Russian ornithologist Sofya Rozenfeld, 50, was 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, according to a Meduza translation of a T-invariant report. Rozenfeld partly admitted making the payments but denied criminal intent, saying she could not cancel recurring donations while on a remote research expedition. The report says the court rejected defense arguments; further details about an appeal or her incarceration were not provided.
Russian ornithologist Sofya Rozenfeld, 50, 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 Meduza translation of reporting by T-invariant. The sentence puts a leading Arctic bird researcher behind bars for payments she said she could not cancel while away on a remote expedition, raising questions about the consequences for her scientific work.
Rozenfeld was charged with financing an organization designated “extremist” by Russian authorities, after two transfers to FBK in August and September 2021. She had learned of the criminal investigation on December 5, 2025, shortly after returning to Moscow from a visit to her father in Israel. Authorities searched her home, seized her phone and two laptops, and required her to obtain permission to leave town, her father, Boris Rozenfeld, told T-invariant.
Rozenfeld acknowledged signing up for recurring donations but said she was on a lengthy field expedition with no access to communications and could not stop the payments. She admitted guilt only in part. In court, she denied sharing extremist views or having criminal intent, saying her motivation had been to fight corruption. The source report says the court sentenced her after hearings that had been postponed several times.
Friends told T-invariant that Rozenfeld kept working and traveling on research trips while the case proceeded. Her latest expedition described in the report was to the Polar Urals, where she helped tag musk oxen; she returned on October 2. Her friends said she expected a fine or forced labor to be more likely than imprisonment. The report does not provide the court’s written reasoning or say whether she will appeal.
A Prison Sentence Puts Field Research at Risk
The sentence removes an experienced scientist from work that depends on long, specialized field seasons. Rozenfeld has spent much of her career studying Arctic birds, including through expeditions in Russia’s Far North. T-invariant’s report describes her as one of Russia’s leading ornithologists and says she holds a doctorate in biological sciences.
The immediate impact on her research is not detailed in the report. But imprisonment could interrupt ongoing studies and conservation work that rely on access to remote habitats and sustained observation. The case also shows how recurring political donations can carry criminal consequences under Russia’s designation of FBK, even where the accused says the payments continued while she was outside communications range.

From 2021 Donations to a 2025 Case
FBK, founded by opposition leader Alexey Navalny, was designated an “extremist” organization by Russian authorities in 2021. The two donations at issue were made in August and September of that year. Rozenfeld’s defense, as described by her friends, argued that she was away on scientific work when the organization was designated and lacked a practical way to cancel the recurring payments.
The investigation became known to Rozenfeld in December 2025, after she returned from Israel. Her trial hearings began months later and were postponed more than once, according to accounts from friends cited by T-invariant. The source report says she continued going on expeditions while awaiting the outcome, including a trip beyond the Arctic Circle shortly before the final hearing.
““I categorically deny, first, that I share extremist views and, second, that I had any criminal intent.””

Appeal and Research Impact Remain Unknown
The report does not say whether Rozenfeld has appealed, when she is expected to enter the penal colony, or where she will serve the sentence. It also does not include the court’s full written judgment, so the reasoning behind the sentence and the treatment of the defense evidence cannot be independently assessed from the material provided.
The longer-term effect on Rozenfeld’s research and conservation projects is also unclear. The source reports her sentence and career background but gives no details about who might continue her fieldwork, whether her projects will be paused, or how the ruling may affect her institute.
Watch for an Appeal and Sentencing Details
The next confirmed development would be any appeal filing or further information about how and when the sentence will be carried out. The source report does not identify a hearing date or state that an appeal has been filed. Updates from the court, Rozenfeld’s lawyers, or her research institute could clarify both her legal options and the status of her scientific work.
