WATCH LIVE: Peregrine falcons nest on Chicago high-rise

Three years ago, Dacey Arashiba lost the balcony of his high-rise condo to Steve and Linda - a pair of Peregrine falcons. A flower box on the 28th floor supplied the perfect nest for the pair, and their new family.

And it wasn't a one-time-deal, because year after year they keep coming back.

Naturally cliff dwellers, peregrine falcons have adapted to living in cities and using high-rise buildings for nests. They're also an endangered species, which means that when they landed on Dacey's balcony, there wasn't a thing he could do about it.

Luckily, Dacey was happy to have the company. Not only has he documented the birds' activities on his Instagram account, but he's also allowed professional nature photographers to live in his apartment to check out Linda and Steve.
