State College
Bird Club Zoom Meeting
January 25, 2023
Presiding: Doug Wentzel
Recording: Peggy Wagoner Saporito
Attendance: 35
Meeting Format: Zoom
Announcement/Old Business update
Doug updated us on the current state of the recently established
SCBC endowment fund with Centre Foundation. Initially the fund was
set up with $12,500 coming from the SCBC savings account. Members
generously added an additional $2,500 during the month after
establishment of the account. Centre Foundation matched our funds
resulting in a total endowment of $29,497. This total should
generate an annual income each June of around $1,300 and will be
used to support bird conservation activities in our region.
Treasurer’s report: (Karen Kottlowski):
The SCBC checking account balance is $4,278.72 and saving account
balance, is $5,573.77, which is reduced compared to last month due
to funding the endowment.
Bird Club Field Trips: (Susan Smith)
Susan is scheduling spring field trips. The first will be March 19
with more information to follow.
Announcements/Other Activities:
Thanks to everyone who participates in the various bird counts
through the colder months. The Christmas bird count
compilers have done a massive amount of work again this year to
pull together results of last month’s counts. Other counting
activities that have recently completed, are on-going and will be
coming up include winter raptor surveys, hawk watches, and the Great
Backyard Bird Count, Feb 17-20: https://www.birdcount.org/
Our annual meeting to share photos and sounds from the
past year will be on May 24. Nick Bolgiano and Betsy Manlove are
organizing this event. Information about how to submit photos and
audio can be found in the ‘Meetings and Field Trip Schedule’
section on our website: https://www.scbirdcl.org/
The Huntingdon Arts Council is sponsoring a show, Old Crow
through the Seasons in early February. See their website for
more information: https://huntingdoncountyarts.com/?page_id=575
There have been questions about how best to access the Duck
Pond for viewing birds. The chain link fence that currently
blocks access to the area will be removed by late summer or early
fall after access improvements are completed. In the meantime,
viewing from the grounds of Centre Mansion Furnace is the safest
option.
The annual meeting of PSO (PA Society of Ornithology) will be held
at the Ramada Inn in State College, May 19-21, 2023. This is the
first year that the meeting will be a Birding Festival
with speakers and field trips open to participants. Registration
for this event will be coming soon. Deb Grove has been sending
emails to the listserv to keep us informed.
Nick Kerlin continues his work on the SCBC history
project, spanning a period from establishment in 1941 to the
present, with interviews and reviewing documents at Pattee
library.
Notable Bird Sightings: (Dec 14, 2022 – Jan 25, 2023;
Centre and its contiguous counties)
Since Greg Grove was unable to join us tonight, individuals
entered their interesting sightings into the Zoom chat. With
today’s snowfall, tree sparrows were noted at some feeders in the
area.
Speaker: Carl Engstrom: “Summer with the Tides: Fieldwork
in the Saltmarshes of New Jersey”
Carl, a recent Penn State graduate, grew up in State College with
a lifelong passion for birds. He described his work during summer
2021 with the Saltmarsh Habitat and Avian Research Program
(SHARP): https://www.tidalmarshbirds.org
Hurricane Sandy inspired interest in tidal saltmarsh habitats
because of their ability to protect coastal areas from the ravages
of severe weather. As a result of Hurricane Sandy, SHARP, a
collaborative project among several state, federal and university
entities from Maryland to Maine, was established in 2011 to
support tidal marsh bird conservation through population studies
and to propose solutions to prevent serious declines in these
species and their wetland habitats. Funding for the project
continued through 2022 but will not be continued beyond.
In the US, saltmarsh habitat is found only along the eastern
seaboard. It requires a long time to form but much of the original
saltmarsh has been destroyed by human development and what remains
is fragmented and largely surrounded by development.
Currently, the greatest threat to saltmarsh habitat is sea level
rise due to climate change. Carl showed us 2 maps of the saltmarsh
area adjacent to Manahawkin Bay in southern NJ. The current map
shows a fairly healthy area of saltmarsh, though it is surrounded
by development. The map projecting sea level rise in 40 years,
shows the estimated 2-foot rise which will completely submerge the
existing saltmarsh around Manahawkin Bay. Since it is surrounded
by development, the habitat can not expand into high elevation
areas and will therefore be completely lost.
To evaluate saltmarsh bird populations and habitat, Carl described
the random point count techniques used. Because saltmarsh habitat
is so fragmented, not all of the random points sampled were
actually saltmarsh.
At each point, bird species were noted through sight, sound and
call back response to recorded bird calls. Vegetation was also
assessed. Healthy saltmarsh vegetation is dominated by Spartina
grass with tall grass Spartina in areas which flood with the
tides, and short grass Spartina in slightly higher elevations that
do not regularly flood.
Carl discussed the four obligate saltmarsh bird species of
greatest interest in the study: Clapper Rail, Eastern Willet,
Atlantic Saltmarsh Sparrow and Seaside Sparrow. One third or more
of the total populations of each of these four species is found in
NJ.
Clapper Rails, an omnivorous species spends the entire year in
saltmarsh habitat. It is a ground nester with large clutches (2-16
eggs) of precocious young. Although populations have been
declining 5% per year since 1998, this is still a game species
with a hunting season, Sept 1- Nov 21.
Eastern Willet, a large formerly hunted shorebird, nests on the
ground with clutches averaging 4 eggs. There is no evidence of
population change since 1998.
The Atlantic Seaside Sparrow never leaves the saltmarsh. Its
relatively long bill, for a sparrow, allows it to have a variable
diet. Nests contain 2-5 eggs and are built a few inches off the
ground above the waterline, protecting eggs and young from high
spring tides. Though there is no evidence of population decline
since 1998 for this subspecies of seaside sparrow, the story of
its Florida relative, the Dusky seaside sparrow, which went
extinct in 1987, provides a cautionary tale if habitat is not
protected.
Split from the Nelson’s sparrow in 1995, the Saltmarsh Sparrow
lives only along the coast and may be the next to go extinct. Its
breeding strategy may help it to survive for a bit longer. As a
nonterritorial species, males, with no need to sing to establish
territories, have no real song. Instead, they roam around the
saltmarsh breeding with females that can mate with several males.
They are ground nesters, laying 3-6 eggs. With a 11-12 day
incubation period, eggs and nestlings are susceptible to high
spring tides. Compared to other passerines, saltmarsh sparrow
nestlings have a bit more mobility and manage to scramble up
nearby vegetation to escape minor flooding events. If nesting
fails, female may breed again if failure occurs within the window
of opportunity for nesting. However, these strategies did not help
in 2021 when there was a late May high water storm along the NJ
coast which caused a total failure of saltmarsh sparrow nests. The
species has been declining by 9% annually since 1998 with a 75%
population loss from 1998-2012. Unfortunately, decisions about
listing this species as vulnerable have been postponed until fall
2023.
In addition to studying bird populations, SHARP proposed solutions
to the threats facing saltmarshes. Protecting the edges of
saltmarshes from development will allow saltmarsh habitat to
expand into new areas as sea levels rise. Eliminating Phragmites,
an invasive species which outcompetes the essential Spartina
grasses, will improve the health of habitat for birds and other
saltmarsh species. Strategically establishing ditches in
saltmarshes could alleviate some of the pressures created by
higher tide levels. On a small scale, floating islands anchored to
the substrate can be built and planted with Spartina. Rising and
falling with the tides, these structures do not flood and have
supported nesting sparrows.
Carl also described some other fun encounters with birds and other
creatures he had during his summer working with SHARP. Currently a
grad student at Ohio State University, Carl is now studying how
cerulean warbler populations are impacted by forest management.
