What Delaware Ornithological Society does
Mission
Conservation Research Education of wild birds
As stated on its FY2023 Form 990-EZ.
Program
Grant 1 to Delaware Nature Society PO Box 700 Hockessin DE 19707 to underwrite a professional observer for their Ashland Nature Center Raptor Migration watch program and to independent observer at Cape Henlopen Hawk Watch Site
The program described on its FY2022 Form 990-EZ. Program spending in total: $0.
The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $291k to $316k (+9%).
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 2 reported years ran a deficit.
Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $5k → $5k.
1 of 3 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 DELAWARE ORNITHOLOGICAL SOCIETY’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
DELAWARE ORNITHOLOGICAL SOCIETY leans on a few funders — its largest provides 98% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left

Where its funders are
DELAWARE ORNITHOLOGICAL SOCIETY draws 100% of its grant income from funders outside Delaware, across 2 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $473 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.
