For miles and hours driven by car, set your odometer to zero when you enter your area (not when you leave home). Anywhere you drive within your area counts, as you are theoretically able to spot birds and count them as you drive between birding spots. Keep a note of the time you enter your area of the CBC circle. Then write down the time every time you hop into your car and the moment you hop out of your car. At the end of the day, you can add up these times to get your party-hours by car. The odometer reading when you leave your area is the party-miles by car. Let's say you entered your area of the circle at 7:30 a.m. and departed for the countdown at 5:00. That's a total of 9.5 hours. If you add up the times you spent in the car and it comes to 1.5 hours total, then you have 1.5 hours by car.
Hours and miles on foot are a bit more difficult, because this is when groups split up into multiple parties. If you never split up, then using the example above, you logged 8 party-hours on foot. But if you split up into different groups (parties), then you have more. If you were apart for just an hour of the day, you'd have 9 party-hours. It's that simple. And a party is one to several people birding together within earshot.
As another example, say your group is 4 people. You split up, with one person hiking up one canyon, another person hiking up another, and two people hiking down yet a third. You all meet back up 2 hours later. Using the example above, the base is 8 party-hours, You have to add two more hours for each of the extra parties, so that makes a total of 12 party-hours by foot for the day.
My favorite source of weather info is the NOAA Western Regional Headquarters site. This link HERE will take you to the exact center of the AZAH Circle forecast.

I think Sara and I were the only team to not actually see a live Montezuma Quail, though we did hear a covey early in the morning in Peck Canyon. But in Pine Canyon a Cooper's Hawk dropped this at our feet as it flew right by us, startled at the first humans it must have seen in weeks.
There have been reports from birders in recent weeks to indicate that the population is still pretty high, but I'd be surprised if we saw as many as last year. The monsoon was not very good in most of Southeastern Arizona and plants (and the animals that eat them) have suffered.
So I thought a couple tips on finding them might be in order. Their preferred microhabitat seems to be open oak woodland with a grassy understory, especially on the slopes within 50-100 yards of the canyon bottoms. So walking along the slope parallel with a wash, but a 25-50 yards upslope will increase your chances of flushing a group.
Better yet, when you are near such likely looking habitat, whistle for them. The whistle to use is a series of 4-8 pure, downslurred whistles, which is the female's call. Interestingly, the males will respond to this with their single downslurred, buzzy whistle better than to their own song. A recording of this female call can be heard on the Keller SE Arizona CD. It's the first sound on the cut, the first time simultaneously with a male's song, the second time on its own. I usually hear the individual notes more spaced out, rather than in a stuttered pattern as on the CD.
We may do a quick count of numbers at the countdown of this and other target species to see if we've come close to previous highs.

Well, one reason we missed it was that it was just a bad year for many sparrows. We also missed Grasshopper Sparrow and had only 7 Brewer's Sparrows, after all. But there was one thing we didn't do.
In the wake of last year's CBC, I had some interesting e-mail conversations with Scott Mills, who was the compiler of this count through the late 70's, 80's, and early 90's.
Says Scott, "They respond really well to playbacks of taped songs in winter - they apparently hold territories and chip like crazy (and often come to the tape) when a song is played. The first year I tried it I got something like 45 birds with tape in an area where I had flushed only two simply by walking through the grass."
He mentions Wise Mesa and the steep upper edge of Atascosa Canyon (in area 10. Bear Valley Ranch) as being especially good areas. One winter I flushed a few in the open, scrubby mesquite slopes on the east side of Arivaca Lake. I suspect there are some in every area of the circle in the right habitats. The grassiest areas with very scattered mesquite are the best. And although I'd like to have a calm, warm, sunny day, he reminded me that in snow, many of the skulking sparrows (including Grasshopper and Baird's) are seen perched in shrubs.
So, now in addition to your GPS and digital camera, don't forget your iPod and external speaker.

On last year's CBC, Andrew Core was able to get these simple and more-than-adequate shots of a Greater Scaup that he and Jeff Gilligan flushed from Papago Tanks, a pair of obscure ponds north of Ruby.
So, along with your binoculars, food and water, don't forget your point-and-shoot digital camera.

On December 15, 2008, 56 participants in 21 teams found an all-time high of 139 species. It was a great day that will be hard to beat.
Of special note were the addition of eight new species to the all-time list. They were:
Whiskered Screech-Owl (long overdue)
Also, we broke all-time national record high counts for five species, more than any other CBC in 2008. They were Montezuma Quail, Elegant Trogon, Painted Redstart, Hepatic Tanager, and Scott's Oriole. For the numbers, see the list below. Of special note was Hepatic Tanager – the count had recorded four in three different years, and that was previous all-time national high. So our 27 was simply amazing. The Green Valley CBC was the next closest count, breaking three all-time national highs, including Painted Redstart, edging us out with 17 of them.
We hold the all-time national highs for six additional species. They are:
Mexican Jay – 1110
Bridled Titmouse – 574
Rock Wren – 300
Canyon Wren – 213
Rufous-crowned Sparrow – 460
Five-striped Sparrow – 6
In 2008 we had the annual national high count for Arizona Woodpecker, Hammond's Flycatcher, Gray Flycatcher, Ash-throated Flycatcher, Rock Wren, Canyon Wren, Black-throated Gray Warbler, Rufous-crowned Sparrow, and Five-striped Sparrow.
In comparing counts made on this CBC since 1960, we broke or set new high counts for 45 species, listed below.

One bit of info I would tweak to fit the Atascosa Highlands CBC is which species of owls to imitate (or play tape/iPod of, if you don't whistle). Our Northern "Mountain" Pygmy-Owl toots 100 times per minute, not the 20-25 of the Pacific Northwest birds; often the notes are paired into double-toots, but not always, and still average out to 100/minute. Furthermore, screech-owl imitations are just as effective, if not more so in much of our area. Both Western and Whiskered Screech-Owls are common in the circle, and in addition to stirring up mixed flocks of Bridle Titmice, Ruby-crowned Kinglets, and the occasional Hepatic Tanger pair, you may also get a daytime response from a real owl. Keep in mind that Whiskered Screech-Owls tend to be in larger, denser stands of oaks, and Western Screech-Owls are usually in more scattered, open woodland with lots of open area between the trees.
The countdown is simply a reading of the list of expected species to find out what birds were seen during the day. Everyone present simply calls out "yes" if they have seen the bird mentioned. After a preliminary species total, each group will then have a chance to mention their highlights and add any species not called out. Then after that, we'll have a total species count for the day.

This is the restaurant with the façade shaped like a giant cow skull. The entrance to the restaurant is around to the left, on the north side of the building. Please let me know if you are having dinner here so I can warn them how many people to expect.
Please keep in mind that it takes a while to get out of the circle. Google Maps says that from the Sycamore Canyon trailhead to Amado is 1 hour 11 minutes.

Below is an image saved from Google Earth showing the circle and areas. Clicking on the map will open a browser window with a larger image.
If you have Google Earth on your computer, I've also saved a KMZ file on my Google sites webpage, which you can download by clicking HERE. Google Earth is a program you have to install on your computer, and it's an amazing resource. You download the program to your computer from the Internet – and it's free and safe. To read more about it and see if your computer is compatible, go to earth.google.com. Once you have it and download the KML file, you can zoom into your area, tilt the angle, and move over the landscape with three-dimensional effects that make it appear that you're flying over the land. It's a fantastic way to study the topography of your area.
A Google Maps version (for which you just need a web browser, like Firefox) can be found by clicking on the map below.
This is an example of one of the maps I created using the 7.5-minute USGS quadrangles.
