Editorial Transparency

Sources & Corrections

CaRaptor's source register, correction log, and human-review queue. Updated as claims are verified, corrected, or retired.

This page documents the primary sources behind factual claims made across CaRaptor, records corrections to published content, and lists claims currently flagged for human editorial review before publication as verified reporting. The AB 1788 article is the editorial model: statute citation, effective date, exemption language, source note. All other articles are measured against that standard.

Human Review Required

Review Queue

Items that must be verified by a human editor before publication as reporting.

High priorityhrq-001

CDPR present-tense regulatory status

Location: Convene the Council — rodenticide topic prompt

The prompt states CDPR 'is reviewing' SGAR use. This is a present-tense regulatory status claim. CDPR regulatory activity is ongoing and subject to change. Must be verified against current CDPR records immediately before publication as reporting.

Medium priorityhrq-002

Peregrine dive speed — specific figure

Location: Ask a Raptor — Vera speed response; Meet the Raptors — Vera profile quote

The '200 mph' figure is consistent with Tucker (1998) theoretical model. The profile quote ('two hundred miles per hour') and simulated response ('approximately 200 miles per hour — that is the range documented in field measurements') require human verification that the Tucker model is being accurately characterized and that no more recent peer-reviewed field measurement supersedes it.

Medium priorityhrq-003

Kestrel decline — specific figure and region

Location: Meet the Raptors — Kael bio; Newsroom — 'Common Does Not Mean Stable'

The '50% in some regions' claim is qualified but requires a specific region, time period, and BBS stratum citation before publication as verified reporting. The eastern BBS region long-term trend supports the claim; the specific figure must be pulled from the current BBS trend estimator.

Medium priorityhrq-004

Sierra Nevada snowpack — specific figure

Location: Multiple pages — Aquila council responses; Riven council responses; Newsroom article deck

All snowpack claims are qualified. Before publication as verified reporting, the specific figure, baseline period, geography, and metric must be cited from NRCS SNOTEL or DWR data.

Medium priorityhrq-005

Barn owl rodent removal rate

Location: Convene the Council — Kael rodenticide response

The claim that barn owl families remove 'thousands of rodents per year' is qualified. The specific figure varies by study, territory size, and prey availability. A specific peer-reviewed citation is required before publication as verified reporting.

Medium priorityhrq-006

Sacramento-San Joaquin Delta — 'most hydrologically altered estuary'

Location: Convene the Council — Riven water response

Riven's claim that the Delta is 'the most hydrologically altered estuary in the western United States' is a superlative requiring a specific peer-reviewed or agency citation before publication as verified reporting.

Sources

Tucker, V.A. (1998). Gliding flight: speed and acceleration of ideal falcons during diving and pull out. Journal of Experimental Biology, 201(3), 403–414.

Theoretical model of peregrine stoop. Estimated maximum speed ~320 km/h (~200 mph) under optimal conditions. Does not represent a field measurement.

Orton, K. (2016). Peregrine Falcon (Falco peregrinus) stooping speed measured by GPS data logger. Unpublished field data cited in popular accounts; peer-reviewed publication status requires verification.

Widely cited field measurement of ~186 mph (299 km/h). Peer-reviewed publication status and methodology require verification before use as a primary source.

Editorial note

The '240 mph' figure circulates widely in popular literature but lacks a specific peer-reviewed citation. The character's quote ('two hundred miles per hour') is closer to the documented field measurement range. The simulated response has been qualified to reflect this. Human review required before any specific figure is published as verified reporting.

Correction Record

Corrections Log

All corrections preserve the original publication date and record the correction date, substance, and type.

corr-001·September 2026Factual qualification — unsourced specific figure removed

Location

Newsroom page — JSON-LD ItemList entry for 'The Water That Is No Longer There'

Original

Sierra Nevada snowpack has declined 30% since 1950.

Correction

Removed specific quantified figure from JSON-LD. Replaced with: 'Sierra Nevada snowpack has declined significantly since the mid-twentieth century according to multiple datasets. Specific figures vary by period, geography, and methodology.' The visible article deck already used this qualified language; the JSON-LD contradicted it.

corr-002·September 2026Factual qualification — unsourced specific figure removed

Location

Ask a Raptor — Kael insects response

Original

Insect populations in the San Joaquin Valley have declined by an estimated 40-60% since 1970.

Correction

Removed specific quantified figure. Replaced with: 'Insect populations in the San Joaquin Valley have declined substantially since the mid-twentieth century according to available monitoring data — specific figures vary by taxon, geography, and survey method, and the exact scale of decline in this region requires source verification.'

corr-003·September 2026Factual qualification — unsourced specific figure removed

Location

Ask a Raptor — Riven mercury response

Original

Hydraulic mining deposited an estimated 26 million cubic yards of mercury-laden sediment into the Sacramento River watershed.

Correction

Removed specific quantified figure. Replaced with: 'Hydraulic mining deposited enormous volumes of mercury-laden sediment into the Sacramento River watershed — estimates in the historical and regulatory literature vary; the specific figure requires source and period verification before publication as reporting.'

corr-004·September 2026Factual qualification — bare assertion qualified

Location

Ask a Raptor — Sable default2 response

Original

The Central Valley has lost more than 95% of its native grassland.

Correction

Replaced with: 'estimates in the conservation literature suggest more than 90% converted, though the specific figure varies by baseline year and methodology.'

corr-005·September 2026Factual qualification — unsourced specific figure removed

Location

Convene the Council — Kael rodenticide response

Original

A single barn owl family removes 3,000 rodents per year.

Correction

Replaced with: 'Barn owl families are documented to remove thousands of rodents per year — the specific figure varies by study, territory size, and prey availability, and requires source verification before publication as reporting.'

corr-006·September 2026Factual qualification — bare assertion qualified

Location

Convene the Council — Sable water response

Original

The Central Valley has lost 95% of its wetlands.

Correction

Replaced with: 'estimates in the conservation literature suggest 90% or more converted, though the specific figure varies by baseline year and methodology.'

corr-007·September 2026Factual qualification — specific figure qualified against sources

Location

Ask a Raptor — Vera speed response

Original

Vera dives at 240 miles per hour.

Correction

Qualified to reflect documented field measurements (~186 mph, Orton field data) vs. theoretical models (~200 mph, Tucker 1998). The character's profile quote ('two hundred miles per hour') is retained as closer to the documented range. The simulated response now distinguishes field measurement from theoretical maximum.
