Rodenticides are a deadly, and in many places, growing problem for both predators and scavengers. A study out today in the Journal of Raptor Research shows that even after a statewide ban (with a huge agricultural exemption) on anticoagulant rat poison in California, turkey vultures are still being exposed. Important not only for the vultures themselves, but for other species that are harder to monitor, including endangered condors.

Allen PressTurkey Vultures (Cathartes aura) from Southern California are Exposed to Anticoagulant Rodenticides Despite Recent BansABSTRACT. Secondary poisoning with anticoagulant rodenticides (ARs) has been identified as an important threat for raptor conservation worldwide. In 2019, the California State Legislature passed Assembly Bill 1788 (made effective in 2020), which prohibits or limits the use of second-generation anticoagulant rodenticides (SGARs) in the state, as a follow-up to the California Department of Pesticide Regulation’s ban on SGARS implemented in 2014. Currently, the adherence to these recent restrictions on ARs in southern California is unknown. To assess whether these bans prevented exposure of raptors and other wildlife to ARs, we investigated (1) the prevalence of exposure to eight different ARs in the blood of Turkey Vultures (Cathartes aura) before and after the 2019 ban, and (2) the distribution of resighted (encountered) wing-tagged Turkey Vultures included in this study to assess where exposure might occur. Of 27 Turkey Vultures tested for eight ARs, one out of 11 sampled in 2017 had detectable (trace) but not quantifiable levels of difethialone, and two out of 16 (12.5%) sampled in 2021 had detectable levels of diphacinone (one had 8 ppb; another indicated as positive without quantification). Overall, the prevalence of exposure to ARs was 11.1% (3 of 27), 7.4% for diphacinone and 3.7% for difethialone. Based on 93 resightings of 20 of the wing-tagged Turkey Vultures, all but one remained within the areas of Los Angeles, San Bernardino, Orange, Riverside, and San Diego Counties of southern California. Our study suggests that the exposure risk of Turkey Vultures to ARs persisted despite recent restrictions. Our small sample size and reliance on blood in live vultures rather than liver tissue in dead ones may be underestimating true ARs exposure in our study population. We propose a continued and integrated monitoring approach that includes measurements of ARs in both free-ranging (blood samples) and deceased (liver samples) Turkey Vultures for effective large-scale monitoring. This approach will assess compliance with current and future bans and regulations regarding the use of these poisons in California.

Cautiously optimistic news for Cinereous vultures in Portugal. Two years into a monitoring project, both nests and breeding success are up.

Vulture Conservation Foundation · Cinereous vulture increases to more than 108 nesting pairs in Portugal - Vulture Conservation FoundationThe LIFE Aegypius Return project closes its second breeding season with optimism.  The LIFE Aegypius Return project began with the aim of doubling the breeding population of the Cinereous Vulture (Aegypius monachus) in Portugal, which in 2022 totalled around 40 pairs in four colonies. In 2024, the project recorded 108 to 116 nesting pairs, which […]

#Vultures are good.

A "culture vulture" would be someone who takes a cultural meme or item that is either unneeded or harmful, and makes into something new and useful. Like a great cover of a forgotten song.

A "vulture capitalist" would be someone who runs a truly circular business, making money by reducing waste and making a cleaner, safer world.

I will rest and stop posting forever when these terms are compliments, and not before.

I would 100% make a visit to Makanda, Illinois for their annual Vulture Fest, an arts and music festival that also celebrates the arrival of migrating vultures into the area. I hope I'm in the Midwest in October sometime, because not many towns have vulture-themed festivals, and I want to give them money for it.

The Yurok Tribe's wildlife office has announced that the last two California Condor releases of 2024 have been successful. A8 and A9 are both young males, and were both hatched and raised at the Oregon Zoo in Portland.

These two make 18 total Prey-go-neesh (their Yurok name) in the skies over Yurok land.

The tribe's IG post has more details: instagram.com/p/DAuMTYqSHu3/?i

InstagramYurok Tribe on Instagram: "The last of this year’s condor cohort have been released! A8 (California Condor Recovery Program Studbook ID 1117) and A9 (Studbook 1126) took flight the morning of October 4th, 2024. These birds, both 2.5-year-old males, were hatched at Oregon Zoo’s Jonsson Center. With their release, there are now 18 condors flying over Yurok territory and the surrounding areas. These birds were originally going to arrive last year and be released with the 2023 cohort, B0 (Studbook 1140), B1 (Studbook 1148), and B2 (Studbook 1151), but were delayed due to Highly Pathogenic Avian Influenza (HPAI) vaccination efforts, so the Northern California Condor Restoration Program (NCCRP) were unable to release them last year. They were released into the flight pen on August 29, 2024. They integrated well with the other birds in the release pen, and after receiving their final vaccine boosters and radio and GPS transmitters a few weeks into their stay, they joined the rest of the free-flying birds upon the end of their acclimation period in the flight pen. Both birds left the trap early in the morning of October 4th and joined other free-flying birds in feeding at the release site. Crew will be closely monitoring these two birds in the coming days and weeks as they build up necessary flight skills and fully integrate with the flock. With the conclusion of the release season, our Mentor bird, Paaytoqin (Studbook 746) will be departing on Monday, October 7th, for a new assignment. Condor releases will continue in 2025. Please follow along on our livestream to watch the free-flying birds when they visit the release site to feed, bathe, and socialize. The Northern California Condor Restoration Program is a partnership between the Yurok Tribe and Redwood National and State Parks.

I love this story for a few reasons. First, it's about my favorite bird, the turkey vulture. It's also about camera trap photography, which I love. To have a photo of a vulture win a bird photography award feels special and meaningful. Even when we appreciate them for what they do for us, we don't tend to call them beautiful. But they are. They are beautiful, majestic, regal birds.

The Indian vulture collapse is one of the worst wildlife disasters in history, and I meet people all the time who have never heard of it. In a few decades, India lost nearly all of its vultures. That cascaded into hundreds of thousands of human deaths, billions of dollars in damage, and a cultural loss that can't even really be measured.

My latest for the Washington Post is about the value of vultures, in hopes that we appreciate ours a little more.

It's the most wonderful time of the year. That's right. It's finally Vulture Awareness Day.

Even if you don't recognize for the rest of the year what perfect, majestic birds these are— these climate and public health allies, these highest flying of all birds—today, look for them and thank them for their service.

On the heels of good condor news from California, awful news from Utah. in Zion National Park, the condor nicknamed 1K, because he was the 1000th egg hatched in the recovery effort, died of lead poisoning at 4 years old, about 5 yrs short of breeding age.

Wildlife reintroduction is complicated, but for condors, lead is really the main problem, along with the global avian flu pandemic that has killed so many birds over the past two years.
