I've been watching eagle and osprey cams a LOT lately. Those babies are so adorable but also, it's quite the experience watching a nest from the eggs being laid to offspring fledging. There can be great joy and also a lot of heartbreak because this is nature happening live in real time and in many cases, humans aren't allowed to intervene.
There are many more nest cams available depending on the season, location, and species. You may end up with several lists of cams like me and not enough time to check them all. I love that we can peek into their world in a safe way and can learn about them, chat with others about them, and just watch them do their thing anytime.
