Another 5 pictures from Westmoreland Park.
This bird looks like a 1st cycle Glaucous-winged Gull. There are some gray mantle feathers coming through. Its massive size isn’t really conveyed well by the picture.
Another pigeon. This diminutive bird looks good for yet another 1st cycle Thayer’s Gull. This bird is overall very pale
This bird, even though it is facing again and doesn’t show its profile very well, has a blocky head and a honking bill. A good candidate for a 1st cycle Glaucous-winged Gull, but there are some dark streaks in the primaries, which makes it Olympic.
This 1st cycle bird was really white. The bill color is wrong for a pure Glaucous Gull as it would have to be nicely split pink-black. The bill size is unfortunately too large to consider Iceland/Kumlien’s. The tertials of 1st cycle Iceland/Kumlien’s Gulls are usually nicely patterned which is also not the case here. Just doesn’t look like your typical Glaucous-winged Gull. On Glaucous x Glaucous-winged hybrids, the bill is usually bicolored, but the border between the pink and black bill is ill-defined. Could this be a Glaucous x Glaucous-winged Gull with an all black bill? The bird’s size was maybe a little smaller than a pure Glaucous-winged which might support the barovianus heretage hypothesis. The bill would be ok as well. Please feel free to comment …
This Olympic Gull was perched up really close to me for a little while on the rails of one of the wooden bridges.
