For some species that have undergone a change in taxonomy since the beginning of the Breeding Bird Survey, trend results are presented for both the individual species as well as a "combined" trend that includes all data for the species complex. Users may wish to examine both.

These species complexes are:

Sapsuckers (Yellow-bellied/Red-naped/Red-breasted Sapsucker)
Traill's Flycatcher (Alder/Willow Flycatcher)
Western Flycatcher (Pacific-slope/Cordilleran Flycatcher): the majority of records in Canada are Pacific-slope Flycatchers
Solitary Vireo (Cassin's/Blue-headed Vireo)
Northern Oriole (Bullock's/Baltimore Oriole)
Blue Grouse (Dusky/Sooty Grouse): in 2006 the species was split into Dusky Grouse and Sooty Grouse. Results are presented only for the Blue Grouse species complex.
Western Grebe (Western/Clark's Grebe): in 1985 the "Western Grebe" was split into Western and Clark's Grebe. Results are presented only for the species complex; Clarke's Grebe is very rare in Canada and these results mainly reflect the trend for Western Grebe.
