Some of them are new to me. This is a chestnut-collared longspur, keeping watch on a boulder near the gate of the park.
And this...well, it's definitely one of the Accipiter hawks. Telling Cooper's and sharp-shinned hawks apart is a challenge for people who see far more of either species than I do, but I'm tending towards the latter here, if only because the legs seem quite long and the head quite small.

And the raccoons are still curious!
