Let's write up a list of the places I will go to when all of this is over. Some of the places I know are exceptionally good and offer a 100% success rate for observations, this includes birds as rare as marbled ducks. Some are in the UK, some in Spain. Not coming back to Russia because I can see everything much closer.
Local destinations- Places in or around Cambridge where I can see interesting birds. Also need to collect Chicken of the Woods from Paradise LNR.
Thetford Forest- Pursue goshawks. Should be easy to see given I saw one in the area recently. Enormous bird even at a distance.
RSPB Lakenheath Fen- Mostly for the exceptionally reliable barn owl near the entrance
Wicken Fen NT- This is conditional on the presence of hen harriers and short-eared owls, to my knowledge neither has arrived yet, which is actually very worrying as there were five owls last year and a pair of harriers as well
Isle of Mull- Oh a variety of things to do here. 'Invade' the forests to collect mushrooms. One tour company offers exceptionally unusually reasonably priced bird tours, will take these in the summer to see golden eagles, white tailed eagles with a high success rate in their habitats. Really hoping to have a chance to observe the huge sea eagles at their nest- something possible with these guides and get better images than last time.
Vejer de la Frontera- Visit the town for the sole purpose of seeing northern bald ibis. These things nest right next to a very busy road, and are exceptionally, perhaps unusually, observable for wild birds
Alcala de los Gazules- Visit to see the enormous lesser kestrel colony
El Clot de Galvany- Location offers a 100% success rate for marbled duck observations. Also offers white-headed duck and other things, particularly in the summer
El Hondo- Spotted eagles in the winter
Los Montesinos and La Mata- Exceptionally reliable sites for Montagu's harrier
San Juan de la Pena- Lammergeier
Lo Chapineria- Spanish imperial eagle and black vulture
Alcoy- Griffon vulture
