Russian ornithologist Sofya Rozenfeld 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 research expedition. The supplied report does not identify the court or provide the full terms of the ruling.
Russian ornithologist Sofya Rozenfeld has been sentenced to three and a half years in a penal colony over two donations of 1,000 rubles each to Alexey Navalny’s Anti-Corruption Foundation (FBK), according to a report by T-invariant translated and published by Meduza on October 14. Rozenfeld acknowledged making the payments but denied supporting extremism or acting with criminal intent; the sentence removes an experienced Arctic-bird researcher from her work and reflects the risks facing people prosecuted over contributions to the organization.
The case concerned transfers made in August and September 2021, before Russian authorities designated FBK an extremist organization, according to the report. Rozenfeld was charged with financing an extremist organization. She is 50 and holds a doctorate in biological sciences; the source describes her as one of Russia’s leading ornithologists, known for field research on Arctic birds and conservation work.
Rozenfeld told the court she had signed up for recurring donations and could not cancel them while away on an extended expedition with limited communications. Her defense presented evidence that she was conducting research in the field, including in remote northern areas, and argued she had no criminal intent. The report says she admitted guilt only in part. The precise ruling, the name of the court, and whether she will appeal are not provided in the supplied material.
According to the report, investigators searched her home after she returned to Moscow from a visit to her father in Israel in late 2025. Officers seized her phone and two laptops, and she was required to agree not to leave town without permission. Hearings took place over several months; friends said they expected a fine or forced labor to be more likely than a prison term. She was handcuffed after the final hearing, the report says.
The Cost to Arctic Research
Rozenfeld’s sentence matters beyond the prosecution itself because her work depends on sustained field experience in difficult-to-reach regions. She has studied Arctic birds, tracked geese by seaplane and taken part in expeditions, including research in the Polar Urals. Her imprisonment is likely to interrupt that work, though the supplied report does not detail the length of any interruption or the effect on specific research projects.
The case also illustrates how a small recurring payment can become the basis for a serious criminal prosecution when it is linked to an organization designated extremist by Russian authorities. Rozenfeld’s position was that the donations were intended to support anti-corruption work, not extremism. That is her stated account, not a finding that overturns the court’s sentence.

How the Donation Case Unfolded
Rozenfeld learned of the investigation on December 5, 2025, after returning from Israel, according to the account by T-invariant. Her father, Boris Rozenfeld, told the outlet that police searched her home shortly after she returned to Moscow in late November and took copies of her passports while leaving the documents with her.
The report describes delays to early hearings, including one postponement after a witness did not appear. Rozenfeld continued working and traveling on expeditions while the case proceeded. A friend told T-invariant that she had returned from an October expedition beyond the Arctic Circle, where she had been tagging musk oxen. These details come from people interviewed by the outlet; the supplied material does not include court documents or an official statement from prosecutors.
“I categorically deny, first, that I share extremist views and, second, that I had any criminal intent.”

Appeal and Sentence Details
The source material does not state which court issued the sentence, provide the written judgment, or say whether Rozenfeld’s lawyers plan to appeal. It also does not specify when she must report to the penal colony, where she would be held, or whether the sentence could be changed. Her account of limited connectivity during expeditions and the defense’s evidence are reported, but the material does not include the court’s full reasoning or a response from prosecutors.
The report describes the penalty as three and a half years in a penal colony. It does not provide a complete procedural record or independently establish how the sentence compares with other cases. Friends interviewed by T-invariant offered their interpretations of the trial and sentence; those views should not be treated as official explanations of the court’s decision.

The Next Legal Steps
The immediate next development to watch for is whether Rozenfeld or her lawyers challenge the judgment. No appeal plans or deadlines appear in the supplied report, so those details remain unconfirmed. A written judgment or statements from her legal team could clarify the court’s reasoning, the sentence’s start date and the practical options available to her.
Her imprisonment also leaves open what will happen to her ongoing research and conservation work. The report establishes that she has taken part in Arctic expeditions, but it does not name projects that would be affected or identify colleagues who will continue them. Further reporting from her lawyers, the court or her research institution would be needed to establish those effects.
