Regarding the re-constitution of species like Baltimore and Bullocks
Orioles, Rufous-sided and Spotted Towhees, etc., does anyone know
why? 20-3 years ago, we were all informed that according to expert
opinion the latest research had proved that these were single species
with interbreeding populations, etc. Now expert opinion tells us they
are good, separate species. What happened?
