Crows in Tokyo

Tokyo has a crow problem, according to a story today on NPR.

The crows fly into the city from the suburbs to feast on garbage. They build nests in telephone poles, sometimes stealing bits of fiber optic cable to construct them.

The city has tried eliminating open garbage and trapping and gassing the crows - an option too cruel for some.

Now a privately funded project is using a new tactic: natural predators.

An office block in Tokyo's Ginza shopping district hung hives holding 300,000 bees on its roof. The bees act aggressively toward the crows, perceiving them as a threat.

Plan Bee worked for that city block, but expanding the project seems impractical - unless Tokyo envisions itself the world's largest apiary.
