The chickadee calling in your yard right now may be telling you something specific, if you know how to listen.
Black-capped chickadees use two distinct alarm signals. A soft, high-pitched "seet" indicates a predator flying overhead. The louder, familiar "chick-a-dee-dee-dee" is their alarm, used when a predator is perched or stationary, and it contains encoded information that researchers at the University of Montana decoded in a 2005 paper in Science.
The number of "dee" notes at the end of the call corresponds to the threat level of the predator, and the relationship is counterintuitive. More "dees" doesn't mean a bigger predator. It means a more dangerous one, which for a chickadee is usually a smaller, more maneuverable one.
Think of this way: a great horned owl is enormous but slow and unlikely to catch an agile small bird. A northern pygmy owl, barely larger than a sparrow, is quick enough to actually succeed.
The pygmy owl gets more "dees." In the research recordings, a pygmy owl could generate up to 23 "dee" notes. A great horned owl might get two.
The flock uses this information. When the recordings were played back through speakers, the chickadees' mobbing response, the dive-bombing and harassment behavior they use to drive off predators, scaled with the number of "dees" in the alarm. More "dees," more aggressive response.
And it's not just chickadees listening. A 2007 study in PNAS documented that red-breasted nuthatches eavesdrop on chickadee alarm calls and respond appropriately to the encoded threat level, adjusting their own behavior based on information they haven't gathered themselves.
Every "dee" is a data point if you know what to listen for.
Gratitude to the universe and to all friends everywhere for so many kind wishes. My cardiac surgery went well -- better than expected. I'll update properly next week. Meanwhile, I'm home, surrounded by love, am enjoying a great reawakening of energy and intend to dive into writing Chapter 21 of my new book tomorrow. Happy Summer Solstice!

Rascal is still out there and radios in when he can, or when he decides to, rather 😉. This week he thought a handy @ShadowSysUSA in tiger stripe my do the trick. Sometimes you have to wander back into town to resupply camp and you don't always need a big bore. Thanks, as always, to @SummRidge for helping foot the bill for this week's piece!

I wish each and everyone of you the best of luck and thank you all for helping us spread the word of our small family business!
@advancedstats23@AdamAkbani That’s what I understand about his defense, too. But I wonder what a 75 or 80 should look like. Seems like scouts have capped their 20-80 system on both ends. Everybody is at least a 30 and at most a 65-70.
Rascal has been on the trail as of late. He radioed in just now that he recently broke the tree line only to find that infamous nature photographer and debonair man of adventure @actionxander ! Rascal gave a few pointers and wished him good luck finding those last three elusive Floridian quarry!
I am sure we can expect to see those three captured in frame before the adventure ends. We would love to see your favorite @actionxander photos pasted in the comments or used in your QUOTE POSTS, he does amazing work and is exuding that adventurous American spirit we need to resurrect and maintain so badly.
Rascal did say he has made great use in the field with his Ruger American Gen2 Scout rifle! Thus it has been chosen for this weeks win!
We are ever grateful for @SummRidge continued support! Thank you guys!!!

The box turtle in the road this month is likely a pregnant female on her way to lay eggs. Slow your roll on country roads, especially after rain.
Eastern box turtles nest from late May through early July. Females leave the forest to find dry, open ground for their nests, traveling up to a mile from their home range in the process. They look for fields, woodland clearings, gardens, lawns, mulch piles, and roadsides.
Most road-killed box turtles every year are nesting females.
If you see one on the road and it's safe to stop: move her in the direction she was already heading. She has a destination she's been traveling toward, sometimes for over an hour.
Don't take her home or relocate her elsewhere. Box turtles have a tiny home range they know intimately, and a relocated turtle will spend the rest of its life trying to walk back, usually dying before it gets there.
If you see her digging in a soft patch of soil at the edge of a road, leave her alone. She'll finish in 30 minutes to an hour and return to the woods on her own.
