Steve has found four of these hybrids and notes:
"Each time, it was the combination of no shoulder spur (the little black spur extending down just behind chest in Barrow's) and an intermediate scapular/wing-covert pattern that has caught my eye.  Unlike the facial spot, the differences noted above can be seen from a fairly wide variety of angles and a fair distance."
