When Big Bird's performer is performing on location and cannot get a video feed, a small hole is made in the costume to allow him to see. In such cases, Big Bird must wear a necktie to cover the hole. This can also be seen in the "Sesame Street Live" shows. When Big Bird and Oscar the Grouch (both were performed by Spinney) were in a scene together with Spinney performing Big Bird, Jim Martin operated Oscar. When Vogel was operating Big Bird, Oscar was performed by Spinney as usual until 2015, when Eric Jacobson replaced Spinney as Oscar.
