Is it the little things?

When this young Chipping Sparrow hopped up and looked right into the lens, I was thinking that it was the little things that really counted. His Dad had been attempting to get him to swallow seeds whole. Therefore instead of giving the seed a bit of a crack first with his beak, Dad had been poking whole seeds into this little guy's mouth. The seeds then proceeded to fall right back out onto the ground every time. Suddenly the fledgling, after yet another sequence of drops, hopped right over to the glass door, and stared into the lens as if to say---"And you're looking at...?" It was one of those little moments that are very nice.


Which got me thinking about "the little things". For instance, here we have Great Lobelia, Lobelia siphilitica. What makes it recognizable as one of the lobelias are little things-the lobes. It has two on top that stick up like ears and three on the bottom rather like a lip. Therefore it's a Lobelia--the little things.

I was then reminded once again about "the little things" when I failed to get a photo of the other leaves of this plant. A little thing that has kept me from being able to identify it.

Then there is what I think of as a lovely little thing, the way rain remains droplets on a Mourning Dove's back.

By the way, the Mourning Doves are flocking. Friend and Doorstep are now almost always seen with their three youngsters from this season. The youngest was shunned there for a little while as he insisted on continuing to crowd everyone in hope of handouts. Usually members of the dove family once they leave the nest must learn to eat immediately or else. There is very little regurgitative feeding once they become quite mobile. Well in this case, the adults would hop at him and then chase him out into the yard away from the group. He'd stand out there and watch and perhaps think about the matter and eventually he got the message. Now that he's developed manners and doesn't beg, he gets to hang out with everyone else.

Then as I was standing out in a rather wet day, thinking about the little things, suddenly the Gulls began to do it again. Exactly what "it" is I've yet to figure out.

Suddenly, usually in late afternoon, a large flock of Ring-billed Gulls,(I think, I haven't gotten a good look at an adult yet), perhaps 70 of them, will appear above the ball fields in the park circling and calling. I thought perhaps garbage collection? But, no, that's not it.

Then today I realized that the adult gulls seemed to be pressing the immatures to land on the tops of the field lights in a kind of herding action. If the young fly off again, they are then "herded back on". ??? Interesting.

5:21:83 PM So out came the magnification.

5:22:04PM A group of five immatures, all pointing in the same direction, with four actually looking in the same direction. There is still a certain amount of herding going on with other lighting pole perches.

5:22:20 PM The gull cries continue. Adults swoop and circle. Number four is still looking my way, while two and three are thinking about where the other stands in the pecking order.

5:22:48PM I notice the Gull calls have almost completely stopped. One through Five are all looking fixedly at something. Unfortunately I can't tell what it is but I'm getting the feeling that what I'm seeing is some kind of youth training session. The adults are doing something that they insist the youngsters see.

5:22:57 PM One and Three are having attention span problems but Two, Four, and Five are still watching whatever it is.

5:23:05 PM Then everyone recovers their focus until Two loses hers. (Sorry about the raindrop on the lens.) Two is watching one of the adults fly off. The Gull cries begin again, the adults begin to wheel and disperse.

5:23:31 PM One takes off after an adult and within seconds all the others do as well. Now here's a case where I was watching the little things and whatever the big thing was got away. Though perhaps if I hadn't been watching the little things I might never have known that the big thing existed.

Next time: The Big Thing.

Just what were the adults attempting to have the immatures see and possibly emulate? Whatever it was it didn't take long. At least not nearly as long as a training session for a young Red-tail. A good thing too, as these immatures haven't nearly the attention span of a young hawk in training. But then again, being flocking birds, perhaps they don't need to have a long attention span. And in fact being gulls perhaps a long attention span isn't even a good thing considering their foraging habits.

Not an Urban Red-tail

Driving on Highway 59, I always look for him, particularly towards evening when he tends to sit on the lines to watch for rodents. And today there he was, foot up, relaxed, scoping the edge of the prairie created by the Tall Grass Restoration Project. I decide to try him again.

You see I'm okay 100 yards away. The truck is okay 100 yards away--but the photography equipment is definitely not okay.

8:28PM There he is. I do a quick turn around and then trundle down the opposite side of the road on the verge. He doesn't care. He's still watching the prairie edge. I get out of the truck, still okay, I poke the camera rode the truck's cap, he's still ignoring me. Unfortunately from this angle there's a big wire in front of him. I edge a bit further out, put my eye to the camera--no hawk. He's leisurely flapping off towards the oaks and disappears into the trees.

8:30PM See him? There he is--five acres away in an old oak.

8:31PM Preening. Completely relaxed, just far, far, away.

Now he's watching the edge of the soybean field for dinner.

He watches a Crow cruise by, looks down, goes into a swoop, and crashes through the soybeans. Then he's up with something in his talons and truly disappears into the trees this time. A country hawk who protects his privacy and doesn't choose to include us as part of it. I miss that inclusion here, spoiled by hawks that see us as no more than part of their usual landscape.

Time to go anyway, the clouds have gone orange.

And the sun over the adjacent trees has gone purple over the prairie. The cars speed by going 70MPH, without a pause. too used to having all this to even notice it.

Ground Squirrels vs Rattlesnakes, a Hell Bug Update, and Safe Parrots

This is what a California Ground Squirrel does when she sees a Northern Pacific Rattlesnake.

The noticeable move is a bushing of her Chipmunk-like tail and a flagging move. The tail remains upright while "flagging" back and forth to left and right.

A large part of the diet of Northern Pacific Rattlesnakes and Gopher Snakes is Ground Squirrel pups so everyone always feels sorry for the poor squirrel because how could she possibly win a confrontation with a snake. Particularly a rattler?

Well, it turns out that the squirrel, not only has defensive moves such as throwing dirt at the snake, or in a pinch biting it, she also has a secret weapon. One that belongs in the nothing-stranger-than-nature category.

When a CA Ground Squirrel runs across a rattler, not only does her tail flag, but new research finds that her tail heats up far above normal. Her tail heats up? That's right. And it works. Rattlesnakes have heat sensors and being an ambush hunter they will become defensive if a tail just flags at them. They've been busted and therefore their chances of surprising prey and hunting success is drastically lowered. But if the flagging tail sends a waving infra red signal the rattler becomes super defensive and will take off.

And besides that, the Squirrel only heats up her tail when a rattler appears. If the other predator snake of Ground Squirrel young appears, the Gopher Snake, only flagging occurs.

That is remarkably specific. Good old adaptive evolution strikes again.

And hey, how do they know for sure with multiple modulations that the rattlesnake's change in behavior is being caused by the super heated tail anyway.

You can't just run up during a squirrel vs rattlesnake confrontation and clip a thermometer to the squirrel's tail to check on whether it's hot or not. Neither the snake nor the squirrel is going to continue normal behavior even if you could convince the squirrel to stand still long enough to have her tail temp taken. Which they must have done at some point in order to know that the Squirrel tail gets hot in the first place, but poof goes the rest of the confrontation every time.

The Answer: They created Squirrel robots whose tails would flag and heat up with the push of a button. Therefore the different reaction of the snake to heated and non-heated flagging tails could be monitored.

I like that a lot.

Then we get to the Bugs from Hell, who I don't like a lot. This morning the vegetation above was a perfectly lovely squash blossom, by afternoon it had turned into something that tends to make me itch when I look at it. A Bugs from Hell Nursery.

(They've now begun to land in mass on my laundry when I hang it outside. I've begun to think of how one would feel when a cloud of locusts appears.)

Remember how I was going to make a Sage spray and try that as a repellent? Well the Daddy Long Legs knew something I didn't when he was laying in wait on the Sage. I went out today and the B from H's had started on the Sage.

Karen Anne Kolling emailed and suggested making some Red Pepper spray. So that's on tomorrow's menu. That is if there is anything much left to spray it on. You can see how locust thoughts might come to the fore.

And Good News passed along by Peggy M--Brooklyn Parrots reports that the Dustbowl Parrots--( nickname of the Leif Ericson Park ball field) survived the recent tornado.
