觀察細節

Originally logged as Eared Grebe, but changing to Horned Grebe after reviewing photos. Sharply contrasting clean-cut facial plumage, flat head with slight rear peak. White tip to bill distinguishable in one photo. Seen twice, 30 minutes apart - but potentially two individuals (photos from second spotting seem to have more white between bill and eye, but it may be the light)? Seen around space 5 in Primrose Point area.
