I spent the AM hours at Riverlands Migratory Bird Sanctuary and Columbia Bottom C.A. yesterday. I mostly ran into lots of the usual: waterfowl, American Kestrels, Harriers, Eagles and an assortment of Sparrows. Two birds at RMBS were a bit unusual. The first was this juvenile, “Krider’s morph” light phase Red-Tailed Hawk. I watched him at this perch for a while until one of the resident Eagles decided it was time for him to leave the tree. I looked for him the rest of the morning, both at RMBS and CBCA, but never spotted him again.

The other bird that drew my attention was this guy below. I am making no sure statements as to what this one is. It mostly reminds me of an aberrant Canada Goose, i.e. partial leucistic. However, the orange legs remind me of a Greater White-fronted Goose. Perhaps a mix of some kind? Hopefully the experts can shed some light…
