There are a gazillion resources out there, both printed and digital, and many of them are excellent. The following are just a few:
iNaturalist One of the best ways to identify species if you’re a digitally minded person who doesn’t mind signing up to use an app. This data-sharing community crowdsources identification; post a picture or several of a species and the app will offer you likely matches; these may be confirmed and refined by other members of the community. Findings are shared with scientific data repositories.
Groups can make use of iNaturalist productively. BC Parks has set up a project so that citizen scientists can generate data about the species found in their parks.
The CornellLab of Ornithology has an excellent online resource and a companion eBird citizen science app.
The Outdoor Recreation Council of BC has a Guide to Birdwatching in BC.
Biodiversity of BC offers online E-Flora and E-Fauna atlases.
Biodiversity of the Central Coast A bit further north, but much still applies, and they offer an excellent list of species identification resources.
