Interesting Bird Observations and Fall
Hawk Watch News:
Jon
Kauffman discussed his recent
discovery of Barn Owl nestlings and 2 eggs in the nest boxes at
farms in the
Milroy area. This is unusual for this time of year; only about
10% of Barn Owls
have 2 broods/yr and these are typically in the southeast
Piedmont area of PA. Milroy
may be a uniquely favorable habitat for Barn Owl success thanks
to the land
management and farming practices of the Amish who live in the
Milroy area.
Hawk watch
locations are seeing the
seasonal sift in species heading south, especially increased
numbers of Sharp-shinned
and Red-tailed Hawks passing through in October as compared to
earlier in the
season. Other species such as Northern Harriers, Red-shouldered
Hawks and
Golden Eagles are starting to be seen more frequently as the
season progresses.
Of particular note; more than 1000 Turkey Vultures have been
seen migrating
past the Bald Eagle Mountain Hawk Watch. This is three times
more than have
been seen to date from either the Jacks or Stone Mountain watch
locations.
Old Business:
A call has
been made for volunteers
to help with a variety of Bird Club activities. If you are
willing to help or
have ideas, please contact Doug Wentzel at: djw105@psu.edu
· The State College Bird Checklist needs
to be updated to
reflect current taxonomy and to replenish the dwindling supply
of paper
checklists. SCBC could partner with other organizations such as
Millbrook Marsh
to print and distribute new checklists. Help is needed with the
checklist
itself, partnering with other organizations and printing.
· Interested in being an event coordinator
for our May
potluck? Ideas such as a photo contest at the potluck were
mentioned previously.
Any ideas or help are welcome.
· Anyone interested in leading bird walks
at Millbrook
Marsh Nature Center?
· Anyone interested in helping SCBC with FaceBook
presence?
· We need help with a SCBC membership survey
regarding our
meeting venue, field trips, other ideas.
Speaker:
Tessa Rhinehart, "Eaves
Dropping on Birds; remote recoding and artificial intelligence
for biodiversity
surveys".
Tessa described
her work as a computer programmer in the University of
Pittsburgh, Biological
Sciences Dept. (Dr. Kitzes lab) to develop a computer program
that can
recognize bird songs. A
large number of
“AudioMoth” acoustic recorders were placed in Sproul State
Forest, to record
bird songs of the dawn chorus, generating a vast amount of audio
data. To
analyze this audio data, algorithms are being developed to
“teach” the
computer, through machine learning, to recognize spectrogram
images of bird
songs of various species. The
goal is to
develop a computer program that can quickly and accurately
recognize bird songs
and calls. Methods are also being developed to pinpoint the
locations of individual
birds within an area through the use of audio data. The use of this “big
data” can increase
understanding of biodiversity, providing conservationists,
ecologist and
ornithologist with valuable information needed to benefit
species conservation.
Other research assisted by this type of audio recognition
includes comparing
bird species diversity under various land management practices
in prairie
habitats, species determination from nocturnal flight calls,
frog populations
in variously sized forest fragments and wolf pack distribution
in Washington
state.
