Computer-assisted Birding

Posted by: Rick Wright | Comments (2)

I love the idea that a computer program could help you identify your birds. The only problem is, of course, that it doesn’t work.

I got a note this morning about a new online program, and decided to give it a try. Like all the others out there, this one is basically a key, leading the user through a series of usually dichotomous choices (“Bill: all-purpose or cone-shaped?”), each of which serves to eliminate possibilities until you arrive at an identification. 

I decided to ask the machine to help me identify the Townsend’s Solitaire Darlene and I had watched drinking at Catalina State Park late Monday afternoon. And I played it straight all the way, too, giving the program the “right” answers even when a truly puzzled birder might not have known, say, the length in inches of a study skin of the species.

And where did this marvel of technology lead me? To Varied Bunting, of course! Oh well.

Endothermy: Why Not Give It a Try!

Posted by: Rick Wright | Comments (2)

Greater Roadrunners are some of the strangest birds around, and that’s really saying something in the land of Gambel’s Quail! While most birders’ mental image of a roadrunner is of a streak running down the road (duh), if you’re out early on a cool morning, this is the picture you’re likely to see: a great disheveled mass of streaky feathers and blackish down raised to the sun. Normally wily as a coyote, roadrunners are exceptionally approachable when they’re recharging their solar batteries of a morning, and this one let me get so close that for a panicked moment I worried that it had mistaken me for something edible.

Longspurs 3, Owls 2

Posted by: Rick Wright | Comments (0)

It was a perfect prairie homecoming today. Gary, Chris, Mark, and Molly discovered a Lapland Longspur yesterday on the Sonoita grasslands near Elgin, and there was no way I couldn’t look for that bird, a species with fewer than 20 records ever for southeast Arizona.

So Darlene and I bumped across the pastures on a dramatically windy afternoon, finding the described site and, a pleasant surprise indeed, Erika and Marjorie hunkered down in the lee of a stock tank. A couple of hundred Horned Larks were feeding among the cowpies, and goodly numbers of Chestnut-collared Longspurs joined them, their musical little chirrups chiming each time the flock shifted position.

Most of the Chestnut-collareds were females or drab males, but a few were showing the black of breeding dress concealed beneath their pale feather edges.

I was particularly excited to find at least 4 McCown’s Longspurs in the flock, a bird I know well from its breeding grounds in northwest Nebraska but one I have rarely seen in winter; it was outstanding to see them with the Chestnut-collareds and to firm up my shaky impressions of their face pattern and bill shape.

Marjorie and Erika had been holding down the fort long enough to be cold in the biting wind, so they headed out. Darlene and I continued scoping the flock, and 45 minutes later a dazzlingly bright male Lapland Longspur appeared. He fed among the grasses and the cowpatties for a good 20 minutes, apparently unaware of how intensely he was being admired. Gary has posted beautiful photos of the bird at azfo.org, but I was reduced to a miserably poor effort at digiscoping; still, the bird is identifiable as it peeks over the cowflop in the glare of a shakily held camera.

Well, maybe ‘identifiable’ was an exaggeration, but he’s in there!

So what to do after that wonderful experience? The clouds and the light over the mountains drew us over to the San Rafael grasslands for dusk. Northern Harriers were gathering to roost, and the last Mourning Doves and Lilian’s Meadowlarks were on the roadsides. It started to rain, then to snow, but like ornithological mailmen, we were undeterred. As we drove the dirt roads slowly in the gloaming, we flushed first one, then another, then a total of at least four Short-eared Owls. Our last bird of the day was a Burrowing Owl, standing on the road in front of the car, bobbing slightly on its stilt-like legs before it too lost itself in the tall grass.

Ducks in Love

Posted by: Rick Wright | Comments (0)

To human eyes at least, a lot of duck behavior is, shall we say, not quite consensual. But it isn’t for lack of trying on the males’ part. This time of year, the boys are on their best behavior, dressed in their finest finery and pitching fevered woo at just about anything feathered that floats past.

My favorites of the moment are the Green-winged Teal, and their hoarse little whistles are the dominant sound of wetlands large and small across the continent right now. Like most puddle ducks, the drakes assemble in, well, gangs around the demure females, and when the spirit descends, they go into full display, tossing their colorful manes and rising out of the water to show their white bellies and shocking green speculum.

Now be honest: could you resist these handsome rascals if you were a female teal?

Team Birdwatch!

Posted by: Rick Wright | Comments (0)

Tucson Audubon’s “urban guerilla” birding team was out at Reid Park this morning, enjoying the birding and, even more, enjoying showing other people the birds.

It’s always exciting to see how interested people really are when you stop and talk to them about birds. And we had some good ones to show them today: Harris’s Hawks, a snazzy Belted Kingfisher, and an outstanding selection of up-close ducks including Canvasback, Redhead, Ring-necked Duck, and Lesser Scaup.

Watch for the team to show up in your favorite city park sometime soon!
