Observation details

Adult hybrid with Clark’s mate and backcrossed offspring. Adult did not look too off for a CLGR, but had dark extending to top edge of eye. I could have passed it off for a Clark’s with maybe some distant Western heritage, but the offspring have extensive dark around the eye. Photos of both, along with the Clark’s to add.
