What is the flipping massive wall behind and left of El Triangulo at Desplomilandia near El Chorro? Looks absolutely covered in lines and seems to be twice the size of everything else around here, but nothing in the Rockfax guide... See photo- El Triangulo is the little wall in the bottom right!

I remember thinking exactly the same last time I was there, I think I found somewhere that said it was bird banned?

Edit: now I think about it I'm sure some friendly expats at the crag told me it was banned (due to birds) and wasn't developed.

That's Tajo del Cabrero. As ebdon says it's banned due to birds between 15 January to 31 June. Not sure how many routes there are or why it's not been developed - there are around 15 routes in that wall but most of them are trad. I have read that it's somewhat chossy

If you search in Google "tajo del cabrero croquis" you'll find a plenty of topos for the routes.
