Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain eagles as a grouping of raptors, identify major kinds and species, relay biology, conservation and cultural roles from ornithological sources, and distinguish eagles from ospreys, hawks and vultures.

A large bird of prey of the family Accipitridae, informally grouping several genera including the sea eagles such as the bald eagle and white-tailed eagle, the booted eagles such as the golden eagle, snake eagles and harpy eagles, with powerful hooked bills, strong talons and keen eyesight, nesting in large eyries and producing eaglets; eagles are apex predators and national symbols, many were reduced by persecution and pesticides and have recovered under protection, and the osprey, listed as an alias, is a separate family.

What it is for: Not applicable; a group of birds.

It can be explain the grouping and kinds; identify species; relay biology and conservation; distinguish from related raptors.

Distinguishing features

Large size and power

Informal polyphyletic grouping

Apex predators

National symbolism

What it looks like

Large raptors with broad wings, hooked bills and heavy talons, often soaring.

Physical character

golden eagle wingspan: about 1.8-2.3 m

eagle species: about 60-70 count - depending on definition

How it is recognised

Large Accipitridae raptors called eagles

Sea eagles, booted eagles, snake eagles, harpy eagles

The osprey is a separate family; hawks and buzzards are smaller; vultures scavenge

What the second pass must settle

  • Should each eagle group be a separate entry?
  • How should ornithological databases be linked?
  • The registry entry has merged aliases including the osprey; should it be split off?
