why so long between episodes?
As a duck mom, I really enjoyed this. Thank you!
Birdwatching has become a life-changing passion for many, and it’s fascinating to hear personal stories of how it can transform one's perspective on the world. If you’re interested in learning more about bird migration and conservation efforts, a great resource is teampiersma.org which is dedicated to supporting these efforts. Birds, like the migrating species that travel long distances, remind us of the interconnectedness of our world and the importance of preserving our natural environment. This connection between nature and conservation efforts can have a lasting impact on both personal and collective efforts to protect our planet.
