Atascosa Highlands CBC December 19th, 2017

Last season's CBC led the nation in number of Montezuma Quail with 271!

This season's Atascosa Highlands Christmas Bird Count will be held on December 19th, 2017. If you're available to help with the Atascosa Highlands count please email Jake Mohlmann (mohlmann2 AT yahoo.com) to sign-up!

Last year this CBC led the nation with the highest tallies for 16 species and 2 forms. These are listed below:

Montezuma Quail - 271
Whiskered Screech Owl - 2 (tied with Patagonia)
Common Poorwill - 2
Elegant Trogon - 7
Red-naped Sapsucker - 84
Gray Flycatcher - 103
Dusky Flycatcher - 11
Western Flycatcher - 2 (tied with Sedona)
Mexican Jay - 359
Rock Wren - 161
Canyon Wren - 164
Bewick's Wren - 372
Painted Redstart - 12
Chipping Sparrow - 3169!
Dark-eyed Junco (Gray-headed) - 232
Canyon Towhee - 248
Rufous-crowned Sparrow - 307
Hepatic Tanager - 23

One national high count was obliterated last year when 103 Gray Flycatchers were recorded, blowing away the old record of 68 reported by Nogales during 1977. Needless to say this is a very special Christmas Bird Count and I hope you can help.

See you out there!

Atascosa Highlands CBC countdown dinner 12/19/17

CBC Participants -

The countdown dinner is often the most exciting part of the day!  Teams will each have a chance to tell of exciting events that happened as well as any notable bird sightings. Having a warm place with good food is crucial to this end of the day activity which is why I am happy to announce that Wisdom's Cafe has again graciously offered to host our count-off dinner this season! If you've never been here before I can highly recommend!  It's delicious authentic Mexican cuisine at its finest!

Check out their website for the menu.  http://www.wisdomscafe.com/

They are located 3 miles south of Tubac and 1500 feet north of the Tumacacori Mission, on the east side of the road. Take the Tumacacori/Carmen exit and head north on the east side frontage road. This exit is just 9 minutes south of the Amado Exit for those covering the west side of the circle and escaping via Arivaca Road rather than the Ruby Road exit on I-19. Just look for the giant white Rooster!

The restaurant opens at 5:00p.m. so you can arrive anytime after that.  I will try my best to arrive by 6:00p.m. shortly after which I will begin the count-off.

cheers,

Hello Atascosa Highlanders,

I want to thank everyone who came out to cover the immense area contained within the Atascosa Highlands CBC circle.  True, we technically have the same number of square miles as every other CBC in the world, but most of ours doesn't have good road access!  So thanks for making the effort, no matter what section you surveyed.

Below is a copy/paste of the final numbers from Excel.  If this doesn't render properly in your browser, let me know and I can send it to you individually.  We tallied 131 species, which is on par for this count circle.  This year we had 68 observers, a pretty reasonable turnout for such a remote area.

The big news is that we added two species to the all-time list for the Atascosa Highlands CBC: Nutting's Flycatcher (in the Warsaw/Holden Canyon area) and Rufous-capped Warbler (Rock Corral Canyon)!  Congrats to the teams that picked up those unique species.  The Nutting's Flycatcher represents the 4th occurrence for the species in Arizona and is only the 6th record for the United States.  Not new for the count circle but very much noteworthy was a Least Grebe found on Bear Grass Tank.

We also set 11 records for all-time high counts within the CBC circle.  These species were: Common Merganser (35 individuals), Sharp-shinned Hawk (15), Sora (7), Great Horned Owl (21), Dusky Flycatcher (21), Eastern Phoebe (4), House Wren (53), Black-tailed Gnatcatcher (89), Black-capped Gnatcher (13?!), Common Yellowthroat (9), and Lincoln's Sparrow (293).  A special note on two of these: Rock Corral Canyon broke the record for Black-capped Gnatcatchers all on their own with 7 unique individual (previous high count for the entire circle was 3); and Arivaca Lake and Chimney Canyon broke the Lincoln's Sparrow high count all on their own (with 99 - previous high for the entire circle was 98!)

With some help from the primary compilers (Jake Mohlmann and Rich Hoyer), I hope to offer an assessment of how we did compared with the rest of the United States fairly soon.  Regardless, it's pretty neat to have a number of vagrant species from Mexico - including at least one that inspired some birders to buy plane tickets to Arizona.

Other species highlighted in yellow were noteworthy in my mind because they either came close to breaking the all-time high counts, or they're just rare within the circle or the region in general.  I'll let everyone peruse the list below, rather than summarizing that in another long paragraph.

Thanks again, and we hope to see everyone next year!  We'll try to get a date for the 2017-2018 season posted ASAP.

Good birding,
