Project description
Xeno Canto API Client for Python
An intuitive, type-safe Python wrapper for the Xeno-Canto API.
Streamline your bioacoustics and machine learning workflows by searching, filtering, and processing wildlife recordings with full validation and IDE autocompletion.

Quickstart
Installation
It is highly recommended to use a virtual environment to manage your project's dependencies and avoid conflicts with system-wide packages.
Creating a virtual environment:
# Create the environment python -m venv .venv # Activate it (macOS/Linux) source .venv/bin/activate # Activate it (Windows) .venv\Scripts\activateFor more details, see the official Python guide on Virtual Environments.
PIP
pip install xc-api-py
Basic Usage
from xeno_canto import Client
client = Client(api_key='YOUR_API_KEY')
# Search for multiple species at once
recordings = client.search(
species_list=['Grus grus', 'Acrocephalus melanopogon'],
limit=50
)
# Download and organize automatically
client.download(
recordings,
grouping='species',
naming='catalogue'
)
Advanced Features
Bulk Downloading & Organization
The download method supports advanced path management and naming conventions to keep your datasets organized for machine learning or archival.
| Argument | Options | Description |
|---|---|---|
grouping |
'flat', 'species', 'recordist' |
Nest files in subdirs (e.g., genus-species/subspecies/file.mp3). |
naming |
'original', 'catalogue' |
Use uploader filename or standardized xc12345.mp3. |
target_dir |
str or Path |
If None, creates a timestamped folder: xc-recordings-YYYY-MM-DD... |
# Create a recordist-based dataset with standardized names
client.download(
recordings,
target_dir='./my_dataset',
grouping='recordist',
naming='catalogue'
)
Flexible Search
The search method supports iterative species lists, coordinate filtering, and streaming for large datasets.
# Search across multiple species with a global limit and streaming
rs = client.search(
species_list=['Passer domesticus', 'Passer montanus'],
country='israel',
limit=100,
stream=True
)
Data Return Modes & "Lean" Objects
You can control exactly what kind of objects the client returns using the mode and lean parameters.
The lean=True flag optimizes performance by filtering out dozens of metadata fields (like location descriptions, temperature, or uploader comments) and returning only the critical core needed for identification and file retrieval.
| Mode | Return Type | Best For |
|---|---|---|
dataclass (default) |
XenoCantoRecording |
Fast script performance |
pydantic |
XenoCantoRecordingSchema |
Strict runtime validation |
audio |
XenoCantoAudio |
Direct playback and processing |
dict |
dict |
Loading into Pandas DataFrames |
json |
str |
Raw archival/caching |
# High-speed search returning lean dataclasses
recordings = client.search(genus='apus', mode='dataclass', lean=True)
SoundDevice Playback
import sounddevice as sd
from xeno_canto import Client
client = Client('API_KEY')
# mode='audio' returns XenoCantoAudio objects
recording = client.get_by_id('XC125492', mode='audio')
with recording.load() as a:
sd.play(a.to_numpy(), a.sample_rate)
sd.wait()
BirdNET Integration
from birdnetlib.analyzer import Analyzer
from birdnetlib import RecordingBuffer
analyzer = Analyzer()
recording = client.get_by_id('XC779948', mode='audio')
with recording.load() as a:
# Segment audio for BirdNET (expects 48kHz)
arr = a.to_birdnet()
buffer = RecordingBuffer(analyzer, arr)
buffer.analyze()
print(buffer.detections)
