Purpose and description
Enable an agent to recognise Alcedinidae as the kingfisher family, interpret records about its members at the correct biological scale, and select evidence-supported observation or conservation actions.
Alcedinidae is the bird family of kingfishers in the order Coraciiformes, comprising predominantly small to medium-sized predators with relatively large heads, long pointed bills and species adapted to aquatic or terrestrial prey.
It can be Resolve a kingfisher name or identifier against a documented family classification.; Attach an observation to the narrowest defensible member taxon while preserving identification uncertainty.; Compare member-specific foraging and nesting evidence to proposed habitat changes.; Separate breeding, non-breeding, transient and captive records before summarising distribution.; Retrieve the applicable species or population assessment before prioritising conservation work.; Determine whether an observation or intervention needs specialist identification, local permission or breeding-site precautions..
Distinguishing features
The referent must be a family-level taxon encompassing kingfishers, rather than the species Alcedo atthis commonly called 'kingfisher'.
Membership must follow an identified taxonomic treatment; a bird's common name or fishing behaviour alone cannot establish inclusion.
Field recognition should combine bill form, head and body proportions, feet, plumage and behaviour with a species-appropriate identification source.
Fish eating and proximity to water are not necessary membership tests: kingfisher lineages also exploit terrestrial prey, as documented in [Woodall's comparative study](https://zslpublications.onlinelibrary.wiley.com/doi/10.1111/j.1469-7998.1991.tb04750.x).
Kookaburras fall within the kingfisher family rather than forming an excluded lookalike group; see [the molecular phylogeny of Alcedinidae](https://academic.oup.com/auk/article/123/2/487/5562636).

Characteristics
- Taxon identity and placement
- Accepted family name; authority and year; parent order; classification source and version Fixes the meaning of Alcedinidae before records from different classifications are combined.
- External taxonomic identifiers
- Verified GBIF taxon key and NCBI Taxonomy ID, each with rank, matched name and retrieval date Supports reliable cross-dataset matching without confusing family identifiers with species identifiers.
- Biological record scale
- Family concept; descendant taxon; population; individual; observation Prevents an individual's condition or a species assessment from becoming a family-wide assertion.
- Identification evidence
- Photograph, sound recording, specimen or sequence linked to identification method, determiner and confidence Makes uncertain kingfisher identifications reviewable.
- Body dimensions
- Mass in g; body, wing and bill lengths in mm; measurement protocol, taxon, age and sex Supports identification and ecological comparisons without inventing one representative family body size.
- Foraging profile
- Observed prey groups, aquatic or terrestrial capture setting, perch or aerial search behaviour; unknown permitted Prevents management decisions based on the assumption that every kingfisher requires a fish-rich stream.
- Nest substrate and occupancy
- Recorded substrate; excavated or reused cavity; inactive, occupied, eggs, nestlings, fledged or unknown Connects breeding evidence to disturbance-sensitive sites.
- Life stage and sex evidence
- Egg, nestling, fledgling, immature or adult; sex determination method and confidence Keeps species-specific ageing and sexual dimorphism rules attached to the records where they apply.
- Range and occurrence context
- Member taxon, locality or geometry, date, season, native or introduced status, and wild or captive context Separates family distribution summaries from evidence of local establishment or breeding.
- Conservation assessment
- Assessed taxon or population; assessment system, category, geographic scope, assessment year and source Prevents assigning one descendant species' IUCN category to Alcedinidae as a whole.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 29 questions.
Family concept and membership Establishes which taxonomic concept the registry entry denotes and how its members are linked.
Alcedinidae is a family, so a species-style binomial or undated membership list would misrepresent the registered thing.
Name and placement
Records the accepted family name and its position in a named classification.
Family-rank anchor
The family-level interpretation is supported by [ITIS's Alcedinidae record](https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=178104); authority and crosswalks require explicit verification.
- Which classification release supplies the accepted family name, nomenclatural authority, year and parent order? provenance
- Which GBIF and NCBI records match that family concept rather than a descendant taxon? boundary
Descendant concepts
Tracks membership and disagreements among taxonomic treatments.
Versioned kingfisher membership
Subfamilies, genera and species should be linked under a dated treatment, with changes preserved rather than silently overwritten.
- Which subfamilies and genera are included in the chosen treatment of Alcedinidae? definition
- Do imported records use a narrower family circumscription or a different species split, and how are those concepts mapped? boundary
Recognition and biological scale Connects kingfisher recognition to evidence while keeping taxon and organism records distinct.
Common names, colourful plumage and fishing behaviour are insufficient to identify the family or a member species reliably.
Identification evidence
Uses combinations of characters interpreted for the candidate species and locality.
Diagnostic character combination
Identification should document the observed character combination and plausible alternatives instead of asserting a universal colour or bill rule.
- Which bill, body, foot, plumage or vocal characters support a kingfisher identification in this locality? definition
- Which alternative birds were considered, and what photograph, recording, specimen or sequence supports their exclusion? provenance
Age, sex and record subject
Constrains how observations of particular birds inform taxon-level statements.
Qualified organism observation
Ageing, sexing and measurements require member-specific criteria and an explicit subject.
- Does this statement describe the family, one species, a local population or an individual kingfisher? boundary
- Which species-specific evidence supports the recorded age and sex, and could immature plumage explain the apparent difference? measurement
Foraging, habitat and range Represents the ecological variation hidden by the common name kingfisher.
Habitat suitability depends on the member taxon's prey and capture setting, not merely the presence of water.
Prey and capture setting
Links feeding observations to prey availability and hunting conditions.
Member-specific feeding profile
Record diet and hunting method for the relevant taxon and season, allowing mixed or uncertain profiles.
- Which prey groups are documented for this kingfisher taxon, and are they captured in water, on land or in another setting? provenance
- What observations establish the availability of suitable prey and hunting positions at the site? measurement
Range and seasonal use
Distinguishes mapped distribution from a dated occurrence and from breeding occupancy.
Qualified range evidence
A family range summary should retain the member taxa and occurrence categories from which it was derived.
- Which member species supports this range claim, and is its presence native, introduced, vagrant or captive? boundary
- What dated evidence distinguishes breeding occupancy from seasonal foraging or a single passing bird? provenance
Nesting and recruitment Connects breeding records to nest-site requirements and observed outcomes.
Kingfisher nest-site assessment must accommodate different substrates and distinguish adult presence from successful reproduction.
Nest-site requirements
Records the actual nesting substrate and occupancy evidence for the member taxon.
Substrate-specific nesting
Reported kingfisher nest settings include earthen banks, tree cavities and termite nests; applicability must be checked by species. [Animal Diversity Web](https://animaldiversity.org/accounts/Alcedinidae/)
- Which nesting substrate is documented for this species at this site, and is the cavity excavated or reused? provenance
- What evidence establishes current occupancy without requiring intrusive inspection? measurement
Breeding stage and outcome
Separates reproductive stages and outcomes using dated observations.
Evidence-based breeding state
Nest construction, eggs, nestlings and fledged young represent different evidence states; disappearance alone does not establish success or failure.
- Which dated observations establish the current breeding stage and any fledging outcome? measurement
- How should observation timing and distance change while this kingfisher nest is active? action
Conservation and action conditions Connects threats and assessments to the correct kingfisher taxon, population and locality.
Family membership cannot supply a single threat category or justify an intervention for every kingfisher.
Assessment and threat evidence
Preserves assessment scope and tests locally relevant pressures.
Scoped conservation judgment
Conservation judgments need a named assessed subject, date and evidence connecting pressures to that subject.
- What is the latest verified IUCN assessment for the relevant member species, including assessment year and taxonomic concept? provenance
- Which evidence links local changes in prey, nesting substrate, habitat or predators to this population's condition? measurement
Intervention selection
Tests proposed actions against the member's ecology, breeding state and local requirements.
Justified kingfisher action
An action must address a documented requirement or pressure and specify how its outcome will be assessed.
- Does the proposed action address the limiting prey, perch, forest or nest-substrate condition demonstrated for this population? action
- Which local permissions, specialist involvement and breeding-season constraints apply before site work or bird handling? action
- Which observable change in occupancy, breeding outcome or habitat condition would demonstrate benefit? measurement
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
