Wildflowers of the Indiana Dunes National Park

Indiana University Press has published a number of nature-themed field guides and books, in recent years including guides such as Butterflies of Indiana, Mammals of Indiana, Fishes of Indiana, 101 Trees of Indiana, and Wildflowers and Ferns of Indiana Forests. The latest in this series is Wildflowers of the Indiana Dunes National Park.

When Nathanael Pilla asked me to work with him on a wildflower guide for the Indiana Dunes National Park, which had very recently seen a status change from a National Lakeshore to a National Park, it had not been long since I had agreed to work with Michael Homoya on another book project, Wildflowers of the Midwest. I might have initially told Nathanael that I didn't have time to help with this project, but he assured me that I could work on the project with Mike and when that was finished, pick up from wherever he was in the process of writing Wildflowers of the Indiana Dunes National Park and help from there. Living less than an hour from the Indiana Dunes and knowing that there wasn't a good field guide to that part of Indiana, I agreed to work with Nathanael on this project.  Less than three years later, Wildflowers of the Indiana Dunes National Park is available from IU Press (https://iupress.org/9780253060419/wildflowers-of-the-indiana-dunes-national-park/) as well as at various other book vendors.

We hope you enjoy the book!

Wildflowers of the Midwest

Timber Press has worked with botanists around the United States to develop their wildflower guide series.  Prior guides include Wildflowers of the Atlantic Southeast, Wildflowers of Texas, Wildflowers of the Pacific Northwest, Wildflowers of the Rocky Mountain Region, and Wildflowers of New England.

In 2019, Michael Homoya asked me if I would be interested in co-authoring the latest part of this series, Wildflowers of the Midwest.  How could I say no to this opportunity?  I talked it over with Lindsay, knowing that I was already extremely busy, but she encouraged me to go for it, as opportunities like this don't come around very often.  

Working on this guide, which covers herbaceous plants (minus ferns and graminoids) in the eight-state Midwest region (Minnesota, Iowa, Missouri, Illinois, Indiana, Ohio, Michigan, and Wisconsin), occupied nearly all of my time on weekends and weeknights after work for over two years.  I am happy to announce that the guide is now available for purchase from the publisher (https://www.workman.com/products/wildflowers-of-the-midwest/paperback) as well as at various other book vendors.

Enjoy!

2017-2018 Winter Bird Feeder Count Results

Sadly, the formal Indiana Audubon Society Winter Bird Feeder Count came to an end after the 2016-2017 season, as coordinators were not seeing enough participation from birdwatchers around the state to make it worth continuing this annual count.  This is surprising to me, as the Winter Bird Feeder Count is one of the easiest counts to conduct, and counters don't even need to stand in the cold or drive in the ice and snow to record the birds they're seeing.  Regardless, I decided to keep conducting the count and managing my own resulting data.  The 2017-2018 season was my 10th consecutive, and I'm starting to see some trends in the birds visiting our feeders during this count period annually.  During this count, 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.  For our results from all but the 2008-2009 Winter Bird Feeder Counts, see our past posts: 2016-20172015-20162014-20152013-20142012-20132011-20122010-2011, and 2009-2010. 

The summed average number of individuals observed during the 2017-2018 count was 143.25, third only to results seen in 2015-2016 (202.5) and 2008-2009 (154.25).  We tallied 21 species at our feeding stations during the count, the lowest tally we've had, tying results from 2009-2010, 2011-2012, and 2013-2014 (29 species is our high for the count period, observed in 2015-2016).  The number of species observed was below our ten-year average of 23.60 species. We tallied an average of 17.5 species per month (ranking near the middle of our average species per month through our 10-years of doing the count).  We observed 14 species in November 2017, 18 species in December 2017, 20 species in January 2018, and 18 species in February 2018.  For comparison, our 10-year monthly averages stand at 17.2 in November, 17.9 in December, 18.1 in January, and 19.6 in February.  In general, numbers seem to increase both as we get closer to spring and when more snow and colder temperatures are present.

Winter feeding of our birds, including this Black-capped Chickadee, began on October 15, 2017.
The list of species observed during our 2017-2018 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 Sharp-shinned Hawk (Accipiter striatus), Northern Flicker (Colaptes auratus), American Crow (Corvus brachyrhynchos), Brown Creeper (Certhia americana), Carolina Wren (Thryothorus ludovicianus), American Robin (Turdus migratorius), Gray Catbird (Dumetella carolinensis), Yellow-rumped Warbler (Setophaga coronata), Eastern Towhee (Pipilo erythrophthalmus), Field Sparrow (Spizella pusilla), Song Sparrow (Melospiza melodia), White-throated Sparrow (Zonotrichia albicollis), Snow Bunting (Plectrophenax nivalis), Rusty Blackbird (Euphagus carolinus), Common Grackle (Quiscalus quiscula), Common Redpoll (Carduelis flammea), and Pine Siskin (Carduelis pinus).  I observed a Song Sparrow at our feeders between the count periods and three Song Sparrows eating food in our driveway the day after the February count period ended.  We also had Northern Flicker and American Crow near our feeders between the count periods.  An American Robin showed up in our yard shortly after the February count period concluded.

We've now tallied 38 species using our feeders (or hawks showing an interest in feeder birds) during the 10 seasons that we've participated in this count (reported erroneously as 37 in last year's report).  We didn't add any new species to our tally during the 2017-2018 count.

Tufted Titmouse is a regular winter feeder bird, showing up during all four count periods in 2017-2018.
The low temperature during our 2017-2018 count was 15 degrees Fahrenheit in December and the high temperature reached 62 degrees Fahrenheit in February.  November and December temperatures during the 2017-2018 Winter Bird Feeder Count on our property were slightly below the average, but January and February were much warmer than average for the second consecutive year.  Snow cover was mostly within the range of other counts, with the exception of December, when there was the most snow of any December period in our 10-year history (8 inches).  Also of note is that the February period saw 0 inches of snow for just the second time, with the first time this happened occurring last year.  Low and high snow cover totals were below average throughout the count, except for the high snow cover total in December, which was above average.  The deepest snow cover during the count was observed in December (8 inches).

A female Red-winged Blackbird (top left) showed up at our feeders during the January count period; two males were present in February.
Species observed most frequently (those present during all four count periods) in 2017-2018 were Red-bellied Woodpecker, Downy Woodpecker, Hairy Woodpecker, Blue Jay, Black-capped Chickadee, Tufted Titmouse, White-breasted Nuthatch, American Tree Sparrow, White-crowned Sparrow, Dark-eyed Junco, Northern Cardinal, House Finch, American Goldfinch, and House Sparrow.

House Finches (female on the left, male on the right) were most abundant at our feeders in January.
Species observed in greatest abundance during a single month of the count (with the greatest number observed at one time in parentheses) were American Tree Sparrow (13 in January), Dark-eyed Junco (12 in January and 11 in February), Northern Cardinal (11 in January and 11 in February), Brown-headed Cowbird (250 in December), House Finch (20 in January), American Goldfinch (22 in November), and House Sparrow (14 in December and 10 in January).  The most abundant species based on average over the four months of the count were Brown-headed Cowbird (65.0) and American Goldfinch (10.3).

American Tree Sparrow numbers at our feeders have shown a decline in recent years.
A few species we've documented over the years with seemingly interesting trends in numbers are Mourning Dove, American Tree Sparrow, Fox Sparrow, White-crowned Sparrow, and Purple Finch. Mourning Doves increased steadily from 2008-2009 to 2011-2012, then decreased fairly steadily to 2015-2016, and their numbers have remained fairly constant for the past few years.  American Tree Sparrows increased slightly to a maximum in 2011-2012 but then have generally decreased over the next six seasons.  Fox Sparrows were first documented at our feeders in 2010-2011, were not seen for the next two seasons, and then have been a regular at our feeders during snowy periods to present.  White-crowned Sparrows are a surprising winter regular at our feeders; their numbers generally decreased from 2008-2009 to 2013-2014, but have increased to 2008-2009 numbers into the 2017-2018 season.  Purple Finches were not observed at our feeders until 2015-2016, but have been a regular occurrence during the count period since.

An average high count for Purple Finch (male shown above) was documented in 2017-2018 at our feeders.
We logged average high counts for 3 species in 2017-2018: Hairy Woodpecker (2.00), White-crowned Sparrow (3.00, tied with 2008-2009), and Purple Finch (0.75).

2017 Grass Identification and Ecology Workshops to be Offered at The Morton Arboretum

For several years I have led a very popular and relatively inexpensive grass identification and ecology workshop at The Morton Arboretum.  I will be leading that workshop again this summer.  In addition, for anyone who has taken that workshop in the past or who takes the workshop this year, there will also be an advanced grass identification workshop following the first workshop.  Information on the workshops follows.  If you know of someone who may be interested, please spread the word.

------
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 workshops discussed below being held on September 5-6 and 7-8, 2017 at The Morton Arboretum in Lisle, Illinois may be for you.  If you have any questions about the workshops, email Scott Namestnik at snamestnik@orbisec.com.




Learn to identify the grasses that add beauty and interest to the summer and fall landscape. Grasses allow us to read the landscape: from soils, habitat, disturbance and past land uses. They form a critical component of the biodiversity and with nearly 11,000 species, this is the fourth largest plant family. This workshop consists of an intensive, hands-on approach incorporating both classroom work and field study.  Identify warm season grasses in the field and lab, learn the specialized terminology and distinguishing features, discuss their ecology, and practice identifying species from keys. 
Instructor: Scott Namestnik, senior botanist, Orbis Environmental Consulting
Notes: Held both indoors and outdoors. Please dress for the weather each day. Limit 20
Supplies: Please bring a water bottle, a hand lens, and wear sturdy, closed-toed shoes for walking over uneven terrain. Fee includes all workshop handouts, morning refreshments and a box lunch.
Intended audience: Advanced students and professionals.
Prerequisites: Prior experience with plant identification required
Course number: 
S318
SCHEDULE AND LOCATION: 
Tuesday, September 5, and Wednesday, September 6, 2017, 9:00 a.m.to 4:00 p.m.

IN PERSON: Stop by the Visitor Center during open hours.

Expand your grass identification skills in this expert workshop. You've taken the first step towards learning the specialized terminology used to identify grasses, and you've learned some common woodland, prairie, and wetland grasses. Now it's time to delve even deeper into the complex world of these economically and ecologically essential monocots. This workshop consists of an intensive, hands-on approach incorporating both classroom work and field study.  We will use what we've learned in the introductory grass identification and ecology workshop as we become more comfortable using dichotomous keys to identify several grasses in the lab. We'll then incorporate our learning in the field as we learn key identification characteristics of even more grass species in varied habitats.

2016-2017 Winter Bird Feeder Count Results

Well, it seems that I have no time to add to this blog anymore, but since I've discussed our results from the Indiana Audubon Society Winter Bird Feeder Count since 2009-2010, I don't want to stop now. During this Indiana citizen science project, 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.  For our results from all but the 2008-2009 Winter Bird Feeder Counts, see our past posts: 2015-20162014-20152013-20142012-20132011-20122010-2011, and 2009-2010. 

In 2015-2016, we saw the greatest summed average of individuals of any of our counts (202.5).  In 2016-2017, our summed average of individuals dropped by nearly 100 (108.75).  We tallied 26 species at our feeding stations during the count, which ranks third for all of the years we've participated in the count (we had 29 species in 2015-2016 and 27 species in 2008-2009; 21 species in 2009-2010, 2011-2012, and 2013-2014 are our low counts).  The number of species observed was greater than our nine-year average of 23.78 species. We tallied an average of 19.5 species per month (ranking third behind 21.0 species per month in 2015-2016 and 20.5 species per month in 2008-2009).  We observed 18 species in November 2016, 22 species in December 2016, 16 species in January 2017, and 22 species in February 2017.  Our nine-year monthly averages stand at 17.6 in November, 17.9 in December, 17.9 in January, and 19.8 in February.  In general, numbers seem to increase when more snow and colder temperatures are present, and we didn't have much of either in 2016-2017 (as discussed below).

We began putting out bird food for our winter birds, such as this male Downy Woodpecker and female Northern Cardinal, on October 1, 2016.
The list of species observed during our 2016-2017 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), Carolina Wren (Thryothorus ludovicianus), American Robin (Turdus migratorius), Gray Catbird (Dumetella carolinensis), Eastern Towhee (Pipilo erythrophthalmus), Field Sparrow (Spizella pusilla), Snow Bunting (Plectrophenax nivalis), Rusty Blackbird (Euphagus carolinus), Common Grackle (Quiscalus quiscula), Common Redpoll (Carduelis flammea), and Pine Siskin (Carduelis pinus).  We had an early Pine Siskin before the November count period, but this was not an irruption year for Common Redpolls or Pine Siskins, so it is not surprising that we did not have either of these northern visitors at our feeders during the count period.

We've now tallied 37 species using our feeders (or hawks showing an interest in feeder birds) during the nine seasons that we've participated in this count.  A Yellow-rumped Warbler (Setophaga coronata) showed up and was eating bird food from under a feeder during the February 2017 count period, marking the first time during the Winter Bird Feeder Count in the nine seasons we've participated that we have observed this species.

A single Song Sparrow was present under our feeders in December 2016 and February 2017.
The low temperature during our 2016-2017 count was 14 degrees Fahrenheit in December and the high temperature reached 63 degrees Fahrenheit in February.  November and December temperatures during the 2016-2017 Winter Bird Feeder Count on our property were within the range of previous years, but January and February were much warmer than average. January saw the highest low temperature during the nine-year history (36 degrees Fahrenheit) and the highest high temperature during the nine-year history (61 degrees Fahrenheit).  February saw the second highest low temperature during the nine-year history (28 degrees Fahrenheit, second only to 33 degrees Fahrenheit in February 2016) and the second highest high temperature during the nine-year history (63 degrees Fahrenheit, second only to 67 degrees Fahrenheit in February 2016).  The low temperatures were below average in December but above average in November, January, and February, and the high temperatures were below average in November and December but well above average in January and February.  Snow cover was within the range of other counts, with the exception of January and February, when there was less than 1 inch of snow for the first time in any of the counts during our nine-year history.  Low and high snow cover totals were below average in November, January, and February.  The deepest snow cover during the count was observed in December (6 inches).
 
We tallied between 3 and 6 Downy Woodpeckers at our feeders during the count.
Species observed most frequently (those present during all four count periods) in 2016-2017 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), Dark-eyed Junco (Junco hyemalis), Northern Cardinal (Cardinalis cardinalis), Brown-headed Cowbird (Molothrus ater), House Finch (Carpodacus mexicanus), American Goldfinch (Spinus tristis), and House Sparrow (Passer domesticus).

House Finches were present during all four months of the count.
Species observed in greatest abundance during a single month of the count (with the greatest number observed at one time in parentheses) were American Crow (Corvus brachyrhynchos, 28 in December), European Starling (Sturnus vulgaris, 15 in December), American Tree Sparrow (13 in December, 10 in January, and 12 in February), Dark-eyed Junco (10 in December, 10 in January, and 10 in February), American Goldfinch (22 in November and 23 in February), and House Sparrow (32 in November and 25 in January).  The most abundant species based on average over the four months of the count were House Sparrow (17.0) and American Goldfinch (14.0). 
 
White-crowned Sparrow numbers took another hit at our feeders in 2016-2017.
White-crowned Sparrow (Zonotrichia leucophrys) numbers have been a roller coaster during the nine seasons we have participated in the count.  From 2008-2009 to 2013-2014, this species declined in number of individuals at our feeders from an average of 3.0 to an average of 0.3.  In the next two seasons, numbers increased back to an average of 2.3. In 2016-2017, we found an average of just 0.5. We'll need to keep a close eye on this species moving forward.

We had not observed White-throated Sparrows at our feeders during the first six seasons of the count, but they've been present in the past three seasons.
We logged average high counts for 9 species in 2016-2017: Sharp-shinned Hawk (Accipiter striatus, 0.50), Red-bellied Woodpecker (2.75), Hairy Woodpecker (Picoides villosus, 1.75), Northern Flicker (Colaptes auratus, 0.50), White-breasted Nuthatch (3.50), Yellow-rumped Warbler (0.25), White-throated Sparrow (Zonotrichia albicollis, 0.50), Dark-eyed Junco (9.50), and Purple Finch (Haemorhous purpureus, 0.25).

2015-2016 Winter Bird Feeder Count Results

Lindsay and I have participated in the Indiana Audubon Society Winter Bird Feeder Count during each of the past eight winters.  During this Indiana citizen science project, 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.  For our results from all but the 2008-2009 Winter Bird Feeder Counts, see our past posts: 2014-20152013-20142012-20132011-20122010-2011, and 2009-2010.

Northern Cardinals were the fourth most abundant species at our feeders during the 2015-2016 count.  The bird in this photo is a female.
In the past couple of years, I'd reported that we may be seeing a trend of a decreasing number of individuals visiting our feeder.  That changed this year, as we had a greater summed average of individuals in 2015-2016 (202.5) than in any other count period during our history of the count (second highest is 154.25, observed in 2008-2009). 

Like several other species, Northern Cardinal numbers were higher at our feeders this year than in any year in the past.  The bird pictured is a male.
In terms of number of species observed at our feeding stations during the count, we had our best count ever in 2015-2016, tallying 29 species (27 species in 2008-2009 is our next highest count; 21 species in 2009-2010, 2011-2012, and 2013-2014 are our low counts).  The number of species observed was greater than our eight-year average of 23.5 species. We tallied an average of 21.0 species per month (edging out our second highest average of 20.5 species per month in 2008-2009).   We observed 24 species in November 2015, 17 species in December 2015, 24 species in January 2016, and 19 species in February 2016.  Our eight-year monthly averages stand at 17.5 in November, 17.4 in December, 18.1 in January, and 19.5 in February.  In general, numbers seem to increase when more snow and colder temperatures are present.

American Goldfinch numbers have shown a decreasing trend over the eight years of observation at our feeders during the Winter Bird Feeder Count. 
The list of species observed during our 2015-2016 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 Sharp-shinned Hawk (Accipiter striatus), Gray Catbird (Dumetella carolinensis), Eastern Towhee (Pipilo erythrophthalmus), Field Sparrow (Spizella pusilla), Snow Bunting (Plectrophenax nivalis), Common Redpoll (Carduelis flammea), and Pine Siskin (Carduelis pinus); a Sharp-shinned Hawk showed up the day after the January count period.  This was not an irruption year for Common Redpolls or Pine Siskins, so it is not surprising that we did not have either of these northern visitors at our feeders this season. 

This Sharp-shinned Hawk was not tallied during the Winter Bird Feeder Count at our feeders, but showed up on January 26, 2016, one day after the count period ended.
We've now tallied 36 species using our feeders (or hawks showing an interest in feeder birds) during the eight seasons that we've participated in this count.  Species observed at our feeders for the first time during the Winter Bird Feeder Count in 2015-2016 include Carolina Wren (Thryothorus ludovicianus) and Purple Finch (Haemorhous purpureus).

The Carolina Wren on the right provided our first ever record of this species at our feeders during a Winter Bird Feeder Count.
The low temperature during our 2015-2016 count was 11 degrees Fahrenheit in November and the high temperature reached 67 degrees Fahrenheit in February.  Temperatures during the 2015-2016 Winter Bird Feeder Count on our property were mostly within the range of previous years with the following exceptions: November saw the lowest low temperature during the eight year history (11 degrees Fahrenheit), February saw the highest low temperature during the eight year history (33 degrees Fahrenheit), December saw the highest high temperature during the eight year history (62 degrees Fahrenheit), and February saw the highest high temperature during the eight year history (67 degrees Fahrenheit). The low and high temperatures were below average in November but above average in December, January, and February.  Snow cover was within the range of other counts during each month.  Low snow cover totals were below average each month in 2015-2016, and high snow cover totals were above average in November and February but below average in December and January.  The deepest snow cover during the count was observed in February (7 inches).

Dark-eyed Juncos are common winter residents.

This female Red-winged Blackbird hung around into November.
The most abundant species based on average over the four months of the count were Brown-headed Cowbird (78.5), American Tree Sparrow (14.8), Red-winged Blackbird (14.5), Northern Cardinal (11.5), House Sparrow (11.3), House Finch (10.8), and European Starling (10.0). 

Fox Sparrows have shown up during our feeder count the last three years and four of the last six years.  This year was the first time we had more than one.  During the Great Backyard Bird Count (just before the February feeder count period), there were four Fox Sparrows feeding on cracked corn in our driveway at one time.
White-crowned Sparrows continued to rebound at our feeding stations in 2015-2016.  From 2008-2009 to 2012-2013, this species declined in number of individuals at our feeders from an average of 3.0 to an average of 0.3.  In 2015-2016, we found an average of 2.3 White-crowned Sparrows at our feeding stations during the count period.  Mourning Doves (Zenaida macroura), however, have been decreasing at our feeders during the feeder count since 2011-2012 (to an average of 2.3 in 2015-2016).  House Finches have increased fairly consistently since we've been conducting the count, whereas American Goldfinches have shown a generally decreasing trend.
