Wildlife literacy programs aim to build compassion and knowledge about ethical and safe wildlife interactions. Proactive partnerships for wildlife serve as a core part of the conservation impact, and increased focus on species of special concern assures that resources are directed where most needed. Education of the public, of industry workers, of emergency first responders, of youth, and of the general public is essential to provide better longterm outcomes for people and for wildlife. The organization uses an expanding variety of inperson and virtual trainings, digital media, and live events to raise awareness, share best practices, engender hope, and give people actionable steps to minimize human impact to over 100,000 people annually. The organization also runs a bird helpline to answer questions and concerns from the public about birds they encounter.

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 2024 to 2025, from $1.5M to $2.3M (+53%).
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 3% · 2022 4% · 2023 4% · 2024 5% · 2025 7%. Grants only. Government contracts and fees sit inside program revenue.
81% of INTERNATIONAL BIRD RESCUE’s revenue is contributions — more donation-reliant than the typical peer (74% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 6 funders to 27 funders, grant income rose $22k → $356k.
16 of 68 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 49% 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 INTERNATIONAL BIRD RESCUE’s funders (the co-funder graph). Top 30 of 68 funders by total. 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
INTERNATIONAL BIRD RESCUE has a broad base — no single funder exceeds 16% of grant income, and it takes 7 funders to reach half.
the vertical line marks half of all grant income — 7 funders to its left
54% 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 INTERNATIONAL BIRD RESCUE.
Largest funder’s share by year: 2017 45% · 2018 48% · 2019 31% · 2020 16% · 2021 41% · 2022 44% · 2023 21% — 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.
How long its funders stay
50% of INTERNATIONAL BIRD RESCUE's funders are still giving 3 years after their first grant; 51% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
74% of INTERNATIONAL BIRD RESCUE's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.3M arriving through sponsors registered in 12 states 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.
