   May 2002 - The taxonomic order, common names and four-letter codes included in this web version of the Squamish Estuary Bird Checklist published in 1997 have been updated using the 7th edition of the American Ornithologists' Union (AOU) Check-List of North American Birds (AOU 1998) and its supplement (AOU 2000).

Bird Tracks

The following is a list of the bird species that may be observed in the Squamish Estuary. The status of each species is indicated by an abundance level in each of four seasons. The standard four letter code is shown for each species.

The checklist area includes upper Howe Sound north of a line from Britannia Beach to Woodfibre, and all of the Squamish River floodplain south of the Mamquam River.
