Hey, that's a coincidence! I am often not as much priviliged to see such stunning views as Adrian provides us with and while birding in the field a lot of shrikes are seen more far off.
So even encountering some distant shrike sp. with obvious rufous tails (even far off obviously noticed) like some posible Red Backed Shrikes were not always eliminated, I called them 'Rufous tailed Shrikes'
Wonderfully no severe, negative critic was with me at the time..because now I find, not even a term like 'Rufous tailed' leaves some space for other Shrike sp.
