Occurrence Remarks The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. Another observer was Cecile Thompson. | Elimination of similar species: Evening Grosbeak by the bill & color pattern. White in the wing too extensive for young Orchard Oriole. Also seemed bigger than an Orchard Oriole. Bright yellow underparts & streaked back rule out several other orioles. Immature Scott's are described as 'gray-green' below. | The original documentation form event occurred around mid-afternoon.
