Berwyn Heights, MD Wood Stork photos (05/25/2011)

MD Osprey:

On Thursday evening I received a written report and two very clear photos of a Wood Stork flying over Berwyn Heights, MD (Prince George's County), seen on 5/25/2011 around 9:40 am.

The bird was seen soaring fairly high up in the thermals with Turkey Vultures and was observed for about 20 minutes. The observer is a professional wildlife biologist and is familiar from the species from Florida.

I checked Google Earth and the location where it was seen is less than 1/2 mile NNE of Lake Artemesia and about 1.6 miles SW of Greenbelt Lake.

Keep your eyes up and open ...

Phil


Liz gave me permission to post her Wood Stork photos here. Thanks, Liz!

Here are two pictures. The first is not zoomed in--it is of the stork with several vultures. The second is fairly blurry but is zoomed in on the stork alone. So exciting and unexpected!!

Washington DC checklists 1944-1946, some led by RTP

I have been canvassing historical Patuxent Wildlife Research Center (Laurel, MD) records that were retrieved from deep storage last year, to try and locate detailed write-ups of MD/DC Records Committee "reviewable" sightings. In the process of reviewing these records, I have run across some very interesting material, such as the following ...

DC Audubon Society 1944-1946 bird walk checklists including three that were led by Roger Tory Peterson.

One checklist is from an April 1946 C&O Towpath bird walk. Note that there were 70 people in tow (no pun intended, well, ... maybe so). I also found another RTP bird walk checklist from Kenilworth Aquatic Gardens (DC) on 28 May 1944 ("last walk of the season"), with an attendance of ... are you ready? ... 165 people!!! Yikes! Can you imagine the vehicles, logistics and, as someone commented, keeping them all quiet!

Peterson lived in Glen Echo, Maryland in Montgomery County from 1945 through 1953, after he got of the Army at Ft. Belvoir, VA (1942-1945).

Further down in this post, you can find the three scanned RTP DC Audubon Society checklists.

At the bottom of this post, for 33 of the DC Audubon Society checklists, I summarized the total number of species and total number of people for each bird walk, in spreadsheet format. What amazed me were: (1) the numbers of people (!) in attendance, and (2) the frequency of these trips. The number of people generally dipped into single digits when it was raining, however, at least one "rain" trip still had over 100 people!

NOTE: Personally, I find it easier to use the small "download" links BELOW the document frames to pull these PDF documents down and open them on your own computer, rather than use the on-line full screen, print, and download Scribd functions found at the top of the document frames.

Enjoy ...

[BIRDWG01] Azores Calidris

Trio_of_yanks_birdwatch_alfrey

I happened to have the issue of Birdwatch that Marshall referenced handy, so I have scanned and posted the photo. No photo editing or processing was applied.

All,

This thread reminded me of an Azores "record" that I have been curious
about for some time. The October 2006 issue of "Birdwatch" (which I
don't subscribe to, but happened across once) has a very cool article
by Peter Alfrey describing the Nearctic fallout on Corvo in October
2005 (associated with Hurricane Wilma). It included discussion of the
first Palearctic White-eyed Vireo and Hooded Warbler records, among
loads of other cool stuff (with many photos) including a massive
Chimney Swift fallout.

In that article is a color photo of a trio of Calidris, labeled: "A
trio of Yank calidrids. From left: White-rumped, Semipalmated, and
Least Sandpipers, Cabo de Praia quarry, Terceira." The photo is by
Peter Alfrey. It is an undated photo, and it is unclear to me which,
if any, record this refers to in the Azores database
( http://www.birdingazores.com/index.php?page=rarebirdref&id=549#NotFirst ).
I don't have an easy means to scan it now, but perhaps someone else
does?

It is an excellent color photo and while the White-rumped and Least
Sandpipers appear to be correctly identified, the Semipalmated looks
to me like a straightforward Little Stint based on the thin straight
bill, split supercililium, breast pattern, and overall structure. I am
curious if anyone else has seen this photo and questioned the ID, and
whether this worked its way into the official Azores records or not. I
expect someone here would have an answer, but I reach dead ends with
even trying to figure out the date on this photo.

Not that another opinion is needed on this one, but I too agree on
Semipalmated for the bird that started this thread.

Best,

Marshall

Turkey Vultures - communal bathing

The images below of communal bathing by Turkey Vultures were taken by Fallston, MD veterinarian Dr. Donald Zantop and are posted here with his permission. Searching the web, I was not able to find other images of Turkey Vultures communially engaging in this behavior.

Dr. Zantop writes, "I believe I took these in the summer of 2007. The creek is in the Fallston - Forest Hill area of Harford County Maryland and feeds in to the Gunpowder Falls. You can see this on almost any sunny day in the afternoon."

Enjoy!

Western North Atlantic albatross sighting data

version 23 as of 25 Oct 2009:

141 reports or records of 153 birds; 198 citations


Background. In 2008, a Dutch researcher queried the AOU Check-List committee regarding whether a database existed for North American/North Atlantic albatross sightings. The committee Chair happened to ask me if I knew of such a database. I was not aware of any active database and to my knowledge no albatross sighting information had been compiled or updated in at least seven years since several related articles were published in the late 1990s and early 2000s. About a year ago I had a recent need for this same information, so this request motivated me to send out a "quick" data call request to records committee contacts along the North American eastern seaboard and Gulf coast for recent albatross reports and records information. My intention was to "quickly" pull together all reports and records into a data structure. One thing led to another and, being an anal-retentive computer-type person (!), I kept probing, linking, and resolving discrepancies regarding the albatross sighting references I obtained. As I delved deeper into this task, I decided to capture all related historical details and to baseline this information for future reference.

Scope. I decided to make this a comprehensive data collection effort and pull together and summarize all published reports, records, and even anecdotal sightings. Mlodinow 1999 served as my baseline and to this I planned to add the information I received from records committee points-of-contact. Geographically, I limited this effort to eastern Canada, the eastern seaboard and Gulf coasts of the United States, and western North Atlantic islands. I included all albatross taxa, even the two historical Wandering Albatross reports from Florida. No independent detailed ornithological content analysis of the data has been undertaken at this point; record and report validity is based upon the information published, the existence of photographs, and for some later records, records committee decisions.

Data Entries. I compiled the data in an Excel workbook since filtering and sorting is more easily facilitated. The data entries are in chronological order and encompass all associated published references that I could locate. In cases where sighting reports were not accepted by state records committee, I show the submitted taxon in a red-strikeout font. I have also indicate where records committees accepted records as "albatross, sp." rather than a specific taxon.

Data Files. My most recent data compilation version is provided in the files below. Two files are provided below. [You may want to use the "download" link associated with each document frame to download the files directly to your own computer, rather than use blog's the iPaper/Scribd document capabilities.]

Summary Data File. The MS Excel summary file provides top-level statistical summaries and an abridged version of the complied western North Atlantic/Gulf of Mexico/Caribbean albatross sighting data, along with other supporting information. In the Summary Data spreadsheet file there are six worksheets (i.e., tabs) including a "Summary Data" tab ­that presents data counts by taxon by state/province, year, and month of the year. A "Quick Look" tab ­summarizes the basic information for each of the data entries. The "Negative Reports" tab indicates the states and provinces who ­indicated no albatross reports or records exist. The "Literature Cited" tab lists all published references consulted. An "Abbreviations" tab provides specialized abbreviations. The "Points-of-Contact" tab indicates contributors ­by state/province. Each worksheet is formatted for printing; worksheets can be printed individually or all together by clicking on "print entire workbook." Note that you can filter the summary data by State/Province/Territory/Island by clicking on the small pull-down triangle located in that column's header of the spreadsheet.

Detailed Data File. The MS Word document provides details for each sighting report and record. The detailed MS Word document provides published report extracts, status, and annotations for each of the report entries (some encompassing multiple birds). In the detailed document I have included extracts of relevant reference quotes. I edited these quotes (using brackets) to focus on the sighting in question; however, in some cases, multiple references could not easily be separated and in those cases I used a bold font to highlight the relevant portions of a quote. I also included editorial comments in brackets.

Referenced Literature. I have physically acquired (thanks to the help to many of you) all of the references identified, except for a few obscure ones. I found a great deal of information on the web, especially via SORA and Google Books, including various record committee reports and databases, as well as many journal and book references. The few missing references are highlighted in red. If anyone has access to any of these references, I would appreciate a copy or scan of relevant albatross quotes for my files.

Personal Communications. I included some personal communications comments from contributors. Please let me know if you think I did not capture your comments properly or if you do not wish to have your comments included in the final version. Several contributors provided views and opinions concerning sight record observer reputations; however, I generally did not include those comments in my compilation.

Feedback/Comments/Additions. I would appreciate any comments, corrections, or additional inputs. I highlighted in red font items where I am not sure of a fact or where I suspect data is missing. If contributors could especially look over the data associated with their home states, I would appreciate it. Any additional inputs (references, records committee accession numbers, specimen numbers, location specifics, other facts or comments, etc.) are also welcome.

Acknowledgements. Many thanks to all who contributed data and references to this project. I sincerely appreciate your efforts. Many of you provided specific answers to my numerous questions and tracked down and provided me with reference documents. In addition to the direct data contributors, I would also like to extend special thanks for reference document assistance to Lynda Garrett at the PWRC Library, and also to Paul O'Brien (MD/DCRC Chair), Nick Pulcinella (DOS), Marcia Watson (MD/DCRC member), and Shaibal Mitra (NY/RI). Also, thanks to all of the other key contributors including David Seeler, Denis Lepage, Norman David, Bruce Mactavish, Paul Linegar, Blake Maybank, David Christie, David Seeler, Roger Etcheberry, Bill Sheehan, Rob Woodward, Terry Bronson, Rebecca Suomala, Majorie Rines, Jeremiah Trimble, Doug Wilson, Christopher Raithel, Greg Hanisek, Angus Wilson, Jeanne Skelly, Laurie Larson, Jennifer Hanson, Bill Boyle, Frank Rohrbacher, Bruce Peterjohn, Susan Heath, Amy Gilmer, Harry LeGrand, John Wright, Jim Parnell, Donna Slyce, James F. Flynn Jr., Andy Kratter, Steve McConnell, Greg D. Jackson, Terence Schiefer, Donna Dittmann, Steven W. Cardiff, Mark Lockwood, Tony White, and Andrew Dobson.

Maryland's next species predictions

In June 2009, Maryland birders Bill Hubick and Matt Hafner conducted a poll of Maryland birders to predict Maryland's Next 10 Species. This effort was a update to a similar poll conducted in 2001 that correctly predicted seven top ten species that were subsequently found in Maryland over the ensuing eight years.
 
The document posted below summarizes my "top ten" analysis and the spreadsheets present my backup data in both ranked and taxonomic order. (Click on the small brown "download" link below each document frame to download the PDF files to your computer.)
 
My "top ten" predictions are:
 
1. Brambling
2. Garganey
3. Black-tailed Godwit
4. Bell's Vireo
5. Ivory Gull
6. Eurasian Woodcock
7.White-tailed Kite
8. Lewis's Woodpecker
9. Bar-tailed Godwit
10. White-winged Tern
11. Pink-footed Goose
12. Snowy Plover
13. Sharp-tailed Sandpiper
14. Fieldfare
15. Redwing
 
The results of the current poll can be found here ...

Phil:
Some additional information about the Booby photographs.  The bird was seen at about 10 am, Friday July 17 fairly close to the western shore of the Chesapeake off Cove Point in Calvert County.  It circled the boat and then landed and was photographed.  Lois Fussell, who saw the bird was initially not sure that it was not an immature Norther Gannet, but said it was much to small.  I think the photos speak for themselves.

 If you think it appropriate, please post this to MDOsprey.  In addition to this bird, there was another "possible" sighting last week, so birders should keep their eyes open.  I don't have a site to post the photographs, but Lois said you should feel free to do so if you want to.

 I will give Lois a form for a full report to the Records Committee, including measurements of the boat hook (?) in the first photograph so that the bird's size can be determined more accurately if necessary.

 Just got a call from Lois Fussell.  After carefull checking their "sailing log"  they concluded that they were mistaken and the Bobby was seen just below the Potomac River in Virginia waters.  She is sorry.  To whom should they send a report for the Virginia Records commitee?

 I guess Maryland birders should still keep their eyes open since the bird was within a few miles of Maryland waters and there is still a "possible" sighting in Maryland waters

Hi Stephen:
Wow! What a great photo of an immature Brown Booby. It shows all of the key field marks to eliminate other sulids ... the yellow feet and the all dark brown plumage. Rules out juvie Gannet and other Boobies such as Red-footed and Masked.

Here's a link to the VARCOM reporting web page ...

Hi Phil,

I would be happy to provide you my report.  I observed the bird in a small bay in N. Assawoman Bay approximately 0.5 miles south of DE Rt 54.  The bay is located near the southeat cul de sac of Madison Ave south of DE Rt 54.  The bird was first observed flying into the bay at approximately 8am.  I observed the bird for approximately 20 minutes before flew a short distance to a marsh northeast of the sighting.  Attached is a photo of the bird and you will also recieve an email message that includes a file you can load into Google Earth that will give you the coordinates of the exact location.
