Watching Mason Bees enter and exit their home and discussing their habits

In early spring some bees started showing up on my property, this is a normal occurrence for me as I have built homes for them to lay their eggs in and repopulate the area. As you can see in the video they are quite excited about their homes and many are inside and you can barely see them, just their antenna sticking out. I discuss in the video their life cycle, habits and how they compare to other insects that use mud for their homes.

I used a Sigma 300mm lens to get some close ups, and it was the afternoon once the air warmed up outside.
