Russian ornithologist Sofya Rozenfeld has been 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 acknowledged making the donations but denied extremist beliefs and criminal intent, saying she could not cancel recurring payments while on a remote research expedition. The source report does not identify the court or provide a full account of the sentence’s appeal status.
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 the Anti-Corruption Foundation (FBK), the organization founded by the late opposition leader Alexey Navalny. 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 and published by Meduza on October 14.
The charges concern donations made in August and September 2021. Russian authorities designated FBK an extremist organization that year. The source report says Rozenfeld told the court she had signed up for recurring donations and was unable to cancel them while away on a lengthy scientific expedition, often in remote areas with limited communications.
Rozenfeld partially admitted guilt, acknowledging the payments while rejecting the prosecution’s account of her motives. In court, she said her reason for supporting FBK was to fight corruption, which she connected to harms she had encountered through her research and conservation work. The report describes her sentence as a penal-colony term but does not provide further details about the facility or sentence conditions.
According to her father, Boris Rozenfeld, investigators searched her home shortly after she returned to Moscow from a visit to Israel in late 2025. They seized her phone and two laptops and required her to sign a written pledge not to leave town without permission. The trial then proceeded over several months, with hearings postponed before the final session ended with Rozenfeld being handcuffed, her friends told T-invariant.
A Prison Term for a Field Scientist
The sentence takes an experienced researcher out of work focused on Arctic birds and conservation. Rozenfeld has a doctorate in biological sciences and has led or joined expeditions to Russia’s Far North, where fieldwork can involve long periods away from ordinary communications. The source report describes her studying birds, tracking geese by seaplane and contributing to efforts to protect rare species.
The case also shows how a prosecution over two small recurring payments can have consequences well beyond a financial penalty. Rozenfeld’s friends said she continued working and traveling on expeditions while the case was pending, but that she and her lawyers expected a fine or forced labor to be more likely than imprisonment. That expectation proved wrong. The report does not establish what effect her absence will have on particular projects, but her incarceration interrupts her research and conservation work.
For readers outside Russia, the case links criminal enforcement of the country’s extremist-organization designation of FBK with the personal and professional consequences for someone whose public profile is as a scientist. Rozenfeld’s position in court was that she supported anti-corruption work, not extremist views; that distinction was central to her partial admission of guilt.

From Recurring Payments to Trial
FBK was founded by Navalny, who died in prison in 2024. Russian authorities designated the foundation extremist in 2021, the same year as the donations at the center of Rozenfeld’s case. The prosecution described the payments as financing an extremist organization; Rozenfeld acknowledged the transfers but contested that she acted with criminal intent.
Rozenfeld learned of the investigation on December 5, 2025, shortly after returning from Israel, according to T-invariant’s account. Her father said the search and travel restriction followed soon after. Hearings began months later and were repeatedly postponed, including after a witness failed to appear, her friends said. Rozenfeld kept attending court and, according to those close to her, brought a packed bag because she knew detention was possible.
Her work required substantial time in the field. Friends told T-invariant that expeditions could last six months or more and take her to the Far North, where teams relied on satellite communications. They said she had documentation showing she was away on research work when FBK was designated extremist. The report does not include the court’s full written reasoning or independently assess the defense evidence.
“I categorically deny, first, that I share extremist views and, second, that I had any criminal intent.”

Appeal and Sentence Details Remain Unknown
The report does not say whether Rozenfeld has appealed, whether an appeal deadline has passed, or when she is expected to enter the penal colony. It also does not include the court’s full judgment, the prosecution’s detailed evidence, or a response from the court or investigators to the defense’s arguments.
Her account of being unable to cancel recurring payments and her claim that she had no criminal intent are attributed statements, not independent findings in the material provided. The report also does not specify which research projects may be affected, whether colleagues can take over her work, or what conditions she will face in custody.

Watch for Appeal and Research Impact
The next reported legal milestone would be any appeal or further court action; the source material does not say whether one has been filed. Updates from Rozenfeld’s lawyers or family could clarify the sentence’s status, its timing and the conditions of her detention.
Further reporting may also show how her imprisonment affects Arctic field studies and conservation projects in which she worked. Until those details are available, the confirmed development is the prison sentence and its stated connection to two 2021 donations.
