What Hawk Mountain Sanctuary Association does
Mission
Hawk Mountain Sanctuary Association's mission is to conserve birds of prey worldwide by providing leadership in raptor conservation science and education, and by maintaining hawk mountain sanctuary as a model observation, research, and education facility.
As stated on its FY2025 Form 990.
Program
On its FY2023 return the organization reported starting a significant new program.
Hawk mountain received a grant to coordinate official hawkwatches at five sites along the kittatinny ridge and to promote education and outreach at each site. Sanctuary scientists worked to train seasonal and volunteer counters and educators and then synthesized the collected migration data, along with data of number of visitors, including number of visitors to north lookout at hawk mountain. Hawk mountain stewardship department produced a series of land conservation posters for use in public outreach and as an exhibit, and constructed a trailside kiosk to promote the importance of conserving the kittatinny ridge as a climate resilient landscape. New higher-level adult workshops seeking learning opportunities include raptor field techniques course, appalachian field institute workshops, and captive raptor management workshop. The state provided funding for hawk mountain to oversee the 3rd pennsylvania bird atlas, a five-year project to survey bird species' status during the breeding and the wintering season. Amber wiewel was selected to serve as bird atlas project coordinator and reports to the director of conservation science. Vulture road surveys were conducted along the kittatinny ridge after a decade-long hiatus to collect information on the wintering behaviors of vultures, highlight the birds as both year-round residents and migrants from the north. Staff also coordinated to complete road surveys in uruguay, venezuela, and saskatchewan, canada.
Its own explanation, from Schedule O of that return (Part III, line 2).
Background:hawk mountain sanctuary was founded in 1934 by pioneer conservationist rosalie edge as the world's first refuge for birds of prey. The sanctuary's founding was a turning point in reversing their widespread persecution. Today the association, incorporated in 1938, continues its pioneering work to protect birds of prey through education and public engagement, science-based conservation programs, including monitoring of raptor and other migrant populations, conducting scientific research, and through information sharing and providing professional conservation training.continued on schedule o.seven biologists and educators serve on its program staff, including three ph.d.-level scientists. In the last decade, the sanctuary has been at the forefront of globally important scientific efforts to monitor raptor populations and to study the dynamics of raptor migration and ecology. The sanctuary has emerged as a leader in global raptor conservation. Its acopian center for conservation learning serves as a hub for global raptor information, professional training, and studies, and its acclaimed international traineeship program has trained more than 500 young people from 76…

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 2020 to 2021, from $20M to $26M (+28%).
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: 2017 1% · 2021 6%. Grants only. Government contracts and fees sit inside program revenue.
72% of HAWK MOUNTAIN SANCTUARY ASSOCIATION’s revenue is contributions — about as donation-reliant as the typical peer (74% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 17 funders to 27 funders, grant income rose $138k → $406k.
18 of 64 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 58% 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 HAWK MOUNTAIN SANCTUARY ASSOCIATION’s funders (the co-funder graph). Top 30 of 64 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
HAWK MOUNTAIN SANCTUARY ASSOCIATION has a broad base — no single funder exceeds 23% of grant income, and it takes 5 funders to reach half.
the vertical line marks half of all grant income — 5 funders to its left
60% 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 HAWK MOUNTAIN SANCTUARY ASSOCIATION.
Largest funder’s share by year: 2017 24% · 2018 23% · 2019 28% · 2020 19% · 2021 20% · 2022 28% · 2023 32% — growing more concentrated.
“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 HAWK MOUNTAIN SANCTUARY ASSOCIATION's funders are still giving 3 years after their first grant; 66% 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
58% of HAWK MOUNTAIN SANCTUARY ASSOCIATION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $1.6M that is directly attributable, 59% of it comes from Pennsylvania funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $2.1M arriving through sponsors registered in 13 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.
