It's right up there with the Endangered Species Act, and perhaps more important for birders since the latter only protects birds that are on the verge of extinction.
In plain-speak, the Migratory Bird Treaty Act improves the odds of adding more species to your state and county lists, every year, by providing basic protections for EVERY migratory bird species in North America.
I really can't imagine why any Oregon birder would consider this to be "off-topic." Protection for migratory birds is a central issue for Oregon birders.
Good birding, Joel
Apologies for a non-birding post, but I thought if someone responded to this it might not spin out of control. There are at least two Migratory Bird Treaty Act (MBTA) issues out there, one in Congress and one by rule making by the Department of the Interior. I suspect you are thinking about the second, which changes the rules as to "incidental" taking of a bird. Currently, the regulations prohibit such takings (without a permit), which are when some legal activity harms birds but not intentionally. For example, a wind turbine may kill eagles but not on purpose, even if it is highly likely. As another example, windows in your house are not intended to kill birds. Broadly speaking, the new regulations would not apply to incidental takings. -- Joel Geier Camp Adair area north of Corvallis
