Here is a closer view. It is a crested caracara, based on its black cap, reddish face, white neck transitioning to black feathers and yellow feet. It is a bird of prey, as its appearance shows, although it can also scavenge. It is comfortable on the ground, and this bird is obviously comfortable rather close to the ground.
I will try to get a closer and better photo. I took this from the road, with my zoom, in late afternoon low light on a cloudy day, without a tripod.
This week we are showing some more photos from our recent trip to Yosemite National Park on our Viva la Voyage travel photo site.
