Hummingbirds and Rhodendron flowers

[Andrew Rozefelds]

Are there any records of Hummingbirds being poisoned after ingestion of
nectar from Rhodendron flowers?

Rhodendrons are known to be poisonous. The nectar contains grayanotoxins
and  honey produced from Rhodendron flowers is known to be poisonous to
humans.

Would welcome any comments/suggestions back.
