Each spring and autumn, millions of migratory birds travel
long routes between breeding and wintering grounds. At night
they often navigate by stars and Earth's magnetic field, but
city lights and tall glass towers create new hazards along
5
the flyways. Clear windows reflect sky or trees so strongly
that birds treat the image as open space and fly straight
into the glass. Collisions kill or injure countless birds
near office towers, apartments, and suburban homes during
peak migration weeks, when flocks move in dense nighttime
10
waves across cities that grew along traditional routes.
Researchers map strike hotspots by collecting carcasses and
using cameras that record impacts after dark. They find that
buildings with large uninterrupted panes cause more strikes
than those with patterned glass or external screens. Even
15
indoor plants placed close to a window can draw birds toward
a deadly reflection. Some cities now ask architects to use
bird-safe glass marked with dots or lines that people barely
notice but birds can see in time to turn aside. New rules
sometimes require these designs near parks and waterfronts.

Homeowners can help with simpler steps. Closing curtains at
dusk, moving houseplants farther from panes, and adding
inexpensive film or stickers reduce reflections without
blocking daylight completely. Leaving outdoor lights off or
using shielded fixtures during migration nights also lowers
25
attraction to dangerous facades. Volunteer teams walk
sidewalks at dawn to rescue stunned birds and report
locations that need redesign before the next busy season.
Protecting migrants matters because they control insects,
spread seeds, and signal ecosystem health across continents.
30
When communities treat glass as a shared conservation
problem—not only a building style choice—more birds complete
their journeys. Education campaigns, building codes, and
small household habits together can make city skies safer
for the next migration season, turning quiet windows from
35
hidden traps into passages birds can pass in safety.
