Bird Club Field Trips: (Susan Smith)
Thank you to Susan for scheduling a variety of interesting field
trips this spring. And with the bird walks sponsored by Millbrook
Marsh and Penn State Arboretum that are also co-led by SCBC
members, we have more opportunities than ever to get out and enjoy
our avian neighbors. Details for SCBC trips can be found on our
website www.scbirdcl.org
Announcements/Other Activities:
The PSO activity led by Chad Kauffman to bird under-birded
counties will take place this coming weekend, April 28-30 in Greene
County. For more information contact Chad.
PSO’s Birding Festival will be held May 19-21 here in
State College. Field trip spots are filling fast, so register
soon. For details see https://pabirds.org/BirdingFestival/BF.php
Birding Cup is coming up May 5-6. You can register as a
team competing in central PA for a variety of categories or
collaboratively as a “global participant” from anywhere in the
world (including PA). This year’s donations will support the Chuck
Widmann Endowment for Citizen Science which funds the official
hawk counter on Tussey Mountain each spring. For details see: https://www.shaverscreek.org/public-programs-and-events/birding-cup/
Today was the final day of counting at the Tussey Mountain
hawk watch. Andrew Bechdel, our official counter reflected
on his time on the mountain this spring. He not only honed his
identification skills, but also gained a deeper appreciation of
the art of observation; slowing down to really study behaviors and
antics of all the birds he encountered.
Nick Kerlin banded over 400 purple martins in central PA
last year with aluminum as well as orange and yellow bands to
study distribution of this species in our region. He is requesting
that everyone keep an eye out for purple martins and take note of
any banded birds. Contact Nick with date, location and number of
birds, band color sequence and which leg is banded by emailing: Nick
Greg Grove updated us on the latest news in the years’ long saga
of Old Crow Wetland and the proposed Rutter’s truck stop
which would have 7 acres of paved surface and diesel fueling for
18-wheelers that would be placed upstream and within inches of the
wetland. On Wednesday, May 3 at 6:30, DEP is holding a very
important public meeting at the Smithfield township building. This
meeting is a chance to show DEP that opposition to this project is
strong and widespread. Greg urged as many people as possible to
attend - numbers may matter a lot. Those interested in verbally
expressing their opposition will be given a brief time to speak.
Please notify John
Repetz by 4 pm May 2, if you wish to speak at the meeting.
Additionally, written comments are also still accepted (even if
you have done so previously) - email by May 18 to: Scott
Williamson; Nathan
Phillips; Andrea
Blosser. Joe will be going to the meeting and has space for
several others if you are interested in carpooling.
The State College local government has designated May 13 as Migratory
Bird
Day and Lights-Out event. Joe encouraged everyone to
register to make a pledge to turn off any unnecessary outdoor
lighting on the night of May 12-13 and to pass the word to friends
and neighbors, even if you live outside of State College Borough.
Birds are attracted to light during night migration. On PSU campus
this has recently resulted in bird collisions with buildings,
killing 500+ individuals representing 70 species of birds. See

Notable Bird Sightings: Greg Grove’s Summary
(March 23-April 26, 2023; Centre and its contiguous counties)
The vast majority of tundra swans have already passed through our
area so there is a possibility that swans seen now are Trumpeter
swans. Four sightings of trumpeters have been confirmed recently.
Other unusual waterfowl include surf and black scoters and a
red-necked grebe as well as very large numbers of ring-necked
ducks including a single large gathering of 467. A few common
gallinules, Caspian terns and American bittern have been seen as
well as heard on night flight call recordings. Other sightings
include a few sandhill cranes, American avocet, glossy ibis and in
the grassland of Sandy Ridge, Clearfield Co., upland plover that
may be breeding there.
Barn Owls at 3 locations have been documented by Jon Kaufman. Red
crossbills and clay-colored sparrows have been reported. To date,
21 of the 35 species of warblers that arrive or move through our
area have been reported including orange-crowned warbler. An
unusually early report of Louisiana waterthrush was given on March
19. Reports of rose-breasted grosbeaks and indigo bunting have
been trickling in over the past few days.
Speaker: Zoey Greenberg: “More Than Just a Pretty Face: Why
Vultures Deserve a Second Look”

Many of us know Zoey from her time at Shaver’s Creek and as our
official Tussey mountain hawk counter during spring 2020. Zoey has
broad experience with both black and turkey vultures. Her first
in-depth encounters with these 2 species were at Shaver’s Creek
where she helped care for and train them for use in educational
programs. She continued studying and writing about vultures at
Hawk Mountain Sanctuary and beyond.
Zoey discussed the fact that for the general public, especially in
western cultures, vultures elicit a less than positive response.
They are not particularly attractive or cute and their lifestyle
as obligate scavengers is off-putting to many people. In other
parts of the world, vultures are viewed as purifiers and a link
between the living and dead.
But vultures do have an incredibly important role to play in the
ecosystem by quickly dispatching carcasses that would otherwise
remain in the environment presenting greater dangers. Using the
example of exploding incidents of rabies among the human
population in Asia and Africa, Zoey described the importance of
vultures’ contribution to environmental and human health. Old
World vulture populations plummeted due to the use of the
anti-inflammatory drug, Diclofenac, in cattle. Vultures are killed
by the drug when they consume cow carcasses. With no vultures,
that role was filled by wild dogs whose populations increased as
did bites to humans by rabid dogs resulting in astronomical
increases in medical expenses.
Zoey discussed the classification of vultures as raptors. There
are 23 species, 16 old world and 7 New World. The Old World
vultures are not related to new world vultures, but rather these 2
groups evolved separately through convergent evolution. Both Old
and New World vultures share adaptive characteristics such as
large crops, efficient soaring flight and visual cues to locate
carcasses.
Because vultures consume carcasses that are in a state of
decomposition, their digestive systems are designed to handle the
many otherwise harmful substances produced by microbial
decomposers such as botulism and anthrax. Other behaviors such as
urohidrosis (peeing on their legs) may help keep microbes at bay,
though this requires further study.
Zoey focused most of her discussion on our 2 common new world
vultures, black and turkey. Distinguishing features between the 2
species include the turkey vultures’ (TV) distinctive dihedral
(V-shape) formed by their out-stretched wings as they soar and the
silver lining at the back half of their underwing. The underwing
of black vultures (BV) have white patches at the tips.
Having the best sense of smell of any avian species, TVs use this
ability to locate food. BVs follow TVs since their ability to
smell is not nearly as good.
TVs are one of the longest distance raptor migrants especially
populations that breed in central Canada and the west coast which
winter in central and South America. East coast populations
migrate to warmer locations along the eastern seaboard.
BVs tend to be highly social, maintaining family aggregation long
after fledging. Family cohesion can last for years and they share
behaviors, learning from other members of the group. Zoey showed
us a video of BVs in South America picking parasites off of
Capybara. This mutually beneficial behavior gives the BV’s a meal
and rids the Capybara of parasites.
Though they are scavengers, BV have been reported on occasion to
kill weak dying animals. In the Midwest, BV’s have a bad
reputation due to a few highly publicized incidents of killing
livestock. Studies to determine the extent of this issue and to
mitigate human/vulture conflict are ongoing.
Other new world vulture species are found mainly in Central and
South America. These include king, greater and lesser yellow
headed vultures and Andean and California condors. Lesser yellow
headed vultures are found only in wetlands and are one of the only
vultures known to primarily take live prey, mainly rodents and
reptiles. King vultures, with their large powerful beaks, are able
to rip open tough hides. Arriving first at the carcass, they
provide access for all of the other scavengers.
Currently in the US, we have robust populations of TV’s and BV’s.
California Condors historically survived largely on whale
carcasses beached on the west coast. The demise of whale
populations, DDT and especially lead poisoning decimated their
populations. Once precipitously on the brink of extinction, they
were making a comeback thanks to extraordinary efforts during the
last 40 years.
Until a few months ago, lead poisoning was the greatest threat to
California condors. Every condor has some level of lead in their
system and condors are one of the more lead-sensitive species.
Licensed hunters in their range tend to comply with lead
ammunition restrictions, but vermin hunting poses the risk. Within
the last few months, avian flu has presented a huge risk to the
existing small population. Already 20 CA condors have died this
month, 10 of those confirmed from avian flu.
Proactive conservation is necessary, not just when a species is on
the brink, but when populations are stable and seemingly robust.
To ensure the health of vulture populations, there needs to be a
change in the collective conscientiousness around vultures as a
group worthy of conservation, certainly for the ecosystem services
they provide, even if their facial appearance and lifestyle are
less appealing to some.
