2019 Annual Bird Report


Great Marsh Institute (GMI) focuses on the Great Marsh in Chester County, PA.  The Great Marsh is primarily owned by the Moore family and French & Pickering Creeks Conservation Trust. The Great Marsh is a periglacial marsh and the largest marsh in Southeastern Pennsylvania, about 700 acres. Surrounding the marsh is shrub swamps, swamp forests, corridors of floodplain forest, upland forest, row crop farming and the PA turnpike.

The Great Marsh supports a large diversity of flora and fauna.  Over 180 bird species and 160 plant species have been identified on the property. There are also large mammals, such as Whitetail deer, coyote, red and silver fox, muskrat and beaver that are present on the property.  Many species of amphibians and reptiles can also be seen at the Great Marsh.  The Great Marsh also has an IBA (Important Bird Area) designation of D3 from Audubon.  D3: Sites that contain rare or unique habitat or are an exceptional representative of an ecological community type, and that hold important species or species assemblages largely restricted to a distinctive habitat or ecological community type.

This report will focus on the avian community along with the associated activities and initiatives during 2019 and into the future.


2019 was a productive year for birding at GMI. Monthly public bird walks and the bluebird monitoring program greatly increased coverage throughout the year in the easily accessed areas of the property. A total of 133 species were confirmed this past year including the following new species: Glossy Ibis (April 21st), Little Blue Heron (July 28th), Blue Grosbeak (October 6th), Golden Eagle (October 13th), and American Pipit (December 27th). These additions bring the total number of species seen to 183 which ranks 10th for eBird hotspots in Chester County.

The Winter season (Dec-Feb) came in with a count of 49 species. Great Marsh hosts a wintering population of Rusty Blackbirds which are rare in Eastern Pennsylvania. Total populations of Rusty Blackbird have declined 85%-95% in the period between 1970-2010. Great Marsh has the unique habitat necessary to host wintering populations and favored areas include the NW sector of the Catfish pond and adjacent thickets and the wet woodlands south of the Spring pond. Other species of note include: Northern Harrier, Eastern Phoebe (late), Winter Wren, Gray Catbird (late), and American Pipit. A notable absence was a lack of Long-eared Owls of which wintering populations have been recorded annually. Habitat improvement efforts which would involve the planting of either an expanded or new White Pine grove may be needed to sustain this species in the future.

The Spring Migration period (Mar – May) had a total of 119 species reported. Great Marsh is one the most reliable locations to see Blue-winged Teal which is considered rare in Chester County. Starting in April, Virginia Rail and Sora return to the property and begin vocalizing and setting up territories. Wilson’s Snipe also migrate through during this period. There was a sighting of a Long-eared Owl in March in the Pine Grove adjacent to the nature center and it is assumed to be a migrant (see above). American Kestrel was reported for three consecutive weeks from mid-March to the first week in April. Kestrel nest boxes have been installed in two areas and we are hoping that this will lead to a breeding pair on the property. Other spring highlights include: Wild Turkey, Glossy Ibis, Common Raven, Purple Martin, Marsh Wren, Purple Finch, White-crowned Sparrow, Hooded Warble (across Rt 401 on Hillside), and Chestnut-sided Warbler.

The Breeding Period (Jun – Jul) had a total of 66 species recorded. This period needs greater study moving forward as summer vacations and activities limited coverage in 2019. Great Marsh hosts breeding populations of Great Blue and Green Herons and the Great Blue rookery at the lower edge of the marsh (technically not on GMI property) is probably the largest in Chester County. The last week of July saw a post-breeding Little Blue Heron visit the property.

Fall Migration (Aug-Nov) hosted a count of 84 species. A post-breeding Great Egret took up residence during September into the first week of October. An immature Golden Eagle was spotted migrating overhead during the second week of October. This is mainly a Western US species and is very rarely seen east of the Appalachians during migration. November saw good numbers of Fox Sparrow and GMI and is one of the most reliable locations to see this species. A notable absence in October was Lincoln’s Sparrow which more than likely was present but was missed. Rusty Blackbirds returned in good numbers in November for the winter. A Blue Grosbeak was recorded the first week of October.

Bird Walks

GMI hosted public bird walks in each month of the year. Scores of visitors were able to enjoy GMI’s unique habitat and avian diversity. This is a program is effective at promoting GMI’s mission. This program was started in 2018 and we are looking forward to continuing it in the future.

Bluebird Trail

In March 2019, volunteers gathered and helped construct and place 12 Bluebird nest boxes around the property to create Great Marsh Institute’s Bluebird trail.  The trail was registered with Project NestWatch, which was created by Cornell Lab of Ornithology.  NestWatch is a nationwide monitoring program designed to track status and trends in the reproductive biology of birds, including when nesting occurs, number of eggs laid, how many eggs hatch, and how many hatchlings survive. The database is intended to be used to study the current condition of breeding bird populations and how they may be changing over time as a result of climate change, habitat degradation and loss, expansion of urban areas, and the introduction of non-native plants and animals. To become a certified Nestwatch monitor, volunteers must read and review Cornell’s nest box monitoring guide and pass a test to register.


The Motus Wildlife Tracking System is an international collaborative research network that uses a coordinated automated radio telemetry array to track the movement and behaviour of small flying animals. Motus is used to track birds, bats, and large insects affixed with digitally-encoded radio transmitters that broadcast signals several times each minute. These signals are detected by receiving stations that scan for signals 24 hours a day, 7 days a week, 365 days a year, depending on the site. When results from many stations are combined, the array can track animals across a diversity of landscapes covering thousands of kilometers.

GMI hosts a MOTUS antenna and Jim Moore has been instrumental in testing and developing the associated technologies. Results can be found here:

American Kestrel Nest Boxes

Two nest boxes were installed in 2019 to attract breeding American Kestrels to the property. GMI has appropriate habitat and it is hopped that these installations will be successful in 2020.

Acoustic Monitoring

We began experimenting with acoustic monitoring systems in the marsh in 2019. GMI was in possession of a Wildlife Acoustics SM-4 recording device as well as an AudioMoth acoustic logger. Deployments were made in various locations and programed to produce audio recordings at predetermined times throughout the day. Results were analyzed using Wildlife Acoustics Kaleidoscope software which produced sonograms that were then reviewed to detect various species vocalizations. In late 2019 we launched a fundraiser that enabled us to purchased five AudioMoth devices that will be deployed in set locations in the marsh in 2020.  


Acoustic Monitoring

With the purchase of additional monitoring devices, there will be a focus on a better understanding the presence and distribution of species in the more remote areas of Great Marsh. A total of six devices are available for deployment starting in April and lasting into May. Some of the target species include known inhabitants such as Virginia Rail, Sora, American Bittern, and Common Gallinule and efforts to detect yet to be recorded species such as King Rail, Least Bittern and Black Rail. While there is no guarantee that the yet to be recorded species will be present, there is appropriate habitat that suggests they are possible. The installation of remote recording devices enables us to record data in some of the remote areas of the marsh on a daily basis.

Purple Martin Houses

Purple Martins have been recorded at Great Marsh in migration periods. The lack of appropriate nesting sites may limit their ability to gain residence during the breeding season. Purple Martins readily accept martin homes and GMI has appropriate habitat to support their presence.

Chimney Swift Tower

The Chimney Swift population has been in rapid decline over the last few decades. These swifts utilize man-made industrial and residential chimneys for roosting and nesting. As industry has changed and more residential chimneys are capped, habitat is rapidly disappearing for this species. Audubon has building plans posted for Chimney Swift towers that this species will readily take to. GMI’s upland open areas can provide a resource to help stabilize their decline.

Long-eared Owl Habitat Improvement

Wintering Long-eared Owls have been present at Great Marsh since at least the 1990’s. The Long-eared Owl population has been showing signs of decline in recent years most likely due to the degradation of the White Pine plantation which is their preferred habitat in this area. This is a species which is considered rare in Chester County and efforts should be made to provide a successional habitat. Ideally a new planting of White Pines of significant size (5 Ft. range) over an area of at least the current pine grove area should be sufficient to ensure the continuation of this rare species at GMI. With that being said, this will require a potentially significant financial investment and a need for fundraising and/or grant money.  


2019 Bluebird Trail Report

In March 2019, volunteers gathered and helped construct and place 12 Bluebird nest boxes around the property to create Great Marsh Institute’s Bluebird trail.  The trail was registered with Project NestWatch, which was created by Cornell Lab of Ornithology.  NestWatch is a nationwide monitoring program designed to track status and trends in the reproductive biology of birds, including when nesting occurs, number of eggs laid, how many eggs hatch, and how many hatchlings survive. The database is intended to be used to study the current condition of breeding bird populations and how they may be changing over time as a result of climate change, habitat degradation and loss, expansion of urban areas, and the introduction of non-native plants and animals. To become a certified Nestwatch monitor, volunteers must read and review Cornell’s nest box monitoring guide and pass a test to register.

Thank you to Joanne and Dave Karkosack who were very dedicated and did an excellent job of monitoring the boxes and recording the data every week.  It was quite a long nesting season with the final brood of three Bluebirds fledging September 6th!  There was a total yield of 16 Bluebird, 30 Tree Swallow and 16 House Wrens that successfully fledged. Next year, we will add a few more boxes at different locations and re-locate a few boxes that had high House Wren activity. “Wren guards” will also be tried on a couple boxes to test their effectiveness.

In 2020 we are hopeful to have an even more successful year than our first and are excited about adding American Kestrel nest boxes to the preserve and starting a monitoring program for Wood Ducks as well. For information about nest box monitoring and placement feel free to contact us!


We are looking for folks that would like to sponsor a nest box for $100.  This donation will help to maintain the nest boxes. In return we will put up a plaque on the bluebird box with your name or you can name the nest box (be creative). If interested please contact Lori Moore, GMI Program Director at

Motus Project Update

You may recall that I reported last year on a bird banding project that GMI is supporting. To recap, MOTUS is a program for deploying automated receivers across the country to pick up coded signals from bird tags. 

We are providing technical support to the Northeast Motus Collaboration (#48) and your scribe is acting as a volunteer technical advisor to this group.  There has been extensive bird tag testing at Marshlands with field tests and also drone missions. 

A technical report has been published where we compare two Motus-compatible tags: The NanoTag and the LifeTag/PowerTag. The “NanoTag” is manufactured by Lotek and has been widely used by researchers using the MOTUS system since the beginning. The LifeTag technology was developed by Cornell University, and has since been licensed to Cellular Tracking Technologies (CTT) from which they have developed the CTT LifeTag and CTT PowerTag. These tags demonstrate greatly improved performance in both detection distance and code identification.  The LifeTag is solar powered and will run forever as long as the sun shines whereas the PowerTag is powered by a tiny battery which works for birds that prefer to travel at night.

We have tested a number of samples of each tag variant and the LifeTag and PowerTag far out perform the NanoTag in detection distance.  The NanoTag is detectable only to about 0.5 km whereas the CTT tags have been detected out to 8 km on tests at Marshlands.  Some recent tag detections have been as far as 40 km over water.  This difference in performance is probably due the higher operating frequency (434 MHz) of the CTT tags compared to the NanoTag (166 MHz) which makes the tag antenna more efficient. The improved coding system provides a better signal to noise ratio which also increases detection range.

For those of you who are interested in the technical details here is a link to the test report.  We are also home to one of over 375 automated receiver systems across the globe.


Summer Bird Walk Wrap-up

The summer season is over and we are now in full swing with fall migration. We had three walks this season with one each in June, July and August. We had a total of 68 species observed including a Little Blue Heron which was a new bird for the property.

Our June walk has held on Sunday the second. June traditionally is a point where most of the species seen can be assumed to be breeding in the area. We took the group into the woodlands above the marsh. A group of five recorded fifty-one species over a three-and-a-half-hour period covering roughly five miles. Highlights included: Bald Eagle, Hairy Woodpecker, Pileated Woodpecker, Great-crested Flycatcher, Veery, and Scarlet Tanager among the GMI regulars.

The July walk took place on Sunday the twenty-eighth. A group of seven spent close to four hours covering a little over three miles. While the birds were starting to “quiet down”, we managed to observe fifty species. The biggest highlight was a Juvenile Little Blue Heron, a first for the property. The group was able to get great looks as it perched on some dead snags in the marsh. Late July into August is when Herons and Egrets disperse from nesting sites into the surrounding areas. Other highlights included: Ruby-throated Hummingbird, plenty of Green Herons, Willow Flycatcher, Yellow-throated Vireo, Swamp Sparrow, and Indigo Bunting.

Things slowed down in August as most species have finished breeding activities and males are no longer actively singing for mates or vigorously defending territories. Birding at this time of year becomes a mainly “site-only” activity and some species can be difficult to detect without an audible hint. A group of six spent about three hours in the heat on Sunday, August eighteenth and covered about three miles. We managed to view forty-three species. Highlights include: Wood Duck, multiple Ruby-throated Hummingbirds, a pair of Cooper’s Hawks, Eastern Wood-pewee, Yellow-throated Vireo, Cedar Waxwing, and Baltimore and Orchard Orioles.

As mentioned at the beginning, we are now entering fall migration and the number of species will start to increase again. Our next walk is scheduled for Sunday, September twenty-second at 7:00AM.

See you out there!

Avian Roundtable

In addition to our monthly GMI bird walks the July 28th walk will include a roundtable discussion at 10:30am of the following topics that should be of interest to fellow birders:

  • Results of our inaugural Blue Bird trail.  Jim Moffett organized a work party to build and install a dozen Blue Bird boxes this Spring.  Our dedicated volunteers, Dave and Joanne Karkosak, are doing weekly surveys of the nest activity which will be reviewed.
  • Mike Coulter has been using GMI’s SM-4 SongMeter to record bird songs in various parts of the Great Marsh.  Mike will discuss his results so far and future plans.  One of which is to apply for a grant from WildLife acoustics for a number of these devices to further studies of bird songs and the effect of Pa Turnpike noise on their activity.
  • Folks from Willistown Conservation Trust will provide an overview of the MOTUS project.  The Motus Wildlife Tracking System is a collaborative research network that uses coordinated automated radio telemetry arrays to study movements of small animals.
  • WCT has received a major grant to build and deploy approximately 40 automated receivers in PA, Delaware and Maryland.
  • GMI has been providing technical support to the MOTUS project.  Jim Moore will do a tour of our MOTUS test antenna farm and provide some results of our tag testing.

We hope you folks can make both events.  For the dedicated birders the walk will start at 6:30AM led by Mike.  If you choose to sleep in the Roundtable will start after the walk – probably about 10:30.

Please contact GMI’s Program director, Lori Moore at 503-544-3868 or if you plan to attend and if you will be arriving at 6:30AM or 10:30AM or anytime in between.  Please check in at the Nature Center when you arrive.


GMI Big Birding Day

For any birdwatcher whether they be professional or casual, May is the highlight of the birding year. Peak migration in the first couple of weeks offers the chance to see and/or hear the greatest numbers of species in a single day.

This year The Great Marsh Institute is offering a unique charity birding experience, The GMI Big Birding Day, for a group of four people interested in experiencing a memorable day of birding while contributing to GMI’s mission to provide scientific and educational studies. This event will be held on Saturday, May 11th 2019. 176 species have been recorded on the property to date and we are hoping to see/hear over 90 species with a possibility of over 100!.  

The plan is to start birding at 6:00AM with a break for lunch at the Nature Center provided by GMI. After lunch we will continue to bird until as much of the property is covered as possible. We will hike, canoe, and utilize a gator to access all of the different habitats. 

GMI has numerous scientific and educational projects in the works and your donation to these efforts should be well rewarded with a great day of birding.

Further details about the event:

This event is only open to 4 participants and the cost is $100 per person. To sign up for this even please contact Lori Moore:



March 17, 2019 Bird Walk

GMI’s March bird walk had a group of 14 birders’ enjoying the first signs of spring migration. The morning started off with a fly-by Bald Eagle cruising over the marsh. The catfish pond and the upper marsh hosted a pair of American Wigeon along with numerous Wood Duck, Canada Geese, Green-winged Teal and a pair of Black Duck. The first American Tree Swallows made their appearance as well as a FOY Eastern Phoebe. 
Heading out the the marsh and onto the lane, a group of 80 Snow Geese were observed migrating overhead. A beautiful Yellow-bellied Sapsucker in fresh plumage was seen as well. The first Fish Crows of the year were flyovers announcing themselves with their signature nasal calls. 
The wet woods near the turnpike gave the group excellent looks of at least a dozen Rusty Blackbirds and a very accommodating Pileated Woodpecker working the base of a tree at about 30 yards. 
All in all we observed a total of 45 species.
The next walk will be on Sunday, April 14th with a start time of 7:00AM as sunrise will be at 6:26AM. 
See you out there.
