Letter from the President

A profile of DOS President Mike Moore.I have written here several times that I love birding during fall migration because it is “rarity season” when many very unusual birds show up. This promise was finally fulfilled when our own Andy Ednie found a probable Tropical Kingbird at Thousand Acre Marsh this week. This species is very rare on the east coast and has only been seen three times in Delaware before. Unfortunately, it was only seen by one other birder, but it may still be around. Worth looking for if you have time – drive slowly scanning telephone wires.
The Ashland Hawk Watch has produced a bird many people look for – Evening Grosbeaks. There have been several around the bird blind and Hawk Watch Hill the last couple of days. Of course, Ashland is in the middle of Golden Eagle season and has already recorded three of these sought-after rarities. Not be outdone, Cape Henlopen Hawk Watch recorded a Northern Goshawk, a species that has become very rare in Delaware in recent years, in addition to a couple of Golden Eagles of its own.
We had the first in-person members meeting in October at Ashland Nature Center and were treated to a great talk by Holly Merker on Ornitherapy. About 40 people attended. Next month we have a special treat. Matt Halley will be giving his talk in the newly remodeled Delaware Museum of Nature and Science. If you have not seen it since the remodel, it has been completely reimagined and it should be a quite a treat. I hope to see you there.
I hope to see you in the field. If I do and I don’t know you, please come up and introduce yourself as a DOS member.

November 16 Meeting:
Matt Halley

“New and overlooked sources in the history of American Ornithology”

November 16 @ 7:00 pm – 9:00 pm EDT

Matthew R. Halley is the Assistant Curator of Birds at the Delaware Museum of Natural History. Dr. Halley received his doctorate in environmental science from Drexel University and the Academy of Natural Sciences of Drexel University, where he primarily studied the systematics of the nightingale-thrushes (genus Catharus) and the evolution of seasonal migration. His field research spans a wide range of countries including Panama, Venezuela, Nicaragua, India, Israel, Canada, and the United States.

Dr. Halley’s interdisciplinary research focuses primarily on the systematics and social evolution of American birds, as well as analysis and reinterpretation of the work of historical American scientists from the 18th and 19th centuries. His research utilizes many different technologies including genetics, video cameras, tracking devices, and analysis of audio recordings and museum specimens. In addition to being a historian and scientist, Dr. Halley is also a lifelong musician and featured on numerous albums, including his own self-titled album Matthew Halley (2020). His broad expertise in history, science, and art allows him to continually contribute to the research of a wide multitude of subjects.

Matthew is currently the Vice President and Program Chair for DOS.

This meeting will be in-person at the
 Delaware Museum of Nature & Science.

Admission is free, and exhibits will be open.

Conservation Update

Horseshoe crabs on beach. Creative Commons from Wikipedia.

In recent shorebird-related news, the Atlantic States Marine Fisheries Commission (ASMFC) is proposing to alter horseshoe crab harvest restrictions and include female horseshoe crabs in future harvests.

The DOS Conservation Committee has been tracking this issue closely and has significant concerns about the adoption of the ASMFC’s Revised Adaptive Resource Management (ARM) model to set harvest quotas for horseshoe crab harvest. DOS does not support the adoption of a model that would currently recommend harvest of female crabs at this point in the recovery trajectory of rufa Red Knots.

We have submitted a letter recommending that ASMFC should NOT adopt the Addendum to the HSC Fisheries Management Plan at this time. This detailed letter is available on the website here.

He spent many months across a four year period gathering the recordings to produce this audio journey.

Dave Ross recently passed away on 30 September 2022. His passionate 35-year audio career lives on in perpetuity via thousands of archived recordings in the Macaulay Library.
