Our Turkish Christmas Birds

Two birds have been sleeping in our vine outside our front door every night.  I have never seen anything like it.  I didn't know that birds actually get close together and snuggle.  It has been cold here - in the 30s most nights.  And our vine is just about bare at this point.  But these two birds get up there every night just after sunset and snuggle together until the morning sunrise.  When they are puffed up like in this photo they seem to be asleep or almost hibernating.  there eyes are closed and I can actually walk up to about a foot away to take a photo like this.  While we are going in and out the front door in the evening, we walk within three feet of them and they never move.

I'm not sure what type of bird they are.  Our Turkish shoeshine guy at the Medical Group, Jaf, tells me they are Nightingales.  They don't look like the Nightingales I see when I google them.  But perhaps they are some Turkish variation.
