I received a email from Terry McKee concerning old CBC reports mentioned on OKBIRDS list, mentioning Texas wrens and White-rumped shrikes. So I did a little research. It would appear the Texas wren is the Bewick's wren and the white-rumped shrike a subspecies of the Loggerhead shrike. It can be confusing when names change over time. But no worse than the lumping a splitting of species that happens every year.
