[nfc-l] Huge flight over NY, VT

[Kenneth V. Rosenberg]

There is s huge flight of thrushes over White Lake NY and Bennington VT tonight 
- I counted 300 plus thrushes in 30 minutes of nearly continuous layered 
calling. Mostly Swainsons but quite a few Gray-cheeked. All of which got 
flagged. Also 3 Am Bitterns

Re: [nfc-l] Interesting Calls

[Jerald]

I have had a few interesting calls this week as well. They sound rather
thrush-like, but don't match any of the thrushes. I'm guessing they're
Rose-breasted Grosbeak, but I would appreciate confirmation.

Thank you for the input. Alas, I have yet to find a way to extend the 
recordings, which has annoyed me very much as well. From,

RE: [nfc-l] Interesting Calls

[John Kearney]

Hi Preston,

Here’s my take on them.

2.54.06- Palm Warbler

2.54.07-Ovenbird

3.27.37-Indistinct call-Unknown

3.28.58-Also indistinct, looks like a “Double-up Warbler”- maybe Black-throated 
Green Warbler

[nfc-l] Big Double-up

[Bill Evans]

Dear NFCers,
My colleague Manuel Grosselet and I recorded an unidentified night flight call 
in southern Mexico (near Minatitlan) in fall 2012.  We call it “the big 
double-up” for obvious reasons as one can see in the attached spectrograms. We 
recorded 32 of the calls near Minatitlan from Oct 16-Dec 3, 2012.  What 
distinguishes it from other “double-ups” one commonly encounters in eastern US 
is the combination of the call’s broad frequency expanse (~5 kHz on average), 
the relatively large maximum frequency gap between its component tones (~ 2 kHz 
on average), and its much longer overall duration, ~85 mS on average, which is 
roughly twice as long as the Tennessee, Orange-crowned, Nashville , and 
Black-throated Green double-up complex.
Based on my not seeing this call type in 25+ years of spectrographic night 
flight call study across eastern US, I conclude that it is a species that does 
not likely migrate across eastern US.  To support this contention, I’m 
soliciting feedback from the untamed multitude of others monitoring nfcs these 
days as to whether you have encountered this big double-up call type in the 
eastern US, or anywhere in North America.  A short audio clip of the call is 
also attached.   Many thanks,  Bill Evans

[nfc-l] Linking sister birding clubs to protect neotropical migrants

[Jody W Enck]

HI All,

With such an interest in listening to migrating birds at night, I thought you’d 
all be interested in this effort.


 The Cayuga Bird Club in Ithaca, NY has started an effort to establish a 
network of sister birding clubs in North and Central America linking the 
migratory pathways of neotropical songbirds.  Many of the colorful and familiar 
"Birds of Summer" that we enjoy so much in North America during the breeding 
season (e.g., think Wood Thrush and Golden-winged Warbler) are experiencing big 
decreases in their populations.  Among many factors are loss of habitat on the 
breeding and wintering areas.  While those of us in North America are aware of 
the general population declines for many neotropical migrants, Birding clubs in 
Central America are more aware and knowledgeable of the situation on the ground 
in their countries. Some of the benefits of establishing sister birding clubs 
is to share information, pictures, and stories with each other about what the 
habitat threats and situations are like, and what people on the "other end" of 
the migratory pathway can do or need help doing.



 As president of the Cayuga Bird Club, I have contacted many birding clubs 
and Audubon Society chapters in NY and PA about the idea, and interest here in 
North America is high.  I will be traveling to Honduras later this fall to 
participate in the Honduras Birding Tour for Conservation (HBTC).  The HBTC is 
an effort to bring awareness to both the plight of birds in Honduras as well as 
the opportunities for tourists to experience the amazing bird life of that 
Central American country.  I also plan to meet with as many of the six existing 
birding clubs in Honduras as possible to discuss the sister birding club idea.  
He have made contacts with someone from most of those clubs, which are 
scattered around a country the size of Virginia.  Lacking any professional or 
institutional support for this effort, I have started a Go Fund Me campaign 
(www.gofundme.com/2rha68nv) to raise funds to 
support my travel within Honduras to visit these clubs.



 Please consider making a donation to support this effort (even $5 or $10 
donations can help!).  Also, please contact me by email at 
presid...@cayugabirdclub.org if you are interested in knowing more about this 
effort or want to help in some other way.



Thanks so much!


Jody W. Enck, PhD
Conservation Social Scientist, and
President of the Cayuga Bird Club

[nfc-l] Nocturnal migration for 3rd Week of September

[John Kearney]

Hi All,

I've posted my summary for this week's recordings on my website:
http://www.johnfkearney.com/Carleton_YarmouthCounty_2016.html.

Migration in southwest Nova Scotia was non-existent to moderate with
unsettled weather in the middle of the week. Common Yellowthroats were the
dominant species among the birds that were moving.
