Birdbase is a centralized resource for avian genomics and other aspects of avian biology. BirdBase Objectives: * Provide a community driven platform for information about bird genomes and genomics. * Stimulate scientific advancement by integrating information from a variety of bird species * Promote collaboration and cooperation between scientists using birds as model organisms and those studying agricultural traits of birds. * Help coordinate solutions to common issues such as gene nomenclature and ontology development * Provide a conduit for sharing reagents and protocols

BIRDBASE is a global avian trait database with data on 78 traits of all bird species (11,589), genera (2398), families (254), and orders (44) based on the most recent avian taxonomies published in October 2024 (eBird/Clements v2024), January 2025 (HBW/BirdLife 9.1), March 2025 (IOC v15.1), and including all the species in the first unified checklist of the birds of the world published in June 2025 (AviList).

We compiled species-level ecological data from a variety of published datasets, ornithological publications and the first author's field observations of over 9300 bird species. Data were primarily compiled from 367 ornithological sources, including regional books, field guides, focused datasets, and primary literature. Most of these data were collated from the Handbook of the Birds of the World/Handbook of the Birds of the World Alive, now Birds of the World, augmented with other sources including BirdLife International, the ornithological literature and our unpublished field observations.

The dataset is provided in an Excel file, with separate worksheets for trait values, trait definitions, nest details and data sources. The dataset is available in the Figshare repository for public use.

The database contains one row per species for all 11,589 species. Additional explanations for the database columns are provided in the Legend worksheet of the database Excel spreadsheet, which also contains both the database content and the source list as separate worksheets.

We included 78 traits in 10 major categories: conservation, geographic distribution, morphology, elevational distribution, habitat, diet, social behavior, reproductive behavior, demography, and mobility. Traits include conservation status (2024 IUCN Red List16), latitudinal distribution, biogeographical realm, island endemism, body mass, elevational limits, primary habitat, habitat breadth, primary diet, diet breadth, ecological specialization, sociality, clutch size, nest type and placement, and movement (Figure 2).

This dataset contains the predicted prices of the asset Bird Base over the next 16 years. This data is calculated initially using a default 5 percent annual growth rate, and after page load, it features a sliding scale component where the user can then further adjust the growth rate to their own positive or negative projections. The maximum positive adjustable growth rate is 100 percent, and the minimum adjustable growth rate is -100 percent.
