Friday, February 20…Faces of Stone (David Gilmour)

   It seems as soon as the sky lightens with the rising sun, the birds come alive, whether they can see the sun or not. Their chatter woke me this morning; I pulled the shade aside to see if the sun had popped over Newman’s Peak, which is to the east of us. It hadn’t; but it wasn’t night dark and it wasn’t daylight over on this side either. Sort of like dusk but in the morning.

   I was curious about why the birds were chirping before the sun was officially up over the mountain, so I googled “Do birds wake up at sunrise?”  I found mention of the ‘dawn chorus’, a phenomenon that usually takes place before sunrise, on several sites. I went down that rabbit hole for a few minutes.  Woodlandtrust.org.uk had the most concise explanation:

What is the dawn chorus?
Simply put, the dawn chorus is the collective twitterings, tweetings and chirps of wild birds. The sound is unmistakable. It starts with a few songs – listen for robins, blackbirds and thrushes – just before dawn. They’re soon joined by other voices until all the birds in the area are singing together.
Why do birds sing in the morning?
The dawn chorus is all about defending territory and raising chicks. The singing you can hear in the morning is typically carried out by male birds. Making so much noise uses up a lot of energy, especially on an empty stomach and after a chilly night, so only the strongest, best-fed males will produce the loudest songs. In doing so, they demonstrate to females that they are fit, healthy and hold a territory with plenty of food. A loud song also serves as a deterrent for any rival males who may be looking to move in.
Why do birds sing so early?
Early mornings are too dark to search for food, and too dark to be spotted by predators. That makes it the perfect time to sing. As there is less background noise and the air is so still, sound carries around 20 times further than it would later in the day.

The site reconnectwithnature.org had this to say about quality of song in the early morning vs. later in the day.

   Researchers at one time believed birds were also taking advantage of the cooler, drier air in the morning to allow their notes to carry a little farther, but research has shown that's not the case. Their notes actually carry as far — or even farther — at midday than in the predawn hours thanks to their early-morning warmup, according to a study conducted by a team of researchers at Duke University.

   The Duke researchers hypothesized that songbirds' early morning concert is a warmup so they can perform vocally later in the day, and they tested their theory by studying the behavior of a group of male swamp sparrows between 2 a.m. and noon for two to three mornings per bird. In all, they analyzed more than 1,500 swamp sparrow songs, and they found that the birds' vocal ability improves as the day goes on, allowing them to sing more complicated notes and songs as the day progresses. While the study demonstrated a clear improvement in singing ability after the birds' early-morning warmup, researchers aren't certain what causes their singing to improve.”

Well, I know that my “just out of bed” voice doesn’t sound like my “I’ve been up and talking for an hour” voice. Not hard to imagine it’d be the same with the birds. But doing a study on it? 🤔

   The sun coming up over Newman’s Peak sure wasn’t much of a day brightener. Cool, cloudy and looking like rain at 8 a.m., but by 11 o’clock, the dreariness had moved on, and the sun was shining bright. With the shades open, the sun made my ‘office’ comfy cozy warm. However, a sweatshirt or light jacket was needed when going outside because of a coolish breeze. Remained like that the rest of the day.

   Our bird feeder camera worked great at home on the back deck but couldn’t make it work yesterday. Started troubleshooting the problem while waiting for the laundry to finish. Then we spent way too much time beyond that trying to get it to talk to a nearby network. Joe’s satellite and the camp’s Wi-fi both put out too much signal, I guess. It needed 2.4 GHz only and both of those were 5 GHz. Picky!! We changed our mobile hotspot to 2.4 and still couldn’t connect. And to check an important detail, it indicates I go to a feature in the app that isn’t in the app. Agh! So frustrating!  Finally decided to come back to it later. Came back to it four hours later…Nope, still just as frustrating. Fiddled with it a bit more and finally put it back in the box. I’ll make a phone call to customer support on a yucky rainy day when I can’t be outside. Or maybe just wait until we get home.

   I woke up still dealing with a stuffy head and runny nose. Not so much sneezing today, though. Kim wondered if it was really the result of the windy ride or if I came down with a cold. Nope, I’m convinced this is because the wind was blasting through, up, and around my sinus cavities. Time to do another Google search. This is an AI answer to my question “What happens when extreme wind blows through a sinus cavity”:

   Extreme wind blowing through a sinus cavity—or more accurately, passing over the nasal passages—typically causes intense drying of the mucous membranes, irritation, and inflammation. This results in severe congestion, facial pressure, headaches, and in extreme, rare cases, barosinusitis (pressure damage).

Dehydration of Membranes: Strong, dry winds strip moisture from the nasal passages, causing the delicate membranes to become irritated, inflamed, and swollen.

Increased Irritant Exposure: Winds, particularly in desert or dry areas, carry high amounts of dust, pollen, and pollutants, which get trapped in the sinuses and trigger excessive mucus production.

That’s good enough for me.

   Drove out to the petroglyphs out on State Land to play with the drone. More accurately, Kim playedwith the drone, and I sat on a rock taking pictures of petroglyphs I was sure I hadn’t seen before (but really, who knows?) and then of faces I saw in the rock formations to send to eight-year-old Shelby. There was a sleepy turtle, a fish, a sleeping kitten, and a rare head shot of a smiling T-Rex. That last one owes its inclusion to a strategically placed petroglyph above a curved crack in the rock.

When all the playing was done, we walked around the mountain. The sunny, yet cool day was perfect for a leisurely walk through the desert. Heard a bird singing now and then but otherwise it was quiet. So different from the bird chatter we’re used to hearing at the campground. Hard to imagine a raucous dawn chorus taking place out there, more like a solo version.

   Stopped at the IGA today…two bags of piggy cookies still on the shelf.  Not ashamed to say I bought both. It works good to freeze them individually in plastic wrap, then thaw one out in the sunshine when the urge to eat a piggy cookie comes over me. The sun warms it and the condensation from the wrap moistens it, making it taste fresh out of the oven. Perfection!
