I love slow wildlife streams and consistently follow one at a time. Recently I found this stream from a puffin burrow on Seal Island (Maine, USA) managed by National Audubon Society.
There is currently one pretty big chick in the nest (named Burfle) that has just started shedding its fluff. You can also check out other streams from outside the burrow and the nearby ledge.

One of the most visually stunning movies I've ever seen. Visual poetry with little to no dialogue, mellowness and strange tension. Each frame is perfect. It's a must if you love slow cinema
