Hummingbirds and Rhododendron flowers

[Andrew Rozefelds]

To avoid any confusion I am sending this again - with the correct spelling
for  Rhododendron.

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

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

Would welcome any comments/suggestions back.
