This I know comes rather late but in case anyone with a similar trip in mind wanders passed...
Olu Deniz itself seems to me to be a birdless waste - the odd Kingfisher, Common Sand, Y l Gull. Admittedly I've only visited the lagoon and not the ground beneath Baga Dag. I have seen Yellow-vntd Bulbul here though.
A couple of summers ago I stayed up the hill in Hisaronou at the Tayfun apts. I was chuffed to find that the only decent bit of habitat started at the end of the street we were staying on. This area of 'wasteground', arable land, horse paddocks and orchard and scrub lies behind the school and council yard. In August I failed to pass the 50 species mark but nonetheless walked the area every morning and thoroughly enjoyed the 'no pressure' feel.
All 4 shrikes were well represented. Cretchzmar's (must learn to spell that one day), Black-headed and Cirl Bunts, Sombre Tit, Middle and Syrian peckers, Tawny pip, Hoopoe, Roller, Olivaceous War and Turtle Dove.
Beyond, this area gives way uphill to typical pine forest with asia minor Long-tld tit and Great Tit, though interestingly, no Krupers ... that can't be right but my notes say it is.
Persevere here as it becomes birdless and pass, on your left, a very nice looking villa complex replete with deer and vines and gardens - looks a very nice place to stay, tasteful and quiet. Just as you've passed this is a gateway through which you will behold an almost 'biblical' valley. Searingly hot and arid (carry water). At the very end of this can just be seen the pile that is Fethiye - but you could be anywhere in the middle east. Yep you guessed it - I loved this place. Chukar, Subalp, Bl e Wheatear, Ruppell's, Red b Shrike and Long-l Buzz and not a soul. Were it not for the occasional barbed wire fence it could have been anytime in the last billion years or something mad like that.
Nothing earth shattering but not bad for the family hol where I'm expected back at the hotel in the same day.
Also worth mentioning is the hillock just off the high street. This is accessible from a track which is opposite the CEM chemist. On this tiny bit of scrub are Ruppell's Wars being ridiculously easy, Shrikes, Serin and Eastern Bonelli's.
