Potter Wasp Nest

I love this nest. The name really suits it.

I've separated the pictures into two spottings since they are two different species of wasps.

I have them around the house all the time.. Never had any problem! Just annoying as the build the mud nest everywhere!

Thank you!
Are any of them dangerous?

Christiane is right for the second example.

Could be a Mud Dauber or Mud Wasps .. http://www.projectnoah.org/spottings/627...
