Bird Behavior & Ecology: How Birds Live, Feed & Migrate

A lost Tropical Kingbird in a city park and a Glossy Ibis nesting in Maine look like the same story. They are not. Here is how vagrancy and range expansion actually differ, and why both are showing up more often.

Most songbirds migrate at night and navigate by the stars. We explain how artificial light disorients them, why strikes spike in spring and fall, and the one thing you can do.

Birds do not have a death wish. We explain why birds fly in front of cars, why they cannot dodge fast vehicles, and what keeps drawing them to the road.

Cats hunt birds on instinct, not hunger, which is why even a well fed pet kills. We explain the drive behind it, the scale, and the birds most at risk.

Glass is an invisible trap to a bird. We explain why birds fly into windows, the spring bird that attacks its reflection, and what to do when one hits the glass.

What actually kills the most birds, from outdoor cats to glass and traffic, and the small changes at home that add up across a continent.

The bird battering your window every spring is fighting its own reflection, not you. Here is why it happens, which birds do it, and how to break the cycle humanely.

An honest, ranked guide to stopping a woodpecker on your chimney. Diagnose why first, then work from the cheapest reflective deterrents to the durable fixes that actually last.

A wooden utility pole is a dead, soft, insect-filled snag standing alone in the open, which is exactly what a woodpecker wants. Here is what they do to poles, and the wildlife that benefits.

Metal is the one surface that gives the answer away. No insects, no cavity, so a woodpecker hammering a gutter or sign can only be drumming. Here is why, and why it rarely does harm.

A chimney is the tallest, most resonant drum a woodpecker can find, and the flue pipes the sound into the house. Here is why it happens and what it means.

A house offers a woodpecker everything it wants. Here is how to read where and when the pecking happens to tell which of the four reasons you are dealing with.

The calm, complete answer to why woodpeckers peck. The four reasons behind every bout, the surprising science of the skull, and how to tell which one you are hearing.
