Birdie Cam

Security web-cam in a bird house

We got a green-backyard.com WIFI web cam a few months back, built a house to suit our local black-capped chickadees, wired it up, and after a bit of time and some bird activity, we now spied an egg!

The house is based on a few plans on the internet and had to have a tall, accessible, attic and a window to let in a bit of light. It seems the birds don’t mind if there is an frosted window.

Tall wooden birdhouse with a hinged roof and camera, plus a hinged front for cleaning. Also a small frosted plastic window to one side.

I chose some scrap wood that was lying around to make a cheap first try. I was also thinking the older wood may make the birds feel more “at home”. You can see how the plans have the roof hinge up to access the camera for installation and maintenance. The front opens up to allow for easy cleaning.

Brown, long, birdhouse on the side of a 4x4 pole with gray metal cylinder below.

The house was bolted to a 4″x4″ pole, that can easily be removed, about 7′ up. I also wrapped a piece of sheet metal to serve as a squirrel baffle.

This camera had to be within range of our household WIFI as well as an extension cord from an outside outlet. You can see the wire running out of the bottom of the squirrel baffle.

The whole thing gives off a bit of a steam-punk vibe, mostly because I used a scrap piece of copper to protect the entry from predators enlarging the hole.

The included software is basically an ad supported security camera app/program, and while it could be configured to stream, we have just been piping it over to the TV and seem to have it on in the background a few hours during the day.

It’s been pretty interesting to watch the birds go about their day – watching them place moss and wonder about the other materials in the nest. We worry when they go away and leave the egg alone. It is comforting in the early morning to see what we think is the male coming in and standing guard at the front entry hole. (Usually there is only one bird in the house at a time.)

6/2/2022 Update.

We now have seven eggs. One bird is usually nesting, but will leave for short periods.

6/3/2022 Update.

This morning we had our first chick. As of this writing, five of the seven eggs have hatched. Adult birds (mom?) is busy going in and out with small insects and spends some time sitting in the nest. They also eat the shells. (I’ve heard to make up for the loss of calcium.)

The nest had seven eggs total. One never hatched, but the others did. Unfortunately, two of the fledglings did not survive. The birds started growing fast, getting feathers and eating constantly. Recently, we had a bit of a heat wave and the sun hits the house directly. The birds were huddled up next to the corners to catch any sort of draft from the cracks in the walls. We ended up hosing the house down with water then fashioning some shade.

6/21/2022 Update:

All too soon the first fledgling left the house. We had noticed they were no longer staying in the nest, but liked to perch by the ‘window’. One morning they hung out by the door for awhile, and then the were gone –

6/22/2022 Update:

The last of the three fledglings left today. We read that they do not go back to the nest, but hang around on local branches still being fed by their parents. So curiosity got the best of us, and we decided to take a look.

The single egg that didn’t hatch was still there. We have no idea what happened to the hatchlings that didn’t make it.

Social experiments, fine art, and r/place

r/place

Over the weekend, Reddit put up their annual place collaboration area. They allow one to place a single tile every five minutes on a limited size canvas. There are hundred of thousands of people doing the same. Thus, there is not enough time to create much by oneself, and one runs the risk of one’s tile being overwritten by others. It ends up being a fascinating event of collaboration.

My humble addition is the attempt to help in the creation and defense of “Nightwatch” by Rembrandt that was organized in the comments section of r/place on Reddit.

Pipe Straw

1" diameter straw made jutting out of a foamy green smoothy.
It’s a mouthful.

Having appreciated the large straws furnished by boba tea places, I decided to go wider. Cut, shaped, sanded, and cleaned a 1″ O.D. ‘PVC’ pipe (suitable for potable water). Definitely more of a pipe than a straw.

It’s a bit like drinking from a firehose.

Oregon Health Cartogram – Depression by County

(Update Nov 28: Added disclaimer about population health veracity. This graph really is based on the OHA documents, but it has not been vetted by health experts.)

My second run with the Oregon cartogram I’ve been developing with some actual data.

I chose depression because the OHA had more counties represented in it’s chronic diseases report. Unlike my earlier Oregon cardio diseases cartogram, I was curious to see just one disease category.

Preliminary thoughts,

I like the bold, single category bar graph. It fills each block nicely. I can see how the small multiple needs to span enough space so that the overall table retains the shape of the state. I rather roughly tweaked the original bar graph images to get a better look; you can see how that caused Clatsop to be a little wonky – I wanted the numbers not to be too squished. More time could be spent to make this more refined.

It is interesting how one can run along from North to South or East to West to see how there may or may not be any trends. Much easier with the single data category.

I liked the idea of a placing an average line for quick comparison. However, the line is based on the averages of the counties percentages, and not the individual counts within. Thus, it is somewhat problematic. With proper math, I think this brings an important overall dimension to the data. Also, I find myself relying on that line to compare charts and I lose track of the actual percentage. Perhaps all small multiples should have their y-coordinates shown

I may change the “NA” image to fill the same space as the small multiple. I think that will help those areas maintain their location and help the overall shape of the cartogram.

Oregon Health Cartogram – Chronic Cardiac Diseases by County

This is my first chance to try out the Oregon cartogram I’ve been developing with some actual data.

(Update Nov 28: Added disclaimer about population health veracity. This graph really is based on the OHA documents, but it has not been vetted by health experts.)

(Update Nov 27: I was too focused on the data when I uploaded this and not on the overall cartogram itself. I like the way the data relates to others geographically close to it, which is kind of the point, but nice to see it in action. You can easily compare the coast to in-lands, the Portland metro area to elsewhere, North to South, etc… Those blank areas where their are not counties shown are disconcerting even when you know Oregon. Hard to tighten it up, ‘tho. Also counties with no data, marked “NA” is odd. The OHA has some similar data on depression with more counties, but only one category; that sounds interesting, so a depression cartogram is up next. )

Some things I’ve learned so far,

How does one handle possibly unreliable data? Cite it. Looking at this graph now, I should go back and maybe add and note which counties the OHA said were unreliable. I did not to distract with a footnote, but there may be a clean way to note it. It would fill the graph better.

What to do with no data? Nothing is better than null. I placed a light “NA” graphic to fill the space, but not compete with the data I had.

Graphic image or coded block? Go with your strengths. Despite a few hours of trying, I could not work with WordPress to make an html table graph on the page format properly. I really wanted the possible interactivity options and the abilty to quickly swap out new small graphs for different topics. I ended up taking a screen shot of my code in the browser and called it good. Not ideal, but this allowed me to get something up. As an aside, I wanted to use SVG’s for the bar graphs so I wouldn’t have to deal with images and files. That will take more skill development, and time.

I wonder if radar graphs would have been a better choice to compare small multiples. One worry I had is that some categories did not have any data, and I thought the radar chart may not show that easily. (I used Google Sheets pivot charts to make a large bar graph which I then split up with GIMP. I didn’t see how to easily do a bunch of radar charts.)

More thoughts from me perhaps later. I’m always interested in constructive criticism.
