Newborn to adult in 12 days: Robins nest time-lapse

A mother bird feeds her baby robins as they grow from balding to feathered and eventually ready for flight in this time-lapse video.

The now empty nest was filmed over a period of 12 days last May (2018)
The couple discovered the nest under the porch of their Washington home in Port Hadlock, catching the babies early on in their development as robins leave the nest at around 13 days old.

The mother bird can be seen eating the babies poop, which robins only do when their babies are very young and eventually moving on to taking the poop away and dropping it as they age.
