Records of mean and standard deviation body masses

Source: R/data.R
raw_masses.Rd

A table of mean and (where available) standard deviation body masses for birds in the North American Breeding Bird Survey. The species list derives from SpeciesList.txt in Paradieck et al. (2019), filtered to remove species poorly sampled via the Breeding Bird Survey methods (following Harris et al. 2018) and augmented with all records, for each species, of mean (and, where available, standard deviation) body size found in the CRC Handbook of Avian Body Masses (Dunning 2008). There are often multiple records for a species, for different sexes or locations. Each record is included as a separate line.

Usage

raw_masses

Format

A data frame with 928 rows and 19 variables:

species_id

the species ID

english_common_name

the English common name, from Paradieck et al. (2019)

sporder

order, from Paradieck et al. (2019)

family

family, from Paradieck et al. (2019)

genus

genus, from Paradieck et al. (2019)

species

species, from Paradieck et al. (2019)

mass

mean body size for this sex/location, from Dunning (2008), in grams

sd

standard deviation of body size for this sex/location, if provided in Dunning (2008). Contains NA for records without standard deviation measurements

sex

sex, if provided in Dunning (2008). Conatins NA for records without values for "sex" in Dunning (2008). m or f

subspecies

subspecies, from Dunning (2008). Contains NA for record with no subspecies listed in Dunning (2008)

location

location, if provided in Dunning (2008)

name_mismatch

flag = 1, if there is a mismatch between the scientific name in Paradieck et al. (2019) versus in Dunning (2008). Typically these are small changes in spelling

name_notes

name as listed in Dunning (2008), if different from that listed in Paradieck et al. (2019)

not_in_dunning

flag = 1, if this species does not have a record in Dunning (2008)

close_genus

if a species is not in Dunning (2008), but a closely related species - e.g. recently renamed, or taxonomically divided between 2008 and 2019 - is, the genus of that closely related species.

close_species

if a species is not in Dunning (2008), but a closely related species - e.g. recently renamed, or taxonomically divided between 2008 and 2019 - is, the species of that closely related species.

close_subspecies

if a species is not in Dunning (2008), but a closely related species - e.g. recently renamed, or taxonomically divided between 2008 and 2019 - is, the subspecies of that closely related species.

close_species_notes

notes explaining the details of the "closely related" species designations
