Re: SEG Environmental Chandeleur Islands Trip 23 April 2024
Wish I had been there! Off topic, but I noticed that a few photos were uploaded to the wrong species. Jennifer Coulson Pearl River, LA On Wed, Apr 24, 2024 at 9:01?PM Johnson, Erik via groups.io <Erik.Johnson= [email protected]> wrote: LAbird,
I looked up cuckoo continental population estimates in the Partners in

About 8.4 million Yellow-billed Cuckoos in the U.S. and Canada versus about
0.9 million Black-billed Cuckoos, or a 10:1 ratio.

So why the 100:1 ratio detected in migration per Van (I'm inclined to
agree with that). Interesting that with a low sample, Robb got more of a
10:1 ratio in nocturnal flight - would be interesting to know how that
stacks up across a season, or multiple seasons.
In the eBird weekly abundance maps, Black-billed Cuckoo all but disappears
in migration.
My hunch is that Black-billed Cuckoo is more of a long-distance jumper
than Yellow-billed Cuckoo, which may be better described as a
short-distance skipper. The corollary is that Black-billed would pass
through faster, thus is less available for detection.
An alternative (or contributing factor) is that Black-bills are a lot less
easy to detect, but I just don't believe that Yellow-billed Cuckoo is 10x
as likely to be detected as a Black-billed. Black-bills do seem to be a lot
less vocal, however, so maybe that's some of it.
Someone needs to do a migration tracking study on Black-billed Cuckoos!
Only 3 Motus tags ever deployed, and no other tracking information seems to
be published.
Happy migration!

From my nocturnal flight call station in Baton Rouge the evening of April
22nd was a season high for migrating cuckoos. Between 9:30 pm and 3:30 am
(April 23rd) I had 24 individual yellow-billed and 2 black-billed.

2024 Jack et al. ¡ª wow, what an experience! Fascinating.
As for the cuckoo prevalence ¡. Another hypothesis is that it was just one
of those ¡°cuckoo waves¡±. Spring waves are often dominated by one taxonomic
category. For example, sometimes there are ¡°cardinaline days" with
buntings, grosbeaks, and Dickcissels making up the bulk of the migrants.
Rarely there are ¡°thrush days, with Catharus species and Wood Thrush
predominating. Sometimes warblers steal the show. Sometimes Catbirds or
R-e Vireos are way over-represented.
As fo YB vs. BB cuckoos ¡ª indeed it¡¯s pretty clear that YB is a common
bird with a huge overall population, and BB is generally scarce. Although
YB has a larger breeding distribution, the difference is small compared to
the ratio of migrants detected, which I suspect is at least 100:1. Why the
disparity is so great is a mystery to me and to my buddies with whom I¡¯ve
discussed this on long birding trips. My personal high count for BB is 5,
way back in April 1979, and nowadays, seeing more than 1 in day is a big
deal. There have been years when I¡¯ve not seen one at all.

I hope you all have been having a birdy spring! Hopefully we get one
more front before the end of the month--these south winds have been
killing me!
I wanted to write to talk about the crazy day on the Chandeleurs that
we had yesterday. As part of an ongoing survey by SEG Environmental,
we bird the island once a month looking to assess the numbers of
several target species (Red Knot, Chandeleur Gull, Wilson's/Piping/Snowy Plovers, etc.).
I think that we have all been most excited for the April survey, and
it definitely lived up to expectations.
For those that have not had the pleasure of visiting the Chandeleurs,
it is an amazing place. Most (I would estimate over 90%) of the
island's vegetation is Saltmarsh Cordgrass (Spartina alterniflora); in
some of the slightly higher elevation areas, there is also Phragmites
and Groundsel as well. Matt Conn and I surveyed the northern tip of
Chandeleur Island, which has almost no vegetation except for Spartina.
The birding was nothing short of excellent-we had 81 species (+1
Chandeleur Gull), which I think is pretty great considering there is
only 1 tree in that section (a 6 ft tall Mangrove). There were about
7 small mounds in the saltmarsh that had small groundsel bushes or
Phragmites stands. Each bush or stand of Phragmites was astoundingly
full of migrants. Take a look at our eBird checklist here
<<
70012706>> for the full rundown. My personal highlight was the best
Black-billed Cuckoo looks I can ask for! I know several other groups
had great birds as well: Cape May Warbler (x2), Yellow Rail (!!), and Blackpoll Warblers were seen by other surveyors on their more southerly
transects.
I was most interested by the incredible density of Cuckoos compared to
smaller migrants (e.g. warblers, buntings, etc). The only thing I can
think of is that there is really nothing for cuckoos to eat on the
islands:
there is no fruit, no insects much larger than saltmarsh moths or
horseflies, nothing that Cuckoos could theoretically refuel themselves
with after a trans-Gulf flight. Whereas there are plenty of tiny
insects (aphids, mosquitos, miniscule beetles and saltmarsh flies) for
warblers to eat, and plenty of seeds for INBUs etc. I also found the
ratio of Yellow- to Black-billed Cuckoos interesting. I believe that
Matt and I had a 100% detection rate of Cuckoos within our section,
and am pretty positive in a 100% correct identification rate as well.
I have always thought that my lack of mainland BB Cuckoos was a
detection error, but now I am wondering if it is more of a disparity in population sizes.
I wrote this in my eBird comments, but this was really one of the most
exciting days of birding in my life. Small groundsel bushes (2 feet
high with a diameter of 18 inches) were holding ridiculous totals of
birds such as one that held 7 Y-b Cuckoos, 3 Catbirds, 2 Ovenbirds, 1
Swainson's Thrush, and 2 Yellow Warblers. An absolutely incredible
experience, and just wanted to share that with you all.

I put together another video from a different dish. This one is Dish 3, and
is in the open woods behind the mister and water hole dishes. The woods in
view behind the dish include a travel lane for many animals not often seen
in the sanctuary. I spare you a full 20 minute visit by a roaming group of

SEG Environmental Chandeleur Islands Trip 23 April 2024
LaBird
I hope you all have been having a birdy spring! Hopefully we get one more
front before the end of the month--these south winds have been killing me!
I wanted to write to talk about the crazy day on the Chandeleurs that we
had yesterday. As part of an ongoing survey by SEG Environmental, we bird
the island once a month looking to assess the numbers of several target
species (Red Knot, Chandeleur Gull, Wilson's/Piping/Snowy Plovers, etc.).
I think that we have all been most excited for the April survey, and it
definitely lived up to expectations.
For those that have not had the pleasure of visiting the Chandeleurs, it is
an amazing place. Most (I would estimate over 90%) of the island's
vegetation is Saltmarsh Cordgrass (Spartina alterniflora); in some of the
slightly higher elevation areas, there is also Phragmites and Groundsel as
well. Matt Conn and I surveyed the northern tip of Chandeleur Island,
which has almost no vegetation except for Spartina. The birding was
nothing short of excellent-we had 81 species (+1 Chandeleur Gull), which I
think is pretty great considering there is only 1 tree in that section (a 6
ft tall Mangrove). There were about 7 small mounds in the saltmarsh that
had small groundsel bushes or Phragmites stands. Each bush or stand of
Phragmites was astoundingly full of migrants. Take a look at our eBird
checklist here <> for the full
rundown. My personal highlight was the best Black-billed Cuckoo looks I
can ask for! I know several other groups had great birds as well: Cape May
Warbler (x2), Yellow Rail (!!), and Blackpoll Warblers were seen by other
surveyors on their more southerly transects.
I was most interested by the incredible density of Cuckoos compared to
smaller migrants (e.g. warblers, buntings, etc). The only thing I can
think of is that there is really nothing for cuckoos to eat on the islands:
there is no fruit, no insects much larger than saltmarsh moths or
horseflies, nothing that Cuckoos could theoretically refuel themselves with
after a trans-Gulf flight. Whereas there are plenty of tiny insects
(aphids, mosquitos, miniscule beetles and saltmarsh flies) for warblers to
eat, and plenty of seeds for INBUs etc. I also found the ratio of Yellow-
to Black-billed Cuckoos interesting. I believe that Matt and I had a 100%
detection rate of Cuckoos within our section, and am pretty positive in a
100% correct identification rate as well. I have always thought that my
lack of mainland BB Cuckoos was a detection error, but now I am wondering
if it is more of a disparity in population sizes.
I wrote this in my eBird comments, but this was really one of the most
exciting days of birding in my life. Small groundsel bushes (2 feet high
with a diameter of 18 inches) were holding ridiculous totals of birds such
as one that held 7 Y-b Cuckoos, 3 Catbirds, 2 Ovenbirds, 1 Swainson's
Thrush, and 2 Yellow Warblers. An absolutely incredible experience, and
just wanted to share that with you all.
Thanks for reading this monologue and good birding to y'all,
Jack Rogers

Viewing this and others I will post should be free viewing to the public.
You would pay if you want to create an account and upload your videos. This
video is made up of fifty-five, 5 second clips. The camera recorded 710
clips activated by motion over this time period. Lots of Grackles and
Catbirds. I edited them together into one video and it does jump from one
to the next. If I get better with video editing, I will work on
transitions. I think you have a slide bar to pause and advance forward and
back, but I am not sure exactly what the public view is. I suspect the
video quality and playback will vary with internet connection and playback
device. It can be expanded to full screen which looks pretty good on my
monitor.

LABIRD,
Many of you have supported the Minden High School Nature Club over the years, and we desperately need your support now.
The 6th Annual Minden High School Nature Club¡¯s Bird-a-thon fundraiser is this Sunday, 28 April. Two club members will assist me with a Birding Big Day in Claiborne Parish to document as many species as possible. You can pledge an amount per species or make a donation outright.
Will you help the club meet its pledge goals?
Currently, we are about $3000 below our goal of meeting last year¡¯s total! Every pledge or donation makes a HUGE difference!
Your money isn¡¯t wasted! Each year, we give a deserving, graduating senior club member a $1000 college scholarship!
It takes about $195 to cover the cost of one student to go to our four-day trip to Petit Jean State Park. $220 for a student to go on our four-day trip to Southwest Louisiana.
A pledge of 50 cents or a dollar per species from a few more people helps these kids tremendously!
If you¡¯re able to help, please reply with a pledge amount or donation amount. I¡¯ll send you the mailing address for a check payment, or you can Venmo me if you prefer.
Thank you so much!!
John Dillon
