Oxpeckers and Mutualism

Nature shows set in Africa often show rhinos and other large mammals with small birds on their backs. They're oxpeckers — like the Yellow-billed Oxpecker pictured here. This relationship was long held up as a textbook example of mutualism. Oxpeckers feed almost exclusively on whatever they find... read more »

Birds' Sense of Taste

Even though it’s been known for many years that birds spit out caterpillars they find repellent, little research has been devoted to birds’ sense of taste. It wasn’t until the 1970s that a scientist found taste buds on the inside of a duck’s bill — more than 400 of them. An experiment with... read more »

Singer's Brain Changes with the Seasons

In higher animals, the brain is like a Lamborghini — amazing engineering, but expensive to run. In a human, the brain uses about 10 times more energy than other organs. A bird's system is exquisitely attuned to this expense. Several species, including Black-capped Chickadees, have adapted in... read more »

Speech and Birdsong - The Genetics of Vocal Learning

Some birds are born with the ability to sing. Others learn to sing while they're young — just like humans, who must learn to speak. It turns out that vocal learning in songbirds and humans may have more in common than anyone suspected. Recent DNA research reveals that songbirds and humans share a... read more »

Beak Meets Seed

Birds like finches, chickadees and this Northern Cardinal love sunflower seeds, but each species uses a different strategy to extract the meat. When a finch plucks a sunflower seed from the feeder, it uses its tongue to maneuver the seed lengthwise into a groove on its beak. As it closes its beak... read more »

Falcons, Parrots, The Tree of Life

Scientists have puzzled for centuries over how different groups of birds are related. Did birds that look physically alike, such as falcons and hawks, arise from a common ancestor, or did they reach those similarities independently? This line of inquiry was given an immense boost in recent years... read more »

Birds, Nests, and Camouflage

Bird nests can be hard to find, often hidden in plain sight. Is the clever camouflage simply the result of using building materials that the birds happen to find? A Scottish research team used birds popular in the pet trade, Zebra Finches, to try and find out. The team gave nesting Zebra Finches... read more »
