Access the AviList Global Avian Checklist in R

avilistr provides easy access to the AviList Global Avian Checklist, the first unified global bird taxonomy that harmonizes previous differences between IOC, Clements, and BirdLife checklists. This package contains the complete AviList dataset as R data objects, ready for analysis and research.

🌍 About AviList

AviList represents a landmark achievement in ornithology - the first unified global checklist of Earth’s bird species. Released in June 2025, it contains:

• 11,131 species across 2,376 genera
• 19,879 subspecies
• 252 families in 46 orders
• Unified taxonomy reconciling IOC, Clements, and BirdLife differences
• Rich metadata including nomenclatural details and external database links

🦅 Installation

Install from CRAN:

install.packages("avilistr")

Or install the development version from GitHub:

# Install from GitHub
devtools::install_github("dalyanalytics/avilistr")

# Or using pak
pak::pak("dalyanalytics/avilistr")

🦆 Quick Start

library(avilistr)

# Load the complete AviList dataset
data(avilist_2025)

# Or load the short version with essential fields only
data(avilist_2025_short)

# Get basic information about the data
nrow(avilist_2025)  # Total records
sum(avilist_2025$Taxon_rank == "species")  # Number of species
