Two birds, called in.
One clearly has an eye stripe with white eyebrows = mountain chickadee.
The other (last photo) seems to have the full black cap = black capped chickadee.
Loggerhead or Northern Shrike?
Several thousand? I'm not experienced at estimating large flocks like these.
This striking white pigeon was at the same spot for about 2 hours--perhaps an escapee from a pigeon fancier's collection?
The city in the background.
It was a great day of chilly wind and light mist, but not enough to be too bothersome to either people or ravens. Watching them fly as pairs, playing, was a treat. This was a rare moment on the ground.
subspecies Cyprinus carpio haematopterus?
Common along river. No leaves at this time of year, just the very conspicuous berries.
Unsure between the native bittersweet (Celastrus scandens) or the oriental one (C. orbiculatus). Based on the USGS website below, I think the bright yellow capsules (rather than orange) and the berries along the branch (rather than just at the tips) indicate the exotic, unfortunately.
