Eyes Upon Me

Ever get the feeling that someone or something is watching you? For some folks this is a spooky feeling to get while traipsing around in remote areas, but it's a good thing if you are looking for owls like I was on the Bonny Christmas Bird Count held last weekend in Eastern Colorado. Long-eared Owls like dense roosts in junipers, Russian Olives, etc. and this spot didn't disappoint.

iBird Explorer for iPhone

I gave myself a fantastic little toy a couple of months ago for my 40th birthday- an iPhone. The multiple communication, navigation, and web features (built-in and 3rd-party apps) already make it an incredible birding tool, but bird-specific applications for the iPhone have seemed to be conspicuously absent until the last month or so.That's not the case anymore! I just got a review copy of iBird Explorer in the Backyard and Plus versions for iPhone- their simplest and most inclusive, respectively (iBird Explorer also comes in a Windows Mobile version.) iBird Explorer Backyard has 145 species and is marketed at casual birders, while Plus covers 891 bird species for us serious folks. iBird also comes in several regional packages- West, Midwest, North, South, and Canada. I'll profile it a bit more in my next Geared for Birding column in Winging It (The American Birding Association's newsletter), but at a quick glance this is a very cool app. Here's what their features page lists, with a few of my comments:
  • ■ Plays the songs and calls of almost any species of bird in North America. And it’s loud enough to attract the bird right to you! (Use responsibly! To their credit, iBird Explorer's web site includes the ABA Code of Birding Ethics.)

    ■ A visual icon-driven search engine for identifying species by color, shape, habitat, location, etc. (Cool concept- haven't tested it much yet, though.)

    ■ Hand-drawn James Audubon quality full-sized color illustrations with both perching and flight views (Well, John James wouldn't be my first choice of comparison, but we get the idea...)

    ■ Multiple professional photographs of every species in numerous plumages, sexes and seasons (Nice idea, and an area that should grow in future releases. Will this end the age-old arguments of illustrations vs. photos in a field guide?)

    ■ Identification and behavior information so extensive it covers everything from what the bird eats to the color of the eggs it lays (A little Birds of North America-style info- always good. Speaking of which, how about a BNA app??)

    ■ Full color range maps for every species (Did Paul Lehman have a hand in these, too?)

    ■ Detailed Wiki pages for every bird (Welcome to Web 2.0!)

    ■ Lifetime updates (you never need to buy another guide because we push out any changes we make for free) (Could be the single best feature of guides like this vs. paper books.)

Other planned upgrade features:
  • ■ Additional illustrations covering other plumages including seasonal, fledgling, juvenile, etc. (The more the merrier. Wonder if Sibley &/or Kaufman are thinking about this format?)

    ■ Many new photographs. (Can you ever have enough?)

    ■ Sighting/Observation list feature based on You’ll be able to record all the details of any observation or sighting then upload it to the popular eBird database where you can have your own account. (I think this is a must-have feature on any web-enabled smart phone or Windows Mobile device!)

    ■ Synchronization with user accounts. (Don't know what this is but I'm sure users will be happy.)

    ■ Quizzes and identification tests, puzzles and word games. (I'm all for anything that might engage kids more or make road trips a little less boring.)

More generally, this type of bird guide (along with Windows Mobile apps like National Geographic Handheld Birds and Pocket Bird Recorder) offers extreme portability, the ability to integrate multimedia like sound files (can video showing behavior traits be far away?) and checklisting capabilities. (Like how I made a verb out of checklist? Maybe I should trademark that if someone hasn't already done that...) I have a feeling that more iPhone birding apps will debut in 2009- is the era of guidebook 2.0 getting into full swing?

Google Mapping a CBC Circle

I've previously posted about how to use Google Earth to plot out a Christmas Bird Count circle (mainly riding on the coattails of Bootstrap Analysis)- a great way to virtually scout and see count territory boundaries, etc.

Recently, I had correspondence from Chris Hill who decided to use Google Maps to set up his count circle territories, citing the ease of sharing the maps and for the potential of letting others add to the map, too. The only hitch seemed to be getting a good 7.5-mile radius circle drawn- Google Maps has line & polygon tools but not a circle generator. Curious, I did a search and it turns out that you can import a .KMZ file that Google Earth generates into Google Maps- easy directions are posted on the Google Lat Long blog. Ba-boom- the best of both worlds. You can work up your circle &/or territories in Google Earth, import it into Google Maps, and then share the URL with whomever. You can even embed the Google Map in your blog or other web page- see below.

Basically, here are the steps, summarized from Bootstrap Analysis and then adding the step of importing the .KMZ file into Google Maps. First, you've got to get the Lat/Long coordinates of the count circle center. You can get this by hovering your pointer over the spot in Google Earth and noting the coordinates, or you can get the coordinates that are on record with Audubon through the compiler's page (although many of these aren't too accurate, having been estimated from paper maps, often not at very good resolution. National Audobon is requesting updated count center coordinates and descriptions-see here.)

If your Lat/Long is in minutes/seconds then you will need to convert them to decimal- easily done here. (Note that if you acquire the coordinates from Google Earth they will already be decimal if you set that format in the preferences- also the default setting, I think.)

Then you link to the free KML Circle Generator, plug in your center coordinates, and set the radius to 12,070.08 meters (the equivalent of 7.5 miles.) This will return a link that you follow to download a .KML file which will open in Google Earth as a nice circle demarking your count boundary. Right-clicking on it and selecting "Properties" (or "Get Info" on a Mac) will let you re-name it, change the color, change the thickness, change the opacity, etc. Then, if you want, you can use the line, polygon, and placemark tools to further divide and/or organize your circle. I also put a placemark at the count center. Now you've got a collection of map elements that you can save as a .KMZ file by right clicking on the folder and choosing that option.

Finally, go to Google Maps and choose the "my maps" option. Select "create new map", and give it a name. Right above the name there are two links- "collaborate" and "import". Choose the import option and find your .KMZ file wherever you saved it. Google Maps will pull the circle and whatever else you created in Google Earth to your new custom online map. You can further edit it in Google Maps with the line tool, polygon tool, placemarks, etc. I haven't explored the feature much, but using the "collaborate" link lets you give editing privileges to others. Once your map is ready and saved, you can use the print, send, and/or link options to share it with others.

Anyway, another great, free way to share and collaborate with your fellow counters or other organized birding tasks requiring maps. Lots of CBCs still to come- good luck & have fun out there! Update: I've got all of the Boulder CBC territories on my Google Map but they don't all show up on the little embedded version- click on it to get to the bigger version with all territories, navigable between pages 1 & 2 of the map. ;-)

Cold Count

The 67th Boulder Christmas Bird Count was held last Sunday, which also happened to be the coldest day of the season so far (with record-setting cold later that night!) I compile the count and was a nervous wreck worrying that we'd get shut down by the weather. The count is traditionally scheduled for the first Sunday of the count period (Dec. 14 - Jan 5) and with 30 territory leaders and usually over 100 participants, the show almost has to go on- there is simply too much inertia once everything is in place to just decide to postpone for a day or even a week (barring, I suppose, the storm of the century or something.) So out we all went, with 4-5 inches of fresh snow and temperatures a few degrees either side of 0. This Townsend's Solitaire kind of sums up the feeling of the day- cold, snowy, but beautiful.
My team of hardy birders (below, from left: Yours Truly, Connie Kogler, Dave Alcock, Mike Freiberg, and Dan Maynard) went up in the Boulder foothills to an open space park called Betasso Preserve. Our second bird of the day also turned out to be our best- a very chilly Brown Thrasher subsisting on Russian Olive berries bordering a horse corral. Beyond that the birding was kind of slow but we had some nice montane species and it was priceless to walk a 3-mile loop in a typically busy mountain park with the only tracks before us in the snow belonging to deer, squirrels, and rabbits.
Once we wrapped up in the mountains, we descended to warm up, re-group, and get a bite to eat at The Original Pancake House in Boulder. The host took pity on us and produced a huge complimentary apple pancake to nosh on while waiting for the rest of our orders.
Re-stoked and warmed up, a few of us headed back out to surmount the mesa in the midst of the Valmont Reservoir complex, lakes warmed by a power plant nearby and often chock-full of great birds. Divers like Double-crested Cormorant and Western Grebe overwinter here in small numbers, the only location in the count circle for such species that would normally depart for warmer climes. Unfortunately, the combination of relatively warm water and very cold air (about -5 F by then) produced very foggy conditions. Still, we gave it a go, sometimes glimpsing birds through quick gaps in the fog like a raft of about 75 Red-breasted Mergansers. Earlier in the day, a team had covered the territory from inside the fenced complex (permission and chaperone required from Xcel Energy) but had missed seeing any of the Western Grebes that should have been out in the fog. Fortunately, from our higher vantage we could hear at least one give its kree-kreeee call- tick it!
I'd like to thank everyone who braved the cold to participate in the Boulder CBC. We were able to add one new species to the all-time list (bringing it to 206) with a Great Black-backed Gull, and other highlights included Western Bluebird & the aforementioned Brown Thrasher (each the 11th time on count day), Lesser Goldfinch (9th time), Eared Grebe & Hermit Thrush (each for the 5th time), Lesser Black-backed Gull (4th time), and Brown-capped Rosy-Finch (3rd time, complimenting Gray-crowned's 14th appearance.) Next year will be the 100th aniversary of the Boulder count, which was first run on Dec. 24, 1909. It's going to be big so make plans to join us on December 20, 2009! Meanwhile, there's plenty of time to join another count this year- you can find one on Audubon's Find a Count Circle page.

Detective Work

Back in October when I visited the Bay Area in California I was tickled to get some nice photo opportunities featuring Golden-crowned Sparrows. I don't get many chances at these (they rarely vagrate into Colorado) so seeing them and hearing their vocalizations was very cool. One that was perching cooperatively at the Palo Alto Baylands sported a band- sweet! As I was editing the pictures I realized that I could make out lots of numbers, so I enlisted the help of some bander friends of mine who knew their way around banding codes. From the various angles, they figured out that only the first number of each sequence was missing (?###-?####). With that information, there was a chance of figuring out the exact number (for example, the first number in the prefix was likely a 0, 1, or 2 based on the band size that Golden-crowned Sparrows take, and from that sequence, perhaps only one of the used band numbers in the 5-digit suffix was from a Golden-crowned Sparrow.) From there I chatted with a very helpful person at the USGS Patuxent Wildlife Research Center Bird Banding Lab (the national clearinghouse for bird banding information), who couldn't come up with a match at the time but promised to look into it. Look into it she did, and I got an email today that they were able to nail down the band number and the information on the bird, which I then formally submitted on the band reporting site. Turns out the bird was banded on 15 April 2008 within a few hundred meters of where I saw it on 10 October 2008. In the intervening months it migrated north, as Golden-crowned Sparrows breed near treeline in Brittish Columbia, Yukon, and Alaska. Then it came back again to its wintering territory at sea level on the southern San Fransisco Bay area- nice round trip and very tight site fidelity!

Welcome Back!

I was tickled to hear from a friend that the light-morph Harlan's Hawk (harlani subspecies of Red-tailed Hawk) I found last year was back again on the same winter territory. I had looked along the row of power poles where I saw it last winter a few times without success, but yesterday I packed up my camera and good luck charm (my son Garrett) and we took the road less traveled on our way to do a few errands, cruising the strip south of Hygiene, Colorado, to see if the bird was there. Sure enough, it was on practically the same power pole as last year! When I snapped it last time, it was eating something, allowing me to get pretty close for posed pics but I never got anything good in the way of flight shot. This time it was kind of flighty, only allowing moderate-distance posed pics. But much to my delight, instead of flying away it flew along right past me. It wanted to stay on the power poles next to the road (probably waiting on rodents in the grassy strip between the road and a field beyond), and would shift three or four poles south each time it flew, allowing me to repeat the photo opportunity several times (I stayed in the car and shot from the shoulder of the road.) Not only that, but the magic combination of sunshine and snow on the ground really lit up the bird nicely. Rare bird, flying close by, in about perfect light- priceless! In my last post about the bird, my buddy Jeff Bouton said he hoped for continued reports and more images. Here you go, amigo- better late then never!
