Could pidgeons who perch on my airiel or sky dish cause problems with my T.V.?

The newsagents have stopped delivering morning newspapers to my village, consequently I watch T.V. whilst I am having my breakfast. Unfortunately, I get lots on interference on the T.V. in my kitchen, however I usually watch T.V. in the living room at night. Tonight, I experimented by staying in the kitchen with the T.V. on and the reception was great. I have concluded that this is because the pigeons were asleep. Could the pigeons be the culprits, if so, how can I stop this.
