Whitewater Draw Weekend

With Winter firmly ahold of us (temps in the 60s!), it was time to plan a birding trip to Whitewater draw. I've posted about our many trips there a couple times a year for nearly a decade since we discovered it. In recent years, Arizona Game and Fish have installed a webcam to keep an eye (and ear!) on the action there. This year showed a LOT more water than in the last few years. I'm not sure it is from more rainfall or if the irrigation system is working again after failing a few years back. It sort of put a crimp on the cranes the last few years, so was looking forward to seeing the place again.

I ended up going out both Saturday AND Sunday! There were lots of cranes, but interestingly, they were all avoiding the water! Years past they all gathered in the shallow water to avoid predators (coyotes) through the night, but now they gathered on the banks. But this behavior brought them closer to the walking path, so was able to get some good close-ups.

The main activity besides resting (feeding is generally done in fields away from the wetlands), as well as male posing, presumably looking for females, or exerting dominance. The pair of males shown here were trying to out-do each other. I was in the perfect spot for the photo at left where they were standing tall with wings outstretched - mirroring each other. The left image is a full-resolution blowup to show the steely gaze of the crane looking my way.


It so happened that I was set up next to 2 other photographers - all of us shooting with the same setup - Canon cameras with the 500mm and 1.4X extender! I was the only local one. Anyway, the two cranes continued their antics shown here. At right, one went low the other high, and finally at right it appears the confrontation was over. I wasn't sure which one won the contest, but I'm sure that THEY did!

The group of cranes adjacent to the walking path was closest to us, but was small in numbers compared to the main group which seemed to the west side of the wetlands, about a quarter mile or so away. They were raising quite a racket out there, and in binoculars, seemed again to be avoiding the water. Some snow geese were, as usual, scattered among the sand hill cranes.

I love their rattling calls. If you tune in to the webcam above, you can hear them. On occasion when something causes them to take to the air, the show starts when you hear the wing beats of thousands of cranes taking to the air, then the ruckus starts with the calls also filling the air. I can sit and watch/listen for hours, which I generally do - occasionally taking a photo or two!

At left, the view is towards the west - the large groups of cranes can be seen at bottom, with many taken to the air, seen in silhouette against the Mule Mountains. The lowlands contain fields where the cranes often congregate.  At right is a view to the northwest, again seen against the mountains illuminated by a very low sun.

As has happened a few times in the past, as sunset neared, there appeared a "tornado" of blackbirds, rushing in huge groups to congregate in the reeds and rushes around open water. Upon closer examination, they were, in fact, yellow-headed blackbirds. At left they are seen as they gather, with cranes in the background. They are evidently close cousins of the more common redwing blackbirds, but Whitewater is the only place I've seen the yellow-headed version.

There were many other species of birds feeding. Here at right are seen a group of American coots taking one last feeding trip across the wetlands before it got dark. Only seen in silhouette here, they sport nearly white beaks and dark red eyes, making them more striking in full sunlight...


I had spotted a great blue heron as we entered from the parking lot, and right on cue at sunset, it flew right in front of me to roost in a clump of vegetation not 50 yards away. In the deepening twilight, the exposure was long enough that the wing flaps were blurred, but in scanning to follow it, at least the pupil of the eye is still sharp!

The usual routine was for the cranes to return to the protection of the water as nightfall came. Many took to the air and flew nearby, and it is always a challenge to capture them against the twilight sky. At right is about my best effort as they were gliding without flapping their wings. Even as it got dark they were sharply captured.


I'll have to say, that Saturday's twilight was likely the most spectacular I've ever seen! Of course, there are a lot of those in AZ, but this one was very long-lasting, actually 45 minutes of color from looking at the time stamp on my images. I've got 2 to show here, at left a single image showing some of the birders here distracted by the sunset colors. And at left is a 3-image "HDR" (High Dynamic Range) photo that combines different exposures to extend the visibility of highlights and shadows...


It was clear enough on Sunday to take a few
star photos.  The big news in astronomy now is that in the constellation of Orion, the upper left star, Betelgeuse has been growing fainter than it has ever been seen!  Instead of the brightest star in the prominent constellation, it is now third-brightest, effectively tied with Bellatrix, the upper right star.  At left I took a photo purposely out of focus to show the colors of the striking constellation.  The orange color of Betelgeuse reveals it to be a red giant star - very cool (thus orange-colored) compared to the bluish other stars of the constellation.  At right is another not quite as far out of focus to show much fainter star colors.  While most are still blue, many fainter ones have reddish colors as well.

I've only started to harvest images from these 2 trips, so look for more soon, as well as likely more trips while the cranes are here!
