Deirdre Robinson presents at EBBA 

Deirdre Robinson gave a presentation at the 100th anniversary meeting of the Eastern Bird Banding Association in Newtown Square, PA, on March 25, 2023. Preliminary findings were offered comparing the measurements of sparrows that we captured in 2022 with museum specimens that were over 100 years old. A discussion followed, raising questions about the potential impact of rising temperature on bill surface areas and leg lengths, as adaptations to dissipate body heat.

First Record of White-tailed Deer Depredating Saltmarsh Sparrow Nests

During the Summer of 2022, the SSRI carried out field work using trail cameras placed near Saltmarsh Sparrow nests at Jacob's Point in an effort to identity nest predators. Although we had limited success, we had one major finding: we captured two instances where it appeared that White-tailed Deer were eating SALS eggs out of the nests. To our knowledge, this is the first recorded evidence of this behavior in a salt marsh environment. White-tailed deer have been seen to eat eggs of ground-nesting birds in other environments, so this is not too surprising. The results of our study will appear this spring in the journal Northeastern Naturalist. In the meantime, we've provided a link (above) to a pre-publication copy of the article. Since deer are a very abundant, this finding provides a new challenge to those working to improve the survival odds for threatened saltmarsh birds.

Joel Eckerson presented on possible changes in Saltmarsh Sparrows due to climate change at the 100th annual meeting of the Association of Field Ornithologists

A full report of this research will be published in the coming year. Here is a brief summary.

ABSTRACT 
Saltmarsh Sparrows (SALS) are obligate saltmarsh specialists that breed in habitats that are open and unshaded, where fresh water is limited, and convective winds are common. Thermoregulation has been suggested as a driver in selecting bill size, since larger surface areas radiate more heat. We explored whether Allen's Rule (extremities vary in size with temperature) would apply to SALS morphometrics by comparing 64 modern adults captured in the 2022 breeding season at Jacob's Point in Warren, RI, with 57 adult SALS museum specimens that were collected in June-August between 1860 and 1930 at similar latitudes. Using a digital caliper, one team member measured the Nalospi, bill Height and Width at the same distal nares site; tarsus, and wing chord of all 121 birds. We calculated bill surface area (SA) using the formula SA=(H+W)/4*N*π. We calculated means and standard deviations and conducted t-tests. Although the sexes are monomorphic, males are exposed to more UV radiation and heat than females due to behavioral differences; we hypothesized that if selection acts toward larger bill surface area, it would likely be evident in males. There were no significant changes in any metrics for females. With the exception of longer wing chords in males vs females in the modern samples (57.66mm vs 54.41mm, p=0.000), there was no sexual dimorphism. However, we did find a significant decrease in bill SA in modern males vs museum specimens (21.28mm vs. 20.34mm, p=0.008), which is counter-intuitive. We also found increasing mean tarsus length in over time (19.08mm vs 20.62mm, p=0.000), which may act as a thermoregulatory appendage in this species as temperature has increased over the past 160 years.

Seekonk High School AP Biology Class Visits SSRI Study Site

At the request of Seekonk High School biology teacher Angela Cunard, SSRI Co-Director Steve Reinert met Ms. Cunard's AP Biology class at the Audubon Aquarium and Nature Center in Bristol. The group, including the high school librarian, Sue Larson, walked to the Jacob's Point salt marsh where Steve spent an hour discussing salt marsh formation, the relationship of the lunar and tidal cycles, and the breeding ecology of the Saltmarsh Sparrow. Steve stressed the threat that rising sea levels present to the sparrows, and urged students to "think globally and act locally" towards combating the negative impacts of climate change on our estuaries.

Jim O’Neill Named as SSRI Co-Director

Because of his many contributions to the SSRI team for the past four years and the leadership role he is assuming for the team’s 2022 field efforts, Jim O’Neill (see bio here) will join Deirdre Robinson and Steve Reinert as SSRI Co-Directors. Jim’s breadth of skills—whether it be using GPS to map nests, building share-able web pages for entering field observations, generating maps of our study site, or managing the SSRI web site at www.salsri.org—our team simply could not have met its research goals without his contributions.

 

Jim is the Swiss Army Knife on our team. Whatever needs to be done—building bridges over creeks, banding birds, repairing net-poles, or providing technical solutions—Jim does it competently and with good nature. Biking to Jacob's Point, Jim has likely witnessed more sunrises in the past 4 years than during his decades-long previous career. Yet the sun never seems to set on his willingness to be the Help Desk for all team members. 

 

During the 2022 field season, Jim is directing SSRI's first intervention project. He will use a Godzala grant from the RI Natural History Survey to purchase motion-detection cameras to identify the predators of Saltmarsh Sparrow nests. Eventually we hope to receive permits to test designs of wire-mesh baffles to protect eggs and nestlings of this threatened species.

A Developmental Guide to Aging Saltmarsh Sparrow Nestlings

Rhode Island Naturalist has just published a guide to aging SALS nestlings written by Deirdre Robinson. This a photo guide was created to aid our team in determining the age of Saltmarsh Sparrow nestlings in the field. We hope it will be of  service to other researchers working with SALS.

Why is it helpful to determine the age of a SALS nestling? 
The short answer is that it allows researchers to document the early development in the life history of this endangered species and correlate breeding success or failure with nestling age. Finding a nest with any combination of eggs and young allows us to retroactively determine when the nest was constructed and the first egg laid. This data informs us about potential changes in the breeding cycle over time as well as how the nesting cycle is impacted by flooding or depredation events.

SSRI Receives Gift in Memory of Martha J. Tebbenkamp

In honor of his wife, Martha Jane Tebbenkamp, who passed away in August of 2019, Bill Reinert, brother of SSRI co-director Steve Reinert, has donated $1,500 to the Saltmarsh Sparrow Research Initiative. Martha and Bill had been married for 32 years at her passing; they lived in Portland, Oregon. She was an honored government employee, finishing her career as an inspector with the Federal Bureau of Tax and Trade. Martha loved the birds that visited her yard, especially a pair of flickers that she named Fred and Fiona, and ruby throated hummers she called Mr. and Mrs. H. She placed a variety of feeders around the yard, and nurtured blooms aimed at attracting birds.

She was passionate about animals in general, volunteering as a property inspector with the Oregon Humane Society, and donated much time, money, and goods to charities dedicated to animal and human welfare. Knowing that Martha would support the work of SSRI, Bill made the donation in her name.

Bill said, "Martha was an avid proponent of conservation, and would have been very happy to have helped this cause.

COVID-19 Causes Changes to SSRI Project for Summer 2020

On the recommendations of the North American Banding Council, and to maintain consistency with partnering Saltmarsh Sparrow research teams in the Saltmarsh Habitat and Avian Research Program (SHARP), we are suspending all group bird banding operations this season, due to COVID-19.  A solo bander will color-band targeted birds only.  We will continue to monitor nests and tides. The workshop scheduled for May 16, 2020 is cancelled, along with all group banding dates this summer. Thank you for your interest in volunteering with this project and please check our website for updates and announcements for the 2021 banding season at Jacob's Point.
With our best wishes,
Steve, Deirdre, Jim, & Joel

Preliminary Update on Summer 2019

In the third summer of our project, we banded 14 adult female and 20 adult male Saltmarsh Sparrows, and documented the return, since 2017, of 15 marked females, 33 marked males, and 3 SALS banded as nestlings. In 2019 Jacob's Point Salt Marsh provided breeding-season habitat for a minimum of 84 adult SALS (63% males). It was a great summer! Many thanks to our loyal, hard-working volunteers!  Over the three years of our project, we have documented the fate, microhabitat, and elevation of 85 nests found during the three breeding seasons.
