Another Sign of Spring

So this picture isn’t the greatest, but i wanted to share it with you anyway.
If you look carefully at the center of the photo, you will see two reddish blobs in the shape of hawks. There are two Red-shouldered hawks that have paired up! There has been a lot of calling, and chasing from these guys the past couple of weeks, but it looks like things have been sorted out and mates have been chosen. To hear the call of this bird click here. We’ve never been able to locate the nest of a pair of these birds, but we know that if they aren’t nesting on the preserve property, they are very close by. 
Red-shouldered hawks are common hawks and enjoy habitat in riparian areas. If you haven’t seen our captive Red-shouldered hawk yet, make sure to stop out and check him out. They are strikingly colored, and a treat to see up-close. 
We’ll be open in less than two weeks! Opening day is March 19th!

Spring is here?

It all depends on how you look at it.

Is it when our first wildflower of the year, Skunk cabbage, blooms?

Is it when tree buds start to swell?

How about when the salamanders run?

Or when the wood frogs lay their eggs?

Maybe it’s when you hear the first Spring Peeper sing?

Perhaps it’s when the first bright yellow daffodil blooms?

When does spring start for you?

Who?

Why the Great Horned Owl of course! These magnificent birds are the earliest nesters in Ohio and right now, we are in the peak of courtship. Here is the link to various Great Horned Owl calls at Cornell’s All About Birds site. By the end of January and first part of February, females will be on the nest incubating eggs. It will take just over a month for the eggs to hatch and then its time to fill hungry bellies! The male has already been hunting and providing food for the nest bound female and he continues to do most of the hunting for the young. Anything he can catch is fair game! Rodents, birds, and rabbits are common prey items but even skunks are on the menu!

Great Horned Owls are very common in Ohio but do like to have forested areas nearby. These owls are typically nocturnal so why not step outside one night and take a listen?

Whooo knows what you might hear??

Whoops!

Please note that there was an error for the What’s that Wildflower Workshop. The correct date is April 26. Thanks!

Updates, Updates…

Hey Gang! Take a look at the right-hand side of the page. There is all kinds of helpful info over there. Take note, that the Open/Close dates for 2014 are now posted! Will Spring Fever be raging in late March? We have the cure! We’ll open the gates starting March 19th! And don’t worry, you’ll have all the way until Nov. 9 to take advantage of the gorgeous fall color – and stock up on Birch Beer for the winter!   😉

Also, take a gander at the 2014 Guided Programs page. I’m pleased to announce a new workshop that was just posted there. Spider expert, author of Common Spiders of North America, and all around nice guy, Richard Bradley will be hosting a day-long spider workshop for us in September! It’s going to be a lot of fun. Remember though for all of our workshops, we require you to register in advance for it. Registration needs to be by phone. (The number is within the program description and on the right-hand side of this page under “Contact Us”.)

Lastly, if you are experiencing a longing for our dear old Wahkeena or want to get out and about in the woods this winter, check out our Winter Off-trail Hike. If you’ve been on our off-trails before you may notice a change in start times. Due to the often long running nature of these hikes, we’ve decided to start them in the morning so we don’t get caught in fading light at the end of the day! This is also a by phone, registration only event. We limit the number of people on the hike so everyone has the chance to hear the naturalist, and see any animal surprises we may encounter. 

If you can’t make it out to the Winter Off-trail, how about a spring one? Our Spring Off-trail Hike is scheduled for March 16. It will be a great way to kick off the official start of spring which will occur on the following Thursday.

In the meantime there are all kinds of places to go and hikes to participate in. A quick internet search will reward you will all kinds of options to keep you busy out of doors this winter.

Snowy Morning

Hi all! Please enjoy this montage of pictures from this morning. It was so pretty, I just had to share!

Warmth Returns!

Not outside, but here in the Nature Center. As many of you know at the end of last winter the old fuel oil furnace bit the dust. Limping along on used parts (as that unit was found to be obsolete) we made it through the rest of the cold weather. Fast forward to the end of October and try as we could, the old furnace was really dead. Until the new system could be installed, we had to use electric oil space heaters. They did okay, but still…..brrr!

Enter in our new heating and cooling system which just happens to be geothermal! It has been pretty exciting and I have some pictures to share with you from the process. These pics are courtesy of one of OHS’s Archaeologists who was on site to monitor the various earth moving activities.

The first step was to drill 3 wells into the earth. This was the start of the first one.

The drilling rig was quite large. This picture is taken from near the back cabin. Can you see how tall the rig is? There are also coils of black flexible pipe that will be inserted down each well.
In preparation for the substances that will come out of the ground as a result of the drilling, a silt fence was put up. This will help guide the mess away from the main walking areas and keep it somewhat contained.

Here is comes! See the grayish white stuff? There ended up being quite a lot when it was all said and done.
 Can you see China?  🙂
Here are all three wells finished. Each well is 150 feet deep.
Next, a trench is dug so that the three wells can be connected together.

This was a pretty big trench! There were some cool pieces of sandstone that were dug up as well as these ugly creatures.

Any guesses? As adults, they provide the classic sounds of summer…..Cicadas! These are the larval form and spend several years underground feeding on sap from plant roots. I’m pretty sure that these are Annual or Dog-day Cicadas and not the Periodical, but if someone out there knows better – let me know!
Check out some of the cool features of this insect. Big eyes, and slender antenna are easily seen. If you look carefully you can see the wing forming that the adult will use to get around. But to me, the coolest feature are the huge claws on the front legs! Wow! They need those big claws for digging. Females lay eggs in twigs and once the eggs hatch the nymph digs its way underground. When it is time to emerge as an adult, the nymph has to dig its way back out again!
Anyway, back to the geothermal system…

At the same time the trench was being dug, a horizontal drilling machine was employed to get pipe from the wells to the Nature Center. This was a neat way to do it because there was no need to excavate another trench. If that had happened, it would have been a big disturbance right in front of the Nature Center.

Tom had previously dug a big hole next to the foundation of the Nature Center. This was so an entry point for the pipe could be drilled through the foundation and into the basement. In the picture above, you can see the entrance of the horizontal driller to the big hole!

Then, it was time for the pipe.

Here is the pipe going into the basement. The hole can be filled in again.
Here is a great shot of how that horizontal drilling save the Nature Center from some ugly and muddy digging.
Now the last step for the outside work was to connect all three wells together and the pipes that go to the Nature Center.
Okay, really the last step was to fill in the trench! Once the grass grows back next spring, you’ll never even know what happened!  
Now with everything connected, the inside work could be done. So our system is called a closed loop system. What that means is that all that pipe that was ran essentially makes one big loop. And circulating through that loop is a special fluid. That fluid becomes the same temperature as the earth around it deep in the ground. The pipes eventually make their way to the furnace and well, that’s where the magic happens. 
As I write this, I am enjoying the warm temperature in the Nature Center and have an good feeling about how efficient and “green” the system is. It’s nice to not rely on fuel oil any more.

A Brand New Orchid!

Can you believe it? We’ve discovered a brand new orchid species for Wahkeena! Confirmed as Spiranthes ovalis or Oval Ladies’ Tresses or Lesser Ladies’ Tresses. It is a fall bloomer and has some of the smallest flowers out of all the other Ladies’ Tresses. Because the one we found was past peak bloom, I do not have a good picture of it to show you! So click here for some photos from Andrew Gibson’s excellent blog, The Natural Treasures of Ohio. The photos of S. ovalis are about halfway down that particular post. While we’ve only found one plant so far, if you’ve read any of the other posts on orchids, you know that there are probably more. I’ve decided that orchids are equipped with cloaking devices and that’s why there are so hard to find!  🙂 It will be very exciting when next fall rolls around to see if this particular plant will bloom again. For those of you who are keeping track, this is orchid number 11 found at Wahkeena!

2014 Programs

Hey Gang!

Check out next year’s Guided Programs by clicking the link in the green bar at the top of the page. We’ve got lots of guided walks, workshops, and much more! Please note that some of our programs do require advanced registration. This must be done by phone. We cannot take reservations via Facebook or email. All of the walks throughout the year however, do not need to be registered for – just show up! We look forward to seeing you all out for our programs next year!

Autumn Coralroot

We finally found (with the help of some good friends) a decent Coralroot to show you. I had found some others earlier in the week, but they were done and not much to look at – and that’s saying something  for this particular orchid! The specimen picture below is the best one that we have found so far. I do have it flagged along the Shelter Trail, and we will give you directions to the spot if you want to see this guy. 
For those of you who are not familiar with this particular orchid, it is quite small. I mean really small. The whole thing isn’t more than a few inches tall and the flowers, such as they are, are tiny.

Above is the best I could do with our new macro lens. This plant is not new, but not totally spent either. There should still be some good opportunities to see it this upcoming week. We will continue to look for additional plants and let you know what we find!
