nearestobs: Recent nearby observations of a species

Description

Returns the most recent and nearest reported sighting information with observations of a species.

Usage

nearestobs(
  speciesCode,
  lat = NULL,
  lng = NULL,
  dist = NULL,
  back = NULL,
  max = NULL,
  locale = NULL,
  provisional = FALSE,
  hotspot = FALSE,
  sleep = 0,
  key = NULL,
  ...
)

Arguments

speciesCode

(required) Species code of the species of interest. Scientific names can be specified if wrapped around the species_code function. Defaults to NULL, so sightings for all species are returned. See eBird taxonomy for more information: https://ebird.org/science/use-ebird-data/the-ebird-taxonomy.

lat

Decimal latitude. value between -90.00 and 90.00, up to two decimal places of precision. Defaults to latitude based on IP.

lng

Decimal longitude. value between -180.00 and 180.00, up to two decimal places of precision. Defaults to longitude based on IP.

dist

Distance defining radius of interest from given lat/lng in kilometers (between 0 and 50, defaults to 25)

back

Number of days back to look for observations (between 1 and 30, defaults to 14).

max

Maximum number of result rows to return in this request (between 1 and 10000, defaults to all).

locale

Language/locale of response (when translations are available). See https://docs.oracle.com/javase/6/docs/api/java/util/Locale.html (defaults to en_US).

provisional

Should flagged records that have not been reviewed be included? (defaults to FALSE).

hotspot

Should results be limited to sightings at birding hotspots? (defaults to FALSE).

sleep

Time (in seconds) before function sends API call (defaults to zero. Set to higher number if you are using this function in a loop with many API calls).

key

eBird API key. You can obtain one from https://ebird.org/api/keygen. We strongly recommend storing it in your .Renviron file as an environment variable called EBIRD_KEY.

Value

A data.frame containing the collected information:

"speciesCode": species code

"comName": species common name

"sciName" species' scientific name

"locId": unique identifier for the location

"locName": location name

"obsDt": observation date formatted according to ISO 8601 (e.g. 'YYYY-MM-DD', or 'YYYY-MM-DD hh:mm'). Hours and minutes are excluded if the observer did not report an observation time.

"howMany": number of individuals observed, NA if only presence was noted

"lat": latitude of the location.

"lng": longitude of the location.

"obsValid": TRUE if observation has been deemed valid by either the automatic filters or a regional viewer, FALSE otherwise

"obsReviewed": TRUE if observation has been reviewed, FALSE otherwise

"locationPrivate": TRUE if location is not a birding hotspot

"subId": submission ID
