AAV: genus-level, shown as caution · AAV leaflet "Protecting Your Pet Birds From Household Dangers" (the list "is not exhaustive"). The source names only the genus (Taxus), not Taxus canadensus specifically, so this is shown as caution.

Plants known to cause damage to the heart include oleander, yew, lily of the valley, and foxgloves.

peer-reviewed

Frontiers 2025 review: different species or genus-level, shown as caution · Review section "Toxic plants (miscellaneous)" on pet birds. The source names Taxus media (a different species or only the genus), not Taxus canadensus, so this is shown as caution.

Many ornamental plants are toxic, such as Coronilla varia, Ericaceae family (for example Rhododendron spp.), Kalanchoe spp., Nerium oleander, Taxus media, Digitalis purpurea, and Euphorbia pulcherima (81).
