## Small bird, big world
A sparrow looks like easy prey, but birds carry a deep bag of defensive tricks. Camouflage is only the opening move.

> A small bird out in the big world might seem vulnerable or even defenseless against predators of birds.
## Blending into the grass
Streaky brown plumage lets a sparrow disappear into dry grass. Color and pattern do the work before any behavior has to.
## Alarm calls cross species
When a hawk or fox moves through the woods, birds sound off with special alarm calls. Other species recognize those calls and go on alert immediately.
## Safety in mixed flocks
Outside breeding season, birds travel in flocks that mix several species. More eyes spot danger sooner, and one alarm call spreads through the whole group.
## The broken wing act
Step near a killdeer's ground nest and a parent flutters off crying, dragging a wing as if it snapped. Once you have followed far enough, it recovers and flies.
## Other fakers on the ground
Common nighthawks and piping plovers pull the same stunt. A mourning dove flushed from a low branch may drop down and limp away too.
## Sounding like a snake
Baby burrowing owls buzz like a rattlesnake inside their burrow. Chickadees hiss from nest cavities, and nestling woodpeckers chatter like angry bees.
## Attack the intruder
Robins and mockingbirds dive at anything near the nest, pecking human heads. Red-winged blackbirds and kingbirds chase hawks and eagles, sometimes riding their backs.
## Mobbing blows the cover
Songbirds swarm a perched hawk or owl with scolding calls, and bold ones peck at its head. Even if it stays, it has lost surprise. The neighborhood knows exactly where it is.

## Poison in the feathers
The hooded pitohui of New Guinea carries toxins in its plumage, like those in poison dart frog skin. Several other tropical birds do the same.

> Any predator that grabs such a bird will quickly regret it.
## Vomit as a weapon
Baby herons and egrets poop on predators below and vomit on ones that climb close. Turkey vultures bring up carrion, and fulmars spray rancid stomach oil ten feet.
## Key takeaway

A small bird is rarely defenseless. Camouflage is just the start, and the loudest, weirdest tactics are often the ones that work.
