I had same issues with a manic road system that didn't allow for easy access to the hides, etc . Not very far apart, but no way to walk between them, thus requiring a maze of multi-lane highways.
You were brave to visit Qarn Nazwa at the weekend! Some disturbance mid week but much reduced compared to Thursdsy evening through to Saturday.
The Woodpigeons are introduced.Thanks Andy. Sorry, no photos of birds as I don't carry a camera, only on my smartphone.
I realised Rufous Turtle Dove wasn't common but I was still at the point of checking every Dove/Pigeon that moved in the park that morning and was frankly a bit more surprised by the Wood Pigeons.
As for the Egrets, I didn't realise their scarcity. I first noticed the two with Spoonbills, where the dark legs and yellow bill were noted, and was a bit uncertain. They flew and joined a Grey Heron, Great Egrets, a Little Egret and a Western Reef Heron in the same patch of water/creek in front of the mangroves - all distant but at the same range and seen next to and crossing in front of each other so directly comparable; they were between Little and Great in size but nearer to the former. They were all too far for the gape-line factor to be ascertained. I could of course be completely mistaken but I was certain at the time!
