The first bird we managed to get a photo of was this male Painted Bunting at Lake Elmer Thomas dam.

He did sing for us.

At Lake Elmer Thomas dam, we heard, but didn't see many birds. Mary got a photo of this damsel fly.

Sea oats?

Wavyleaf Thistle
We used the iNaturalist app to ID some of the plants.

False Goldenaster

Mary found lots of wildflowers to photograph along the road through the Mt Scott picnic area.

At Mt Scott picnic area, Mary caught Shelly looking for one of the Black-capped Vireos that kept eluding us most of the day.

In the Mt Scott picnic area, we saw this male Summer Tanager.

In the same area, this Blue-gray Gnatcatcher was catching insects, perhaps for nestlings.

As I was walking back to where we'd parked the car at the picnic area, I saw a pair of Northern Cardinals and got a photo of the male.

Hedgehog Cactus (Echinocereus reichenbachii ssp. baileyi), among the grasses and rocks behind the Holy City gift shop

Mary and I took nearly identical photos of the cacti.

Mary got a variety of views of the yellow-blooming stonecrop.

...and Shelly among the wildflowers.

On a power pole behind the Holy City gift shop, this male Red-headed Woodpecker posed for a photo.

I'm not sure what this oddly-posed bird is.

We had hoped to see a Zone-tailed Hawk that had been reported in the area, but that had to wait for our third trip to the area; today we only saw Turkey Vultures.

After we had walked all around the Holy City gift shop, this male Black-chinned Hummingbird finally made an appearance near the feeders.

As we left the Holy City area, we spotted this Dickcissel on the wire.

Near the Dickcissel was a Barn Swallow.

DYC - we learned later that these difficult-to-ID flowers and their ilk are called "Darn Yellow Composites"

After leaving the EEC, we went to the Sunset picnic and trail area.

Meadow Pink

We hiked up the trail, where Shelly and Mary stopped at the little dam beside the trail.

We saw several Eastern Collared Lizards (state lizard of OK) along the trail; Mary and I took lots of photos.

Mary and Shelly took the direct route back down the trail while I tried what I thought might be a short-cut. It may have been, but I got distracted by 3 Collared Lizards, a male and 2 females. I first spotted the male, who seemed to be surveying his domain from the top of a rock above me.

Then I noticed this female closer to me. I thought she and the male were considering each other.

Then another female came up behind the male.

He went down to her to get a closer look.

But apparently the chemistry wasn't there.

The other female didn't seem to be impressed either; she stayed where she was.

The male went back to his post.

When we got back down the trail, we spotted what seemed to be the same lizard we saw on the way up.

We stopped at the Sunset parking lot to look for the hawk again, but found a Painted Bunting again.

As we headed back east on the main highway, we saw this Northern Rough-winged Swallow.

And another Dickcissel, singing
