What’s outdated about the fact that Couch’s is being increasingly
documented moving northward as a vagrant throughout the country? Yes vocals
have shown that most records in Oregon have been Tropical, but vocals have
shown and will continue to show that Couch’s is becoming more regular
country-wide.

If you don’t hear these birds calling, they cannot be identified; that’s
the simple conclusion to this topic. There’s nothing controversial about
it.
