Hepatica acutiloba - flowers are bursting open all around! |
I had an excuse to get outside in the fact that I am in need of more owl pellet samples to process for my research. I've incorporated a diet analysis (mammalian prey only) of owls and other raptors into my thesis research in the Cuyahoga Valley National Park (CVNP) as an additional method to detect small mammal species. I really enjoy this method because walking around the woods looking for owls is fun, finding pellets is exciting, and identifying animal remains from the pellets can be even more exciting!! It is a great addition to my methodologies because I want to discuss various detection biases etc. via different methods of inventorying mammals. The major downfall of this method is that I cannot pinpoint where the prey item was dwelling before being captured by the predator. While it is likely that most of these prey are found within the territory of the hunter, and that average territory sizes are known for these animals, I cannot associate these animals with any particular measured habitat characteristics, nor can I confirm a status of an animal in the park this way. Regardless, I believe that it is still a worthwhile pursuit, and in the end I will have another dataset to assess the composition and relative abundances of small mammal communities in the CVNP.
Can you see any pellets or bone fragments in this photo?? |

As another mass came by tromping, and climbing, a middle-aged man yelled out to me "Louisiana Waterthrush?!"
Caught again by surprise, I looked at him and smiled "Yeah, I was hoping to find one, have you guys seen or heard any?"
My new favorite stranger continued running, "No, I've been listening for one though!"
(You probably wouldn't hear it because the 40 runners in front of you already put it into hiding)
How awesome I thought!!! I can't believe that one within this mass group of people (who I initially assumed that I wouldn't share many common interests with) not only knew what a Louisiana Waterthrush was and how to find one, but he knew that today was the day that they should be returning all over Northeast Ohio, and that it might be what I was was seeking! Made my day and I'm still smiling about it.
Hepatica sp. is probably my favorite spring wildflower if I had to pick one. Here is a phone shot that I snapped today (left) and a better shot that I took in the past (right). This flower can be white (most common), pink, purple, or blue! So beautiful :)
I'm going to find one I thought. As I continued up stream, the last stragglers were gone and I now had the woods to myself, with only evidence of a small stampede along the trail. I was approaching this very special and beautiful section of stream and I figured that I would look for owl pellets nearby because I had heard a pair of Barred Owls (Strix varia) here in the past. Almost there and a rock that was too good not to be flipped called my name. When I turned it over I saw a lead-phase Red-backed Salamander (Plethadon cinereus) and something that I haven't seen before under a rock - a cicada larvae! Oh my, is this a Magicicada?? Too much of a tangent to discuss in this post, but the 17-year Periodical Cicadas will be emerging in Northeast Ohio this summer and I can't wait!!! I think I found one early! (Although a few emerged last year)
Continuing on, I took a moment to look around me and be thankful for the Eastern Hemlocks (Tsuga canadensis) all around me and I even said a little prayer for them. Telling them that I want them to survive the danger that likely stands in their future with the Wooly Adelgid infestation (another tangent but see here for some basic info http://www.dcnr.state.pa.us/cs/groups/public/documents/document/dcnr_007179.pdf)
Eastern Hemlock is my favorite tree, and it is more than just a tree. Beyond the fact that they are charismatic, long-lived, and gorgeous, hemlocks foster their own ecosystem in which many plants and animals rely on. These trees grow mostly on north-facing slopes and in deep ravines as they are a shade-loving species. Their root systems are amazing and they can hold on tightly on the steepest of slopes, just like Yellow Birches (Betula allegheniensis). A hemlock population will create a darker and damper microclimate in a place, and year-round needles adds extra depth and cover for wildlife or wild people, like me. Many plant and animal species that are typically found in more northerly latitudes can be found in isolated populations in hemlock forests, extending their range. If we lose hemlocks, there will certainly be a chain-reaction in the ecosystems and we many species will leave with it. I would be very sad to see that. Next time you are out in the woods and you come upon a stand of hemlocks, maybe just give them some extra love :)
Ok so the story must end soon...and this is why I rarely write blog posts - they take way longer than I want them to!!
The story ends with me in the magical spot as my final destination, and you know who was waiting for me there :)
After watching the butt-bobbing beauty (you just have to see one for yourself to know what I'm taking about) for a bit, I walked into the darkening hemlock stand where I had heard an owl in the past. I'm getting a pretty good feel for where owls like to roost now as a product of my research. I looked around and said to myself "If I was an owl, where would I sit?"..."This spot looks pretty good"...sure enough found a bunch more pellets :)
Disclaimers - I rattled these latin names out of my brain so I apologize if a letter or two is wrong :D I don't think that a whole species name would be wrong - LOL
These photos are either from my phone or ones that I have taken in the past, I don't have time or proper equipment to make any new pretty ones right now...

March 31, 2016 was a beautiful day.
