British Columbia Rare Bird List: Casual and Accidental Records th July 15, 2018: 5 Edition compiled by Rick Toochin, Jamie Fenneman, Paul Levesque and Don Cecile. Comments? Contact E-Fauna BC The following is a rare bird list of the casual and accidental bird species that have been recorded within the boundaries of British Columbia. The taxonomic order follows the American Ornithological Society’s Fifty-eighth supplement to the A.O.S Check-list of North American Birds (Chesser et al. 2017). There are no previous publications available that list all of the records in one document. Skin specimens, photographs, tape recordings, and/or adequate field notes document many of these records, and with the introduction of digital cameras to birding in the early 2000s many records in the past 10 years have been photographed; however, field notes remain extremely valuable and, particularly as some of these records are solely substantiated by field notes. In the case of records with no supporting documentation, the records are listed as “hypothetical” and are separated from the better substantiated (“confirmed”) records. In addition, for several species the identification is correct, but the origin of the bird may be in question; these species are also considered “hypothetical” here. With the introduction of chat groups in 1999/2000, as well as personal birding blogs in the mid- to late 2000s, there are many more outlets to share and document birds today than in prior years. In many cases, digital photos accompany reported records, rendering the decisions of records committees almost obsolete for many sightings. These committees do play an important function in the review of records, however, as they provide an objective platform to help separate well-documented, and presumably accurate, records from those that are less reliable. This document is intended to provide an unbiased synopsis of all historical and recent rare bird sightings in the province without attempting to take on any of the roles that would normally pertain to a Rare Bird Records Committee. In the interest of providing the most complete and accurate information possible, all observer names have been included for each record, as well as any reference material that provides the information source from which the record has been extracted. Note that, although an attempt has been made to include all reported occurrences of the species in question, it is anticipated that additional sightings have occurred, but have been overlooked. Readers are encouraged to pass along any observations that are not included here, or any corrections to the information that has been provided, by contacting e-fauna BC. List on Document of Accidental / Casual Species The following species are considered casual or accidental within the boundaries of the Province of British Columbia. These species are very unusual to the region. To be considered a species of casual occurrence there have been between 20-100 records historically, often occurring at a particular time of year, but they normally are reported less than once a year (or are infrequently reported each year as is the case with some deep ocean pelagic species) and in some cases these birds are reported a few times in a ten year period. In the case of an accidental species there is often only a single record or up to 20 records with the occurrences of a species going several decades or much longer before reoccurring. These species are considered extremely unusual in British Columbia and are always in need of documentation. For any casual or accidental species to be put on this list they are considered far out of range and are extremely rare in their occurrence within the boundaries of British Columbia. For the purposes of consistency the first 100 records are listed on this list. If a species has more than 100 Provincial Records then it appears at the end of the list in a separate section. To make this list as complete as possible other records have been included on the list such as birds that are currently subspecies that have occurred as rarities to the Province, birds where the origin is unknown and hypothetical species where the identification might be correct, but there is only written field notes that document the record. Any species found on the list should always be documented when encountered, as they are extremely unusual at any time of year in British Columbia. Tropical Kingbirds are annual on the West Coast of Vancouver Island, but everywhere else in British Columbia this is considered a very rare bird to find. This bird was found and photographed at Jordan River during the peak period when this species is known to occur the month of October. This Tropical Kingbird was found in Jordan River and photographed on October 19, 2009.

This bird was photographed in the late spring to early summer period at the Iona Island Sewage Ponds in Richmond during the peak time when this species has been encountered in British Columbia. The photograph was taken on June 23, 2000.
