White rock lake, near Poppy
First Glimpse
When I looked up at the nest, I caught my first glimpse of a fuzzy white chick. The nest is so high and the sides so built up, it is hard to see anything. The chicks head is on the right and you can clearly see a blue eye between two sticks. Getting big and already has some tail & wing pin feathers.

I'd been watching this nest since the male cooper's built it with the first sticks. This was taken 3 weeks earlier with mom in the nest: https://www.inaturalist.org/observations/48919232

While sneaking around barefoot in the canyon, I heard a commotion 10 ft. behind me. Thought I'd flushed a mourning dove, but it sounded larger. I moved my head around an oak tree to see a Cooper's Hawk on the ground, hopping away from me with a desert cottontail in its talons. I wasn't quick enough to snap a photo of the bird, but the ID is good.

Lighting did not allow for the best pictures. Near the eye cup of the binoculars you will see a puma track on the left and deer track on the right, both heading to the top of the photo. 2nd picture shows puma tracks on the left, deer tracks on the right.
