will
present recent exiting information on where Bryan's Shearwater
colonies may exist. (Where? You'll just have to come to find out.)
Bryan's Shearwater is undoubtedly rare and, if extant, will require
targeted conservation actions to increase it's population size. Peter
will present ideas on the next conservation steps to protect this
newly discovered seabird.
