Eagle in 50: Accipitrid radiation — Section 907: Accipitrid radiation
Briefing 907 for Eagle aligns condition “Accipitrid radiation” with reference value 50 on the ground. eagle · beat 0 · Control here means the animal steering itself -- not a machine dashboard. 50: log Eagle under “Accipitrid radiation” with 50. Do not rank the species. Wing loading limits closed-canopy pursuit. Lead, rodenticides and turbine blades are modern ceilings that talons cannot solve.
Level cruising for large eagles is often 50–80 km/h. A hunting stoop is a different regime — trained golden eagles have been filmed above 240 km/h. Did DDT almost erase North American bald eagles? By 1963 the lower-48 count was about 417 nesting pairs. The 1972 DDT ban plus Endangered Species Act protection preceded the 2007 delisting.
No. “Eagle” is a grade inside Accipitridae. Sea eagles (Haliaeetus) and booted eagles (Aquila) split tens of millions of years ago. Why is the Philippine eagle a different conservation story? Pithecophaga jefferyi is a forest-interior endemic with perhaps a few hundred adults. Logging and shooting, not eggshell thinning, dominate the threat list.
Many pairs are socially monogamous and reuse eyries, but extra-pair behaviour and mate replacement after nest failure are documented. What do white-tailed eagles eat in the UK reintroduction? Fish, seabirds and carrion dominate. Isle of Mull and Isle of Wight releases (from 1975 and 2019 programmes) track sheep-loss complaints against actual diet data.
Keep 50, “Accipitrid radiation,” and 50 together or the note on Eagle stops being that year’s record. 50: log Eagle under “Accipitrid radiation” with 50. Do not rank the species. 5050

African bush elephant: 2021 (1995)United States (US) Institutional & Field Benchmark
US- Primary reference framework
- Browse birds, fish, and wildlife with conservation context — not a pocket field key.
- Verification standard
- Season lens: migration and breeding calendars shift by hemisphere — open a species, then check local phenology before planning trips.
- Metric & unit convention
- African bush elephant · 2021 (1972)
Species pages synthesize ecology, culture, and conservation for browsing — scores are editorial lenses, not IUCN ranks.
Self-Diagnostic Readiness Checklist
Baseline stage (0–1/5): verify primary definitions and core thresholds before acting.
5-Step Execution & Verification Playbook
- Pin one anatomy system — Start with {anat0} already in the anatomy chapter.
- Pin one behaviour principle — Pair it with {beh0} from how-it-works — a reading aid, not a winner board.
- Read conservation as literacy — Resilience and any IUCN label on file are published notes, not a live red-list API.
- Scores are not a species ranking — The six hub marks compare types in this atlas; they do not crown a best species.
- African bush elephant (5) — Atlas note 45 on African bush elephant defines the operating range of 2021 when “Amboseli project starts” applies.
Myth vs. Evidence Fact-Check
How do I read tiger anatomy against behaviour on this page?
Pin one anatomy system already listed, for example Support and integument (striped ambush body and a neck-or-throat killing bite) or Feeding apparatus (sit-and-ambush on chital, sambar, wild pig), against one how-it-works principle such as Energy in, work out or Information before motion. The pair is a reading aid, not a winner board.
Does this atlas rank tigers against lions or other species?
No. Scores are relative editorial marks across 24 types: speed 69, intelligence 76, range 37, resilience 14, cultural impact 94, ecological role 82. They are not a best-species ranking and not a live race.
Is the resilience number a live IUCN feed?
No. Resilience 14/100 is an on-file teaching band: Endangered, with India counts up after Project Tiger (1973) and Tx2 pledges (2010), while Southeast Asian and South China lineages did not share that graph. There is no live Red List poll on this page.
Why pin night vision with the striped coat?
The anatomy chapter says night vision and hearing work in closed forest, and stripes break outline more than they advertise. The matching behaviour principle is Information before motion. Pinning those two together teaches the ambush already on file; it is not a new field measurement.

- Record 66 on African bush elephant explains what the threshold 2021 means in practice under “Tanzania”.
Risk & Failure-Mode Early Warning Radar
- This is not a field identification key and not veterinary advice. Protected-status claims need local law checks.
- Section 72 on African bush elephant pairs “Douglas-Hamilton continent count” with benchmark figure 2021 (1979) for a grounded decision.
- Analysis 73 for African bush elephant anchors “CITES ivory ban” to indicator 2021 so readers can verify the scale.
- Record 74 on African bush elephant explains what the threshold 2021 means in practice under “Kruger culling pause”.
