What Primates Peru does
Mission
In order to advance scientific and conservation goals Field Projects International FPI conducts tropical biology research at locations around the world. Our long-term educational programs and field courses support this mission by training the next generation of field scientists. FPI also consults for international partners in the planning and operation of field laboratories that monitor wildlife health and biodiversity.
As stated on its FY2025 Form 990.
Programs
Biological Research Capacity Building: Our senior scientists provide direct assistance and training in field laboratory design staffing acquisition of instruments and supplies and project development and implementation in order to expand One Health research capacity for international partners in regions of high biodiversity. These in situ labs feature genetic tools data systems and other modern technologies for wildlife population surveillance pathogen screening and toxicological investigations.

First we provide short intensive field courses of approximately 10-14 days in duration. Participants learn a variety of field biology research and laboratory methodologies on topics ranging from tropical biology and primatology to genomics and biodiversity monitoring. Second we organize long-term volunteer research assistantship opportunities. These programs are 5-8 weeks in duration and consist of assisting senior scientists and veterinarians at one of our field research locations. Participants gain experience with data and sample collection and analysis relating to a diverse array of flora and fauna.

Our primary research programs occur in the Peruvian Amazon where we carry out a long-term mark-recapture study of wild nonhuman primates bats birds small mammals and several other select species. Research topics range from long-term mercury bioaccumulation animal behavior and sensory perception to movement and feeding ecology.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $172k to $466k (+172%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 0% · 2022 11% · 2023 52% · 2024 28% · 2025 55%. Grants only. Government contracts and fees sit inside program revenue.
75% of Primates Peru’s revenue is contributions — about as donation-reliant as the typical peer (86% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2020 → 2023: the base broadened from 2 funders to 3 funders, grant income rose $97k → $227k.
1 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Primates Peru’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
Primates Peru leans on a few funders — its largest provides 59% of grant income and the top three 99%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
40% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Primates Peru.
Largest funder’s share by year: 2020 100% · 2021 100% · 2022 90% · 2023 96% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
61% of Primates Peru's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $109 arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
Primates Peru has grown faster than three-quarters of the 3,693 animals nonprofits its size.
