Well, seein' as no-one appears to have visited the site, here's a (sort of) account of what I found.
The reserve is at least as large (in area) as a large UK town and is well arranged with organised routes with all-weather paths. Actually the only bit of a downside was the surface of the paths as they were gravel covered and it was virtually impossible to sneak up on a bird unheard !
The reserve is well equipped with 10 hides plus a huge observation tower which would cost you 102 hot steps to climb to the top! The reward is a fabulous view.
On our two visits (remember ~ I was going to drag my wife along) we saw:-
(All species in
RED were new to me.)
White Storks aplenty; they were nesting throughout the reserve, some "naturally" in trees, others on provided platforms.
Little Egrets;
Cattle Egrets;
Spoonbills;
Black Winged Stilts;
Greater Flamingoes;
Grey Herons;
House Sparrows; (there doesn't appear to be much of a shortage of them in Spain)
Reed Bunting;
Greenfinches;
Goldfinches;
Serins;
Spotless Starlings;
Stonechats;
Blackbirds;
Blue & Great Tits;
Pied Wagtails;
Grey Wagtails;
A few Cuckoos calling ~ but always away in the distance! ;
Nightingales; ~ by the bucketload! It wasn't possible to walk more than about 50 metres without hearing one, and sometimes two, singing from deep inside a bush or tree. Although we must have heard scores of them, we only caught sight of about three of the little elusive blighters!
Swallows; ~ some nesting inside a few of the hides, and still feeding young.
Bee Eaters; ~ fabulously colourful birds. On our first visit we watched them hawking in groups of between 5 - 6 up to about a dozen, but on our second visit we only saw them individually.
Several Warblers, none of which gave us close, or long enough looks in order to make a stab at identification;
Kestrel;
Buzzard;
Yellow Legged Gulls; although they're more numerous within human habitations ~ just like Herring/Lesser Black Back Gulls in the UK.
Little Gulls;
Mediterranean Gulls;
Shoveller;
Mallards;
Coots;
Moorhens;
. . . a few different types of waders too far off to see clearly . . . I only had my binocs, while a spotting scope would have been very handy.
The following link has a more comprehensive list of the birds that may be seen on the reserve ~~~

We also saw some unidentified Frogs and Toads, Crayfish, Terrapins, Water Boatmen and other aquatic insects as well as several Butterflies and a host of wild flowers.
I did get some iffy video footage, and if I ever manage to upload and edit it I'll try posting it here. (Don't hold your breath, though!)
I can only add that if you're ever in that area of Spain, the Emporda Marshes are a must-visit.
