There's a wide range of really great wildlife in this region. Some of the main wildlife targets will be Iberian Lynx, Wolves(!), Otters, Wild Boar, Mouflon and Red Deer - early days of planning yet, so may be more...
Bird-wise I'll be targeting Spanish Imperial Eagle, Golden Eagle, Black Vulture, Griffon Vulture (and Ruppell's too...?), Egyptian Vulture, Black-shouldered Kite, Purple Gallinule, Marbled Teal, Crested (Red-knobbed) Coot, Northern Bald Ibis, Red-necked Nightjar, Iberian Woodpecker, Iberian Shrike, Iberian Magpie, Great Spotted Cuckoo, Common Crane, Audouin's Gull, Sandgrouse, White-headed Duck, Black Wheatear, Great and Little Bustards, Eagle Owl, Scops Owl, Rock Thrushes.... and a lot more.
On top of the above there should be some cool raptors passing through such as Bonelli's, Booted, Short-toed Eagle, Montagu's, Marsh and Hen Harriers (Pallid too?), Black and Red Kites, Osprey and Lesser Kestrel.
Should hopefully be a good range of other migrants too, such as Crakes, Hoopoe, Bee-eaters, Rollers, Swifts, Shrikes, Orioles, Larks, Chats, Wheatears and Warblers... southern Europe in early-April could be interesting... certainly very exciting!
Area I'll be exploring.... (not my picture).
