Add bird traits (BIRDBASE)

Joins BIRDBASE biogeography, conservation and life-history traits to a taxify() result by looking up accepted_name. Traits redundant with add_avonet() morphology are not carried.

Usage

add_birdbase(x, cols = NULL, verbose = TRUE)

Arguments

x

A data.frame returned by taxify().

cols

Which columns to attach: NULL (default) the curated set, "all" every column the source carries, or a character vector of names. See enrichment_cols.

verbose

Logical. Default TRUE.

Value

The same data.frame with additional columns:

birdbase_iucn_status

IUCN Red List category.

birdbase_realm

Biogeographic realm.

birdbase_latitudinal_zone

Latitudinal zone (1 tropical to 5).

birdbase_island_endemic

Island-restricted breeding (0/1).

birdbase_restricted_range

Restricted-range species (0/1).

birdbase_elevation_min_m

Lower elevation limit (m).

birdbase_elevation_max_m

Upper elevation limit (m).

birdbase_elevation_range_m

Elevational breadth (m).

birdbase_primary_habitat

Primary habitat.

birdbase_habitat_breadth

Habitat breadth (number of habitats).

birdbase_primary_diet

Primary diet.

birdbase_diet_breadth

Diet breadth (number of food types).

birdbase_specialization_esi

Ecological specialization index.

birdbase_clutch_min

Minimum clutch size (eggs).

birdbase_clutch_max

Maximum clutch size (eggs).

birdbase_nest_type

Nest architecture.

birdbase_flightlessness

Volancy (yes/no/partial).
