A robin was joined by a Dark-eyed Junco in the foreground.

Blue Jays are throughout the park but don't seem to want to stop long enough for a decent picture lately.

female, along with the American Robin, probably the most prevalent birds in the park right now

female and male

this one came flying up the creek a few feet from us and landed on tree branches up the creek

These two tried to join several other pairs of Mallard at an isolated pond but the others were not very receptive and chased them over to where the turtles were on the other side.
