Do Blue Tits Snore?

rencontre femme tonnerre At about 11pm on 31/05/2012 I heard a hissing noise coming from the blue tit box. I didn’t think it was them as they were asleep and I’d never heard a noise like it before. I check everywhere and couldn’t see anything else. It was the nest with the mic in so I sat and listened inside. Sure enough the hissing came again and it was definitely from the nest box, but, the blue tits were still sleeping. Does this mean Blue Tits snore?
