Science Times: What wildfire smoke means for birds.

The vulnerability of birds to wildfire smoke, plus debates over the Audubon name

Welcome to a special birding edition of the Science Times newsletter, which will land in your inbox every Friday through September.

The Maui wildfires are an ongoing human tragedy. At least 111 people have died, more than 1,000 people are unaccounted for, and many have been displaced from their homes.

But such fires also put animals at risk. Wildlife, livestock and pets often perish in fires. Flames can destroy critical habitats for endangered species and set back conservation efforts. (The Hawaii fires threatened the Maui Bird Conservation Center, which is home to some of the world's most endangered birds.) And all creatures that breathe air are susceptible to smoke.

"Birds are especially vulnerable, because they have an incredibly efficient respiratory system, which is designed to deliver enough oxygen to power flight," said Olivia Sanderfoot, an ecologist at the University of California, Los Angeles, who studies how smoke affects birds and other wildlife. The avian respiratory system is especially adept at drawing oxygen out of the air, but if there are pollutants wafting around, birds take those up readily, too.

Precisely how smoke affects birds is still a nascent field of research, with many unanswered questions. But studies have shown that smoke can damage birds' lungs and make them more vulnerable to respiratory infections. And the fine particulate matter that is present in smoke — and causes well-documented health problems in humans — can also accumulate in birds' airways. "We know that air pollution, and smoke specifically, causes respiratory distress and makes it more difficult for birds to breathe," Dr. Sanderfoot said.

Plumes of smoke may also disrupt the journeys of migrating birds, many of which are under threat. In 2020, tule geese, which summer in Alaska, began their fall migrations in the middle of a record wildfire season on the West Coast. The geese needed more than double the usual time to arrive at their traditional Oregon stopover site, and their flight paths were nearly 500 miles longer, scientists found.

"We're beginning to see that birds have to make hard choices when they come across thick smoke," said Andrew Stillman, an ecologist at the Cornell Lab of Ornithology who studies how major fires affect birds.

Birds can sit and wait for the smoke to clear, which can leave them stranded for days in unfamiliar territory and delay their migration. They can fly around the smoke, making detours that extend their journeys and use up precious energy reserves. Or they can continue to fly through, gulping down smoke as they go. "Either way, the migrating birds are worse off when they finally arrive," Dr. Stillman said. "And not everybody survives that perilous journey."

Dr. Sanderfoot is exploring how smoke alters bird behavior and how those responses vary according to species and circumstance. (Some birds of prey seem to be attracted to fires, perhaps because fleeing or injured small animals make for an easy dinner.) Which species are most vulnerable to wildfires? Do birds with larger home ranges find escape easier than do those with smaller territories? Do birds that live in fire-prone areas respond differently than those inhabiting places where wildfires are a newer threat? Do responses vary at different times of year?

"And all of this work is geared toward answering questions that I hear over and over from birders in our community," Dr. Sanderfoot said. "Folks want to know what's happening to birds when it's smoky."

She is also enlisting amateur bird watchers to help her answer these questions. One new effort, called Project Phoenix, is now seeking California residents who are willing to spend 10 minutes a week observing their local birds through the fire season. Dr. Sanderfoot hopes to learn how birds alter their habitat use in response to smoke, and whether providing bird feeders and baths "could help them thrive as smoke persists on the landscape," she said. "I'm hoping to put that all together and really help us learn, from a policy standpoint, what we can do to help birds as we see more and more smoke."

Reader comments: Diversity inside Audubon

Readers responded to The Times's story about the battle within the Audubon Society over James Audubon's ties to slavery. The organization is among many caught between a desire to appeal to a younger, more diverse generation and concerns that some changes the group was considering went too far.

It's quite fascinating to me, as an older white male who donates to conservation organizations, that so many commenters are appalled at the idea of changing the name and want to focus on the important work that Audubon does rather than consider a name change. Why can't Audubon continue its important work and change its name at the same time?

— nhtimes, Boston

No social justice is being served by changing the name of the Audubon Society. Audubon created the ornithological movement in this country nearly single-handedly. His name is synonymous with it and his name now transcends him as a person. And the reason his name is on the society is for his scientific and artistic contributions to birding.

— Jeff, U.S.

Wouldn't Avian Society be a more descriptive name, especially for newcomers and younger joiners? Eventually, the name Audubon would fade from memory.

— R. Thomas Berner, Bellefonte, Pa.

USAO District of Kansas
Kansas City, Topeka, or Wichita, Kansas
Wichita, Kansas
Announcement #: 23-KS-12097009-AUSA-09
Application Deadline: September 8, 2023

Achieving and maintaining eLitigation proficiency among attorneys and staff is a top priority of the Department of Justice and the United States Attorney's Office. This Assistant United States Attorney (AUSA) will be responsible for building on and overseeing the office's eLitigation operations. This includes advising and/or consulting with the office's eLitigation support staff, civil and criminal case teams, management, and others, such as the Court, Federal Public Defender, law enforcement and client agencies, on substantive electronic litigation (eLitigation) and discovery issues, ensuring discovery processes are defensible, further developing the office's eLitigation policies and protocols, including procedures for processing, reviewing, producing, and managing electronic discovery, coordinating litigation support work, and providing training on litigation technology software tools and applications. This is not a trial AUSA position; it does not involve case handling or routine litigation. The selected candidate is an attorney advisor, who will be fully dedicated to coordinating the office's eLitigation program. The AUSA will be located in the District of Kansas and will be assigned to work in one of our three office locations: Kansas City, Topeka, or Wichita, Kansas based on the applicant's preference.

Responsibilities will increase and assignments will become more complex as your training and experience progress.

USAO District of Columbia
United States Attorney's Office for the District of Columbia
Washington, District of Columbia

Application Deadline: October 10, 2023

Responsibilities and Opportunities Offered: The U.S. Attorney's Office in Washington, D.C. has openings for its Special AUSA (SAUSA) detail program starting on October 10, 2023, with other details starting on January 16, 2024, and April 8, 2024.

SEVEN MONTH DETAIL

The first option is a detail that will start on October 10, 2023, and end on May 3, 2024.  The detail begins with the same three-week Basic Training course that our newly-hired AUSAs attend.  The course is an excellent blend of intense academic classes (e.g., evidence, discovery), trial skills, and hands-on experience, including evidence workshops and mock trials that are critiqued by seasoned Assistant United States Attorneys with years of trial experience.  At the conclusion of Basic Training, SAUSAs are assigned to either our Misdemeanor Section or our Domestic Violence Misdemeanor Section in the Superior Court Division.  While in the Superior Court Division, SAUSAs will handle their own caseloads; draft and argue motions; handle plea negotiations; conduct plea hearings; meet with and prepare victims and witnesses; first-chair bench trials; advocate at sentencings; etc.  Most days include court appearances.  There is no difference between a regular AUSA and a SAUSA in terms of duties, responsibilities, and training.  Because the U.S. Attorney's Office also serves as the local prosecutor for the District, we prosecute thousands of cases each year.  Our misdemeanor-level caseloads include simple assaults; threats; possession of prohibited weapons; drug possession; assaults on police officers; theft; destruction of property; hate/bias crimes; child abuse; credit card fraud; etc.  We do not handle traffic; DUI; or juvenile cases. 

Second Portion of Detail:  During the second portion of the detail (January 16, 2024 – May 3, 2024), the SAUSA will be given more advanced litigation opportunities while in their assigned Misdemeanor or DV Section.  Alternatively, with advance agreement between the USAO-DC and the SAUSA and his/her agency, the SAUSA may spend the second portion of the detail in the USAO-DC's criminal Appellate Division, criminal Special Proceedings Division, or Civil Division.  DOJ attorneys are eligible to be considered for an additional six-month detail in the Criminal Division, which requires the approval of the Chief of the Criminal Division and the requisite security clearance.

SHORTENED DETAIL

The second option is a shorter detail (4 months) in the Superior Court Division that will start on October 10, 2023, and end on February 9, 2024. This program begins the same way as the seven-month detail with our Basic Training program followed by assignments to either our Misdemeanor Section or our Domestic Violence Misdemeanor Section.  While SAUSAs in the shortened detail will receive the same training and handle the same types of cases as the SAUSAs in the seven-month detail, the more advanced litigation opportunities are not part of this program.                                                                                                                   

Finally, although we have flexibility in terms of when SAUSAs start, all SAUSAs (and regular AUSAs) go through our Basic Training program before handling cases.  We have classes that begin on October 10, 2023, January 16, 2024, and April 8, 2024.  If a SAUSA starts before a Basic Training class, he or she will assist with case processing/intake; shadow other attorneys; draft motions, etc. until the class starts, but the end date of the detail would remain the same.
