Orchids Are Weeds
Okay, so maybe saying that orchids are weeds is a bit of a dramatic exaggeration. However, while mowing the trails on our St. Joseph County, Indiana property yesterday, I had to slam on the brakes inches from mowing the fourth orchid species that we've documented on our property, October Lady's Tresses (Spiranthes ovalis var. erostellata). If you're a follower of this blog, you may know that the previous three orchids we'd found on our property were Ragged Fringed Orchid (Platanthera lacera), Purple Twayblade (Liparis liliifolia), and Green Twayblade (Liparis loeselii). After finding the third of those, I asked readers of this blog (tongue in cheek) which orchid species we would find next. Keith Board has to win some kind of prize for predicting that we would find this species. My find today is even more interesting because I saw this species growing on the St. Joseph and Elkhart county line on Friday last week and came home to look for it on our property in a young successional wooded area. I struck out. I guess I was looking in the wrong place and instead needed to be sitting on a riding mower to find it.
Sure, a weed is often defined as a plant out of place. In that sense, I don't necessarily consider orchids weeds. However, the more I see and learn, the more I think that many of our orchid species require disturbance to grow, reproduce, and continue to be evident above ground, and without that disturbance, they cease to exist (at least until the disturbance returns) (see the dialog in the comments of this post for a discussion on this topic). In this case, the orchid I found is growing right at the edge of the trail that I mow regularly, in old-field, with mostly non-native species and weedy native species such as Tall Fescue (Schedonorus arundinaceus), Riverbank Grape (Vitis riparia), and Poison Ivy (Toxicodendron radicans ssp. negundo).
As seen in the photograph below, the flowers of October Lady's Tresses (also known as Oval Ladies'-tresses) are usually in three spiraling ranks. The flowers (and specifically the lip) are smaller than many of the other members of the genus Spiranthes, with the lip reaching only approximately 5.5 mm; the other two species that have flowers that minute in the lower Great Lakes region have either a yellow or green spot on the upper surface of the lip. The lip on October Lady's Tresses is quite recurved and is usually inrolled, giving it a narrow appearance. Another good field character used to help identify October Lady's Tresses is seen in the photograph above... notice that the leaves are present and conspicuous when the plant is in flower.
Whereas many of our Spiranthes grow in full sun habitats, October Lady's Tresses is more shade-tolerant and does best in openings in woods, along trails, and in young successional woods. It also is found in thickets and in old-fields. When forests mature and less light can reach the forest floor, this species tends to be less prevalent, an indication that it requires disturbance. You can see the habitat where I found the plant on our property in the photograph below (it is just about in the middle of the photo). Not an area that anyone would consider "high quality" by any means.
The range of October Lady's Tresses includes the eastern United States and the province of Ontario. However, it is not known from more than a large handful of counties in any of the states in which it occurs, and its county distribution is fairly even over its range. That said, this species is increasing its range and distribution, likely in part due to the increased level of disturbance to our natural areas. So... is it just a weed? Certainly a unique and welcomed one on our property!

Frog Monitoring Comes to a Close
During the last two nights I conducted my third of three sets of frog and toad call monitoring for the year at five sites for the FrogWatch USA citizen science program. This year was a pretty good year for my sites, as I logged 10 of the 11 species that could be expected in the South Bend, Indiana area:
- Wood Frog (Rana sylvatica)
- Western Chorus Frog (Pseudacris triseriata)
- Spring Peeper (Pseudacris crucifer)
- American Toad (Bufo americanus)
- Northern Leopard Frog (Rana pipiens)
- Pickerel Frog (Rana palustris)
- Blanchard's Cricket Frog (Acris crepitans blanchardi)
- Eastern Gray Treefrog (Hyla versicolor)
- Green Frog (Lithobates clamitans)
- American Bullfrog (Rana catesbeiana)
Calling Eastern Gray Treefrog in South Bend, Indiana, June 25, 2014 |
It's always a treat to get to see how these tiny frogs produce such a loud sound. The video below shows a calling Eastern Gray Treefrog.
Frog and toad calls are starting to wind down a bit for the year, but that only means that the singing insects are just getting started. Now is the time to start listening for them as they fill the night with their characteristic melodies.

A Rare Treat
If you follow this blog, you know that I am a big fan of the milkweeds (Asclepias spp.), not only for their unique flower morphology but also for their importance to a long list of insect species. It is no surprise, then, that on a recent trip to Starved Rock State Park near Utica in LaSalle County, Illinois, I had to stop to snap a few shots of the somewhat uncommon Poke Milkweed (Asclepias exaltata).
Unlike many of our milkweeds that grow in open to partly shaded conditions, Poke Milkweed thrives in rich soils and grows in partly shaded to shaded conditions of woodlands and forests. Its range includes much of the eastern part of North America, extending west just past the Mississippi River into Minnesota and Iowa.
Although it isn't necessarily considered a species of conservation concern, when you are lucky enough to find Poke Milkweed, you generally don't see it in large numbers. According to Swink and Wilhelm (1994), Poke Milkweed can be absent or found in very small numbers in a given forest for many years, and then inexplicably it will be found in great numbers in the same woods.
The flowers of Poke Milkweed are interesting in part because they are bi-colored. The corolla lobes (petals) are greenish-yellow, whereas the hoods of the corona are white to faintly pink.
Although it has opposite leaves with milky sap, the leaves have a texture and venation that can superficially be confused with the alternate-leaved Pokeweed (Phytolacca americana), giving rise to the common name Poke Milkweed. This similarity was noted by Frederick Pursh, who assigned the Latin name Asclepias phytolaccoides to this species. The older name Asclepias exaltata, assigned by Carl Linnaeus, is the currently accepted Latin name.

Scenes from the Hill Prairie
Late May is a spectacular time on the gravel hill prairie. The gravel provides a low-nutrient substrate that keeps vegetation competition to a minimum, and as a result several prairie species that are generally not as competitive have the opportunity to thrive. The photographs that follow are from 28 May 2014 on a gravel hill prairie in McHenry County, Illinois.

Grass Identification and Ecology Workshop to be Offered at The Morton Arboretum
UPDATE: THE AUGUST 21-22, 2014 WORKSHOP IS SOLD OUT. A SECOND SESSION IS BEING HELD ON SEPTEMBER 17-18, 2014. RESERVE YOUR SPOT TODAY!
Tired of seeing "unknown grass" and "Dichanthelium sp." on your vegetation sampling datasheets? Need to know what species that Elymus is to figure out if you're in a wetland or an upland? Interested in learning vegetative characteristics for some of our more common grasses? Just want to know more about grass identification and ecology in general? If the answer to any of these questions is "yes," then the workshop discussed below being held on August 21-22, 2014 at The Morton Arboretum in Lisle, Illinois may be for you. If you have any questions about the workshop, email Scott Namestnik at snamestnik@orbisec.com.
GRASS IDENTIFICATION AND ECOLOGY WORKSHOP

Spring is Mustard Season
In early April I made a trip down to extreme southern Indiana with Mike Homoya and Roger Hedge to see a unique spring ephemeral native mustard in bloom. Our target was Michaux's Gladecress (Leavenworthia uniflora), and we weren't disappointed. We met up with Jason Larson and Derek Luchik to see this little gem.
Michaux's Gladecress is a tiny plant, with the largest specimens only reaching about seven inches tall when in flower; most plants are much shorter than this. As an annual calciphile that can't tolerate competition from other plants, Michaux's Gladecress is restricted to areas with limestone at or near the surface, such as glades, rocky old fields, roadsides, and rocky ledges. In Indiana, this habitat is only found in the southeastern part of the state, near the Ohio River.
Limestone glades aren't common in Indiana, and as a result Michaux's Gladecress isn't common in the Hoosier State. Even within the glades that are present, this little mustard is really only found in areas of nearly bare soil; it is more common in areas with exposed limestone that are near but not in the glades. In areas meeting this description, the species can be rather abundant, growing in tiny cracks in the limestone or areas where a miniscule amount of soil has accumulated.
Michaux's Gladecress is only known from Missouri, Arkansas, Alabama, Georgia, Tennessee, Kentucky, Ohio, and Indiana. In Indiana, its populations are restricted to Clark County, and as a result it is listed as endangered; globally it is apparently secure (G4).
What a great way to start off the botanical year!

Cooper at Bendix Woods
Lindsay, Cooper, and I took a quick walk this afternoon at Bendix Woods County Park in St. Joseph County, Indiana for me to prepare for a field trip I am leading there next weekend for Shirley Heinze Land Trust. Lucky for us, Cooper loves hiking, and he seemed right at home with the blooming Trillium grandiflorum, Enemion biternatum, and Asarum canadense.
Happy dog!!
After hiking at a new park, Cooper seems amazingly more calm when we get home.

An Uncommon Visitor
I can get used to this working from home gig. Nearly every day for the past two weeks I've watched Bald Eagles (Haliaeetus leucocephalus) fly past my office window, including one mature eagle at very close range flying up my driveway being chased by a blackbird. Just a couple of days ago, we had another visitor that probably would have gone unnoticed had I not been working from home.
The chunky, brown, streaked body, conical beak, and bold white eyeline help to identify this bird as a female Purple Finch (Haemorhous purpureus). We've only observed Purple Finch on our property a few times; this is the first female that we've seen. In many bird species, the females are more difficult to identify because they are less colorful than the males and look similar to females of other species. In the case of the Purple Finch, the male is definitely more colorful, appearing to have been "dipped in raspberry juice" according to famous American naturalist Roger Tory Peterson, but the female is actually more easily identified. Male Purple Finches are often confused with male House Finches (Carpodacus mexicanus), but female Purple Finches are easily distinguished from female House Finches because of the white eyeline that the House Finch lacks.
Purple Finches are in northern Indiana only in winter; they spend their summers further north of here in moist, cool forests. Their populations seem to be decreasing, and some think this may be a result of competition with the invasive House Finch.
I can't wait to see what species I can add to our yard list working from home this spring once songbird migration is well underway.

Changes
There have been some changes at the Namestnik house recently. First, after over 15 years at JFNew and Cardno JFNew, I left my job and founded Orbis Environmental Consulting with a bat/wildlife biologist and an archaeologist. Check us out on the web, on Facebook and on LinkedIn.
Then, a week ago, we became the proud parents of an 8 month old Australian Cattle Dog puppy named Cooper.
Wish us luck!!

2013-2014 Winter Feeder Count Results
Lindsay and I recently completed our sixth consecutive Indiana Audubon Society Winter Bird Feeder Count, an easy and fun citizen science project during which the greatest number of each bird species observed at feeders in your yard on the 20th to 25th of November, December, January, and February are tallied. Although I mentioned to Lindsay a couple of times during this count how active our feeders were nearly every day, our results show that the number of individuals has been decreasing since we started the count in 2008-2009. For our results from past Winter Bird Feeder Counts, see our posts here (2012-2013), here (2011-2012), here (2010-2011), and here (2009-2010).
Looking back at data from our counts over the years, it quickly becomes apparent that 2008-2009 must have been a standout birding season, as we tallied 27 species at our feeders during that count but have not had more than 23 since. During the 2013-2014 count, we were just under our average from the previous years of 22.8 species, as we tallied 21. We had 14 species in November 2013 (the fewest total number of species ever during our counts), 15 species in December 2013, 17 species in January 2014, and 20 species in February 2014. The 20 species we observed in February was the most in any month of the Winter Bird Feeder Count on our property since the 2008-2009 count, when we had 20 species in December and 25 species in February.
The biggest discrepancy in results from this year versus the average of past years was in November and December, as we observed three fewer species than our average numbers during each of those months. We began feeding a bit later this year than in past years, so it is possible that it takes the birds a little while to find our feeders once we start feeding for the winter and that if we had started feeding earlier in the winter/fall of 2013 our number of species observed in the early months of the count might have been more comparable to our average.
The list of species observed during our 2013-2014 Winter Bird Feeder Count is found at the end of this post. Species not observed during this count that we have seen on at least one other count include Cooper's Hawk (Accipiter cooperii), Northern Flicker (Colaptes auratus), American Crow (Corvus brachyrhynchos), American Robin (Turdus migratorius), Gray Catbird (Dumetella carolinensis), Eastern Towhee (Pipilo erythrophthalmus), Snow Bunting (Plectrophenax nivalis), Rusty Blackbird (Euphagus carolinus), Common Redpoll (Carduelis flammea), and Pine Siskin (Carduelis pinus); however, the first four of these were seen on our property (just not at the feeders or during the count period) this winter. Conspicuously absent from our feeders (and those of others in this area) in 2013-2014 were the winter finches (such as Common Redpoll and Pine Siskin). We've tallied a total of 31 species using our feeders (or hawks showing an interest in feeder birds) during the six seasons that we've participated in this count.
It was much colder and we had more snow during the 2013-2014 Winter Bird Feeder Count than in the past few years, but the temperatures and snow cover during the count periods were similar to those in 2008-2009. The low temperature during our 2013-2014 count was -7 degrees Fahrenheit in January and the high temperature reached 45 degrees Fahrenheit in February. The deepest snow cover during the count was observed in January and February (8 inches).
Species observed most frequently (those present during all four count periods) in 2013-2014 were Red-bellied Woodpecker (Melanerpes carolinus), Downy Woodpecker (Picoides pubescens), Blue Jay (Cyanocitta cristata), Black-capped Chickadee (Poecile atricapillus), Tufted Titmouse (Baeolophus bicolor), White-breasted Nuthatch (Sitta carolinensis), American Tree Sparrow (Spizella arborea), Song Sparrow (Melospiza melodia), Dark-eyed Junco (Junco hyemalis), Northern Cardinal (Cardinalis cardinalis), House Finch (Carpodacus mexicanus), American Goldfinch (Spinus tristis), and House Sparrow (Passer domesticus).
Species observed in greatest abundance during a single month of the count (with the greatest number observed at one time in parentheses) were House Sparrow (17 in December), American Tree Sparrow (16 in December, 15 in February, and 12 in January), American Goldfinch (12 in February), Mourning Dove (Zenaida macroura) (11 in January), and Brown-headed Cowbird (Molothrus ater) (10 in February).
Just as in 2012-2013, one of our most notable observations during this count was a lack of White-crowned Sparrows (Zonotrichia leucophrys). The decline in number of individuals of this species at our feeders, from an average of 3.0 over the count period in 2008-2009 to an average of 0.25 over the count period during the past two years, may be indicative of their shifting population, as reports show that their numbers are increasing in parts of the continent but decreasing in other parts.
Another notable observation in 2013-2014 was the presence of a Fox Sparrow (Passerella iliaca) during three of the four months of the count. This was only the second time during a Winter Bird Feeder Count that this handsome reddish brown and gray bird has made an appearance at our feeders (also present during the 2010-2011 count), and on days when it was present it stuck around almost the entire day.

There's Still Time to Participate in the 2014 Great Backyard Bird Count!
The 2014 Great Backyard Bird Count has reached its halfway point. If you haven't had a chance to participate in the first two days of the count, hopefully you can count birds and submit a checklist on Sunday or Monday. Saturday was an interesting day in the field in northern Indiana, with many birds (Black-capped Chickadee, Northern Cardinal, Red-winged Blackbird, and Red-bellied Woodpecker, among others) singing their spring songs.
