I went to Martin Park Nature Center in the morning to start a list for the Fall 2021 OK Bioblitz.
Nashville Warbler
BD: prominent eye ring, yellow underparts, grayish head indicate first Fall male

We've rarely seen Hairy Woodpeckers, so this male was a nice surprise.

Hairy Woodpecker

Switchgrass

Johnson grass
BD: note the terminal awns (stiff bristles) and the s-shaped bends where the seeds have fallen off. The seed head branches are at right angles to the main axis, not at an angle as with switchgrass.

Giant goldenrod (Solidago gigantea)

These American Crows had been mobbing something to the W of the park, but I never got a look at what it was.

Catalpa
iNaturalist IDd this as Southern Catalpa
(Catalpa bignonioides), but BD suggests
Northern catalpa, Catalpa speciosa
Unfortunately, I didn't take photos of the seed pods to estimate their dimensions.

Damselfly

This Carolina Wren was poking around a brush pile between the path and the creek.

Damselfly

At the end of my circuit, I saw this Osprey on the NE side of the lake, looking like it was drying its feathers after a dip.

From Martin Park, I drove over to the erstwhile 'Mustang Playas,' now known as N. Yukon Parkway. This Bald Eagle was perched on the W side of the road behind the cattle yard.

I drove E on Foreman Road to what Google and Garmin call NW 63rd and went north. There were some puddles in the road from the recent rain and they were getting a lot of action, including this pair of Brown Thrashers.

Common Pondhawk Dragonfly

I saw these birds through my windshield and shot a couple of photos, despite the distortion, before backing the car at an angle to get a better view.

One of at least two Gray Catbirds in the area

The Gray Catbird also wanted to use the water.

The Ruby-crowned Kinglet did not stay around for a better photo.

Nashville Warbler

This looks like a Northern Parula to me.

I think this is an Orange-crowned Warbler, bathing on the left, with a Nashville Warbler to its right.

Orange-crowned Warbler?

It looks like the Nashville Warbler was about to take its turn in the bath with another Orange-crowned Warbler queued up behind.

Male Downy Woodpecker

At the N end of the road, I found this Eastern Phoebe flycatching from a snag.

In the brush below the phoebe, this Lincoln Sparrow was hopping around.

Next I drove over to Sara Road and the Rose Lake area. There were dozens of Great Egrets and at least a dozen Snowy Egrets on the W side of the road.

Snowy Egret

About 40 American White Pelicans showed up overhead and then another 50 joined them; they circled, but I didn't see them land while I was there.

American Avocets

More of the Snowy Egrets

This big Snapping Turtle was in the water on the W as well.

At the corner of Sara Road and NW 63rd, this cicada flew into a bush.
BD: Prairie Cicada

Common Reed (Phragmites australis)
Along 63rd St, there were lots of these reeds along the edge of the water.
Considered invasive in some states.

Farther E on 63rd, there were 4-5 Scissor-tailed Flycatchers on the wire and fence.

At Morgan Road, a number of Turkey Vultures were perched in a tree on the E side of the road.

Farther S on Morgan Rd, I spotted an American Kestrel on the power line.

I went back to the house and decided to go into the back yard with the camera. This Ruby-throated Hummingbird was perched in the sunflower bed out the back door of the garage.

He tried out the Mexican Sunflowers...

...then the Cypress Vine...

...then he solved the riddle of where that pollen on the top of his head came from.

Out back, there were several Spotted Orb Weaver spiders like this one, that seemed to be wrapping up a meal.
BD: Neoscona crucifera--Spotted Orb-weaver Spider

Paper wasp
BD: Polistes apachus

Later in the day, Mary and I drove over to Lake Hefner to look around. This Yellow-crowned Night Heron was among the rocks on the E side of the flagpole area at Stars and Stripes Park.

At the time, we thought this was an Osprey at the pond on the S side of the lake, but after cropping and lightening the photo, it looks to be a Red-tailed Hawk.

American Coot

A pair of Mallards tucked in

Carolina Snailseed?

Great Egret, across the cove from the canal inlet

Near the covered fishing pier on the S side of the lake, we spotted this dark ibis among a bunch of ducks and coots.

BD: Pale stripes on sides of undertail coverts, lack of BWTE white eye arc

Neither the ducks nor the ibis seemed to be concerned about my getting out of the car to get a photo with some better light.

The American Coot seemed to be demonstrating it too could stand on one leg.

The pinkish skin around the eye seems to indicate White-faced Ibis.

We finally left the ibis and drove W to find this Great Blue Heron.

Juvenile Forster's Tern

Great Egret

We drove to the W end of the canal and found several Black-crowned Night Herons.

We drove around by Prairie Dog Point and, as we turned back N to get on the dam road, this juvenile Cooper's Hawk watched us from the trees to the east.
