Lanius ludovicianus

ID tip from David Sibley re this shrike:

"The pale tips on some greater coverts are a sure sign of immaturity -
adults of both species have uniform glossy black wings. Therefore the
extensive and solid black mask makes it a Loggerhead, since all
immature Northerns have narrow and incomplete masks and the only
Northerns with a mask approaching this are adults."
