"Robin's Nest Takes Priority Over Pickup Purchase: A Delightful Delay A would-be buyer of a pickup truck has been left waiting, but not for the usual reasons. The sale has hit a roadblock due to a tiny, feathered inhabitant - a robin's nest has taken up residence on the vehicle. Under federal law, it's a crime to disturb or destroy an active robin's nest, putting the buyer in an unexpected holding pattern. As the nest's occupants prepare to take flight, the buyer will have to wait until the robin's young have grown strong enough to leave the nest before the sale can proceed."
It’s against federal law to move or destroy an active robin’s nest, so the pickup's buyer has to wait until the hatchlings fly away.
