Sofya Rozenfeld, a Russian Arctic bird researcher, was sentenced to three and a half years in a penal colony over two 1,000-ruble donations to Alexey Navalny’s Anti-Corruption Foundation. She admitted making the payments but denied extremist views and criminal intent, saying she could not cancel recurring donations while on a remote expedition. The sentence and her case’s impact on her scientific work are reported by T-invariant and translated by Meduza.
Russian ornithologist Sofya Rozenfeld has been sentenced to three and a half years in a penal colony for two donations of 1,000 rubles each to Alexey Navalny’s Anti-Corruption Foundation, which Russian authorities have designated an extremist organization. The 50-year-old scientist admitted making the payments but denied sharing extremist views or intending to commit a crime, according to a report by T-invariant translated by Meduza.
Rozenfeld is a doctor of biological sciences and a specialist in Arctic birds. Her work has taken her on research expeditions to Russia’s Far North, where she has studied bird populations and worked on conservation. The T-invariant report describes her as one of Russia’s leading ornithologists and says her research included tracking geese by seaplane and efforts to protect rare species.
The charges concerned two transfers of 1,000 rubles to the foundation in August and September 2021. Rozenfeld said in court that she had signed up for recurring donations but was unable to cancel them while on a lengthy scientific expedition without reliable communications. She acknowledged the payments while rejecting the prosecution’s characterization of her motives.
According to the report, Rozenfeld learned of the investigation after returning from a visit to her father in Israel in late 2025. Authorities searched her home, seized her phone and two laptops, and required her to sign an undertaking not to leave town without permission. Hearings followed over several months. Her sentence was imposed at the final hearing, where she was taken into custody, the report says.
A Prison Sentence for a Researcher
The sentence removes an experienced scientist from field research and conservation work, including studies that depend on seasonal access to remote Arctic locations. T-invariant’s report frames her imprisonment as a loss for Russian science, though it does not quantify the effects on particular projects or identify which research activities will now stop.
The case also shows how donations to an organization designated extremist by Russian authorities can lead to criminal prosecution, even when the amounts are small. Rozenfeld’s defense focused on her intent and the circumstances of the payments, including her extended periods away from communications. The court’s decision, as described in the report, did not accept those circumstances as grounds to avoid a prison sentence.

How the Donations Led to Charges
The transfers were made in August and September 2021. Rozenfeld told the court that she supported the foundation because she wanted to fight corruption, which she said she had seen affect scientific research and conservation. She denied that her donations reflected support for extremist views or any criminal purpose.
Her father, Boris Rozenfeld, told T-invariant that investigators searched her home shortly after she returned from Israel in late November 2025. A friend identified by the name Sergey said the hearings were repeatedly postponed and that Rozenfeld continued working and going on expeditions while the case proceeded. The report says she returned from a research trip to the Polar Urals on October 2, where she had been tagging musk oxen.
Friends quoted in the report said they expected a fine or forced labor rather than imprisonment. They also said Rozenfeld’s partial admission of guilt became a point of tension in court. Those accounts are attributed to her acquaintances; they do not establish why the judge selected the sentence.
““I categorically deny, first, that I share extremist views and, second, that I had any criminal intent.””

Questions About the Case’s Impact
The available report does not provide the full court judgment, the judge’s detailed reasoning, or information about whether Rozenfeld plans to appeal. It also does not give a confirmed account of when she will be transferred to a penal colony or the facility where she will serve her sentence.
The precise effect on her research is also not yet clear. The report describes her as a leading ornithologist and says her imprisonment deprives Russian science of her work, but it does not detail her projects, collaborators’ plans, or whether other researchers can continue them. The account of the trial and its atmosphere relies in part on statements from friends and family, whose identities are withheld or changed in some cases.
Appeal and Research Plans Ahead
The immediate next steps are whether Rozenfeld challenges the sentence and when authorities carry it out. The report does not say that an appeal has been filed or identify a deadline, so her legal options and schedule remain unconfirmed.
Her imprisonment is also likely to leave questions for colleagues and research institutions about ongoing Arctic fieldwork, particularly work tied to seasonal expeditions. No replacement arrangements or project updates are included in the report. Further reporting or statements from her legal team and scientific colleagues may clarify both the case’s next legal stage and the consequences for her research.
