As far as I know, Cedar dust is associated with lung and upper respiratory disorders and irritation, as well as eye irritation and swelling, and also tends to cause skin-rashes in birds as well...I know that "Red" Cedar is far stronger than the other species of Cedar, such as Yellow Cedar, but all types of Cedar are known to cause the lung and eye irritations and swelling in birds, as well as the skin rashes. It's the dust from Cedar that usually causes the lung and eye issues, and the rashes I believe come from just contact with their skin. It's due to the oils in the Cedar, mostly Phenols.
Pine wood actually contains very high levels of Phenols as well, which cause the exact same issues that Cedar does: skin rashes on-contact with their skin, and then the dust causes lung/respiratory irritation and swelling with breathing issues, and then also eye irritations.
it happens )
