I am moving my nature journaling over to iNaturalist. For now. :)

Spring flower

Trees and bees.

During my lunch hour I took a walk along the river. The trees that bear fruit that no animal seems to like were in full bloom. The white blossoms were fragrant. Each tree I looked at had at least a few bees buzzing about.

Date: April 27, 2015
Time: 1:12pm
Location: Steamboat Park
Temperature: around 65 °F
Wind: 17mph
Skies: altocirrus

Butterfly

I am Not sure what kind of butterfly this is. I think it may be a swallow tail. I saw two of them around this forsythia bush on Farm  Island.

Chorus Frogs

Date: April 11th 2015
Time: 7: 40 p.m.
Location: Farm Island causeway
Temperature: 80 degrees Fahrenheit
Wind: 20 miles per hour

The chorus frogs were really singing. I heard them about 2 weeks ago but they were not as loud as they were last night. Always a welcome sign of spring.
Since they stop singing when you get close it's hard to get a picture. So this picture is of the wetland near the Missouri River where you can hear them.

Budburst

Date: April 9, 2015
Time: 8:30 AM CDT
Location: South Dakota Discovery Center
Temperature: 40°F
Winds: ~20mph
Skies: nimbostratus.

Things are starting to bud out. I see redbuds in bloom when I take my lunch time constitutional. We have had some above normal temps with low precipitation in the weeks leading up this one. My hope is that the rain we are getting today will help things green up.

This photo is of a red osier dogwood by the South Dakota Discovery Center's butterfly garden. You can barely see the budburst but they are there. The bud on the bottom left is 1.5 cm long.

The red osier dogwood is a species of interest for Project Budburst, a phenology based citizen science project.  Look for the report on the Budburst map.

Farm Island

Date: Sunday March 22, 2015
Time: 12:00pm CDT
Location: Farm Island
Temperature: 45°F
Wind: ~15mph
Skies: altocumulus

I took a long walk on Farm Island on this early spring day. The cardinals were particularly active vocalizers. I saw or heard chickadees, nuthatches, juncos, flicker, a red wing blackbird, and many robins way at the end of the island. They are still in first wave formation, not spreading out to their territories yet.

I also came upon an unbeknownst to me wetland with hundreds of ducks. When I was approaching it, I heard what I thought at first were chorus frogs. Even though the sound wasn't quite right for a chorus frog, I didn't know what else it could be as it was obvious there were a lot of whatever it was. I finally got close enough to see through the brush to a good sized area full of all kinds of ducks.

I didn't have my binoculars so I couldn't get a good view but I saw coots among them.

I also saw an adult bald eagle.

The video offers some bird sounds (chickadees and cardinals) as well as a view of the terrain in early spring. I come back from these rambles with a lot of burrs and grass in my shoes and pants.

La Framboise Island

Birds are very active on La Framboise: Cardinals, robins, waxwings,  downy woodpeckers.

Date: March 14 2015
Time: 3:25pm
Temp: 70°
Wind: 15-20mph
Skies: altocumulus

This male robin was eating berries off the cedar tree.

Chicago

I'm in Chicago for GLOBE meetings. The walk between the hotel and the meeting room is about a mile, so I get a nice walk to and from each day. Even though I am walking along the Chicago River (a very developed and unnatural riparian area) I have yet to hear or see a robin.

I have seen sparrows, a crow and ducks, and I have heard a cardinal in the park across from where we are meeting but I have yet to see or hear a robin.

I hear it's in the 60's back in Pierre. I can only surmise that the robins are really active and I'm not there to see them.

(sigh)

Male Robin

Date: Thursday March 5, 2915
Time: 5:59pm CST
Location: South Dakota Discovery Center parking lot (James and Sioux Ave)
Temp: 44°F
Skies: Clear
Wind: 5mph

I heard a male robin yesterday. He was vocalizing the "peek and tut" call. As with most birding, I heard him before I saw him. We are in for a week of warmer weather so I anticipate that the robins will really be moving out. Unfortunately, I will be in Chicago. It will be interesting to see what they are doing there.

Virginia is for Robins

Date: Feb 26, 2015
Time: 1:10pm EST
Location: Hampton VA Coliseum
Temp: 32°F
Wind: ~18mph
Sky: Nimbostratus, snow

No pictures but I did see a flock of robins here in Virginia on my way into the quilt festival. Still no singing.

They were snowy and I have to imagine feeling a mite surly if robins can, indeed, feel surly. To my knowledge there is no research about surly robins but I can't help but think they want to be about the business of fighting for territory and singing to attract a mate.

The robinwatch campaign is going. These things always gain a small cult following so I will keep it up through the first day of spring.

#Robin Watch

After giving the matter some thought, I decided that for me, the best way to kick off a unit on robin's was to do so through the South Dakota Discovery Center's account on Twitter.

Yes, yes, Robins. Twitter.

I am getting the word out about #RobinWatch for the month between President's Day and the first day of spring, inviting people to tweet their robin sitings, sharing resources about robins.

Since I am in Virginia this week, I'll be limited to what I can share as me, the observer. But the robin tweets will go on.

Accepting the Robin Challenge

I will admit that I particularly liked my last week's post about kicking off robin studies in lieu of a Valentine's party.

I realized today I should do a bit more than tell you "Kick off a robin study" as if it only involved going to the local big box store and buying a box of robin studies that you pass out on Monday morning.

Part of this online nature journal is to be a model of one way to do nature journaling in an educational setting.

So join me as I accept my challenge to myself and attempt to keep a nature journal that includes robin studies.

A single male robin, sighted on my neighbor's deck. I saw him as I was returning back to the house after dragging out the recycling for pick up. He was outside when I went to check a few minutes later but gone after I left and returned with a camera.

No subsequent robins, no singing this week because it's been cold. I will be out of town next week and if it's warm, i.e. upper 30's, I expect the robins to start moving in and sing.

Also, this is a cautionary tale about not recording your data as soon as you collect it as I have no memory of Temps, Skies, or Wind.

Loud Geese

Date: Feb 14, 2014
Time: ~ 1pm
Location: Capitol Lake
Temperature: 10°F
Wind: 15-20 mph
Skies - stratus

I have mentioned before how Pierre is on the flyway for Canada geese. In the winter we get thousands of geese in town, a large number of which land on Capitol Lake, nestled between the Governor's mansion and the Capitol.

Canada geese by themselves or in small flocks are loud. In numbers this large, they are really loud. I don't know a word other than loud, but if there is one feel free to use it.

In this video you can hear the geese. You can also hear wind, and cars passing.

Preparing for Robins

I'm veering off from the straight nature journal into a bit of pedagogy.

Last night I participated in a Twitter chat with teachers and the question came up about plans to observe Valentine's Day. As a child I dreaded Valentine's Day because the mushy cards that we were required to send, the only type available, were met with "Ewww, yuck" from the boys upon seeing the card was from me.

Or at least, that's how I remember it.

Not wanting to inflict this same trauma on the next generation, I suggested that instead of a party, that Valentine's Day be the kick off for a unit on robins and spring. Why?

1. It was a medieval tradition that birds selected their mates on Valentine's Day and indeed, some birds species do start singing in February.
2. Robins have a red breast and red is the color of Valentines.
3. Robins will be on the move shortly at least here in South Dakota. Robins will start showing up and evidencing mating behavior within the next month.
4. They have the best Latin name: Turdus migratorius 
5. Robins are abundant, easily habituated to people and are widespread making them easy to monitor even for younger children.

Things you can do:

• Prepare to monitor the American Robin on Journey North. Learn identifications, behavior, songs, food. 
• Establish and identify monitoring points on school grounds that you will use to look for robins. Take a walk and familiarize students with them. Later on in the spring and even next year's students in the fall can revisit these sites and report out on robin activity. This is a great historical data set.
• Have a robin or bird party! Check Pinterest for ideas and turn your creative parents loose on the idea.
• For older students, start planning a Bird Festival for younger students (maybe during Environmental Education Week in April). Use the Flying Wild Curriculum to help.
• Introduce students to literature featuring robins and birds. Help them learn how to use a field guide. 
• Your great idea here.

Sunset: a few weeks later

Date: Sat Feb 7, 2014
Time: 5:49pm
Location: Farm Island river access dock
Temperature: 60°F
Skies: cumulostratus

I arrived home after a conference shortly before 5pm to 70°ish temperatures. I threw on some running clothes and went to Farm Island to run. And a glorious, beautiful run it was too.

 I took this picture after that run, about 5:50pm. Sunset was at 6:01pm.

I could not have done this run two weeks ago, when sunset was at 5:40pm because it would have been dark before I finished.

Unless, of course, I had brought a headlamp and sweater. As soon as the sun gets lower in the sky, temps start falling. They fell during my run which is ok because I was, you know, running.

Skies: Scattered cumulus

On my walk I came across this cluster of feathers.  I assume they belonged to a pigeon, a flock of which seems to live around the apartment house across the street from where I took the picture.

Perhaps a raptor sat in the tree above and enjoyed a nice meal.

The city did a controlled burn of cattails around Mickelson Pond. Since it was a fine day, I took a walk to check it out. I arrived just as the fire trucks were leaving, sadly.

The January thaw continues and probably will for the rest of the week.

The sunset was at 5:41pm.

Sunrise

Date: January 23
Time: 8:23am
Location: Causeway
Temp: ~30°F
Skies: broken altocumulus

Sunrise is still happening relatively late, after 8am. We now have over 9 hours of daylight but the days still feel dark even though they are not particularly cold. Happily, I can tell they are getting longer.

Many geese in the water. There are ducks too. They look like mallards though hard to tell in the early morning sun. The ducks are swimming in the current coming through the culvert under the causeway.  There must be food. 

Nature Journal: Sunset

According to the website timeanddate.com, sunset for Pierre on Jan 20 was at 5:34pm. I took the pictures below at 5:18pm. The first picture demonstrates the length of my shadow just before sunset and the second to the show the sun about 16 minutes before setting.

I didn't look directly at the sun, even through my camera, which made taking the picture interesting. I didn't know what I was going to get in the picture.

Nature Journal: The sound of Chickadees

Date: Jan 19, 2015
Time: 4:02pm
Location: Farm Island Trail, Pierre SD
Temperature: 50°F
Skies: Sunny, clear

According to the Wisconsin phenology calendar I have at hand, black capped chickadees began their spring courtship song on Jan 7.

As with most events of this nature, I think it is more accurate to say that black capped chickadees begin their spring courtship song January 7th-ish.

I took a walk around Farm Island yesterday and recorded some video of the black capped chickadee, mainly to capture the sounds. My phone is not of sufficient quality in either sound or video to do justice to the moment but it's enough to give you the idea. You should crank the volume or listen through headphones.



Scientists recognize that sound provides critical information about ecosystems. Science Friday has several articles  that I have linked below that explore this idea. And of course birders and birdwatchers know that the first time they encounter a bird is usually through sound rather than sight.

Note: If you aren't a birdwatcher, you should begin. Immediately. Birding is a big step and a different thing all together so I will give you a hall pass for that one.

Sound is an important part of experience, any experience. Along with smell and touch (which includes physical movement), sound enriches an experience and helps us "own" it. In my opinion, virtual field trips and experiences will never replace actual field trips and experiences mainly because the sound component is compromised even with "surround sound" and there is a complete lack of smell and touch engagement.

Nothing replaces doing.

Time: 2:15pm

Location: Steamboat Park bike trail; Pierre, SD

Temperature: 45°F

Wind: 5mph

Skies: Scattered Cirrostratus

I took a long, ambling walk on the bike path along the river. I'm enjoying the January thaw, even though it's not a singularity.

Canada geese are winter visitors in Pierre. They number in the thousands in the area due to the open water and, it must be assumed, abundant food.

The geese normally arrive late October, usually showing up just before Halloween. This year they were late, arriving mid November. 

The majority will leave in mid-late March, migrating north. There will be flocks that remain of course. Canada geese here as in most of the rest of the country are opportunistic, establishing themselves wherever there is appropriate habitat.

The wavering, honking, flying Vs are a part of winter here.  At sunset near the water the sound of the geese is loud enough to be heard several blocks away.

Nature Journal: January Thaw

Date: Wed. Jan 15, 2015

Time: 5:48PM CST

Location: Parking Lot, SD Discovery Center, Pierre

Temperature:~ 30°

Wind:5mph

Skies: Broken altocumulus

After several weeks of cold weather where the temperature did not get above the mid 20's, we are finally having a little bit of a January Thaw. I stepped outside of work and snapped this picture mainly because I was struck by how much melt had occurred in the parking lot.

Figure 1: Parking lot. A result of January thaw?

This got me thinking about the January Thaw. January Thaw  was defined in the 1954 Glossary of Meteorology by the American Meteorologic Society as

"A period of mild weather, popularly supposed to recur each year in late January in New England and other parts of the northeastern United States....Statistical tests show a high probability that it is a real singularity." (1)

Elsewhere on the Internet, it is defined as a rise of 10°F over previous weeks' weather (2) or normal highs (1) . There is some discussion over whether the January Thaw is a legitimate weather singularity, i.e a  "characteristic meteorological condition that tends to occur on or near a specific calendar date more frequently than chance would indicate".

I wanted to see for myself what the data in my community said about a January thaw. So I found daily maximum temperatures at the Carbon Dioxide Information Analysis Center  and looked at the daily average  (blue line) and median temperatures (red line)  in Jan from 1934 to 2013 and compared them to the normal January highs (green line).

Figure 2: Average, Median, and Normal January Temps in Pierre by date

The first thing I noticed was that there was not a 10°F spread in either average or median temperatures. The highest average temperature was 30°, the lowest was a smidge below 26°. The median temperatures had a similar spread of 32° and 26° respectively.

There did seem to be some rises above normal on the 10th and 21st of January. But...

All data has variation so it is hard to tell if the rises in the graph above mean anything. The median temperature does go above normal during January but did it happen on a specific date or dates frequently enough to qualify as a singularity?  

So my question became "Is it 10°F greater than an averaged normal of 30°F on a certain date more than 50% of the time?" To find that out, I looked at the number of times that 40° or warmer occurred and on which dates it happened.

Figure 3: Number of times temperatures reached 40° in January by date.

Each of the dates in the data set occurred 79 times between 1934 and 2013. For example, Jan 1 occurred in 1934, 1935, 1936 and so on. For a singularity, the temperature range of 40°F or higher would have to occur 40 times or more on a date.

When you look at our data, there were not any dates that had temperatures of 40°F or higher more than 40 times. 

Ok, maybe I am being too strict with wanting a temperature of 40°F, which you recall is 10°F higher than the averaged normal temperature. Maybe I should dial back my expectations a bit.

So I looked at how many times temperatures above 33°F occurred and on which dates as 33°F is, technically, a thaw and can feel pretty darn good after really cold temperatures.

Figure 4: Number of times temperature reached 33° or above in January by date.

Still the same result. No date had temperatures of 33°F or higher at least 40 times.

Does this mean that the January Thaw is not real?

As far as Pierre SD is concerned, the analysis of this data would indicate the January thaw is not a singularity, a meteorologic event associated with a specific date.

What we do know is that temperatures in January rise above 33°F often enough that our "rule of thumb maker" recognizes a thaw happens frequently, even if it doesn't always happen on or near the same date.

Figure 5: Number of January days above 33° by year.

This chart shows us that temperatures at or above 33°F have happened almost every year. The only year that did NOT have a "warm" day was in 1940. 1937 and 1978 were pretty cold as well, with only one day at 33°F or above.

When you look at the data it is also interesting to note that the number of days at or above 33°F seem to be increasing. 

But that is a question for another day.

Nature Journal: Robins

Date: Tuesday, Jan 13, 2015
Time:5:29 pm CST
Location: Hilger's Gulch, Pierre SD
Temp: ~25°F
Wind:~ 5 mph
Skies: Scattered altocumulus

 I took a walk through Hilger's Gulch and first heard then saw a flock of American robins. I estimate that there were several dozen. For most people in this part of the world, robins are the quintessential bird of spring, who appear on the scene after returning from their migratory trip to the south for the winter.

 There are flocks of robins that overwinter around Pierre and you can usually find them in areas with dense vegetation. I don't know if these robins are local robins that just flocked up and moved to vegetation or if these are robins from farther north who decided that this was as far south as they needed to come.

 I suspect the former but it could be the latter.

Despite this do they/don't they confusion around the migration of these robins, robins are still the heralds of spring as they very clearly exhibit winter and spring behaviors. Robins in winter will be in flocks and have very limited vocalizations, mainly cheeps.

Robins in the spring (actually the late winter) will start slowly spreading out from the flock to claim and defend territory through singing. Around here, this means that they will start moving into town, usually a fine February day when the temperature reaches the upper 30's. A cold snap will send them right back to the flock and silence them again except for their quiet cheeps but it won't be long till they again move out and start singing.

Robin song cheers my winter weary heart. Every year.

I like robins because they are easy to watch, gregarious, and easily habituated to human presence. I like best to watch awkward fledglings learn to fly. They often are not very good and do so with much flapping of wings.

Plus, the Latin name for robin makes my inner 3rd grader snicker. Turdus migratorius.

Nature Journal: Wind

Date: Monday, Jan 12, 2015
Time: 4;54PM
Location: Outside of YMCA, Pierre SD
Temp:  ~10°F
Wind:~ 15 mph
Skies:  Clear

I took this picture to document the wind. The wind is a constant in central South Dakota so learning how to tell wind speed without an anemometer is a handy skill. Probably the easiest way to do this is to learn a modified Beaufort scale which was invented as a visual way of determining wind speed while at sea. I like the one from Wikipedia. I have even further simplified it for my own purposes to be able to form a rough estimate.

Keep in mind that a rough estimate is not the same as taking a reading. The purposes of rough estimates is to stand in for when you don't have equipment. The more estimates you take and compare with readings, the better your estimates will become.

The flag in this picture was flapping which means it drops from time to time. A flapping flag is somewhere between 10 and 15 miles per hour.

~  5 mph: Feel a breeze, leaves moving. (This only works when the trees are in leaf, obviously)
~10 mph: Twigs moving on trees, ripples on water
~ 15 mph: Small branches moving, flags flapping, waves on water
~ 20 mph: Small trees sway, flags waving, waves break with white caps
~ 25 mph: Large branches moving, large flags straight out, large white caps

Below Oahe Dam in Downstream park
Temp ~20°F
Wind - < 15mph
Skies - Broken altostratus


Over the weekend, I went up to the Oahe Dam to look for eagles. Eagles will over winter at the dam as there is open water, cottonwood trees and many Canada geese and ducks. I'd heard rumor that over 60 eagles had been spotted so I had high expectations.

While I didn't see 60, I did see well over a dozen which is usual for this time of year. The best time to see eagles is starting about an hour before sunset as they will start returning to the cottonwoods to roost after feeding.

I saw adult and juvenile Bald Eagles and for the first time ever heard eagles chatter and peal.

Introduction!

Hello!

My name is Anne Lewis and I am the facilitator for this Earth's Explorations online professional development.

When I facilitate a professional development opportunity, I always learn something from the participants. Through this class I want to:

• Improve my understanding of what teachers and out of school program staff need to help students explore the Earth.
• Discover new resources and ideas.
• Learn from the stories and voices that people will share about teaching.

A little about me professionally and personally. I work at the South Dakota Discovery Center as the Special Projects Director. This means I have a lot of varied projects on my plate; everything from overseeing the traveling exhibit program to doing a lot of the IT work. My major responsibility, however, is the environmental education outreach both to teachers and students.

I have my Master's in Natural Science and Environmental Education from Hamline University in St. Paul. I like to trail run (slowly), hike, and kayak. In the winter, I do home improvement projects and read. I like to blog as well, mainly as a way to get my ideas and thoughts out of my head so I can make more sense of them.

I am sharing a picture taken Nov 1, 2014. I went paddling and came upon a beaver dam. This is the downstream side of the dam. I saw other sign of beavers (a slide along the bank, holes in the banks, a few chewed branches with the characteristic point) but no actual beavers. The concern when beaver are present is bacterial contamination of the water.
