Movebank REST API: Description of download interface to build calls to the Movebank database
Note: We are currently rate limiting requests to one concurrent request per IP and 20 concurrent requests total. A request remains active until the data transfer is complete. You will receive an error message if requests exceed the limit. Following an upcoming server migration we will offer more options. To request an exemption to this request limit, for example for educational purposes, or for questions, please contact [email protected].

Movebank's REST API allows access to pull data from Movebank using HTTP or JSON requests made in a web browser or through external programs such as R. All users of data accessed from Movebank must abide by Movebank's general terms of use and data policy. See Movebank's citation guidelines for guidance on how to cite data use. Below are details, example requests, and relevant information about security and access controls.
Movebank's data model is described in the user manual and Kranstauber et al. (2011). Definitions of data attributes are provided in the Movebank Attribute Dictionary. A machine-readable, persistent version of this vocabulary is published at http://vocab.nerc.ac.uk/collection/MVB. Use of the REST API to access data you are not already familiar with can lead to the download of data that excludes information that can be critical to understanding the data.
The following key concepts and attributes are important to be aware of. Also read about defining deployments and outliers in Movebank.
Animal, tag, and deployment identifiers: Movebank's data model associates each measurement (e.g. a GPS fix) with a tag, and tag measurements can be further associated with animals via deployments. Each animal, tag, and deployment has a
- a user-defined name: the animal, tag, and deployment IDs in Movebank, also referred to as the
individual_local_identifier
,deployment_local_identifier
ortag_local_identifier
. - an internal database identifier, not typically shown in Movebank: the
individual_id
,deployment_id
andtag_id
.
We do not encourage treating the internal database identifiers as a stable external reference to data, as these can change over time for various technical reasons. For example, new entities may be created and new internal identifiers assigned when
- the data owner deletes and re-creates animals, deployments, or tags.
- the data owner uploads reference data that re-creates animals, deployments, or tags.
- the data owner deletes and re-imports tags from live feeds.
- a data provider pushes updates to reference data that re-create animals, deployments or tags.
We advise obtaining the identifiers via the REST API using the examples below, matching the entities you are interested in by individual_local_identifier
, deployment_local_identifier
or tag_local_identifier
, and then using the corresponding individual_id
, deployment_id
and tag_id
where necessary.
For data owners, it is best practice to keep the individual_local_identifier
, deployment_local_identifier
or tag_local_identifier
identifiers—i.e., the animal, tag and deployment IDs—stable if you want to refer to these entities from outside of Movebank.
Local identifiers are unique within but not across studies. If you are combining data from multiple studies from Movebank using the REST API, we suggest referring to entities using a combination of the local identifier and study ID or name.
Outliers: Event records, most commonly location estimates, can be assigned as outliers in Movebank by data owners and providers using several different tools and data attributes. The results of all outlier management steps are summarized in the visible
attribute. We recommend including the visible
attribute in event-level requests using the examples below, in order to retain this information and the ability to exclude flagged outliers from subsequent use if desired.
Access to data is defined by data owners through their Permissions settings for each study in Movebank. If no username and password are provided, results will be restricted to data that owners have made publicly available. If a username and password are provided, results will be restricted to data that the user has access to. To access tracking actual data, including for visualization on external websites, the user (or the public) needs permission to download data. To request access to data, you can contact the study PI or Contact through Movebank and read advice on running collaborations using Movebank.
For data that are made available to others, the owners of each study in Movebank specify use conditions in the "License Terms" in the Study Details. In addition to user-specified conditions, the General Movebank Terms of Use apply.
To ensure that users are aware of the license terms for each study, users may be required to read and accept these terms of use prior to first downloading the data for a study. Once a user has accepted the terms of use for a study, they will not be required to accept them again unless the study owner changes the terms. These requirements can cause confusion when accessing data using the API. Options for accepting license terms include
- A user can log in to Movebank and accept the license terms for the study by initiating a data download prior to attempting to access through the API.
- Data managers can disable the requirement that users accept terms of use by unchecking the "Prompt users to accept license terms" box in the permissions settings for the study.
- Read and accept license terms using the API, as in the following example.
This example uses curl commands in Terminal on a Mac to accept license terms and access data from the published study (EBD) Lesser Kestrels (Hernández-Pliego et al. 2015).
-
Submit an http request as described below for a study and user requiring license terms be accepted, saving the terms as license_terms.txt (in html, search for "License Terms:") and specifying cookies to maintain a session in consecutive calls:
curl -v -u username:password -c cookies.txt -o license_terms.txt "https://www.movebank.org/movebank/service/direct-read?entity_type=event&study_id=16615296"
-
Create and print an md5sum:
md5 -r license_terms.txt
-
Submit an http request for the same study and user again, sending the cookie and including the md5sum (replace ### with the value from step 2):
curl -v -u username:password -b cookies.txt -o event_data.csv "https://www.movebank.org/movebank/service/direct-read?entity_type=event&study_id=16615296&license-md5=###"
Also see an example in Python added to this repository.
-
Request a token:
curl --user "username:password" "https://www.movebank.org/movebank/service/direct-read?service=request-token"
-
Use the token to request data:
curl "https://www.movebank.org/movebank/service/direct-read?entity_type=event&study_id=16615296&sensor_type=gps&api-token=<API-TOKEN>" > data-token.csv
The following are examples of how to access information from the Movebank database with HTTP requests. After providing valid credentials, these calls will return CSV files containing the requested information. Note that the results will be based on the information available to the user as defined by access permissions (see above). If downloaded files have no extension and you are unable to open them, add ".csv" to the filename.
You may want to query general information about what is contained in Movebank. You can obtain information about the following entity types in the database prior to specifying a specific study: study, tag_type, taxon. Note that the taxonomy in Movebank comes from the Integrated Taxonomic Information System (ITIS).
https://www.movebank.org/movebank/service/direct-read?attributes
This will open a list of available attribute names by entity type that can be used to further specify the example queries below. For definitions see http://vocab.nerc.ac.uk/collection/MVB. Note that the attributes id and local_identifier exist for the tag, individual and deployment entities. For event queries, use aliases with entity prefixes (e.g., individual_local_identifier
).

These results provide the study name (study
), the study's database ID (id
), owner-provided study details, calculated study statistics, and information about the access permissions of the user credentials used for the request. Here are some tips to interpreting the results, in particular if you are looking for studies and researchers that could be relevant to a particular project:
- For definitions see http://vocab.nerc.ac.uk/collection/MVB.
- You can create a link to a study page in Movebank using the
id
, e.g., for study 1338487915. - Summary statistics about the studies, contained in
number_of_deployments
,number_of_individuals
,number_of_tags
,timestamp_first_deployed_location
,timestamp_last_deployed_location
,number_of_deployed_locations
,taxon_ids
,sensor_type_ids
, are updated approximately once per day. - If
number_of_deployments
is empty butnumber_of_tags
is not, this can mean the owner has uploaded data but hasn't yet defined deployments on animals. See instructions for the owner to add deployments. - If
taxon_ids
is empty butnumber_of_individuals
is not, this means the owner has created animals but has not defined the species. If you are searching for specific species or taxa, we recommend also searching the table for common names that are usually stored in thename
orstudy_objective
. See instructions for the owner to assign taxa to animals. - If
timestamp_last_deployed_location
is in the future, this can indicate that tags have sent false timestamps through a live feed (i.e., the incorrect timestamp has been accurately received and imported from the tag) or that the owner mapped the timestamp format incorrectly when importing data files. See instructions for the owner to flag outliers manually or using filters and to fix incorrectly mapped values. - The
principal_investigator_email
is only provided in cases that the PI is not assigned to a Movebank account. See Security, access permission and authentication for more about contacting data owners.
You can filter the list of studies based on access, as set by the owner of each study in its Permissions settings. To determine your access rights, filter the list using i_am_owner
, i_can_see_data
, i_have_download_access
,
i_am_collaborator
, study_permission
, and/or there_are_data_which_i_cannot_see
. Here 'see' refers only to your rights to view tracks on the Movebank Tracking Data Map. You might have permission to see only the study details, view some or all tracks but not download data, or view and download some or all data. Studies you do not have permission to see at all will not be included in the list. You can contact data owners directly to propose data uses and request data sharing.
With both of these requests, the list of studies will be filtered to those for which the user is a Data Manager.

The list of studies will be filtered to those for which the user has permission to view data on the Tracking Data Map.
When you have a certain study of interest, you can access information contained in that study using the study’s Movebank ID (available in the Study Details). You can obtain information for the following entity types: study
, individual
, tag
, deployment
, sensor
, study_attribute
and event
. The event entity contains actual sensor measurements stored in study attributes, and one or more sensors can be associated with each tag. The deployment, individual, and tag entities contain descriptive information about the animals, tags, and deployments (i.e., periods over which tags are attached to animals) in the study. In Movebank we refer to the latter information as reference data. Important information about understanding these data are provided above.
For the examples that follow we will use the study Galapagos Albatrosses (study ID 2911040; Cruz et al. 2013) which is fully available to the public.

Tags can contain event data for more than one sensor type. Here you can see what sensor data are provided by each tag. Keep in mind that in Movebank, all attribute values for each imported event record (i.e., a row containing a timestamp in the original data file) are assigned to one sensor type. In some cases measurements for multiple sensors are contained in one line, in which case all of those measurements will be associated with the primary sensor as chosen by the user. For example, GPS units commonly provide tabular data that include a temperature measurement in the same line of data with each GPS fix. In this case both the temperature and location coordinates will have the sensor type GPS (sensor_type_id 653). To more thoroughly evaluate what kinds sensor information are contained in a study, you'll want to see what event data attributes are present.

By default, requests for event data return the event-level dataset (the “tracking data” for location sensors) limited to the variables timestamp
, location_lat
, location_long
, individual_id
, and tag_id
. This default request does not include
- Local identifiers specified by the data owner;
- The "visible" attribute, which is used to identify records that have been flagged as outliers;
- Additional data attributes often contained within the study, including for sensors that do not contain location coordinates (e.g. geolocators and accelerometers).
We recommend including individual_local_identifier
, tag_local_identifier
, and visible
in event-level requests, as shown in the following examples, to include identifiers and outlier flags as managed by the data owner. Read more about understanding data from Movebank above.

This could provide more information (and data volume) than necessary, so it is also possible to specify which attributes to include and in what order. The following example is a good minimum default set for location events. See “get a list of attribute names” above for available attributes. Note that filtering for some attributes may not work. Please contact [email protected] if you find an attribute that is not included in results.

Timestamps should be provided in the format yyyyMMddHHmmssSSS
(see list of letter meanings).
The 'reduced event' APIs allow calls to retrieve tracking data reduced according to 'reduction profiles'. (For REST API calls, additional attributes are provided for datasets < 800 records.) Data reduction can vastly reduce data transfer needs for many uses that do not require other sensor measurements or detailed movement data. Reduction profiles are defined by the following parameters for reducing spatial and temporal resolution:
- a name to identify the reduction profile
- minMillisBetweenEvents: minimum milliseconds between consecutive events per individual.
- minKmBetweenEvents: minimum distance in kilometers between consecutive events per individual.
- maxDurationDays: only keep the last 'maxDurationDays' days of data per individual.
- coordinateTrailingDigits: rounding of longitude and latitude and removes duplicates per individual.
Currently there are four profiles defined that reduce data to (1) daily events, (2) movements => 50 km, (3) the last 30 days and (4) events at 0.25-degree precision. The effect of these profiles will depend on the resolution, movement characteristics and temporal range of the source data.

The HTTP/CSV requests can be used to access Movebank data from R. The R package move2
provides flexible options for browsing and accessing data from Movebank in R using the REST API.
The following are examples for how to access Movebank data using JSON requests. This is currently designed primarily to allow tracking data to be displayed on external maps using the Google Maps API (see below). You will need the relevant study ID number and sensor type description in the database to access data (see above).
In the examples below, we use URLs that do not include usernames or passwords. In order to access data from a study without providing login information, the study must be completely accessible to the public as described above. Consider making data publicly available so that data can be accessed without providing any login information. Remember that making data available does not give others permission to use your data, and that terms of use still apply as described above. If data are public, the http request should begin with https://www.movebank.org/movebank/service/public/json?
, for example
https://www.movebank.org/movebank/service/public/json?&study_id=2911040&individual_local_identifiers=4262-84830876&max_events_per_individual=5&sensor_type=gps
If data are not public, the http request should begin with https://www.movebank.org/movebank/service/json-auth?
, for example
https://www.movebank.org/movebank/service/json-auth?&study_id=2911040&individual_local_identifiers=4262-84830876&max_events_per_individual=5&sensor_type=gps
The browser will prompt you to provide your Movebank credentials before proceeding with the request. Alternatively, you can provide user credentials using PHP that can be stored on your local server. For example,
<?php
$url='https://www.movebank.org/movebank/service/json-auth?study_id=16880941&individual_local_identifiers=Mary&individual_local_identifiers=Butterball&individual_local_identifiers=Schaumboch&max_events_per_individual=2000&sensor_type=gps';
$user=‘username’;
$password=‘password’;
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Basic " . base64_encode("$user:$password")
)
));
For non-public data, use the example above to modify your requests that use the examples below.

This example contains the minimum information needed to obtain data: a study ID, the animal ID defined by the data owner, and a sensor type. You can make several additional variations to this, described below. The timestamps are provided in milliseconds since 1970-01-01 UTC
, and coordinates are in WGS84.

Results will be in the same format as in the previous example, with a header like the first line in the previous example added before the first row of data for each individual.
https://www.movebank.org/movebank/service/public/json?study_id=2911040&individual_local_identifiers=4262-84830876&max_events_per_individual=10&sensor_type=gps
Results will be in the same format, but will be restricted to the most recent 10 records per individual. This can be used to reduce the page loading time.

Results will be in the same format, but will be restricted to events within the specified time range. This can be used to highlight (or exclude) a certain portion of a track or to reduce the page loading time. The timestamps must be provided in milliseconds since 1970-01-01 (converters are available online). All dates in Movebank are stored in UTC. Here we obtain locations collected between 2008-6-13 12:00
and 2008-6-16 12:00
