They do here too but my birds spend a lot of time just standing in the bowls when the heats really bad. I'd feel mean taking the bowls away completely...I can see standing in them is a pleasure for them. Maybe because we're a dry heat here. Wouldn't it be lovely if they caught and ate mosquitoesIm in Florida. We had heat indexes this summer of 114 and they were able to stay hydrated with just the nipples. I worry bowls would attract mosquitos here,

Bet they'd love an always clean water source too though.
