Learn about the wonderful and fascinating lives of birds by exploring our datasets

Preview of the Species Bubble Explorer
Species Bubble Explorer
Every species as a bubble sized by body mass — pick what the x-axis, y-axis, and color mean and watch clusters and outliers glide into place, or jump straight to a hand-picked story.

Preview of the Traits Constellation visualization
Traits Constellation
A radial visualization of diet, habitat, body mass, and conservation status for every species.

Preview of the Weights of Birds chart
Weights of Birds
Compare the relative mass of every species with min–max weight bars for females, males, and unsexed birds — then switch to the Sexual Dimorphism tab to see how, and by how much, males and females diverge in size.

Preview of the Size & Life-History Scaling chart
Size & Life-History Scaling
See how body mass shapes a bird's breeding life — clutch size, incubation, fledging, broods, and productivity — with a brushable scatter plot.

Preview of the Migration Trends chart
Migration Trends
Watch 25 years of fall raptor counts from a real hawk-watch site (Illinois Beach State Park Hawkwatch) unfold season by season, in an animated Gapminder-style trend chart.

Preview of the Diet & Habitat Explorer
Diet & Habitat Explorer
Brush across body mass, habitat breadth, diet breadth, and specialization (ESI) to see how generalists and specialists trace different paths through every species' ecological profile — then switch to the Habitat ↔ Diet Flow tab for an illustrated Sankey diagram of which habitats and diets pair up most.

Preview of the Behavioral Trait-Syndrome Network
Behavioral Trait-Syndrome Network
A force-directed graph of how social, mating, nesting, and movement behaviors cluster together across species — drag a node to explore its neighborhood and see which traits travel as a package.
