There are few things stronger than a mother's love her child. For one cow in southwest India, that unshakable bond seemingly transcends even death.

Four years after a bus killed her calf in a traffic accident, a cow in the country's Uttara Kannada district stills visits the spot where her child died every day, India's Public TV reports.

She waits for the very bus that took her calf's life, blocking the vehicle and following along its side, according to the news station.
