Monday Phenology: Weird Mini Edition

Posted by Kirk 2 Comments
I'm taking the phenology a bit easy this holiday week but there were some sightings to share. Just between you and me let's call this a Mini-Midweek-Phenology-looking-at-last-week-thing. 

These are all from the week previous, not this week.

Monday I was really noticing the dark. We're so close to the solstice the days are pretty short now. The lack of snow makes it seem not as bad though, at least in my opinion.

Tuesday I saw a bald eagle fly over the nature center as I walked to the front door in the morning. After lunch, my co-worker Paul and I decided to take advantage of the nice weather to cut down some large Buckthorn seed trees. On our walk down the driveway we heard our first Black-capped Chickadee singing the spring Hey Sweetie song. An excellent early sign of spring and the solstice was still two days away.

Wednesday was a wonderful winter solstice. The sun was still below the horizon and there was a light coating of frost on the ground as I stepped outside. I was able to watch the sun rise during my long commute to work. It was a gorgeous orange globe as it rose through the trees. When I got close to work, a trio of trumpeter swans rose out of a corn field and flew across the road in front of me, heading toward the rising sun. Absolutely perfect start to the day. It turns out about a dozen swans are hanging out in a corn field near work.

Thursday I had the day off so I dropped off my son at school, swung by work to photograph th Trumpeter Swans in the corn field and then headed down to Point Douglas Park just outside of Hastings MN/Prescott WI, on the St. Croix River. There had been a report of a long-tailed duck there and I wanted to check it out. The wind coming down the river seemed bitterly cold but I've felt worse in other winters. Point Douglas Park is a popular destination for birders on new-year's day. There's usually a small group there trying to kick off their year list with a rarity. For the past few winters this has been the site of an overwintering harlequin duck. On cold winters the water just north of the park and also under the bridge to Wisconsin is some of the only open water around and all kinds of good things can be found. It is a great place to see birds but dress warmly. This year with the warmer weather it was quite challenging to find anything as the open water extends for a good distance up river from the park. Some birds were even out of range of a spotting scope. I saw hundreds and hundreds of Common Mergansers, a small flock of Canada geese and a random smattering of common goldeneyes. The goldeneyes were of particular interest as reports had it that the long-tailed duck was very loosely hanging out with them. I scanned back and forth in the cold with no sign of the duck. Before I gave up I thought I would check down by the bridge. What I saw there was disheartening. The river was open for a good distance downstream as well. There was a good chance the duck was on the other side of the road with no good safe spot to set up a scope. Before packing things in I decided to scan the water again from this other angle. Sure enough, a ghostly camouflaged bird appeared in my scope. It was the long-tailed duck and it was a lifer. I took a good look and then decided to try again from my original spot. It should have given me a much better view but alas, I could not relocate the elusive bird. Too much water, too much cold.

Friday I drove my son to school and saw something cool along highway 36. There must be open water somewhere because there is a flock of mallards that fly over the highway throughout the winter. (Incidentally, I know of at least one location with open water all year, there is a little creek behind the Mueller-Bies funeral home on Dale St. near Hwy 36. I've seen mallards there in the middle of the winter.) The mallards I saw on Friday weren't flying in a big group but rather in pairs, if the Chickadees singing at the beginning of the week was the first sign of spring, this is the second. Pair flights are an early sign of spring mating. The birds pair up with their mate and fly together as a way to strengthen the pair bond.

I'd normally tell you at this point what to watch for in the week ahead but it is already Wednesday and the week ahead is already half over. The normal podcast will resume Monday, January 2nd. Enjoy the winter!

Monday Phenology: December 19, 2011

Posted by Kirk 4 Comments





We're getting pretty close to the solstice and the numbers sure show it. Sunrise today was at 7:47 AM and sunset at 4:33 PM. That's 8 hours, 46 minutes and 12 seconds of sun. Today's daylight was only 14 seconds shorter than yesterday. There's actually something really interesting hidden in those numbers. The solstice is the coming Wednesday but most people don't realize the solstice is neither the day of the latest sunrise nor the day of the earliest sunset. It is simply the shortest day. The sun set has actually already started to get later in the day. As of today, the sun is setting one full minute later than it did just a few days ago. The sun rises will continue to get later for a little over a week or so and then they too will reverse course.

Your week in review:

Last Monday I mentioned that in the week ahead people should listen for Black-capped Chickadees practicing their spring "Hey Sweetie" song. Listerner/reader Marcie dropped me a note in the comments saying she had indeed heard heard them singing down near Lake Pepin on Monday. How cool is that? Not even to the solstice yet and we have our first sign of spring. On Twitter, Rebecca sent me a message that she had heard them as well. She's over in North-eastern Wisconsin.

Wednesday on the drive home I noticed the first ice house on an area lake. I'm told it was there earlier in the week and I just missed it. It probably put up on the weekend. Wednesday it rained all day so I imagine that cemented the ice house in real well. Should be fun to get out at the end of the winter. The weather was just bizarre Wednesday. It was foggy and misty rain that just would not let up or go away. I went out to dinner that night and didn't bring a winter jacket of any kind. I just wore just a sweatshirt. How may years can I do that in the middle of December?

Thursday morning we had a very light coating of snow but nothing the sun couldn't take care of. It all seemed to be pretty much gone by the end of the day. On the drive to work I saw one lone swan flying south. Then, closer to work, I also saw a pair of swans flying. I wondered what was making them move around that morning? Was it a coincidence I saw them? There can't be that much open water around for them except on rivers. During the day there were just a few flakes but mostly it just got colder and windy by the end of the day. There were some very brief peeks at a blue sky.

Friday there were also some brilliant peeks at blue skies and sun. It was incredibly unseasonably nice out but that was just a preview of Saturday and Sunday. 

Saturday was a beautiful day weather wise and that night I taught an astronomy program. The skies were clear and gorgeous. I haven't seen such clear nice skies for astronomy in a long time. Jupiter was out and we got a nice look at the cloud bands as well as the four largest moons. For an extra treat I turned the scope on the Andromeda Galaxy. At 2.5 million light years away it is the furthest object you can see with the naked eye. If you look closely in the right spot in a dark location you can just make it out even without magnification. Pretty incredible to think about how far away it is.

Sunday was insane weather wise. It was in the 40s in the twin cities but out in Montevideo they hit 61°. That's just crazy. I don't have high hopes for my snowshoe program scheduled for next week.

The week ahead:
Sun lovers rejoyce! For the last six months I've been telling you how many minutes of sunlight we've been losing. Fear not. The upward trend begins on Wednesday which is the solstice. From mid-week on we'll be seeing more and more sunlight each day. The longer we go without snow on the ground the harder it will be for winter to really take hold as well. As sunlight increases so does our heating during the day. Last winter seemed like it would never end. At least so far it looks like we could be in for a pretty short winter.

The Corprophagic Mouse

Posted by Kirk
A couple of weeks back I mentioned an interesting find on one of our automated cameras. My co-worker Paul had wanted to capture photos of the raccoon using our back steps as a fecal depository. Raccoons are what we call Proud Poopers and they like to leave their waste in conspicuous spots. There were three photos on the camera that appeared blank. Here's an example.


It just looks like an empty shot of the stairs. We have the camera set to take three photos in rapid succession so there were three of these shots.  We scrolled between the photos to see if something moved. Even a leaf blowing across the stairs could trip the camera. We were surprised by what we found.

Monday Phenology: December 12, 2011

Posted by Kirk 2 Comments
Monday morning the sun rose at 7:41 AM and it set again at 4:31 PM giving us 8 hours 49 minutes and 33 seconds of daylight. I get off work at 4:30 so that means I technically had one minute of daylight to enjoy after work. Wheee. Monday was 47 seconds shorter than Sunday.


Nature's Week in Review:

I was a little lax on the phenology for the first half of the week. Tuesday it was cool with light snow. There were beautiful delicate flakes in the air. Some of my co-workers and I spotted some smaller than one would expect Canada Geese in a spring fed pond near the St. Croix River. We got into a debate over what they were exactly.  I think they were smaller than the Common Canada Goose. There were perhaps 5 of them but there were only mallards for size comparison, not other geese. This really complicated the matter. Were they really smaller than normal or just messing with our heads. They were larger than the mallards but not hugely larger and did appear to have small bills but then again, compared to the geese in our heads. When it comes to telling all of the various forms of smaller geese apart I'm not sticking my neck out. There are a lot of people who will see any goose smaller than the full size and instantly call it a cackling goose. I'm not so sure I could make an ID like that on these. I'd be willing to bet a good number of "cackling" geese people see are actually "Lesser" or "Richardson's" Canada geese though to make things confusing Richardson's and Cackling have been lumped together to make Cackling a separate species and Richardson's a sub-species of cacking. Confused? There are differences other than size but if you're viewing a flock at a distance and you go just by size are you 100% sure you can tell the difference between a 27 inch long Richardson's and a 25 inch long Cackling? How about a small Richardson's and a large Cackling that are the same size? Can you really id a 1 to 2 inch boy length difference in a goose at 50 yards? Check out this primer.

I made some general observations Wednesday and Thursday. I noticed the first Muskrat holes in the ice on area lakes this past week. They gnaw holes in the ice and then push vegetation up though the hole. You can see these muddy piles all over the place. Muskrats are active all winter and like to get on top of the ice when they can for a breather.

With the coating of snow on my yard I found many tunnels in the area of my bird feeder. I don't get to see many rodents around the yard so seeing signs of them in the winter is interesting.

English House Sparrows have set up their winter shop in my yard. My god there are thousands of them. Well, okay, maybe just over 30 but it seems like a scene from The Birds every time I walk outside.

Around the metro and state there continue to be many reports of snowy owls. I haven't seen one yet but I've done plenty of distracting driving looking for them.

Friday there were pale blue skies and cold it was cold out. I was happy to see the sun and blue but this usually means it will be colder if we don't have that warm blanket of clouds at night. There was a Lunar eclipse at moon rise. I hope you all got to see it. It was beautiful.

Saturday: I taught a birthday party program and there was lots of deer sign in the woods. Saturday was the first day we lost less than a minute of sunlight. As we approach the solstice we loose less and less each day. Today was 56 seconds shorter than yesterday. The solstice is just 9 days away. Incidentally, December 21st will be four seconds shorter than the 20th so we're getting to the point where you can't really notice a difference. Congratulations, we're already pretty much as dark as it will get.

Sunday was a beautiful warm day. This is December? The small ice dams on my roof started to melt away along with all the snow on the ground. We picked up a Charlie Brown tree, set it up in the living room and then started to do the only sane thing we could do on a warm day in December. We started painting the house. Is this some bizarre cabin fever setting in early? Stay tuned in to find out. One room done, two more to go.

This week:
Continue to watch out for Snowy Owls which should be easier to spot on the brown ground which lacks snow. Also let me know if any of you hear Chickadees singing their spring "Hey Sweetie" song this month on these warm days. This is usually the first sign of spring though can we count it if it happens before the solstice?

The heat was out in out building this morning when I came to work. Laptop+WiFi+huge fireplace means the work goes on.
