pyinaturalist

Introduction

iNaturalist is a community science platform that helps people
get involved in the natural world by observing and identifying the living things around them.
Collectively, the community produces a rich source of global biodiversity data that can be valuable
to anyone from hobbyists to scientists.

pyinaturalist is a client for the iNaturalist API that makes
these data easily accessible in the python programming language.

Features

• ➡️ Easier requests: Simplified request formats, easy pagination, and complete request
  parameter type annotations for better IDE integration
• ⬅️ Convenient responses: Type conversions to the things you would expect in python, and
  typed model objects (Observation, Taxon, etc.) with full IDE autocompletion
• 🔒 Security: Keyring integration for secure credential storage
• 📗 Docs: Example requests, responses, scripts, and Jupyter notebooks to help get you started
• 🧪 Testing: A dry-run testing mode to preview your requests before potentially modifying data
• 💚 Responsible use: Follows the
  API Recommended Practices without extra configuration;
  caching and rate-limiting features reduce bandwidth usage, errors, and unexpected throttling

Supported Endpoints

Many of the most relevant API endpoints are supported, including:

• 📝 Annotations and observation fields
• 🆔 Identifications
• 💬 Messages
• 👀 Observations (multiple formats)
• 📷 Observation photos + sounds
• 📊 Observation histograms, observers, identifiers, life lists, and species counts
• 📍 Places
• 👥 Projects
• 🐦 Species
• 👤 Users

Quickstart

Here are usage examples for some of the most commonly used features.

First, install with pip:

pip install pyinaturalist

Then, import and create a client object. This will be our main interface to the API:

from pyinaturalist import *
client = iNatClient()

Note: If you are looking for the lower-level API functions (without the client class), see
this page

Search observations

Let's start by searching for all your own observations. There are
numerous fields you can search on, but we'll just use user_id for now:

>>> results = client.observations.search(user_id='my_username')

The full response consists of Observation objects with numerous attributes, but we can use pyinaturalist.pprint() to print
out a condensed summary:

>>> pprint(results)
ID         Taxon                               Observed on   User     Location
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
117585709  Genus: Hyoscyamus (henbanes)        May 18, 2022  niconoe  Calvi, France
117464920  Genus: Omophlus                     May 17, 2022  niconoe  Galéria, France
117464393  Genus: Briza (Rattlesnake Grasses)  May 17, 2022  niconoe  Galéria, France
...

You can also get
observation counts by species.
On iNaturalist.org, this information can be found on the 'Species' tab of search results.
For example, to get species counts of all your own research-grade observations:

>>> counts = client.observations.species_counts(user_id='my_username', quality_grade='research')
>>> pprint(counts)
 ID     Rank      Scientific name               Common name             Count
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
47934   species   🐛 Libellula luctuosa         Widow Skimmer           7
48627   species   🌻 Echinacea purpurea         Purple Coneflower       6
504060  species   🍄 Pleurotus citrinopileatus  Golden Oyster Mushroom  6
...

The data will be in the form of
TaxonCount
objects:

>>> counts[0]
TaxonCount(
    id=48662,
    name='Danaus plexippus',
    preferred_common_name='Monarch',
    rank='species',
    count=13,
    observations_count=458712,
    ...
)

Another useful format is the
observation histogram,
which shows the number of observations over a given time interval. The default is month_of_year:

>>> histogram = client.observations.histogram(user_id='my_username')
>>> pprint(histogram)
Month   Count
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Jan     8       ████
Feb     1       █
Mar     20      ██████████

The raw data will be a dict, with either int or datetime keys, depending on the interval:

>>> print(histogram.raw)
{
    1: 8,  # January
    2: 1,  # February
    3: 19, # March
    ...,   # etc.
}

Create and update observations: authentication

To create or modify observations, you will first need to log in.
This requires creating an iNaturalist app,
which will be used to get an access token.

creds = {
    'username': 'my_username',
    'password': 'my_password',
    'app_id': 'my_app_id',
    'app_secret': 'my_app_secret',
}
client = iNatClient(creds=creds)

See Authentication
for more options including environment variables, keyrings, and password managers.
A keyring is recommended, which does not require passing credentials directly:

client = iNatClient()
# Creds will be requested from the keyring when an authenticated request is made
client.observations.create(...)

Create and update observations

Now we can create a new observation:

from datetime import datetime

new_obs = client.observations.create(
    taxon_id=54327,  # Vespa Crabro
    observed_on_string=datetime.now(),
    time_zone='Brussels',
    description='This is a free text comment for the observation',
    tag_list='wasp, Belgium',
    latitude=50.647143,
    longitude=4.360216,
    positional_accuracy=50,  # GPS accuracy in meters
    photos=['~/observations/wasp1.jpg', '~/observations/wasp2.jpg'],
    sounds=['~/observations/recording.wav'],
)

We can then update the observation information, photos, or sounds:

client.observations.update(
    new_obs.id,  # Use the observation ID from the result above
    access_token=token,
    description='updated description !',
    photos='~/observations/wasp_nest.jpg',
    sounds='~/observations/wasp_nest.mp3',
)

Search species

There are many more resource types available besides observations. Taxonomy is another useful one.

Let's say you partially remember either a genus or family name that started with 'vespi'-something.
The taxon search
can be used to search by name, rank, and several other criteria:

>>> results = client.taxa.search(q='vespi', rank=['genus', 'family'])

As with observations, there is a lot of information available in the response (Taxon objects), but we'll print just a few basic details:

>>> pprint(results)
ID        Rank     Scientific name    Common name
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
52747     family   🐝 Vespidae        Hornets, Paper Wasps, Potter Wasps, and Allies
84737     genus    🦋 Vespina
646195    genus    🪰 Vespiodes
...
